Paid tutorial "Set Sphere Collider. Make it big. Aggro anything that enters it" CZcams tutorial remakes AI from The Division 2 and does it in a way even my oonga boonga brain can digest. Well done and you have my thanks and admiration.
Took me a few times to re-read to understand what you meant. It's very true. I've spent thousands on courses and very few really went into the perception systems as detailed as this.
Amazing tutorials, are so helpful. I have a few recomendations: 1. You could use a function to Get the Stimulus Class and its easier to handle the logic. 2. To change the debug input go to Project Settings - Engine - Gameplay Debugger 3. To re-enable the Print String functions write "EnableAllScreenMessages" on the console command at the bottom of rhe editor Thanks for the tutorials, keep going 😁
just finished this one !! THis is amazing i was able to add noises do different things in the game, for a example if you pick up something and it's loud and the enemy is in the other room, he can hear you and comes to the room to investigate !! This is so cool, out of all tutorials i've seen in the last 2 years on unreal, your way of explaining and showing this is the best
Hey! I'm really glad to hear that you found it helpful and that you're able to implement those features in your game 🙏 Thank you for your kind words, it means a lot to me! Keep up the great work! 😊
Insanely helpful tutorial. I especially appreciate how much you showed off the AI debugging tools. I can't thank you enough for all the work this series must have taken to put together.
Without exaggerating, this youtube channel is frustrating... To see such a high quality of video on such a complicated subject (at least for me, the subject of AI is something that's not usually dealt with in such depth on CZcams or even on the training courses I've taken on Udemy) is simply amazing. (When I compare this tutorial with the majority of paid training courses... I'm completely impressed) Thank you, you really help me to understand this subject much better, I had lost hope of finding a tutorial of such quality!
You are very kind Eurg, thank you so much for the support. I do put a lot of effort into making these videos without much expectations in return, so it really motivates me to see comments like this and to see that it's helping people. I hope you enjoy the rest :)
First of all thank you Ali for these tutorials honestly I have watched a lot of different CZcamsrs and their tutorials and yours is the best. Also for anyone running into the same issue I was having with the damage perception not showing in the debugger. First make sure you have a value for the damage amount. Second I had two ai in my level and I believe it did not know which one I was trying to damage and so nothing registered. Once I deleted one of them from the level it worked. Probably need a tag or id for each enemy or overlap event to let it know which is being damaged.
Thank you so much for your kind words! I'm glad you found the tutorials helpful. Also, thanks for sharing the tips on resolving the damage perception issue! 🙏

The quality of your tutorials is really incredible, I'm amazed by the level presented in your videos. Honestly, the subject of AI is not an easy one to tackle, and yet you're very pedagogical and really manage to explain things precisely. Thank you very much for this excellent tutorial.
One of the best tutorials I've seen in UE5, even with my custom enemy with custom animation bps and player character I'm able to do everything correctly. Love this series! Also "If the opponent is.. dead for example they shouldn't attack me" cracked me up a little:)
Thank you! I'm happy to hear that you found the tutorial helpful and that it worked with your customized setup. Glad you enjoyed the series, there are definitely some funny moments in there that weren't scripted 😂
All of your tutorial are amazing and your work is incredible. Like in this video, for my game project i just need the sight, and no need for the rest, and it still work perfectly
Thank you so much for your kind words! I'm glad to hear it worked well for your project. If you have any questions or need further assistance, feel free to ask 🙏
i don't understand why dude has 7k subs other channels can't do half of this dude does but they have around 50-80k subs with those funny open/close function BP's amazing man can't believe
As well as being a fantastic guide to the AI system in Unreal, These tutorials are an absolute goldmine of tips, techniques and best practices. Really useful stuff man. Can't thank you enough!
4:26 For people having issues with their apostrophe key not showing up debug AI menu, it turns out that you have to change your keyboard settings on your computer's operating system. The keyboard on your OS needs to be set at US Standard. Anything else and Unreal most likely won't register it. Hope it helps.
@@emmanuel.tavares If you're stil stuck on this, you'll have to go to Project Settings > Engine > Gameplay Debugger > Input and all those characters are there if you need to change them
These keep getting better. Gonna follow the whole series and see where I end up. It would have been nice to have a reset timer on the attacking state once Line of Sight was broken for so long. I assume this can be done threw the behavior tree. gonna play around and find out before the next video!
Great series! I do have a suggestion though for anyone following the tutorial. There is already a function which pretty much does what is implemented with "Can Sense Actor". Its called "Get Currently Perceived Actors" and lets you choose a "Sense" to get actors for. This should be much faster than looping through the senses for each actor.
Perefect! Everything worked very smoothly without bugs ;D And I even managed to implemented the preseption system to work with the previous created abilities from AOE and Projectiles tutorials ;D Which shows me that I'm actually learning something and not bluntly following your steps. This for sure speaks for your teaching methods! Cant wait to continue after dinner :) cheers!
Hey, that's fantastic to hear! I'm thrilled to hear about your successes. It's great to know you're learning and adapting the knowledge. Enjoy your dinner and looking forward to hearing about your progress after! Cheers!
