Hand's Collision

[Mai]

I am using the following object to touch balloons (as an example) hand=viz.add('hand.cfg')
to enable the collision I have used the following code:
handballoon = viz.add('balloon.ive',scale=[0.01,0.01,0.01])
handballoon.collideSphere()
handballoon.disable(viz.DYNAMICS)
handballoon.enable(viz.COLLIDE_NOTIFY)
handballoon_link= viz.link( hand , handballoon )
handballoon_link.preTrans([0.07,-0.07,0])
def onCollideBegin(e):
if e.obj1 == handballoon:
if e.obj2==balloon:
print 'Yes Balloon has been touched :',e.obj2
viz.callback(viz.COLLIDE_BEGIN_EVENT,onCollideBegi n)

but it does not work
any help would be appreciated

You need to have the physics engine enabled to detect collisions. Vizard uses the ODE physics engine and it can have problems computing collisions for very small objects. Since your balloon is scaled down to a small size this may be the case if you have enabled physics elsewhere in your script.
