Hi again. I ask a question here which is about loops.

I got this loop:

pawn Код:

for (new i = 0; i != count; ++i)
    {
        format(string,sizeof(string),"/%s",Command_GetNext(i, playerid));
        SendInfoMessage(playerid, string);
    }

Which adds up all commands in a list like this:

Код:

/commands
/help
/admins

and so on.

What I want is to make the loop count +5 everytime it finishes.
So that I can change the command format to:

pawn Код:

for (new i = 0; i != count; ++i)
    {
        format(string,sizeof(string),"/%s /%s /%s /%s /%s",Command_GetNext(i, playerid),Command_GetNext(i+1, playerid),Command_GetNext(i+2, playerid),Command_GetNext(i+3, playerid),Command_GetNext(i+4, playerid));
        SendInfoMessage(playerid, string);
    }

Any help is accepted.

EDIT: Also, how do I check if the "Command_GetNext" returns nothing, so that I don't end up with:

pawn Код:

/help /commands / / /

if there's only 2 commands available.

Thanks. Do you have any idea on the loop?

Just increase the loop by 5:

pawn Код:

for (new i = 0; i != count; i += 5)

Thanks I'll try to put the rest together myself.

EDIT: How do I put the buffer[0] thing inside the string?

pawn Код:

for (new i = 0; i < count; i+=4)
    {
        format(string,sizeof(string),"/%s /%s /%s /%s /%s",Command_GetNext(i, playerid),Command_GetNext(i+1, playerid),Command_GetNext(i+2, playerid),Command_GetNext(i+3, playerid),Command_GetNext(i+4, playerid));
        SendInfoMessage(playerid, string);
    }

I don't want to end up with

pawn Код:

/help /commands / / /

Yeah, I understand that but what I don't understand is how to format the string depending on how many commands are available?

Right now I end up with having the last line in my /commands like this:

pawn Код:

/veh / / / /

because the format looks like:

pawn Код:

/%s /%s /%s /%s /%s

So basically, I just need to know how to ADD info to a string depending on how many commands there is on the last line. E.g.

pawn Код:

if(buffer[0]) { AddToString(str,"/%s",buffer[0]) } else {return 1;}
if(buffer[1]) { AddToString(str,"/%s",buffer[1]) } else {return 1;}
if(buffer[2]) { AddToString(str,"/%s",buffer[2]) } else {return 1;}
if(buffer[3]) { AddToString(str,"/%s",buffer[3]) } else {return 1;}
if(buffer[4]) { AddToString(str,"/%s",buffer[4]) } else {return 1;}

EDIT: I searched wiki and found "Strins" would that work?

Now I have this command:

pawn Код:

YCMD:commands(playerid, params[], help)
{
    if(help) return SendInfoMessage(playerid,"Shows all available commands to a certain player.");
    new count = Command_GetPlayerCommandCount(playerid);
    new string[128],str[128];
    format(string,sizeof(string),"List of commands for {a9c4e4}%s{FFFFFF}:",pName(playerid));
    SendInfoMessage(playerid,"Type /help [command] for more info.");
    SendInfoMessage(playerid,string);
    for (new i = 0; i < count; i+=5)
    {
        new buffer[YSI_MAX_STRING];
        buffer = Command_GetNext(i, playerid);
        format(str, sizeof (str), "%s /%s", str, buffer);
        SendInfoMessage(playerid, str);
    }
    return 1;
}

Which sends the string each time the loop starts over. And if I change it to:

pawn Код:

YCMD:commands(playerid, params[], help)
{
    if(help) return SendInfoMessage(playerid,"Shows all available commands to a certain player.");
    new count = Command_GetPlayerCommandCount(playerid);
    new string[128],str[128];
    format(string,sizeof(string),"List of commands for {a9c4e4}%s{FFFFFF}:",pName(playerid));
    SendInfoMessage(playerid,"Type /help [command] for more info.");
    SendInfoMessage(playerid,string);
    for (new i = 0; i < count; i+=5)
    {
        new buffer[YSI_MAX_STRING];
        buffer = Command_GetNext(i, playerid);
        format(str, sizeof (str), "%s /%s", str, buffer);
    }
        SendInfoMessage(playerid, str);
    return 1;
}

I end up with getting only 1 row of commands.

love you (Y)

Final Result:

pawn Код:

YCMD:commands(playerid, params[], help)
{
    if(help) return SendInfoMessage(playerid,"Shows all available commands to a certain player.");
    new count = Command_GetPlayerCommandCount(playerid);
    new string[128],str[128];
    format(string,sizeof(string),"List of commands for {a9c4e4}%s{FFFFFF}:",pName(playerid));
    SendInfoMessage(playerid,"Type /help [command] for more info.");
    SendInfoMessage(playerid,string);
    for (new i = 0; i < count; i+=5)
    {
        new buffer[YSI_MAX_STRING];
        buffer = Command_GetNext(i, playerid);
        if(buffer[0] != 0) format(str, sizeof (str), "%s /%s", str, buffer);
        buffer = Command_GetNext(i+1, playerid);
        if(buffer[0] != 0) format(str, sizeof (str), "%s /%s", str, buffer);
        buffer = Command_GetNext(i+2, playerid);
        if(buffer[0] != 0) format(str, sizeof (str), "%s /%s", str, buffer);
        buffer = Command_GetNext(i+3, playerid);
        if(buffer[0] != 0) format(str, sizeof (str), "%s /%s", str, buffer);
        buffer = Command_GetNext(i+4, playerid);
        if(buffer[0] != 0) format(str, sizeof (str), "%s /%s", str, buffer);
        SendInfoMessage(playerid, str);
        format(str,sizeof(str),"");
    }
    return 1;
}

Hope someone more than me got use of it.
Thank you ******.

What does that do? Save CPU power?
