I am using navigation mesh (triangulated) together with Bullet. In navigation mesh, I find path using A*. This gives me set of "points" inside triangles from navigation mesh. From those points, I create bezier, catmull or other interpolant.
The problem is, how to actually "move" NPC
My ideas:
1) I calculate new position via "dt" and forward vector (or local coordinate system) via derivation in a new point. This gives me correct NPC orientation and rotation, but it kinds of "break" other logic, because I "teleport" NPC from position to position (I have constant update rate, but still... if there is some small / thin Bullet collision body, it may goes through)
2) Use similar approach as for player. Methods like "MoveForward", "MoveLeft", "RotateAroundUp" etc. However, in this case, I am not really sure, how to calculate order of operations from interpolant. I have a current and final position (and orientation) and I need to get serie of "move" and "rotate" operations to get to that final position.
3) something else?
What is preferred solution? And how to potentioanlly do 2). I have beem looking over net, but found different ways, how to do this based on 1) or 2), but none of them was quite descriptive.
