Please zoom-in the attached image :
1. On the EngineA Map Editor, I repositioned the player to (4,15).
    When I  ran the code, the player was facing the south wall.
    How to make him facing to the north room ?

2. What function should I write on the code editor so that I can display player's information :
    a. player's coordinates / position (x,y,z)
    b. player's angle (in degree/radian) so that I can turn him to face the north room. 

Thank you.
