Detecting Collisions

To detect when an object touches, or stops touching another, both GameObjects must have a collider component attached(box, sphere, etc), with the Is Trigger box unchecked on both of them.

For a component to detect triggers, it must be on the same GameObject as one of the collider components.

First inherit from Component, Component.ICollisionListener, then implement public void OnCollisionStart() or public void OnCollisionStop, public void is necessary. In the parenthesis, add Collision collision. This sets a variable "collision" to the collision event so you can use it in code.
