Does anyone have experience with collisionray in Panda3D?
I have setup a coillisionray and a queue to handle the events, but when I print out the coillisions from the queue something is wrong.
I assume that a ray is straight line but I sometimes get three of more collisions with objects that are not in line in any way!
Collision rays are pretty straight. 
But sometimes you can run into issues similar to yours if there is a scale transform between your ‘into’ and ‘from’ collision nodes. Also, there used to be an issue with starting the collision traversal on a node with any transform on it, but I believe that particular issue has since been resolved.
Can you post a code snippet illustrating how you’ve set up your collision system?
You could, of course, also take a look at the Roaming Ralph tutorial in the panda3d samples directory.
