Normal Direction

[das attorney 857]

Hi,

Add this to your list of functions. I never found a function that could normalise a direction into 0-360 properly so I wrote one and here it is in case you need to use a direction that may be out of 0-360 range.

horde_fnc_normalDirection = {
/*author: Das Attorney*/
private ["_dir"];
/*date: 17/08/2014*/
_dir = _this;
call {
	if (_dir > 360) exitWith {
		_dir = _dir % 360;
	};
	if (_dir < 0) exitWith {
		_dir = _dir % 360;
		if (_dir < 0) then {
			_dir = _dir + 360;
		};
	};
};
if (_dir in [0,360]) then {
	_dir = 0;
};
_dir
};

Here is some inputs and outputs:

INPUT: -800
OUTPUT: 280

INPUT: -723
OUTPUT: 357

INPUT: -720
OUTPUT: 0

INPUT: -540
OUTPUT: 180

INPUT: -360
OUTPUT: 0

INPUT: -167
OUTPUT: 193

INPUT: -0
OUTPUT: 0

INPUT: 37
OUTPUT: 37

INPUT: 367
OUTPUT: 7

INPUT: 720
OUTPUT: 0

INPUT: 800
OUTPUT: 80

Usage:

_return  = 800 call horde_fnc_normalDirection;
_return  = 720 call horde_fnc_normalDirection;
_return  = 360 call horde_fnc_normalDirection;
_return  = -0 call horde_fnc_normalDirection;

Is this going to be used in your new 'AllRoundDefence' for Arma 3? Hint!

Ha ha maybe, got some fish to fry first though!

New shorter version thanks to Larrow :)

fnc_dir = { 
   private ["_dir"]; 
   _dir = _this; 
   _dir = _dir % 360; 
   if (_dir < 0 ) then { 
       _dir = _dir + 360 
   }; 
   abs _dir 
};
