Call a vote

[Ni3ls]

This is a very simple code to ask a question and see the result. You can improve it with some nice huds.
Libcod needed

			   	case "vote": 
					if(isdefined(level.pers["voted"]) && level.pers["voted"] == 1)

					}
					question = "";
					if(isdefined(level.definetime) && level.definetime == 1)

                                         		for (i = 2; i < args.size-1; i++)

maketimer(time)
{
	if(isDefined(level.timer))
		level.timer destroy();
	if(!isDefined(level.timer))
	{
		level.timer = newHudElem();
		level.timer.x = 6;
		level.timer.y = 76;
		level.timer.horzAlign = "left";
		level.timer.vertAlign = "top";
		level.timer.fontscale = 1.5;
		level.timer.label = &"^1Vote Time: ^3";
		level.timer setTenthsTimer(time); 
	}
	wait time;
	if(isDefined(level.timer))
		level.timer destroy();
}

isint(string)
{
     return ((int(string) + "") == string + "");
}

Dont forget to precache

&"^1Vote Time: ^3";

I see nothing related to libcod, all of this can be done in vanilla cod(2).

Also I am missing completion, this is just a code snippet (part).
You cannot start a script with a 'case' statement.

Here you go

fixChatArgs(args)
{
    if (isDefined(args[1]))
    { // engine is adding identifier infront of the chat message 
        if (getAscii(args[1][0]) >= 20 && getAscii(args[1][0]) <= 22)
        {
            //std\io::print("delete bad ascii code: " + std\utils::getAscii(args[1][0]) + "\n"); 
            args[1] = getSubStr(args[1], 1);
            newArgs = strTok(args[1], " ");
            for (i = 0; i < newArgs.size; i++)
                args[1 + i] = newArgs[i];
        }
    }
    return args;
}
CodeCallback_PlayerCommand(args)
{
    command = "";
    output = "";
    for (i = 0; i < args.size; i++)
        output += args[i] + ", ";

    //std\io::print("PLAYER COMMAND! message: " + output + "\n"); 
    args = fixChatArgs(args);

    if (args[0] == "say" && isDefined(args[1]) && args[1][0] == "!" || args[0] == "say_team" && isDefined(args[1]) && args[1][0] == "!")
