I'm trying to detect collision between different objects that are not under the same parent but failed to achieve what I want.
here is a scene for Note. this scene is simply and image with an Area2D and a collision shape to detect collision.
this is the main scene with a lot of control nodes. But here two are particularly important.
The Note node which is of type RigidBody2D is supposed to slide down with a constant speed toward the bottom. This node doesn't need detection collision yet. it will contain multiple note scenes and make all this "note" slide down with the body.
there is also and Area2D with a collisionShape2D. this one is fixed and doesn't move.
My problem is that Notes are sliding down because they are parents to the RigidBody? but once they reach the bottom and should detect collision with the static Area2D nothing happened.
what should I do to make it work ? is nested collision impossible with godot? is detection collision incompatible with Control node?
