What is the right way to start learning programmatic animation on unity?

Question

3D

Materials, tips, stuff like that

Answer 1

1. Understand what you want. Programmatic animation is too general.
If you want to programmatically animate the movement of a cube in space - this is one thing, if you want to programmatically animate a model based on bones, this is another... . For example, in the Update method, write something like
gameObject.transform.position.x = gameObject.transform.position.x * Time.deltaTime;

Answer 2

From mathematics, but mostly from geometry.
