Need help with; Random selection from List of choices.

[Vectif 372]

Hello once again; I've come across another thing that I was wondering how could I do.
I'm working in a mission currently; and there's a loadout that you always spawn with, right? - I kind of don't like that I'm or the people playing would always spawn with the same uniform everytime they spawn/respawn; so I was trying to use "BIS_fnc_selectRandom" but I couldn't really understand how to apply it.

Here I'm using a loadout script (Kill_Phil's; https://forums.bistudio.com/topic/142113-respawn-with-custom-loadout/),although, everything works fine and all; but I wanted to know or get some help towards how to make this work making it choose a random uniform off of a list; and maybe same for Headgear.

here's the script;

loadout.sqf (All credit to Kill_Phil for the "template".)

waitUntil {!isNull player};      

 

_unit = _this select 0;

removeallweapons _unit;

removeallassigneditems _unit;

removeallcontainers _unit;

removeHeadgear _unit;

removeGoggles _unit;

 

_unit forceaddUniform "U_BG_Guerilla2_3";

_unit addmagazines ["12Rnd_mas_45acp_Mag", 1]; 

_unit addmagazines ["12Rnd_mas_45acp_Mag", 1]; 

_unit addweapon "hgun_mas_acp_F"; 

_unit addHandgunItem "acc_mas_flash_gun";

_unit addItem "Ace_CableTie";

_unit addItem "Ace_CableTie";

_unit addItem "Ace_CableTie";

_unit addItem "ACE_quikclot";

_unit addItem "ACE_elasticBandage";

_unit addItem "ACE_elasticBandage";

_unit addItem "ACE_morphine";

_unit addItem "ACE_epinephrine";

*/

 

if(true) exitWith{};

So as you may see, there's a highlighted command; that's the command that forces the uniform on the unit (since the units we're talking about are from a different faction.)
I'm struggling to figure out how could I extend this list, for example; ["U_BG_Guerrilla2_3","Xitem1","Xitem2"] and make it randomly choose one of these for the unit (*player*) that spawns/respawns.

Once again, thanks in advance.

Hi kyootlaer

 

Try this:

_uniforms = [ "U_BG_Guerrilla2_3","Xitem1","Xitem2"];
player forceAddUniform (_uniforms select  (floor (random (count _uniforms))));

Hi kyootlaer

 

Try this:

_uniforms = [ "U_BG_Guerrilla2_3","Xitem1","Xitem2"];
player forceAddUniform (_uniforms select  (floor (random (count _uniforms)))); 

 It's perfect  :) .

Thanks you very much.

This is what I used to use

 

   missions        = ["killcivmission","rescuemission", "capturemission];
    _missionToSpawn = missions call BIS_fnc_selectRandom;

 

It's a BIS function so should ... be faster

It's a BIS function so should ... be faster

This is the function:

if (count _this > 0) then {
    _this select (floor random (count _this));
} else {
    ["Array has no elements."] call bis_fnc_error;
    nil
};

So probably not any faster. :)

In fact, in some cases the BIS functions are unnecessarily complex so it may be more efficient to write your own for your specific situation.

So probably not any faster. :)

Idd prob not

Well, after some testing in multiplayer and etc, etc; It seems to work just fine. 
It seems to sometimes spawn players other than the host naked for some reason though.

On a side topic, which is still about selecting from random choices, how could I get this to work with vehicles being randomly selected from a list of choices?
