Collision

[Moh200jo]

Hi, This code is trying to not allow the avatar to walk through the court’s wall and balloon.
May my collision statement for avatar is wrong, but this what I have found in tutorials.

import viz

viz.go()
viz.phys.enable()
court= viz.add( 'court.ive' )
court.setPosition(0,0,15)
viz.collision()
balloon=viz.add('balloon.ive')
balloon.setScale(7,7,7)
balloon.setPosition(0,0,8)
avatar=viz.add('vcc_female.cfg')
walk_Forward = vizact.walkTo([0,0,20])
avatar.addAction(walk_Forward) 
avatar.collideBox(viz.COLLIDE_NOTIFY)
avatar.disable(viz.DYNAMICS)

Any suggestion would be appreciated.
Thanks,
