Collision with avatars and scene not working

[JvdBosch]

This seems to work, I'll try backing up a few steps and recreate this code in my model.
I added male.disable(viz.DYNAMICS), because else the avatar looks very blurry (drawing error or so?)
AlsoI added gravity and a mousedriven walkto to see how it works.
I'll try to incorporate it into my model tomorrow.

But if anyone has anymore bright ideas how to detect collision with low cpu usage, please share!

Here's the changed code:

import viz

viz.go()
viz.MainView.setPosition( 0, 2, -5 )
viz.phys.enable()
viz.phys.setGravity(0,-10,0)
viz.setMouseOverride()

ground = viz.add( 'tut_ground.wrl' )
ground.collidePlane()

logo = viz.add('logo.wrl')
logo.collideMesh()
logo.disable( viz.DYNAMICS )

ball = viz.add('ball.wrl')
g=ball.collideSphere()

male = viz.add( 'male.cfg' )
male.translate( 0, 1, 4 )
male.collideBox()
male.disable(viz.DYNAMICS)

male.addAction( vizact.walkto( 0, 0, 0 ) )
male.enable( viz.COLLIDE_NOTIFY )

def onCollide(e):
	if e.obj2 == logo:
		print 'logo collide'
	elif e.obj2 == ground:
		print 'ground collide'
	elif e.obj2 == ball:
		print 'ball collide'

viz.callback( viz.COLLIDE_BEGIN_EVENT, onCollide )

def onmousedown(button):
  if button == viz.MOUSEBUTTON_LEFT:
    info = viz.pick(1)
    if info.valid and info.object == ground:
      walk = vizact.walkto(info.point[0],0,info.point[2])
      male.runAction(walk)
	
viz.callback(viz.MOUSEDOWN_EVENT,onmousedown)
