To get the direction of an object from the player:
_direction = ((getpos object select 0) - (getpos player select 0)) atan2 ((getpos object select 1) - (getpos player select 1));
_direction will be from -180 to 180
If positive values are needed then use:
if(_direction < 0) then {_direction = _direction + 360};
