Variable not defined when using local variable

[SSgt 'Ice Cold' Sykes 1]

Hi,

 

I'm trying to set up a minefield module via script.

I get an error when using local variables while everything works fine with global variables.

If anyone could tell why that'd be great.

Here's my code :

POP_fnc_Minefield =
{
	if ((typename _this != "ARRAY") or (count _this < 3)) exitWith {hint format ["Error : POP_fnc_Minefield argument : %1", _this];};

	_MineGroup  = createGroup [(_this select 0), true];
	_pos = _this select 1;
	_FieldSize = _this select 2;
	
	if (count _this <= 3) then {_NbMines = floor(_FieldSize/2);} else {_NbMines = floor(_FieldSize/2*(_this select 3));};	
	if (count _this <= 4) then {_MineType = "APERSMine";} else {_MineType = this select 4;};
	if (count _this <= 5) then {_FieldCond = TRUE;} else {_FieldCond = _this select 5;};
	
	_Minefield = "Site_Minefield" createUnit 
	[
		_pos,
		_MineGroup,
		format
		[
			"this setVariable ['minescount', '%1'];
			this setVariable ['minestype', '%2'];
			this setVariable ['axisa', '%3'];
			this setVariable ['axisb', '%3'];
			this setVariable ['shape', 'Rectangle'];
			this setVariable ['side', 'Independent'];
			this setVariable ['marked', 'Friendlies'];
			this setVariable ['conditionofpresence', '%4'];",
			_NbMines,
			_MineType,
			_FieldSize,
			_FieldCond
		]
	];
};

 

This code throws undefined variable errors but if replace _NbMines, _MineType, _FieldCond with NbMines, MineType, FieldCond then everything seems to work fine.

One thing I noticed is that the version of createUnit you are using does not return object. Wiki states this

[davidoss 552]

POP_fnc_Minefield =
{
	
	params [
		["_side","Independent",[""]],
		["_pos",[],[[]]],
		["_FieldSize",0,[0]],
		//optional below
		["_NbMines",floor ((_this select 2)/2),[0]],
		["_MineType","APERSMine",[""]],
		["_FieldCond",true,[true]]
	];
	if ( !(_pos isEqualType []) || (count _pos) < 2 || isnil {_this select 2}) exitWith {hint format ["Error : POP_fnc_Minefield argument : %1", _this]};
	private _MineGroup  = createGroup [call compile _side, true];
	private _Minefield = _MineGroup createUnit ["Site_Minefield", _pos, [], 0, "CAN_COLLIDE"];
	{_Minefield setVariable _x} forEach [
		["minesCount",format ["%1",_NbMines]],
		["minesType", _MineType],
		["axisA", format ["%1",_FieldSize]],
		["axisB", format ["%1",_FieldSize]],
		["shape", "Rectangle"],
		["marked", "Friendlies"],
		["side",_side],
		["conditionofpresence", format ["%1",_FieldCond]]
	];
	
(_Minefield)
};

_minefield = ["Independent",position player,100] call POP_fnc_Minefield

};

_minefield = ["Independent",position player,100] call POP_fnc_Minefield

So this has been working just fine for me until now because it seems it isn't possible to create more than one minefield. The unit gets created but there are no mines and i can't find the source of the problem.
