If somebody else had made it maybe. I'm a lecturer, and as such will never use 5 words when 127 is possible ;P Thanks.

Like for instance, when you walk over that plane, music plays. When you walk over it again, it stops playing.

Good call. I do this kind of thing a lot, although I don't have a consistent policy of when I do and don't. There is a small danger with this, which is that it can lead to null reference errors if either you forget to populate the variable, or if you put the population in BeginPlay, it is dependent on the order of things being created to populate correctly. Another alternative is to use a macro or function.

I'm glad you find them useful. My aim, always is to explain to the best of my understanding what is happening, rather than just give steps to an end result, and to keep them short(ish). I am a lecturer, so naturally I revel in the sound of my own voice, so short is always a challenge.

glad you approve :)

I'm glad :)

Been asked this a few times now so... czcams.com/video/FVmpg_TJ_o0/video.html

Thanks. I'm not a dev, I'm a Uni lecturer. I don't have a studio, or any published games... yet (working on it). I do teach other aspects of game dev, and design is one of my areas. Check out my light blue videos on my channel for game design topics.

@@dansgamedevchannel6297 Ok plus noticed the accent my UK bud

@@lavaughnblanding3968 Aye. Born and bred.

Welcome :)

Welcome. What kind of music tech do you do?

I'm afraid that this is actually almost two separate questions. You would have to do the gravity yourself, and you would need to find the vector between the object and the planet. I have some videos on vectors on the channel, and am currently updating them to 5.4 although nothing has actually changed. You then need to apply a force along that vector. The strength should be according to an inverse square of the distance. I'm the kind of geek that knows the formula : F = G(m1 x m2)/Rsquared: m1 and m2 are the masses of the two objects, Rsquared is the square of the distance between them, and G is the "universal gravitational constant" which is (6.6743 ± 0.00015) × 10−11 m3 kg−1 s−2. DON'T PANIC if that is scary, because what your really need to know is, as you get further away the pull needs to be less, and you tweak that until it "feels" right. Depending on your circumstances, a constant pull might work. This gives you gravity in the right direction. The other part of this is that gravity doesn't guarantee that something hits the planet. Thank goodness, or we would be constantly being bombarded my meteorites. If they start by not moving relative the planet, then yes they will hit it. Give it enough sideways motion and it will orbit instead, or spiral out, or spiral in, or... strange things.

@@dansgamedevchannel6297 thank you very much

Hmm, there is a reasonable chance it is to do with things called "redirectors". Try this: In the content panel, right-click on the "content" folder and choose "fix up redirectors" (in 5.4 the name has changed, but it still has the word redirectors in, I forget what). This might take a while. After that, try again. I have an updated version of this video here: czcams.com/video/hWtMMjIxvG4/video.html Failing that, you may genuinely have something somewhere with is referring to one or more of the assets in the pack. There are more laborious ways of finding that by taking each asset in turn, right-clicking and finding references, and deleting when there are no references. You would start at the highest level of dependency - things like characters first, then meshes, then materials then textures, for example.

@@dansgamedevchannel6297 Thank you for taking the time to reply. Its a strange error which I have never came across before (and to be honest was driving me crazy). I gave your suggestion a go but was still encountering the same issue. In the end I had to create a new blank project then copy over (not migrate) the parts of the project I wanted to keep and all was well again. I am using 5.4 so maybe the issue could be an unresolved glitch, who knows. Its sure created a headache.

@@DJDCRYPTER Unfortunately I have had the same before, a project where something seems to be corrupted, and the only solution seems to be to start again. It may be that if I knew more I would be able to fix these things, but Unreal is huge, and it genuinely does seem to sometimes just fall over. Glad you were able to retrieve stuff.

Thanks :)

Thanks. Any thoughts I have here are mere speculation, and I may, in the future get a chance to ask somebody at Epic about this. These redirectors don't seem to be talked about much, but they can cause some unexpected issues if you are not aware of them. My best guess is that it is to do with version control. I believe you can also get redirectors in play if you rename assets. 5.4 is the first time I have seen anything in the engine that gives you information when you resolve them, and it talks about version control. Other thoughts that I have are that it could improve speed of moving stuff about, may be more robust over networks, may protect against engine crashes in the middle of file movement, may better support "undo", and/or may have been a temporary fix for some issue that got left in and made more permanent.

