What are the best features to use?

Question

C++ / C#

What is the difference between the functions and which one is better to use:
Collider.OnCollisionEnter(Collision)
Collider.OnTriggerEnter(Collider)
For example, I want one object to collide with another and the second one to fly in that direction. Tobish, if I collided with a cube with a cube on the right side, then it should fly in the direction of impact, that is, to the left.

Answer 1

For the task you described, none of these functions is needed at all - physics will automatically calculate new force vectors and everything will scatter automatically