Hey, thank you so much for your kind words! I really appreciate the support and I'm thrilled to hear that you're finding the tutorials helpful. Will definitely continue to create more content for you all! 🙏
you are doing an amazing job, your tutorials are extremely good, I've watched a lot on unreal tutorials and yours are my favorite, logical design, great approach, very well explained, even the pronunciation is top notch, hope you will get the appreciation you deserve. thank you 🙏
This is by far the best tutorial on enemy AI , thank you so much, on every tutorial i have an issue where AI bump into each other when fallowing the player, i hope you can touch on that in this series, 🙏
Thanks alot Ashen! I briefly touched upon the subject of having many enemies in the level, and that for that use case you should probably use the "Detour Crowd AI Controller", but I will try to touch upon it nearing the end
this is what i need an in depth series on 1 certain thing not one 10 minute tutorial on how to do a simple behaviour tree then not knowing how to bug fix and solve issues along with expanding the tree
Really glad you liked it. I indeed try to go in depth and actually teach a subject, so that following my tutorials means you can create your own and not just copy and paste my code
@@AliElZoheiry exactly! I’m not using third person template And I have tried but I cannot figure out how to do Ai animations, the animation blueprint graph has to be set up differently to pawn and I can’t find anywhere how to fix it
This is so complicated and yet you deliver the best lessons that can really teach someone. I've never created an AI before but with your tutorials I can understand the logic behind it and do something on my own. Thank you for such a great work! Also I wanted to ask about AI. So I want to AI to stop chasing/attacking me after I go out of sight radius, what's the best and optimal way to do this? To create another state when the enemy lose player and then create a Selector with condition in Attacking Sequence right before FocusTarget where I check if he's lost the player or not? Or maybe there's better and easier way to do that?
Hey! Thank you for your kind words, I'm really glad to hear that my tutorials are helping you understand AI better 🙏 For your question, I implemented that behavior in part 9 of this series czcams.com/video/U9WionHmfCM/video.html
Thank you for the kind words! I'm glad you found the tutorial helpful and easy to understand. If you have any more questions or need further assistance, feel free to ask!
Great Video as usual. edit: Ok you'll cover this in a later video. Enemy should return to passive state if he can't see the player anymore. Did you cover this behaviour in the video? I guess we need to create another handle for that.
great tutorial, really helpful and very well explained! Keep going with the hard work and if you ever make a tutorial about local co-op with various gamepads on UE5 or online multiplayer using EOS on UE5 that would be really fun and interesting to watch!!
Hey amazing tutorial and I can't wait to watch the rest of the series. I was wondering how to make the AI enemy to stop chasing and attacking the player once out of sight, returning his passive state. Please let me know if you know how this can be done
Probably the highest quality tutorial I've ever seen. I love your vids!! One question tho, when I'm behind a wall and I make a sound, my AI is stuck in the Move To task and he just stands in place. I don't know why, same thing happens when damaging him from behind the wall I followed every single one of your steps and re-watched that part countless times
Hey there, thank you so much for your kind words and support! Not sure what the issue is, because the MoveTo shouldn't care about line of sight, as long as there is a path from the enemy to the player, the MoveTo should work correctly
@@AliElZoheiry I'm so dumb, it was a problem with the nav mesh not covering the area I was testing in... it's always those small things that mess me up haha. Thank you for your help man, I'll definitely keep watching your videos and you already have my sub!
Teacher your Perception tutorial are amazing. Even complicated config function, You explain it very clearly even newbie like me can understand what this function can do. Also what is different about [Target] and [actor] in function Can Sense Actor mean, Isn't it the same that refer to self? PS.I just finished half of the Part 3 on to the set up thing and I got a big question in my head when teacher mentioned about C++ , So in the real process in making the game do I need to learn C++ to improve this function? Or I need to learn coding to understand more complicated thing ,Please guide me to the right path .
Hey, thank you for your kind words and your questions. I'm glad to hear that you're finding the tutorials helpful. Regarding your question. "Self" doesn't refer to the actor, self always refer to the current class you're in, so in the AI controller, self is a reference to the AIC_EnemyBase controller. Regarding C++, generally speaking, yes C++ will be required for working in actual company that uses Unreal Engine. Even though there as games built fully using Blueprints, C++ is required for performance optimization and low level systems building
Make sure you are the server when you fire Make Noise node, otherwise it will not work. Also, if the print text does not work, instead restarting the engine, you can type EnableAllScreenMessages in the game console and you are good to go
This variable is automatically set by the engine when you call "Run Behavior Tree" in the AIController, the engine then get's the blackboard that is associated to that behavior tree and set's that variable's value.
You're welcome! To detect multiple sounds, you follow the same approach, just call the Make Noise function whenever you want to trigger a sound that the enemy Ai can hear
Hey Ali, every time the enemy senses anything, it stacks. For example, if it sees me and hears me at the same time, when it sees me again, it will think it hears me and sees me. I'm wondering if you could have any idea what is going on. Love your tutorials. Edit: I think it was solely a problem with the print strings, because it hasn't affected gameplay to my knowledge.
Hey there! Thanks for sharing your experience. It does seem like the issue might be related to the print strings. It's great to hear that it hasn't affected gameplay. Keep an eye on it, and let me know if you need any further assistance. Glad you're enjoying the tutorials!
Noice xD havent completed the ai but the other videos are easy to understand xD. Whats the next series about skill tree :D love that or maybe recreating game mechanics :)?
If anyone is getting errors when testing if the AI will see or hear you and go after you that deals with the blackboard returning none - just add an "? is valid" node before whatever the blackboard is connected to and plug the blackboard variable in there and it will work. It just needs to check before running the loop.
