# A target that can be hit by gpu particles. the ProxyCollisionDetector

# does the actual detection. Expects a MeshInstance3d child as a visual
|
|
# and an AudioStreamPlayer3d to vary the volume based on the number of
|
|
# particles hitting it. As well as a CollisionShape3d for the collision

# this is kind of silly, but I'd like to use the actual CollisionShape3d
|
|
# node for the collision shape since it has an editor gizmo thing already built.
|
|
# this doesn't really interact with the real cpu physics engine though.
