add force for a bumper car

im making a simple shove each other off the Cliff game how do go about making a scrips that adds force pules on enter collision

A good place to start would be to check out Rigidbody physics.

That is part of a series on physics. with rigidbodies you can add force, manage collisions, add colliders, and all sorts of useful stuff!

This should help you :slight_smile:
void OnCollisionEnter(Collision collision)
collision.collider.GetComponent().AddForce(new Vector3(your force), ForceMode.Impulse);