I love your content! It’s been incredibly helpful for me as I transition from Unity to Unreal after their recent scandal. However, I’ve noticed you say “erm” quite frequently, and it can be a bit distracting. Your insights are really valuable, so I thought I’d mention it in case it’s something you want to work on. Thanks for all your hard work!
Thank you so much for your feedback! I really appreciate your support and I'll definitely work on improving that. I'm glad to hear you find the content helpful as you transition to Unreal, and I'll keep working hard to provide valuable insights!
In the "responding to sensing an actor" section why not just use the "On Target Perception Updated" node? I am still new to this, so I may be missing something, but it seems a lot easier that way. My understanding is that that node gives you a separate call for each time an actor is sensed, so you would not need to loop through an array each time.
Hey there, indeed it seems that it is easier to use, but at the time of making this video, I had some issues with "On Target anything.." I hope that by now they fixed those issues, but also using "On Perception Updated" isn't that much more complex, and gives us control over how to deal with each actor
Love your tutorials! Hands down the best tutorials regarding enemy AI in CZcams. I have just one question. How do I allow interruptions in the investigating state? For example, let's say you make a sound and the enemy begins to approach the area of the sound. If you create another sound at another location, I want the enemy to stop their route to the 1st sound and make way to the 2nd sound. I can't do that with the behavior tree in its current state, and I spent hours trying to figure this out with no solution as of yet. I thought a decorator might help, but it just freezes at the sound location. Any help is appreciated!
Hey there, thanks for your kind words! There is an option called "Notify Observer", by default this is equal to "On Value Change", and if you have "Observer Aborts" set to "self or both", that means that this branch will get interrupted if the "VALUE" of the decorator changes. But.. if you change the "Notify Observer" to be equal to "On Result Change". This will interrupt the branch anytime the variable is changed, EVEN IF the value itself didn't change. That means that if the "State" is "investigating", and then something happens and updates the state to "investigating" again. The decorator will still abort. That might be what you want to do. Try it out and let know.
It should interrupt if you have the observer abort set to self or both and on result change instead of on value change. But if it's not working then you can try a different solution, which is to add a 2nd decorator that checks if the value of the investigation location has changed, and if so, it interrupts and starts over
Love the vid but I came into a problem near the end and everything was working fine but now when i make a noise and a enemy cannot see me it sends both the sight and the hearing senses through at the same time (know this because i printed text) anyone got an Idea why its doing this?
Hmm… not really sure what the problem is, but I recommend joining the Discord server and asking there, maybe someone encountered the same issue (link in the description)
Thank you for this beautiful course, but I have a question. I want to understand un5 your triangle completely in order to do that. How did you learn it with this understanding? Do you memorize the methods or invent them?
Glad you're enjoying it! When learning, I didn't try to memorize anything, I kept googling everytime I wanted to do something, and I found myself googling the same thing over and over again until I memorize it. But the best way to learn, is to have an idea in your head that you want to build and keep researching, watch a lot of videos, keep trying different things. Trial and error is your best friend. If you are not making mistakes, then you're not learning
Thanks for free knowledge. I have a little question. when I duplicate this enemy on my level, should they work the same? but i have only one enemy working properly. or does Behavior Tree Only Work for One AI Character Spawned? ed: "get all actors of class"
Hey there, the behavior tree is not a global object, meaning that for each instance of an enemy in your level, there is a separate instance of the behavior tree. So you can have as many enemies as you want and each will run their own copy of the tree.
Hi! I don't understand. what is the problem. My bot starts an investigation, but constantly moves towards the player, although its target point is the place of noise (location from the stimulus)
Hey there! If you have sight senses setup, then as soon as your enemy sees your player, it will switch from investigating to attacking. Make sure to check which state the enemy is in and debug the issue there
4:52 How do you reconfigure the number options in the AI debugger? I couldn't find any option to do that in editor preferences. My number pad doesn't work, so I currently have no way to access the different debugger menus. *Edit:* Nvm, I figured it out. It's actually called the Gameplay Debugger, not the AI debugger. You have to go to Project Settings > Gameplay Debugger, and all the binding options are there.
Hey! I'm glad you figured it out 😊. Yes, the Gameplay Debugger can be a bit tricky to find at first. Thanks for sharing your solution! It might help someone else in the future 🙏.
Ali, absolutely Amazing Tutorials and I love the pace you are running these and excellent content. Question, I created this blackboard on the base enemyBP and then created 2 child BPs, set their patrol route correctly, but only one of them actually utilizes the blackboard. the second one just stands still. any suggestions?
Hey there! Thank you for your kind words! Regarding your question, I'm not really sure what you mean by creating a blackboard on an enemy BP, blackboards are assigned to behavior trees only, and are accessed from an AI controller. So I'm not really sure what you mean :D
Its a nice tutorial but I have a problem that I cannot figure out. If I am behind the enemy and make a sound, the enemy already sees me without turning around. The enemy immediately changes into the combat state and chases me down. I know that he must be seeing me (without actually seeing me) because it doesnt happen if there is a wall between me and the enemy. The weird thing is that if I use the senses visualization, the enemy doesnt actually look at me but the sight sense is the one triggering the combat state.
