Randomly Select Unit in Trigger

[Charles Darwin 10]

Ok so trying to randomly select a player unit inside a trigger and execute a small bit of code.

in the init:

[] execVM "spy.sqf";

spy.sqf:

if (isserver) then{
_triglist = list triggerone;
_count = count _triglist;
_num = round(random _count);
_spy = _triglist select _num;
};
hint format["%1 is a spy!", _spy];
_spy setvehiclevarName "spy";

code to be executed:

if("spy" == vehiclevarName player)then{bugaction = CO addAction ["Bug Commander", "bug.sqf"]; ["You are the Spy!"] spawn BIS_fnc_infoText; sleep 7;["Plant the GPS Bug","on your Commander!"] spawn BIS_fnc_infoText;};
_index = spy addMPEventHandler ["mprespawn", {bugaction = CO addAction ["Bug Commander", "bug.sqf"];}]; 

but it doesnt seem to find anyone in the trigger area as it always says null or any is spy

What are the settings of the trigger?

once

name: triggerone

Have you checked to see what's in _triglist ?

If _triglist is any then try initializing it before the if statement with _triglist = [];

Here's what you can use to pick one unitrandomly from an array:

_spy = *array containing players* call BIS_fnc_selectRandom;

Make sure you have a Functions module.

triglist should be any opfor unit in triggerone, thats the problem

tried that said it didnt work for objects

[kylania 568]

Works just fine for objects.

Place Functions module. Put down 3 BLUFOR units. Named them p1, p2 and p3. Put down a BLUFOR PRESENT ONCE trigger with this as onAct:

spy = thisList call BIS_fnc_selectRandom; hint format["The Spy is: %1", spy];

Each time I start up the mission I get a random Spy object.

My bad. Disregard this post..

Try this....

In the triggers init...

[s]nul = [thislist] execVM "spy.sqf";[/s]

...and for spy.sqf....

[s]if (isserver) then	{
_triglist = _this;
_count = count _triglist;
_num = floor (random _count);
_spy = _triglist select _num;
};

hint format["%1 is a spy!", _spy];

_spy setvehiclevarName "spy";[/s]

Tested and working fine. Oops! Not working.

ah i wasnt naming them before that could be problem..is there way to get the player's name..ie not the variable name but the player's profile name when the unit has a variable name?

Id like to west team to know which enemy team member is the spy so right now it says

"p1 is a spy!"

id like it to say "Charles Darwin is a spy!"

[kylania 568]

Works without naming them, but then you get "The Spy is B 1-1-A:3" or something. To give the player name just use name spy at the end instead of just spy.
