{
    new szString[128], Float:Position[3], szName[MAX_PLAYER_NAME];
    GetPlayerName(playerid, szName, sizeof(szName));
    GetPlayerPos(playerid, Position[0], Position[1], Position[2]);
    format(szString, sizeof(szString), "~g~Admin ~w~%s started a war ~n~ You will be teleported in ~r~10 seconds!. ", szName);
    GameTextForAll(szString, 5000, 5 );

    return 1;
}

forward TeleportPlayers(playerid, Float:X, Float:Y, Float:Z);
public TeleportPlayers(playerid, Float:X, Float:Y, Float:Z)
{
    for(new i = 0; i < MAX_PLAYERS; i++) SetPlayerPos(i, X, Y, Z);
