Random Array

[Kydoimos 916]

Hi all - just need a little help with picking a single part from an array - but randomly! I've played around with the random functions, but it seems everything I try sets off all parts of the array simultaneously.

_Array = ["_Grenade_Random_A", "_Grenade_Random_B", "_Grenade_Random_C", "_Grenade_Random_D", "_Grenade_Random_E", "_Grenade_Random_F", "_Grenade_Random_G", "_Grenade_Random_H", "_Grenade_Random_I"]

I just want to pick one of these to execute! Thanks - I'm sure the answer's quite obvious - I had a little search through the forums - forgive me if I've missed a thread that covers this in detail! :p

_Array = ["_Grenade_Random_A", "_Grenade_Random_B", "_Grenade_Random_C", "_Grenade_Random_D", "_Grenade_Random_E", "_Grenade_Random_F", "_Grenade_Random_G", "_Grenade_Random_H", "_Grenade_Random_I"];
_randomElement = _Array call BIS_fnc_selectRandom;

Thank cuel - I'll try that! :p

Still having problems! But I don't think it's your code, cuel - here's my full script:

private ["_Grenade_Random_A"];
_Grenade_Random_A = "Grenade" createVehicle getMarkerPos "Grenade_A";
private ["_Grenade_Random_B"];
_Grenade_Random_B = "Grenade" createVehicle getMarkerPos "Grenade_B";
private ["_Grenade_Random_C"];
_Grenade_Random_C = "Grenade" createVehicle getMarkerPos "Grenade_C";
private ["_Grenade_Random_D"];
_Grenade_Random_D = "Grenade" createVehicle getMarkerPos "Grenade_D";
private ["_Grenade_Random_E"];
_Grenade_Random_E = "Grenade" createVehicle getMarkerPos "Grenade_E";
private ["_Grenade_Random_F"];
_Grenade_Random_F = "Grenade" createVehicle getMarkerPos "Grenade_F";
private ["_Grenade_Random_G"];
_Grenade_Random_G = "Grenade" createVehicle getMarkerPos "Grenade_G";
private ["_Grenade_Random_H"];
_Grenade_Random_H = "Grenade" createVehicle getMarkerPos "Grenade_H";
private ["_Grenade_Random_I"];
_Grenade_Random_I = "Grenade" createVehicle getMarkerPos "Grenade_I";
_Array = ["_Grenade_Random_A", "_Grenade_Random_B", "_Grenade_Random_C", "_Grenade_Random_D", "_Grenade_Random_E", "_Grenade_Random_F", "_Grenade_Random_G", "_Grenade_Random_H", "_Grenade_Random_I"]; 
_Random = _Array select floor random count _Array;
Sleep 10;
Sleep Random 10;
if (alive Ambient_Firing_FailSafe_D) then {[] spawn Ambient_Firing_Grenades};

Basically, this is making all the grenades explode at the same time...

I've also tried _randomElement = _Array call BIS_fnc_selectRandom;

You are trying to explode a grenade on a random position picked from an array, isn't it?

Yeah! You got it!

[IndeedPete 1038]

Do you want something like this?

_posArr = ["marker1", "marker2", ..., "markerN"];
_pos = getMarkerPos (_posArr call BIS_fnc_selectRandom);
_grenade =  "Grenade" createVehicle _pos;

If you want to determine random positions in a certain area you might want to look into SHKPos. It's perfectly suited for a task like this and the author gave me his explicit permission to use it on MANW, so you could simply ask him to grant you the same rights.

Hey, man! Thanks! That looks like it would do the job! :cool:

@IndeedPete - you are a legend! That's the first and only dancing banana I've ever awarded. :)

[cuel 25]

Your old script was creating every grenade, putting them in an array and then just selecting a reference to one of the (already) created grenades (and then doing nothing) :)

[barbolani 198]

Yes. Instead of a random grenade script was a carpet bombing one... efective too :)

[IndeedPete 1038]

Always happy to help, no bananas needed. :D

Looking forward to the third part of your script rework, the second one was awesome so far, thanks again!
