Pushing a RigidBody2D with a KinematicBody2D

I want this kinematicbody (left) to push this rigidbody (right) and make it roll.

To make it roll i presume I’d have to use add_force() or apply_impulse(). But I can’t figure out how to detect collision. The best I could come up with is this:

enter code hereextends RigidBody2D
func _ready():
func _process(delta):
if $KinematicBody2D.get_position() == position:

But that’s really shitty code, hope it gets the point across.

(I’ve also been trying it other ways with get_slide_count() or get_slide collision(), but the $KinematicBody2D on the code returns null, although it is on the same scene, I’m trying to figure that out too.)

If you have code that moves the kinematic body, that should be enough: kinematic and rigid bodies always apply forces to rigid bodies they collide with.

As for why get_slide_count returns null, you might need to enable contact monitoring on the kinematic body and set the contacts reported to a number greater than zero. I’m not sure about that though, I’m not very familiar with messing around with slide info from kinematic bodies.
