#
#Sometimes you'll want to create and position your own collision solids in

#done by adding special tags into an egg file. Check maze.egg and ball.egg
#and look for lines starting with <Collide>. The part is brackets tells
#Panda exactly what to do. Polyset means to use the polygons in that group
#as solids, while Sphere tells panda to make a collision sphere around them
#Keep means to keep the polygons in the group as visable geometry (good
#for the ball, not for the triggers), and descend means to make sure that

#have at least one bit in common. That way things that shouldn't interact
#won't. Normal model nodes have collision masks as well. By default they
#are set to bit 20. If you want to collide against actual visible polygons,
