How to return an error message? - grand.Theft.Otto - 04.12.2010

I have a /stadium command at the moment that teleport's to 17 different DM spots, but when someone types /stadium alone, I want it to return an error saying:

pawn Код:

USAGE: /stadium [1-17]

How can I do that?

This is what I have at the moment:

pawn Код:

if(!strcmp(cmdtext,"/stadium 17",true))
    {
        SetPlayerPos(playerid,593.0692,-2433.1682,46.8059);
        SendClientMessage(playerid,0x33CCFFAA,"WELCOME - Teleported To Deathmatch Stadium 17.");
        new string[128];
        new playername[MAX_PLAYER_NAME]; GetPlayerName(playerid,playername,sizeof(playername));
        format(string, sizeof(string),"%s (%d) Has Teleported To Stadium 17. (/stadium 17)",playername,playerid); SendClientMessageToAll(COLOR_PINK,string);
        return 1;

Thanks

You don't have to return a function call, you can also do like this (example from the upper code)

pawn Код:

if(!strlen(tmp))
{
    //some format function
    SendClientMessage(playerid,COLOR_RED,"USAGE: /stadium [1-17]");
    return 1;
}
