Hello,
So i've recently made a derby system, works perfectly with 2 players but when there are 3 players it gets messy.
Here's the problem.
If there are 3 players playing, and if one of them falls off the other two wins the round, I've been trying to find the problem but i can't, Using height check at onplayerupdate.

PHP код:

public OnPlayerUpdate(playerid)
{
    if(DB_On == 1 && DB_Participants>1 && DB_Onhold == 0 && DB_Map==1)
    {
    new Float:x, Float:y, Float:z;
    GetPlayerPos(playerid, x, y, z);
    if(z < 2.1000)
    {
        Dcar(playerid);
        DB_Member[playerid]=0;
        DB_Participants--;
        Slap(playerid);
        SpawnPlayer(playerid);
    }
    }
    if(DB_On == 1 && DB_Participants==1 && DB_Onhold == 0)
    {
    if(DB_Member[playerid]==1)
    {
    Dcar(playerid);
    DerbyWin(playerid);
    }
    }
    return 1;
} 


Should i use a timer instead?
