How to animate an object through code?

Question

Unity

I need to make an animation for an object so that the object moves along one axis (y). The fact is that I have several objects that should have animation (up, down) smoothly. When animating through Unity animation, all objects move to the same point. In short, I need to make sure that all objects move smoothly up and down at the same time and that they are in different places. How to do it?

Answer 1

DOTween asset:

float upY = 5f;
float time = 2f;
transform.DOMoveY(upY, time).SetLoops(-1, LoopType.Yoyo);

Answer 2

void Update() => transform.Translate(Vector3.up * Time.deltaTime * 0.001);
