Love the idea of using an animation curve directly in a unity script!! That’s such a cool way to implement more natural or organic motion, rather than snappy linearly motion :)
This is probably one of the most precise yet comprehensive explanations I have seen of using Lerp in Unity. Subscribed and hope you continue making more
Just wanna reiterate to keep doing what you're doing - CZcams has a bunch of amazing early Unity dev tutorials but your videos exploring some of the more advanced/different ways to do things (async/await) and nice deep dives on topics (this video with lerp and animation curves) are very very helpful to fill in gaps for us intermediate Unity devs.
Found your channel recently and have been binge watching a bunch. I would say you are legit like having a brackeys 2.0 (But with your own style and flare). I consider myself a solid intermediate level game dev and I find myself learning a bunch from you. Please keep up the good work!
This is the one. This is the video that earned you a sub. A bit late, but I've only just discovered your channel. This is incredibly useful. Well done! Cheers!
@@Tarodev This has completely changed the way I move my cameras and other various objects. I could always use DOTween to do this, as well, but I really like having control using code, rather than relying on a third party asset. Using an animation curve is just icing on the cake ;-)
I've seen a lot of tutorials that use Lerp when MoveTowards would be better (e.g. constantly updating the start value of the Lerp) but I've never seen the two combined like this, and with a curve to boot! Simple, effective, and really handy. Nice one!
You have no Idea how much I am grateful for this simple video. I think it's been 2 days since I've tried doing a simple Slerp animation and just couldn't figure out why it would either skip to the end position, not move at all or just zoom across the game screen never to be seen again. Thank you so so much.
I got introduced to lerp yesterday and this video has been really helpful to see more use cases and to help me understand a little more the concept, thanks a lot as always!
I have never seen a better tutorial on lerp. I used to avoid it. But now knowing about blending that with animation curve. That is so sick. Thank you for this amazing tutorial man. Keep creating ❤️💯
Thank you so much! I am a new game dev/programmer and trying to make to make some enemy gameObjects move smoothly but everything else would kind of start being buggy once in a while. Lerp made everything easy. Thanks! =)
7:17 I literally didnt see the text until your video pointed towards it. Fortunately, I was already subbed ;P Looks like your tutorials are very attentive, damn.
incredible possibilities to those who master it. I am almost done with my first track, but there is so much more to discover and learn. TNice tutorials
OMG, dude, this is fucking awesome. I've watched this video yesterday briefly. Today I was trying the whole working day to add a tint to an image. And only at the very end I've understood that I need to MIX fucking colors! And I can do it with lerp! Actually, video is very pleasing to the eye and content is very useful as well! Have a good day!
There are two different lerp implementations (at least). Your way at 1:36 and my way. Just a different way of expressing the same algebraic formula: a) is your way, b) is my way. a) point = (a * (1-t)) + (b * t) b) point = ((b - a)*t) + a My way has only one multiplication operation - that means cheaper right?
@Cladaës Yeah, fair. I have never seen a) before so it stood out to me. I think of it in terms of delta*factor + start (i.e. b) but yeah, a) has some charm to it.
Hey, the formula is not very intuitive to me, so I did some equation manipulations and it seems way more intuitive to imagine the formula like this: a + t(b - a) Which can be interpretated as [The minimum value is 'a', added to the portion 't' of the difference between 'a' and 'b'] = a + t(b - a) = a + tb - ta = a - ta + tb = a * 1 - a * t + t * b = a * (1 - t) + t * b => Equivalent But the formula [(1 - t) * a + t * b] seems unclear and pretty 'complicated' compared to [a + t(b - a)] in my opinion but it can be just a preference :) Thanks for your video tho, and in general your tutorials and script are so advanced and optimized it's awesome, you're great!
Great video on lerping, wish I had seen this when it came out. But I learned about the AnimationCurve thing today, never seen it as a variable like that, its usually attached to a component. Thanks !!
Great stuff! Learned a lot, always have trouble with rotating stuff over time. This makes it soo much easier. Have you ever had any issues with this running constantly in update? I guess just putting the lerp in a separate function and put a check in update saying "if (current != target) Lerp(); would save on some garbage when the lerp is done doing its thing :)
my knowledge, understanding and ability to implement lerp is ephemeral and I literally need to relearn it every day. I can copy and paste a lerp function I wrote yesterday, apply it in a different scene, and it will not work or not work as intended. anyway, I really like your vids, solid content all around, im just incapable when it comes to lerp.
man I know it's been two months but I'm glad I'm not the only one. For whatever reason getting these to stick is impossible. Feels like there's some sort of underlying mathematical understanding or something about lerp that I just don't have. Frustrating.
