Passing arguments to params in switch/exitwith

[Robustcolor 30]

Hi, how can i pass different arguments to params in the same switch/exitiwith fnc?

 

Examples what i'm trying to do

 

[_patrol] spawn fnc_switch;

[_hunt] spawn fnc_switch;

fnc_switch = 
{

Params ["???"];

call {
	if (_patrol) exitWith
	{
		//code 1
	};
	if (_hunt) exitWith
	{
		//code 2
	};
	if (_garrison) exitWith
	{
		//code 3
	};
	//default will be _patrol
};
};

What datatype (number, string, ...) are _patrol/_hunt/_garrison?

The thing is i just want to pass an argument to the fnc so it activates one of the if exitwith or cases when one of the condition/name is same as the passed argument.

Yes I know but that depends on what data type the params are. The information is not enough to work with for me. If it is a string/number/object then comparing these is no problem but it gets harder with code/arrays.

fnc_switch = {
	//params[ [ "_mode", "PATROL", [ "" ] ] ];
	
	params[
		//First var
		[
			"_mode",	//variable name
			"PATROL",	//default value
			[ "" ]		//Must be of type STRING
		]
	];
	
	switch ( toUpper _mode ) do {
		case "PATROL" : {
			//Do something
		};
		case "HUNT" : {
			//Do something
		};
	};
};

[ "PATROL" ] spawn fnc_switch;

Thank you @Larrow

 

I'm combining it like this, might be a more efficient way of doing it. Since i want to have one function that spawns ai but still be able to call different scripts for the different Ai groups.

 

private _m1 = ["GUARD",5,_markerpos,_range] spawn VUnits;

private _m2 = ["HUNT",5,_markerpos,_range] spawn VUnits;

 

VUnits = {

params [["_mode","GUARD",[""]],"_g","_markerpos","_range"];

for "_i" from 1 to _g do

{
private _group = createGroup [east, true];

private _pos = [_markerpos, 0, _range, 5, 0, 0.4, 0, [],_markerpos] call BIS_fnc_findSafePos;

private _unit = _group createUnit [selectRandom Unitpatrol, _pos, [], 0, "NONE"];

sleep 1;

};

switch (toUpper _mode) do {
case "GUARD" : {
private _Guardscript = [_group,_markerpos] spawn Robust_fnc_Guard;
};
case "HUNT" : {
private _Attackscript = [_group,_markerpos] spawn Robust_fnc_Attack;
};
};
};

Since a switch is kinda slow, is it possible to convert it into this

call { 
if (PATROL) exitWith {
//code 1 
};
if (GUARD) exitWith { 
//code 2 
};
if (GARRISON) exitWith {
//code 3 
};
//default code 
};

I also changed toUpper command into toUpperANSI since it could be 3x faster than toUpper.

Not exactly:

params[ [ "_mode", "PATROL", [ "" ] ] ];

call {

  if (_mode == "PATROL") exitWith { //code 1 };

  if (_mode == "GUARD") exitWith { //code 2 };

  if (_mode == "GARRISON") exitWith { //code 3 };

  //default code

};

 

using   ==    rather than   isEqualTo     avoids a check for case sensitivity and you will not notice a great difference for code optimization.

 

NB: when you write if (PATROL)... the engine is waiting for ?  ?     ??

Spoiler

a boolean (i.e. TRUE or FALSE)

So, you could avoid such error, just reading at the BIKI syntax for EVERY command (at least when you begin).

Thanks @pierremgi

Ye i can't say it was any noticeably different from the switch when testing it.

 

Using it with isEqualTo.

params[ [ "_mode", "PATROL", [ "" ] ] ];

call {
  if (_mode isEqualTo "PATROL") exitWith { //code 1 };
  if (_mode isEqualTo "GUARD") exitWith { //code 2 };
  if (_mode isEqualTo "GARRISON") exitWith { //code 3 };
  //default code
};
