Try it with foreach, like this

pawn Код:

CMD:respawnallvehicles(playerid, params[])
{
    new string[128], name[MAX_PLAYER_NAME];
    if(APlayerData[playerid][PlayerLevel] < 3) return SendClientMessage(playerid, 0xFF0000FF, "Error : You don't have the required level to execute this command");
    
    GetPlayerName(playerid, name, sizeof(name));
    
    foreach(Player, a)
    {
        if(!IsPlayerInAnyVehicle(a))
        {
            for(new i = 0; i != MAX_VEHICLES; i++)
            {
                SetVehicleToRespawn(i);
            }
        }
    }
    format(string, sizeof(string), "Admin %s[%d] respawned all unoccupied vehicles.", name, playerid);
    SendClientMessageToAll(0xFFFF00FF, string);
    return true;
}
