Fix bug induced by previous commit (player orientation wasn't stored correctly), and fix NPC not beeing able to move with certain angles (like angle Z 70) because the trace function was hitting NPC own hitboxes. The solution prposed here is a little hacky, but i works. Need a little clean up(mBody shouldn't be public)
