Collision between two moving objects (Kinematic)?

A Collision in terms of physics consists of two things:

• collision detection (intersection detection)

• collision response (a physical reaction to the collision)

Kinematic rigidbodies are not physics objects because they can't receive a collision response as they are not driven by the physics system.

However kinematic rigidbodies can detect intersections with triggers. Triggers basically encapsulate only the intersection detection part. There's no information of "collision points", collision normals or the collision velocity. You only get the information when you enter a trigger, when you are inside a trigger and when you leave that trigger.

If you need more information about the collision you have to use non-kinematic rigidbodies.

In your specific case, what would you like to happen when you detect a collision? Since you move the objects "manually" they won't "collide" and somehow stop. This can only be achieved when using the physics system as this sort of "correction" can only be achieved when the system is allowed to correct the motion (collision response).

If you need further help, be more specific what exactly you want to happen.
