// this, once the unit recieves its path, we use the same logic as in the pathfinding script to check to see if the SECOND point in the path is walkable from the unit's current position.
// If it is, we can skip the first node in the path. If it isn't, then the backtracking behavior is acceptable, and in fact, ideal.

// the current position of the nav point. If it is, skip it.
