Intersect vs collision

[farshizzo]

In this case collision callbacks won't work, so you need to manually call the intersect function yourself.

Why? Will the collision callbacks work while dragging something with the HD? That's what I'm trying to do....

Yes, the callbacks will still work when you are dragging an object. Like I mentioned above, you will need to explicitly enable collision notifications on an object for a callback to be triggered.

I have enabled collision on everything but it still never registers the callback. I did this:

made a bunch of screws and said this for each one:

screw.collideCapsule()
screw.enable(viz.COLLIDE_NOTIFY)

I also made a box:

currentBox.collideMesh()					#make a collision mesh so we know when screws hit it
currentBox.enable(viz.COLLIDE_NOTIFY)

Then I did this:

def onCollide(e):
	print "collision!"
	global allM1Screws, allM2Screws
	#Did a screw hit the box?
	if ((e.obj2 in allM1Screws) or (e.obj2 in allM2Screws)):
		#Change color of box
		e.obj1.color( random.choice( [viz.RED,viz.GREEN,viz.SKYBLUE,viz.YELLOW,viz.ORANGE,viz.PURPLE] ) )

        
viz.callback( viz.COLLIDE_BEGIN_EVENT, onCollide )


viz.collision(viz.ON)

I never enter the collision callback code
