CollisionTraverser - Wound me up to much!!!

General Discussion
#1

I’ve tried to sort this out on my own and looking through the forum, but its wound me up to much!

basically i have collision nodes set up and what to add a transver node to the main character (ralph)

    
def setupCollisions(self):

      	# use an event collision handler (sends events on collisions)
	self.cHandler = CollisionHandlerEvent()
	# set the pattern for the event sent on collision
	# "enter" plus the name of the object collided into
	self.cHandler.setInPattern("ate-%in")
	# make a traverser and make it the default traverser
	self.cTrav = CollisionTraverser()
	base.cTrav = self.cTrav


	# add a sphere around Ralph to collide with the lollipops
	# get the bounding sphere of Ralph
	bounds = self.Ralph.getChild(0).getBounds()
	center = bounds.getCenter()
	radius = bounds.getRadius()
	cSphere = CollisionSphere(center,radius)
	cNode = CollisionNode("Ralph")
	cNode.addSolid(cSphere)
	cNode.setIntoCollideMask(BitMask32.allOff())
        cNodePath = self.Ralph.attachNewNode(cNode)



        # add Ralphs's collision node to the traverser as a collider


        self.cTrav.addCollider(cNode,self.cHandler)



	# traverser = CollisionTraverser('Ralph')
	# base.cTrav = traverser
	# traverser.addCollider(fromObject, handler)


	# add sphere around the lollipops to be collided into
	for target in self.targets:
		cSphere = CollisionSphere(Point3(0,0,15),15)
		cNode = CollisionNode("lollipop")
		cNode.addSolid(cSphere)
		cNodePath = target.attachNewNode(cNode)

        # end setupCollisions

And when i run it i get this error:

Warning: DirectNotify: category 'Interval' already exists
DirectStart: Starting the game.

    self.cTrav.addCollider(cNode,self.cHandler)

Press any key to continue . . .

Any ideas??

i’ve looked through the manual and the forum and tried some of the suggestions but still can’t get it working.

Please Help!

Change the line

        self.cTrav.addCollider(cNode,self.cHandler)

to

        self.cTrav.addCollider(cNodePath,self.cHandler)

Super thats done the trick… bout the only thing i didn’t try!

1000 Thanks