Thank you 🙏 glad you liked it. It could be that your AI controller is turning and facing the player but your actual pawn is not. And the senses are placed on the AI controller not the pawn. If you go to your enemy pawn class and in the details panel check the box that says "Use controller desired rotation" then the pawn should use the same rotation the controller uses. (Note though, that if the pawn has a slow rotation speed, then this problem will still occur)
For some reason the senses dont work for me, it shows that it sensed in the debugger but it doesn't print any strings or response to sight senses at around 25:00
Hey there, Make sure that the issue isn't with printing itself, sometimes when using the AI debugger, it disables print screen messaging from appearing. So make sure that everything else is being printed
Hi! I have one question, how can i handle when the enemy lose sight of the player for an amount of time? Like, the enemy sees me and start chasing me, I enter in a building and he cannot longer see me, how can I tell at the AIController to (for example) start investigating the last seen location? Thank you for those tutorial btw, those saved my life more and more times
Hey there! I addressed this issue and explained that the functionality to make the AI "forget" the player and go back to patrolling or investigating the last seen location is added in Part 9 of the series. You need to implement a "forget actor" functionality for this behavior to work properly. You can check it out here czcams.com/video/U9WionHmfCM/video.html
Nice video, by the way ali, is it better to use 1 AI controller for all enemy? cause im thinking do i need to set up AI perception in each AI controller? or duplicate it? or each one should have a single separate AI controller? this goes for the behavior trees as well?
Thanks! Glad you liked it. Regarding your question, you can indeed create multiple AI controllers for different enemies, I actually do that at the end of the series, when I implement the boss, because the boss enemy has some unique perception and other things, so I create a child class of the base AI controller for the boss. Same with behavior trees, you’ll see that I create multiple behavior trees for each enemy type as the series progresses
Thank you for such detailed and consistent tutorials! In this video ForEachLoops nodes are used within some functions and events. Considering performance issues, does the ForEachLoop stop after the last array element is processed? Don't we need to set up loops breaking logic manually?
You're very welcome! I'm glad you're finding the tutorials useful. Yes, the ForEachLoop automatically stops after the last array element is processed, so you don't need to set up manual breaking logic. If you are looping over an extremely large array though (thousands of items) then I suggest using "For each with break" loop, which allows you to manually break from the loop once you have found what you're looking for in the array
Hello, thank you very much for your videos. I wanted to ask you how to make several enemies hear and see at the same time. Because I've only managed to get one to listen and the rest not. Obviously I don't need a complete answer, just something to know where to start investigating.
Hey! Thanks for your message, I really appreciate it 🙏 The default behavior is for multiple enemies to hear at the same time, you shouldn't need to do anything extra for that, if that's not working, there must be a bug somewhere
Thank you so much for the tutorial! informative & helpful! Yet I have a problem I don't know why my enemy ai doesn't switch state when hearing a sound/sight. It works when debugging tool, but it stucks in the passive state in patroling even I am within sight or make a noise. Would really appreciate some help!!
Hey there! Glad you found this helpful! Unfortunately I don't know what your exact problem is, but i suggest checking the conditions for switching states in the AI controller that they are being called as expected, and if so, then check the blackboard values and the decorator for switching states, that it is setup with the correct valuss
Hey Ali, Thank you for this amazing tutorial. I have question. When there is a small obstacle between the player and the AI, the AI Perception doesn't see the player and It's because the AI perception is locked on the center of the player character. Therefore, even if I'm standing up in behind a table, the AI can not see me. Do you know if there is a possibility to change where the AI perception targets the player please ?
Unfortunately with the default AI perception system, you can't change the location where the AI looks to. You'd have to build custom functionality for that or use a different plugin
I knew little about AI from UE before watching your videos; your videos are amazing. In this tutorial, I have a small bug, When the enemy attacks and I press the 'F' key to trigger 'Make Noise,' the AI stops chasing me and moves towards the direction of the sound. Where is the bug here?
Hey Emma, glad you’re finding these useful so far, happy to help. If your enemy goes from attacking to investigating, that means in you are allowing a transition from Attacking state to Investigating state, if you don’t want that to happen then make sure that you only allow transition from passive to investigating
Hi guys, just running through this again and noticed when he see's you and you get out of range, he just stops moving and the Behaviour Tree goes off it's Tree(hehe) swapping between wielding sword and trying to move to attack but it can't, so i added another sequence before the wield sword , it has 2 tasks, one task moving to the last sight stimulus location with a check sight decorator(checking if can see player), the 2nd task is just set state to passive, goodluck guys
So far so good. I was able to implement everything you said though part 1, 2, 3. Thank you very much for posting it here for free! One question. So i have a door in my game but even if its open, the ai does not go through it. I made sure that the NavMeshBound is covering it. Do you think it has to do with the collision of the door?
Hey there, this is a common issue with nav meshes because they don't update automatically when something changes, like a door opening or a box moving. To update the navmesh you have to setup the door to be a navmesh modifier. Checkout this tutorial that explains that well czcams.com/video/0AQzDuRtZnM/video.html

One of the best tutorials I've seen in UE5, even with my custom enemy with custom animation bps and player character I'm able to do everything correctly. Love this series!
Also "If the opponent is.. dead for example they shouldn't attack me" cracked me up a little:)
Thank you! I'm happy to hear that you found the tutorial helpful and that it worked with your customized setup. Glad you enjoyed the series, there are definitely some funny moments in there that weren't scripted 😂
All of your tutorial are amazing and your work is incredible.
