Pathfinder helper.

Hi everyone. I would like to do a cool pathfinder that founds a 3D reachable path by a player, jumping, crouching, and whatever. I know there is an a* module, but it needs “points”, so the hardest thing is to determine if a point is really reachable or not. So, if someone want to work with me to do a pathfinder, is welcomed.

PD: I said to help, that means I want someone to do PART of pathfinder, not entire.
PD2: Sorry for spelling mistakes.