Sorry. Too shrill?

I'm glad :) thanks for commenting

I'm sorry, I cannot tell you, because it is something I don't know. Never tried to do that.

@@dansgamedevchannel6297 Its ok, it seems no one knows. I am watching a tutorial right now for local 2 player multiplayer, maybe I can find a way to reverse engineer it to achieve this.

@@srawdawg6188 I don't know if this will help you: forums.unrealengine.com/t/multiple-controllers-one-game/59132/6

Watch from about 5:50 onwards I show exactly that

You're welcome :)

I'm sorry, I don't have any videos about animation, it is an area of Unreal that I have never dealt with. Anybody else out there able to help?

@@dansgamedevchannel6297 its funny cuz they all try to hide this simple thig for idk what reason . i just need to put two characters in one window for editing animation so i can pos them frame by frame on each other clearly. maybe its a big companies secret .lol. btw thank you

@@julianneEVdmca it's not exactly what you're looking for, but when I need to edit the animation of two interacting characters I add them to a sequence on an empty level, bake the animation into the Control Rig and adjust it from there. Hope it helps!

I know it's sad, but at least you recognise my genius :)

I've never been somebody's goat before, but I choose to think it must be good. <Bleat>

@@dansgamedevchannel6297 My Guru if you whant X) but thanks you for all this channel is a real gold mine

Almost certainly, depending on your specific circumstances. I usually create widgets at the start of a level using Event Begin Play in the level blueprint. You need to create the widget and then attach it to the viewport. You probably then want to set its visibility to hidden and only display it when your death happens. The tricky bit might be displaying it in response to the death. If you have a more complex system, and you want to use the same triggering mechanism to trigger the death screen in different levels... say for example you have a game manager class, or you are controlling this from a GameInstance, then you might find it helps to have a variable in that of type UserWidiget (which can be populated by any UserWidget). Let's call it DeathScreen - seems like a good name. I'll quickly walk through this is GameInstance. You can do the following in the EventBeginPlay of the level: 1. Create a Widget of the type you want 2. Attach it to the viewport 3. Set it to hidden 4. Use the GetGameInstance node to get the game instance 5. Cast it to your actual GameInstance class 6. Set the DeathScreen variable to be this particular Widget Then, when the player dies, however that happens, wherever that is known (in the PlayerCharacter maybe) do the GetGameInstance thing again, and get the DeathScreeen, and change its visibility to visible. The beauty of this kind of approach is that you specify which death screen you are going to use in the level blueprint. This makes it easily different in different levels. Hope that helped

@@dansgamedevchannel6297 It did help a lot!! Thank you very much for the super complet answer sir ! I hope you'll have a nice day ^^

Thanks :)

Welcome :)

Sorry, I have no clue about that.

This is just off the top of my head, rather than trying it, but "Spawn Actor at Location" should allow you spawn an instance of any actor blueprint, and if it's a pawn type you should then be able to possess it with the player controller.

Thanks :)

The only thing I can think of is if you are running DigitalWorks from inside a zipped folder. You need to extract before it will run properly. If you already have, sorry, no other ideas.

Thanks for your thoughts. Can you explain why you say this? I understood Epic were trying to phase out timelines in favour of Level Sequences, and I have found Rotating Movement components somewhat inflexible.

You are welcome. Epic are huge, sometimes the right hand not only doesn't know what the left is doing, but is only vaguely aware of its existence. They are moving too fast to be able to keep up with themselves, and they are a bit like the keystone cops with people falling off and having to run to keep up. Otherwise, of course, Unreal is awesome.

Could you make a video describing Cast To, Blueprint Interface, and Event dispatcher and appropriate usage.

My advice is to avoid blueprints as much as possible. It totally breaks the usual programming paradigms and simple things like passing variables between objects is just total agony. You shouldn't need to be casting to 300 different types or firing events just to share the player's health with the thinger. Use blueprint and the Viewport etc. to set the basics up, but try to avoid after that.