Like in this video, for my game project i just need the sight, and no need for the rest, and it still work perfectly
Thank you so much for your kind words! I'm glad to hear it worked well for your project. If you have any questions or need further assistance, feel free to ask 🙏
@@AliElZoheiry Thanks a lot ! For the moment i'm working with another of your tutorial ! The one so the AI lost interest in me and go back to patrol
i don't understand why dude has 7k subs other channels can't do half of this dude does but they have around 50-80k subs with those funny open/close function BP's amazing man can't believe
Thank you for saying that. I appreciate the support, and hopefully I'll reach those 50-80k subs soon if people see the value of these videos ☺️🙏
@@AliElZoheiry i believe u will man your content's are amazing keep it up

4:26 For people having issues with their apostrophe key not showing up debug AI menu, it turns out that you have to change your keyboard settings on your computer's operating system. The keyboard on your OS needs to be set at US Standard. Anything else and Unreal most likely won't register it. Hope it helps.
And how to remap the keys of categories? There is no numpad here.
@@emmanuel.tavares If you're stil stuck on this, you'll have to go to Project Settings > Engine > Gameplay Debugger > Input and all those characters are there if you need to change them
thank you, not everyone one uses the same keyboards
@@emmanuel.tavares to change keybindings, you need to look into project settings, under gameplay debugging.

These keep getting better. Gonna follow the whole series and see where I end up. It would have been nice to have a reset timer on the attacking state once Line of Sight was broken for so long. I assume this can be done threw the behavior tree. gonna play around and find out before the next video!
Thank you for your comment! I'm glad you're finding the series helpful. and that behavior is covered in part 9 of the series ;)
By far you have the best UE tutorials!
Thank you so much Snafuey. I really appreciate your support
Thank you for the tutorials. You are explaining nicely. Easily understandable. Please continue this video series.
Thank you Sj! Really happy you found it useful and I will definitely continue the series, stay tuned ;)
Great series! I do have a suggestion though for anyone following the tutorial. There is already a function which pretty much does what is implemented with "Can Sense Actor". Its called "Get Currently Perceived Actors" and lets you choose a "Sense" to get actors for. This should be much faster than looping through the senses for each actor.
Glad you enjoyed it! And this system does indeed use the function "Get currently perceived actors"
Perefect!
Everything worked very smoothly without bugs ;D
And I even managed to implemented the preseption system to work with the previous created abilities from AOE and Projectiles tutorials ;D
Which shows me that I'm actually learning something and not bluntly following your steps. This for sure speaks for your teaching methods!
Cant wait to continue after dinner :)
cheers!
Hey, that's fantastic to hear! I'm thrilled to hear about your successes. It's great to know you're learning and adapting the knowledge. Enjoy your dinner and looking forward to hearing about your progress after! Cheers!

Thank you so much for saying that Raduvady, I really appreciate you. And I'm happy to hear that you're finding this content useful 🙏
This is by far the best tutorial on enemy AI , thank you so much, on every tutorial i have an issue where AI bump into each other when fallowing the player, i hope you can touch on that in this series, 🙏
Thanks alot Ashen! I briefly touched upon the subject of having many enemies in the level, and that for that use case you should probably use the "Detour Crowd AI Controller", but I will try to touch upon it nearing the end
this is what i need an in depth series on 1 certain thing not one 10 minute tutorial on how to do a simple behaviour tree then not knowing how to bug fix and solve issues along with expanding the tree
Really glad you liked it. I indeed try to go in depth and actually teach a subject, so that following my tutorials means you can create your own and not just copy and paste my code
@@AliElZoheiry exactly! I’m not using third person template And I have tried but I cannot figure out how to do Ai animations, the animation blueprint graph has to be set up differently to pawn and I can’t find anywhere how to fix it
as always such a fantastic tutorial, your channel is the shinning example of UE5 educational content,
Thank you so much for your comment. Your support means a lot to me 🙏
This is so complicated and yet you deliver the best lessons that can really teach someone. I've never created an AI before but with your tutorials I can understand the logic behind it and do something on my own. Thank you for such a great work! Also I wanted to ask about AI. So I want to AI to stop chasing/attacking me after I go out of sight radius, what's the best and optimal way to do this? To create another state when the enemy lose player and then create a Selector with condition in Attacking Sequence right before FocusTarget where I check if he's lost the player or not? Or maybe there's better and easier way to do that?
Hey! Thank you for your kind words, I'm really glad to hear that my tutorials are helping you understand AI better 🙏 For your question, I implemented that behavior in part 9 of this series czcams.com/video/U9WionHmfCM/video.html
@@AliElZoheiry thank you so much!!! I should have seen the other parts first... Anyway thank you. Followed everything!
Thank you for the tutorial. You are explaining nicely. Easily understandable.

Great Video as usual.
edit: Ok you'll cover this in a later video.
Enemy should return to passive state if he can't see the player anymore. Did you cover this behaviour in the video?
I guess we need to create another handle for that.
Yup, that was the "Forget target" behavior in part 9
Very nice AI tutorial, it helped me a lot ! thank you !
great tutorial, really helpful and very well explained! Keep going with the hard work and if you ever make a tutorial about local co-op with various gamepads on UE5 or online multiplayer using EOS on UE5 that would be really fun and interesting to watch!!
Thank you Gonçalo! Really happy you found it helpful. I'll definitely consider your suggestion, sounds interesting
@@AliElZoheiry I have been watching some of your videos and they are insanely helpful and insightful so I'm eager to see more!
