ok ppl i fixed and solved it!!

i made it like

pawn Code:

new ongmx[MAX_PLAYERS]; //somwhere aboove
...

public OnPlayerDisconnect(playerid, reason)
{
...
    if (ongmx[playerid] != 1) {OnPlayerUpdate(playerid);}
...
}
...
public OnPlayerCommandText(playerid, cmdtext[])
{
    new cmd[256];
    cmd = strtok(cmdtext, idx);

    if(strcmp(cmd, "/gmx", true) == 0)
    {
      new countpl;
      for(new i = 0; i < MAX_PLAYERS; i++)
        {
           new Float:X, Float:Y, Float:Z;
           if(IsPlayerConnected(i))
           {
               GetPlayerPos(i, X, Y, Z)
               PlayerInfo[playerid][pPos_x] = X;
               PlayerInfo[playerid][pPos_y] = Y;
               PlayerInfo[playerid][pPos_z] = Z;
 
               OnPlayerUpdate(i);
               countpl += 1;
               ongmx[playerid] = 1;
             }
        }
        new givemsg[128];
        format(givemsg, sizeof(givemsg),"%i Users Updated", countpl)
        SendClientMessage(playerid,COLOR_BLUE, givemsg);
        
        SetTimer("GameModeExitFunc", 5000, 0);
        return 1;
