my bullet is an area 2d node with it's own scene. It is being instanced in my main scene, which has a kinematic body 2d with a collision shape 2d that i want to detect the collision with. All the collision tutorials i see, have used areas and signals. The problem is, I'm not using an area (except in the bullet, which isn't the node i want to detect with,) and that the bullet is only instanced, so it's hard to connect the signal with it. How do i do this?