I just realized that after this particular episode, I can start creating simple mobs for some hack'n'slash game :D
That's great to hear! I'm glad you found the episode helpful for your game project. Good luck with creating the mobs for your hack'n'slash game! 🎮
Your teaching is amazing, explains perfectly. thank you very much
You're very welcome 😇 and thank you for the support and kind words 🙏
Hey amazing tutorial and I can't wait to watch the rest of the series. I was wondering how to make the AI enemy to stop chasing and attacking the player once out of sight, returning his passive state. Please let me know if you know how this can be done
You're very welcome! Glad you're enjoying this.The behavior you want is covered in part #9 of this series
Loving this series! Fun fact: Real humans have a FOV of about 135 horizontal and 180 vertical :D
Glad you're enjoying the series! That's a cool fun fact about human vision 😄
Probably the highest quality tutorial I've ever seen. I love your vids!! One question tho, when I'm behind a wall and I make a sound, my AI is stuck in the Move To task and he just stands in place. I don't know why, same thing happens when damaging him from behind the wall I followed every single one of your steps and re-watched that part countless times
Hey there, thank you so much for your kind words and support! Not sure what the issue is, because the MoveTo shouldn't care about line of sight, as long as there is a path from the enemy to the player, the MoveTo should work correctly
@@AliElZoheiry I'm so dumb, it was a problem with the nav mesh not covering the area I was testing in... it's always those small things that mess me up haha. Thank you for your help man, I'll definitely keep watching your videos and you already have my sub!

Teacher your Perception tutorial are amazing. Even complicated config function, You explain it very clearly even newbie like me can understand what this function can do.
Also what is different about [Target] and [actor] in function Can Sense Actor mean, Isn't it the same that refer to self?
PS.I just finished half of the Part 3 on to the set up thing and I got a big question in my head when teacher mentioned about C++ , So in the real process in making the game do I need to learn C++ to improve this function? Or I need to learn coding to understand more complicated thing ,Please guide me to the right path .
Hey, thank you for your kind words and your questions. I'm glad to hear that you're finding the tutorials helpful. Regarding your question. "Self" doesn't refer to the actor, self always refer to the current class you're in, so in the AI controller, self is a reference to the AIC_EnemyBase controller.
Regarding C++, generally speaking, yes C++ will be required for working in actual company that uses Unreal Engine. Even though there as games built fully using Blueprints, C++ is required for performance optimization and low level systems building

Make sure you are the server when you fire Make Noise node, otherwise it will not work.
Also, if the print text does not work, instead restarting the engine, you can type EnableAllScreenMessages in the game console and you are good to go
Hey, thanks for the tips! I'll keep that in mind. Appreciate the help!
25:38 how does it know what blackboard you're referencing when you add the get blackboard reference node?
This variable is automatically set by the engine when you call "Run Behavior Tree" in the AIController, the engine then get's the blackboard that is associated to that behavior tree and set's that variable's value.
just finished thanks alot again!
Glad you found it helpful! See in the next one ;)
Thank you for your effort. I would like to know what is the way to detect not only the explosion sound but also when you run fast when it is nearby :)
You're welcome! To detect multiple sounds, you follow the same approach, just call the Make Noise function whenever you want to trigger a sound that the enemy Ai can hear
Hey Ali, every time the enemy senses anything, it stacks. For example, if it sees me and hears me at the same time, when it sees me again, it will think it hears me and sees me. I'm wondering if you could have any idea what is going on. Love your tutorials. Edit: I think it was solely a problem with the print strings, because it hasn't affected gameplay to my knowledge.
Hey there! Thanks for sharing your experience. It does seem like the issue might be related to the print strings. It's great to hear that it hasn't affected gameplay. Keep an eye on it, and let me know if you need any further assistance. Glad you're enjoying the tutorials!
Noice xD havent completed the ai but the other videos are easy to understand xD. Whats the next series about skill tree :D love that or maybe recreating game mechanics :)?
Ohh recreating game mechanics is an interesting one indeed
@@AliElZoheiry xD i can help u give a list of mechanics that ik arent available on yt right now
@@sara-uh8xy sure, that would be very helpful 🙏
If anyone is getting errors when testing if the AI will see or hear you and go after you that deals with the blackboard returning none - just add an "? is valid" node before whatever the blackboard is connected to and plug the blackboard variable in there and it will work. It just needs to check before running the loop.
Thank you for sharing this helpful tip with the community! It's always great to see different solutions to common issues.
You Will continué this saga of tutorials? Are interesting and very good explained🙌
Thank you Trebla, I will indeed continue this. Tomorrow (or maybe tonight) I will release Part 4 on the topic of EQS

Fantastic sir, god bless you.
Hey, thank you so much for your kind words! I'm really glad you found the content helpful. God bless you too! 🙏
In the "responding to sensing an actor" section why not just use the "On Target Perception Updated" node? I am still new to this, so I may be missing something, but it seems a lot easier that way. My understanding is that that node gives you a separate call for each time an actor is sensed, so you would not need to loop through an array each time.
Hey there, indeed it seems that it is easier to use, but at the time of making this video, I had some issues with "On Target anything.." I hope that by now they fixed those issues, but also using "On Perception Updated" isn't that much more complex, and gives us control over how to deal with each actor
The best, new patreon
Thank you so much! I really appreciate that 🙏❤️
Hi, how can I refine this system so that when the enemy chases me and I leave his line of sight, he loses me? I fixed all previous problems
Hey, you will find this implementation in part 10 of this series czcams.com/video/U9WionHmfCM/video.html
@@AliElZoheiry thats part 9 :P
Ahh yes, thank you, I meant part 9 indeed 👌
Love your tutorials! Hands down the best tutorials regarding enemy AI in CZcams. I have just one question. How do I allow interruptions in the investigating state? For example, let's say you make a sound and the enemy begins to approach the area of the sound. If you create another sound at another location, I want the enemy to stop their route to the 1st sound and make way to the 2nd sound. I can't do that with the behavior tree in its current state, and I spent hours trying to figure this out with no solution as of yet. I thought a decorator might help, but it just freezes at the sound location. Any help is appreciated!
