After trying exporting tag for Collide with Chicken from Blender, i putted the code copied from Roaming Ralph one,
Console shows me this:
Known pipe types: wglGraphicsPipe (all display modules loaded.) :collide(error): Invalid attempt to detect collision from CollisionRay into CollisionRay! This means that a CollisionRay object attempted to test for an intersection into a CollisionRay object. This intersection test has not yet been defined; it is possible the CollisionRay object is not intended to be collidable. Consider calling set_into_collide_mask(0) on the CollisionRay object, or set_from_collide_mask(0) on the CollisionRay object.
need to write something extra?
Maybe looks a bit clear, but not sure what thing is bad…
