Example 2:

Get direction from _obj1 to _obj2:_vd = getPosASL _obj2 vectorDiff getPosASL _obj1; _dir = (_vd select 0) atan2 (_vd select 1); //_dir range from -180 to +180 if (_dir < 0) then {_dir = 360 + _dir}; //_dir range from 0 to 360

Example 3:

Get relative direction from _obj1 to _obj2:_xy = _obj1 worldToModel getPosASL _obj2; _dir = (_xy select 0) atan2 (_xy select 1); //_dir range from -180 to +180 if (_dir < 0) then {_dir = 360 + _dir}; //_dir range from 0 to 360

To get the direction of an object from the player: _dir = ((getPos _obj select 0) - (getPos player select 0)) atan2 ((getPos _obj select 1) - (getPos player select 1)); //_dir will be from -180 to 180. If positive values are needed then use: if (_dir < 0) then {_dir = _dir + 360}; Or just use BIS_fnc_dirTo directly.
