Overshoot for scale function

Hello! I'm looking for a way to replicate the overshoot effect shown in this video

My intention is to have a player game object increase in size using this effect as he grows larger.

I've Googled around and the recommendation is to use a Lerp or SmoothDamp function to replicate the effect. I've watched some Youtube videos that cover both functions, but the interpolation the authors use always seem to be a smooth transition from one point to another. I've yet to see an example that gives me that "bounce" effect. Is there something I'm missing? would anyone be able to provide me with examples on how to achieve this?

Thanks in advance!

 

overshoot generally uses quadratic curves (which is not the same as linear), you will likely need a good tween library or write your own.
the other option is to use the in built animator and set it to a curve.

here is a good write up on tweens: https://kodi.wiki/view/Tweeners

 

Thanks for the insight! I'm looking at some different tween libraries now. At least there's no shortage of them.

 

Check out these easings. https://easings.net/en

You can just use

public AnimationCurve easing

and make whatever shape you want, then use Evaluate between 0-1.

Example:

Code (csharp):

1. public AnimationCurve curve;
2. float speed = 1f;
3. float anim;
4.  
5. void Update()
6. {
7.     anim += speed * Time.deltaTime;
8.     transform.localScale *= curve.Evaluate(anim);
9.  
10.     if (anim > 1f) anim = 0;
11. }
