Does A* support volumetric/voxel/6DOF pathfinding? I’m not sure if I’m asking the right thing exactly. Something like a spaceship or helicopter navigating a 3d space where in addition to left/right/forward/back, it can also ascend/descend.
Ideally it would also support normal ground-based pathfinding as well, so a game could have a mix of ground-based units as well as air-based units.
I could probably fake air units just with a separate navmesh and having the altitude handled by a script or something, but that seems like it could get messy, having to do separate altitude avoidance etc.