Already knew about lerping however i never used AnimationCurve, instead i would spend hours trying to build mathematical functions that fits my needs. It's gonna be such a big help in my programming process damn
Great video! I really enjoy your content and a good Segway point if you were to work your way to a Bezier Curve tutorial. I'd love to see your take on a pattern or 2 (dealers choice of course on which) just love learning new things or new ways to achieve the things I may already know. Cheers!
@@Tarodev some patterns are more common then others, first one that comes to mind if the component pattern which unity uses extensively but the observer pattern is very useful in certain games. Here I uploaded a video that I think is a decent idea of maybe how an RTS game could use this pattern, check it out if you like updated it just for this reply haha. Observer Pattern attempt by me czcams.com/video/pLm1_HOdiXk/video.html
@@Tarodev yes, sorry I was in the middle of a meeting when I did that and the app I used has low graphic quality as I am not setup to do recording atm. Love the content, as well as the quality within!
Works well linearly (eg between floats or vectors) but won’t work properly for things line points in a sphere or a curved surface, or colour. In theory you can parametrise any N-D space to be linearised into a VectorN space, but using a dedicated Lerp method is usually cleaner
Should work for color. For curved surfaces there must be some adaptor function to convert linear t value to point on surface. Here is another video about lerp czcams.com/video/WNoizdtEPA4/video.html. Also t can be altered for smoothing effect t*t - quadratic, t*t*t - cubic etc.
hey i came across your channel recently ...can you make a beginner unity and c# 2021 tutorial ??your videos are awesome and are very good quality...can you make some beginner tutorials pls???a playlist also
Woah. I just watched few of your awesome videos. These were awesome! I should say twice XD. I assume that you are a JS dev and got into C# Unity just like me. And I use VSCode in JS area. And in unity VS seems like a good choice. But VS and VSCode are so different. And VS just triggers me a lot XD. And it looks like you already solved that hassle. So can you please make a video for VSCode vs VS or even Unity for JS devs? It would be finger licking awesome.
Ultimately, Rider is your best bet for c#, but short of that you absolutely want to go for Studio over Code. Code is fantastic for a lot of things, but IMO it falls short for c#.
I've spotted the problem with Evaluate function with the curve. It works only in one way with my code. For e.x. if you start slowly and end fast, then when you go backwards you begin with fast and end slowly. Any tips to solve this?
No need to use Update use IEnumerator) If you have already decided to do animation in the code better to use DOTween at all, it will be faster at least in terms of implementation
@@Tarodev Well, if the animation involves a fairly frequent change of parameters, then there may be problems with DOTweens and you will have to complicate the code) But in this comment I talked more about this animation that in the video) Sorry for my English)
They're closely related. Think of lerping as the concept of moving between 2 points (objects, numbers, vectors, colors, etc) and tweening as the style you do it. Dotween handles both for you obviously.
the formula at the start is super confusing at explaining what is going on in it. I looked at it thinking i knew what was going on, ended up not knowing what was going on. It would have been nice knowing what the formula did, and i think that's what you wanted to show by showing it. My reccomendation is to go over it and explain it as simple as you can. we take the percentage of the value we want to get to, plus the percentage of how much we are going to keep of the original value. I had c# give me a visualization of this start 5, end 10, time 0.5 1-0.5: 0.5, 0.5*5: 2.5, 10*0.5: 5, 2.5+5: 7.5
I reaaally didn't want to focus too hard on the maths and scare newcomers away. I wanted to quickly brush past it for the people who enjoy that aspect and get to the 'fun' stuff. So it's good you've explained it more in depth here to help people grasp it. Appreciate it!
You could do something like: this.gameObject.GetComponent().velocity = Mathf.Lerp(rb.velocity, targetVelocity, Time.deltaTime * Acceleration); This gives a way to implement “smoothed” acceleration. Note that the scaler ‘Acceleration’ usually needs to be very high, else your mover will fee somewhat floaty. Unless that’s what you want
Lerp is so fascinating, it blew my mind when I finally understood how fading between colours is also Lerp under the hood.
or bezier curves!
You can do so much with lerp! Plus it's super handy in shaders for (as you said) colors, gradients, etc.

= a * (1 - t) + t * b
=> Equivalent

I want to move one object to another using lerp is that possible😢
Cool video, helped me better understand lerp. How would you combine it with character controller Move()?
If you use Move(direction * _speed * Time.DeltaTime), it will give you movement. Is that what you're after?
You could do something like:
this.gameObject.GetComponent().velocity = Mathf.Lerp(rb.velocity, targetVelocity, Time.deltaTime * Acceleration);
This gives a way to implement “smoothed” acceleration.
Note that the scaler ‘Acceleration’ usually needs to be very high, else your mover will fee somewhat floaty. Unless that’s what you want
Nice Tutorial!
This is EXACTLY what you'd use lerp for. Any kind of movement (not physics based) can be done using lerp. You'll find you use it everywhere :)
