Collision Events

[PandaKid95]

Hi guys
Im having a little trouble with the collider. It says the collider is emptey and I don’t know how to fill it.

DirectStart: Starting the game.
Known pipe types:
wglGraphicsPipe
(all display modules loaded.)
Assertion failed: !collider.is_empty() && collider.node()->is_of_type(CollisionNode::get_class_type()) at line 111 of c:\p\p3d\panda3d-1.6.2\panda\src\collide\collisionTraverser.cxx
Traceback (most recent call last):
File “RoboVenture2.py”, line 231, in
w = World()
File “RoboVenture2.py”, line 115, in init
base.cTrav.addCollider(self.Robo, self.collHandEvent)
AssertionError: !collider.is_empty() && collider.node()->is_of_type(CollisionNode::get_class_type()) at line 111 of c:\p\p3d\panda3d-1.6.2\panda\src\collide\collisionTraverser.cxx

**** End of process output ****

Please Help
Thanks Guys

self.Robo is your collision solid(s) wrapped up in a CollisionNode, correct?

According to that error, self.Robo is either empty, or contains something other than a CollisionNode.

You should assign CollisionNodes (containing Collision solids) to the traverser.

Such as:

wallRay = CollisionRay (0, 0, 0.5, 0, 0, -1)
wallFinder =  object.attachNewNode (CollisionNode('wallFinderCollisionNode'))
wallFinder.node().addSolid(wallRay)
wallEvent = CollisionHandlerQueue()
base.cTrav.addCollider (wallFinder, wallEvent)
