pawn Код:

CMD:ooc(playerid,params[])
{
    new nu[128],string[128],pname[MAX_PLAYER_NAME];
    if(sscanf(params,"s",nu)) SendClientMessage(playerid,0xFF0000FF,"Use: /o(oc) [Text]");
    else
    {
        GetPlayerName(playerid,pname,sizeof(pname));
        format(string,sizeof(string),"((%s: %s))",pname,nu);
        SendClientMessageToAll(0xFC6103FF,string);
    }
    
    return 1;
}

For some reason,the messages can't be long. Their size is like half of the chat lenght,why is that?

Try This

pawn Код:

CMD:ooc(playerid,params[])
{
    new
        string[128]
        pname[24]
     ;
    GetPlayerName(playerid,pname,sizeof(pname));
    //
    if(isnull(params)) SendClientMessage(playerid, 0xFF0000FF, "Use: /o(oc) [Text]");
    //
    format(string,sizeof(string),"((%s: %s))",pname,params);
    SendClientMessageToAll(-1,string);
    return 1;
}

[dusk]

can you tell me more about "isnull"?

[PaulDinam]

isnull = if the player hasn't written anything.

[dusk]

so how is it different from sscanf

[Patrick]

so your not sure about isnull i made you a sscanf one try this

pawn Код:

CMD:ooc(playerid,params[])
{
    new
        string[128],
        pname[24],
        message[128]
     ;
    GetPlayerName(playerid,pname,sizeof(pname));
    //
    if(sscanf(params, "s[128]",message)) return SendClientMessage(playerid, 0xFF0000FF, "Use: /o(oc) [Text]");
    //
    format(string,sizeof(string),"((%s: %s))",pname,message);
    SendClientMessageToAll(-1,string);
    return 1;
}

PS: i just re check your command you forgot to put a value on the integer you put you just did if(sscanf(params,"s",nu)) there is should be a value so it will count your characters or letters

[YesYesYes]

ahmmmm.... maybe increase the size of the string??

Sscanf splits the parameters, if you only have a one-parameter command (which you do), you don't need sscanf. Using params directly is better in that case, as it's faster - you don't need to split.


Also to make it clear: "isnull" isn't a "method" for making multi-parameter commands. Isnull is a function that checks if the string that the player entered is empty. Isnull is just a check, nothing else.

Why would you use sscanf when you can just directly use "params"?


Here's a little example, a command with sscanf:

pawn Код:

CMD:asd(playerid, params[]) {
    new string[128];
    if(sscanf(params, "s[128]", string)) return SendClientMessage(playerid, -1, "You haven't entered anything after '/asd'");
    printf("%s", string);
    return 1;
}

In that command, we created a string variable, after that sscanf took out the string part from params[] - but it didn't have to, because there's nothing to take out as it's only string.
We're pretty much splitting params from params.

You could just do it this way:

pawn Код:

CMD:asd(playerid, params[]) {
    if(isnull(params)) return SendClientMessage(playerid, -1, "You haven't entered anything after '/asd'");
    printf("%s", params);
    return 1;
}

We just printed the params because we don't have to split anything from it anyway.
