this would be (in my mind) used if you were to make avertual reality game were the player were a sort of helmet or somthing of that nature which contained a screen so the players eyes never leaves the screen and a wirless keyboard/controler would be recomended if the player desides to do a 360 and look behind himself.

and now that i added my two cents just have to say i am really impressed you showed me something that i did not even know gamestudio was capible of congrats
