Just an Idea to do it

I have 10 objects and want to do something if a collision happens between any of them and Box1. Box 1 can collide with other objects, but I do not want to do anything with that.
I have done that by writing if statement for all of them, but this way is really hard to accommodate
I have to write this

Code:

 if Box in viz.phys.intersectNode(Obj1) :

.

.

if Box in viz.phys.intersectNode(Obj10):

Anybody has an idea?
Thanks,
Moh

You can register a callback function for collision events. If each of these 10 objects has collide notify enabled:

Code:

.enable( viz.COLLIDE_NOTIFY )

then whenever a collision happens with one of those objects the function will get called. Then you can check to see if the second node passed with the event object is the box:

Code:

#Called when two objects collide in the physics simulator

def onCollide(e):

    #Did object collide with box?

    if e.obj2 == box1:

        #Do something

        

viz.callback( viz.COLLIDE_BEGIN_EVENT, onCollide )