Hey there, thanks for your kind words! There is an option called "Notify Observer", by default this is equal to "On Value Change", and if you have "Observer Aborts" set to "self or both", that means that this branch will get interrupted if the "VALUE" of the decorator changes. But.. if you change the "Notify Observer" to be equal to "On Result Change". This will interrupt the branch anytime the variable is changed, EVEN IF the value itself didn't change. That means that if the "State" is "investigating", and then something happens and updates the state to "investigating" again. The decorator will still abort. That might be what you want to do. Try it out and let know.
@AliElZoheiry I tried this and it doesn't work 😔 I tried it in both the beginning sequence of the investigating tree and under each of the tasks.
It should interrupt if you have the observer abort set to self or both and on result change instead of on value change.
But if it's not working then you can try a different solution, which is to add a 2nd decorator that checks if the value of the investigation location has changed, and if so, it interrupts and starts over
for some reason point of interest is saying invlid and it wont swith from attacking mode after it get into it what did i do wrong aha please help
Hey there, I suggest checking where you set that blackboard variable, maybe you are not calling it correctly, or passing an incorrect location.
Love the vid but I came into a problem near the end and everything was working fine but now when i make a noise and a enemy cannot see me it sends both the sight and the hearing senses through at the same time (know this because i printed text) anyone got an Idea why its doing this?
Hmm… not really sure what the problem is, but I recommend joining the Discord server and asking there, maybe someone encountered the same issue (link in the description)
Great, thank you
You're welcome! Happy to help 🙌
Thank you for this beautiful course, but I have a question. I want to understand un5 your triangle completely in order to do that. How did you learn it with this understanding? Do you memorize the methods or invent them?
Glad you're enjoying it!
When learning, I didn't try to memorize anything, I kept googling everytime I wanted to do something, and I found myself googling the same thing over and over again until I memorize it. But the best way to learn, is to have an idea in your head that you want to build and keep researching, watch a lot of videos, keep trying different things. Trial and error is your best friend. If you are not making mistakes, then you're not learning
Thank you. I will do the same. I hope you continue these great chains. Great work. “The Godfather of un5”@@AliElZoheiry
Thanks for free knowledge.
I have a little question. when I duplicate this enemy on my level, should they work the same? but i have only one enemy working properly. or does Behavior Tree Only Work for One AI Character Spawned?
ed: "get all actors of class"
Hey there, the behavior tree is not a global object, meaning that for each instance of an enemy in your level, there is a separate instance of the behavior tree. So you can have as many enemies as you want and each will run their own copy of the tree.
@@AliElZoheiry thank you👌👌 I think I made a mistake in my code
Hi! I don't understand. what is the problem. My bot starts an investigation, but constantly moves towards the player, although its target point is the place of noise (location from the stimulus)
Hey there! If you have sight senses setup, then as soon as your enemy sees your player, it will switch from investigating to attacking. Make sure to check which state the enemy is in and debug the issue there
4:52 How do you reconfigure the number options in the AI debugger? I couldn't find any option to do that in editor preferences. My number pad doesn't work, so I currently have no way to access the different debugger menus.
*Edit:* Nvm, I figured it out. It's actually called the Gameplay Debugger, not the AI debugger. You have to go to Project Settings > Gameplay Debugger, and all the binding options are there.
Hey! I'm glad you figured it out 😊. Yes, the Gameplay Debugger can be a bit tricky to find at first. Thanks for sharing your solution! It might help someone else in the future 🙏.
Ali, absolutely Amazing Tutorials and I love the pace you are running these and excellent content. Question, I created this blackboard on the base enemyBP and then created 2 child BPs, set their patrol route correctly, but only one of them actually utilizes the blackboard. the second one just stands still. any suggestions?
Hey there! Thank you for your kind words! Regarding your question, I'm not really sure what you mean by creating a blackboard on an enemy BP, blackboards are assigned to behavior trees only, and are accessed from an AI controller. So I'm not really sure what you mean :D
Keep up brother
Thank you for the encouragement! I appreciate your support 🙏
Its a nice tutorial but I have a problem that I cannot figure out. If I am behind the enemy and make a sound, the enemy already sees me without turning around. The enemy immediately changes into the combat state and chases me down. I know that he must be seeing me (without actually seeing me) because it doesnt happen if there is a wall between me and the enemy. The weird thing is that if I use the senses visualization, the enemy doesnt actually look at me but the sight sense is the one triggering the combat state.
Thank you 🙏 glad you liked it.
