Pre-defining Vehicle Variables (IF statement issues)

[UltimateBawb 1]

I've been making a mission with dynamic AI and vehicle spawning and have been having a problem with the creation of vehicles in IF statements. I'm aware that local variables created in IF statements do not apply for the rest of the block and would normally pre-define say an integer or string variable at the top of the block, but how can I do this with a vehicle variable? The code I currently have is:

	//Decides which vehicle to place based on multipliers and probability
	_prob = floor(random 100) * defendingMultiplier;
	if (_prob <= 20) then {
		_heli = createVehicle ["O_Heli_Attack_02_F", _targetMarkerA, [], 0, "NONE"];
		["Resources", 0.1] execVM "personalityHandler.sqf";
		} else {
		_heli = createVehicle ["O_Heli_Light_02_F", _targetMarkerA, [], 0, "NONE"];
		["Resources", 0.05] execVM "personalityHandler.sqf";
	};
	_heliGroup addVehicle _heli;

This results in errors when attempting to use _heli later.

_varName are local variables and will be cleared after the code hids an ending bracket ( }; ).

In this case you should add the private statement to declare a variable before the brackets.

private "_heli";
if (_prob <= 20) then {
		_heli = createVehicle ["O_Heli_Attack_02_F", _targetMarkerA, [], 0, "NONE"];
		["Resources", 0.1] execVM "personalityHandler.sqf";
		} else {
		_heli = createVehicle ["O_Heli_Light_02_F", _targetMarkerA, [], 0, "NONE"];
		["Resources", 0.05] execVM "personalityHandler.sqf";
	};
	_heliGroup addVehicle _heli;

Assuming this is the entire script, you'd do something like

	
private["_prob", "_heli"];

//Decides which vehicle to place based on multipliers and probability
_prob = floor(random 100) * defendingMultiplier;
if (_prob <= 20) then {
   _heli = createVehicle ["O_Heli_Attack_02_F", _targetMarkerA, [], 0, "NONE"];
   ["Resources", 0.1] execVM "personalityHandler.sqf";
} else {
   _heli = createVehicle ["O_Heli_Light_02_F", _targetMarkerA, [], 0, "NONE"];
   ["Resources", 0.05] execVM "personalityHandler.sqf";
};
_heliGroup addVehicle _heli;

Never repeat code. :)

//Decides which vehicle to place based on multipliers and probability
	_prob = floor(random 100) * defendingMultiplier;

        	_selectedType = if (_prob <= 20) then [{["O_Heli_Attack_02_F", 0.1]}, {["O_Heli_Light_02_F", 0.05]}];

        	["Resources", _selectedType select 1] execVM "personalityHandler.sqf";	
	_heli = createVehicle [_selectedType select 0, _targetMarkerA, [], 0, "NONE"];
	_heliGroup addVehicle _heli;

Ah, Kylania, that's a great idea! Also, thanks Mind and Sniper for showing how to define variables.
