Where do you use OnMapStart function? Let me explain you. EvenTeams needs a player's id in order to work.

If OnMapStart uses a player's id, then you need to assign it to the timer. For example, it would be:

pawn Код:

SetTimerEx("RandomZombie",5000,false, "i", playerid); // an example

// somewhere else
public RandomZombie(playerid) return EvenTeams(playerid);

That would work, if OnMapStart uses player's ID.

On the other hand, if this function is in OnGameModeInit for example or somewhere else, you will need to use a random ID.

But..

if you don't want this line:

pawn Код:

ZombieSetup2(playerid);

Then it can be used like:

pawn Код:

stock EvenTeams()
{
    new Humans, Zombies, rand = random(2);
    if(rand == 0) // Setting ID 0 to Human and continuing with the cycle
    {
        foreach(Player, i)
        {
            if(Humans == Zombies)
            {
                HumanSetup2(i);
                Humans ++;
            }
        }
    }
    else // Setting ID 0 to Zombie and continuing with the cycle
    {
        foreach(Player, i)
        {
            if(Humans == Zombies)
            {
                ZombieSetup2(i);
                Zombies ++;
            }
            else
            {
                HumanSetup2(i);
                Humans ++;
            }
        }
    }
    return 1;
}

// Somewhere else
public RandomZombie() return EvenTeams();

It's up to you.