It could be that your AI controller is turning and facing the player but your actual pawn is not. And the senses are placed on the AI controller not the pawn. If you go to your enemy pawn class and in the details panel check the box that says "Use controller desired rotation" then the pawn should use the same rotation the controller uses. (Note though, that if the pawn has a slow rotation speed, then this problem will still occur)
For some reason the senses dont work for me, it shows that it sensed in the debugger but it doesn't print any strings or response to sight senses at around 25:00
Hey there, Make sure that the issue isn't with printing itself, sometimes when using the AI debugger, it disables print screen messaging from appearing. So make sure that everything else is being printed
Hi! I have one question, how can i handle when the enemy lose sight of the player for an amount of time? Like, the enemy sees me and start chasing me, I enter in a building and he cannot longer see me, how can I tell at the AIController to (for example) start investigating the last seen location? Thank you for those tutorial btw, those saved my life more and more times
Hey there! I addressed this issue and explained that the functionality to make the AI "forget" the player and go back to patrolling or investigating the last seen location is added in Part 9 of the series. You need to implement a "forget actor" functionality for this behavior to work properly. You can check it out here czcams.com/video/U9WionHmfCM/video.html
Hello Ali! After the AI loses eye contact with the player, the state does not change. The AI continues to follow&attack the player. How to fix it?
Hey there, this "forget" functionality is added in part 9 of this series
Nice video, by the way ali, is it better to use 1 AI controller for all enemy? cause im thinking do i need to set up AI perception in each AI controller? or duplicate it? or each one should have a single separate AI controller? this goes for the behavior trees as well?
Thanks! Glad you liked it. Regarding your question, you can indeed create multiple AI controllers for different enemies, I actually do that at the end of the series, when I implement the boss, because the boss enemy has some unique perception and other things, so I create a child class of the base AI controller for the boss. Same with behavior trees, you’ll see that I create multiple behavior trees for each enemy type as the series progresses
Thanks for clarifying that, i think i asked you this early without watching the rest of the videos, ill do so to understand better @@AliElZoheiry
Спасибо тебе за твою работу! Ты очень крутой! Твое учебное пособие по AI лучшее!
Thanks for watching and commenting ☺️🙏 really glad you found it useful
My report damage event doesn't work. Debug sphere doesn't shown when I press X button. I did same thing what you done
I solved. Someone who get an error like me just put the AI perception in the AI controller not BP_enemy
Yeah indeed the AI perception component is meant to be added only to AI controllers
Thank you for such detailed and consistent tutorials!
In this video ForEachLoops nodes are used within some functions and events. Considering performance issues, does the ForEachLoop stop after the last array element is processed? Don't we need to set up loops breaking logic manually?
You're very welcome! I'm glad you're finding the tutorials useful. Yes, the ForEachLoop automatically stops after the last array element is processed, so you don't need to set up manual breaking logic. If you are looping over an extremely large array though (thousands of items) then I suggest using "For each with break" loop, which allows you to manually break from the loop once you have found what you're looking for in the array
@@AliElZoheiry Thanks!
Hello, thank you very much for your videos.
I wanted to ask you how to make several enemies hear and see at the same time.
Because I've only managed to get one to listen and the rest not.
Obviously I don't need a complete answer, just something to know where to start investigating.
Hey! Thanks for your message, I really appreciate it 🙏
The default behavior is for multiple enemies to hear at the same time, you shouldn't need to do anything extra for that, if that's not working, there must be a bug somewhere
@@AliElZoheiry Thank you very much and I was able to detect the error.
You are the best.
Why can my enemy see me tru the wall ?
Maybe the wall doesn't block the visibility channel?
Thank you so much for the tutorial! informative & helpful! Yet I have a problem I don't know why my enemy ai doesn't switch state when hearing a sound/sight. It works when debugging tool, but it stucks in the passive state in patroling even I am within sight or make a noise. Would really appreciate some help!!
Hey there! Glad you found this helpful! Unfortunately I don't know what your exact problem is, but i suggest checking the conditions for switching states in the AI controller that they are being called as expected, and if so, then check the blackboard values and the decorator for switching states, that it is setup with the correct valuss
Hey Ali,
Thank you for this amazing tutorial. I have question. When there is a small obstacle between the player and the AI, the AI Perception doesn't see the player and It's because the AI perception is locked on the center of the player character. Therefore, even if I'm standing up in behind a table, the AI can not see me.
Do you know if there is a possibility to change where the AI perception targets the player please ?
Unfortunately with the default AI perception system, you can't change the location where the AI looks to. You'd have to build custom functionality for that or use a different plugin
I knew little about AI from UE before watching your videos; your videos are amazing.
In this tutorial, I have a small bug, When the enemy attacks and I press the 'F' key to trigger 'Make Noise,' the AI stops chasing me and moves towards the direction of the sound.
Where is the bug here?
Hey Emma, glad you’re finding these useful so far, happy to help.
If your enemy goes from attacking to investigating, that means in you are allowing a transition from Attacking state to Investigating state, if you don’t want that to happen then make sure that you only allow transition from passive to investigating
Hi guys, just running through this again and noticed when he see's you and you get out of range, he just stops moving and the Behaviour Tree goes off it's Tree(hehe) swapping between wielding sword and trying to move to attack but it can't, so i added another sequence before the wield sword , it has 2 tasks, one task moving to the last sight stimulus location with a check sight decorator(checking if can see player), the 2nd task is just set state to passive, goodluck guys
Hey! Thanks for sharing your solution! It’s always great to see how others tackle issues. Good luck with your implementation! 🙏
So far so good. I was able to implement everything you said though part 1, 2, 3. Thank you very much for posting it here for free! One question. So i have a door in my game but even if its open, the ai does not go through it. I made sure that the NavMeshBound is covering it. Do you think it has to do with the collision of the door?
Hey there, this is a common issue with nav meshes because they don't update automatically when something changes, like a door opening or a box moving. To update the navmesh you have to setup the door to be a navmesh modifier. Checkout this tutorial that explains that well czcams.com/video/0AQzDuRtZnM/video.html
