Panda3d Collisions made simple

Hi,

I eagerly went over the tutorial. Very well written. It helped me get a much better grasp of the Panda collision system.
After reading the 10 steps, I’m still having problems finding the right approach for the specific game I’m trying to write (a 2.5d platformer - the characters are 2d, and the platforms are 3d boxes).
Any suggestions as how to approach the collisions in such a game (I’m especially having a hard time figuring how to handle the “floors” - It seems I’ll need to know the collision direction (for stopping/starting a fall and so forth)).

Thanks,
Ogga
