How to detect collisions between RigidBody2D and KinematicBody2D

+1 vote

I have a ball instance that is a RigidBody2D and I want it to 'activate' a button. This button is a KinematicBody2D. I don't think that the button should be a KinematicBody2D, but what do I know.

Any help would be greatly appreciated!

Can the button move? What does it do after it's been activated?

RigidBody2D can report collisions (contact monitor need to be enabled and set to more than zero) and you can get them via signal (body_enter) or checking on fixed process/custom integrator (get_colliding_bodies).

Then just just do something like getting the group of the object is touching (you can check the angle and other things to detect a correct trigger collision), if you identify it as a "button", tell that button to do something.
