Hey all,
Im trying to create a collisionSegment between my player’s NodePath and my camera. I was looking through the api documentation about collisionSegments and their defined by the (x,y,z) of 2 points a and b. so i have the following code
def initCameraCollisions(self):
#self.cnodePath = base.camera.attachNewNode(CollisionNode('CollisionSphereCamera'))
#self.csphere = CollisionSphere(0, 0, 0, 4)
#self.cnodePath.node().addSolid(self.csphere)
#self.cnodePath.node().setFromCollideMask(BitMask32.bit(1))
#self.cnodePath.node().setIntoCollideMask(BitMask32.allOff())
#base.cTrav.addCollider(self.cnodePath, self.hitBoxCollEvent)
#self.accept('into-' + 'CollisionSphereCamera', self.cameraCollision)
self.rayNode = self.playerNP.attachNewNode(CollisionNode('rayCollide'))
self.cSegment = CollisionSegment(self.playerNP.getX(), self.playerNP.getY(), self.playerNP.getZ(), base.camera.getX(), base.camera.getY(), base.camera.getZ())
self.rayNode.node().addSolid(self.cSegment)
base.cTrav.addCollider(self.rayNode, self.rayCollEvent)
self.accept('rayCollide-into', self.cameraCollision)
def cameraCollision(self, collEntry):
#base.camera.setY(base.camera.getY() + 1)
#base.camera.setZ(base.camera.getZ() - 1)
base.camera.setPos(collEntry.getSurfacePoint(render))
print("camera Collided")but that yeilds an error of

Execution Successful!I didnt see antything about the name of the collision Segment in the api docs so i didnt know how to get the string of the collision event of the segment so i tried adding it as a solid to a collisionNode that does have a name. Is that the issue? Could i maybe get some form of an example of collision segments? Also if my player and camera are moving will i have to update the pos of point a and b of the collisionSegment to reflect that? Sorry lots of questions
