Lerping Fundamentals - Learn How to Use It & When to Use Its Variants | Unity Tutorial

Lerping is one of the foundational things you need to know about in video game development! There are so many use cases for lerping it's impossible to name them all! Almost any time you want to rotate, move, or change a value over time, lerping is an option.

Another common use for lerp is a smooth follow script, where the object moves towards its target and automatically slows down as it gets closer. This is done in an update timer constantly every frame, plugging its own position in for a, with a fixed t (which can be increased or decreased to adjust the speed).

[@LlamAcademy]

Very true!

[@djpersonalspace2406]

Brilliant tutorial. Thanks so much for this!

[@thepolygonpilgrimage]

Nicely done sir! Really enjoyed this. Some great, clear examples!

how can i use it for fixed speed vector3.lerp???

Thanks , amazing tuto ,
Can you please make a tuto for :smooth swipe movement (left _right ) like runner games of casual games ?
Thank you again ❤

[@LlamAcademy]

I'll add it to the list of topics to cover!

[@LTMidnight]

How would you go about making an object go from one point to another, but speed up as it gets closer to its destination?

[@LlamAcademy]

I would do this with an AnimationCurve. In the future more advanced lerping tutorial I'm planning I'll cover that in more depth. But essentially you can define a
[SerializeField]
private AnimationCurve LerpCurve;
and instead of passing time directly into the lerp, you can use LerpCurve.Evaluate(time);

[@Zify.z]

How do you lerp the cube between the two circle continuously for lerp with time?

[@LlamAcademy]

you can have a MonoBehaviour that lerps from one to the other and track which one it should be going to

[@macleodgordon]

I know how to Lerp, but I need to know how do I Lerp from A to B, then from B to C? Where do I put this code and do I need a coroutine to do this?

[@LlamAcademy]

If you want a 3 point lerp from A-> B -> C the easiest way to handle that is a coroutine (or update loop) just lerping exactly like you said, wait until you hit point b, then update to go to point C using B as the starting point for the second starting point and resetting your timer variable!

[@RDD87z]

any idea how could i rotate an object with an overshoot? something like a elastic (springeffect)?

[@LlamAcademy]

I have a video on springs here: ua-cam.com/video/6mR7NSsi91Y/v-deo.html

@@LlamAcademy nice. thank you

It's very important for my to understand how to make shooting system for my game.

[@unique_ideas091]

The file in GitHub is all pink as I import it in unity

[@LlamAcademy]

🤔 are you using HDRP or URP? This repository was using Built-In Render Pipeline. That's just a guess

[@newsystem3667]

One thing I would have liked to see is lerping a scale

[@LlamAcademy]

Scale works the same as position, since it is a Vector3. You can use the exact same code, but assigning to transform.localScale property instead of transform.position property

[@EricBalcon]

good tutorial but without complete scripts it's difficult for new learners like me.
