I'm trying to make a command that when you type in /i(nventory), it will give you a prompt saying "Command Usage: /i [use/discard]"

However, I have no clue how to have the script detect when someone typed in "use" or "discard", at the moment, it just says "Command Usage: /i use [inventory slot]", no matter what I type in for /i

pawn Код:

CMD:i(playerid, params[])
{
    if(GetPVarInt(playerid, "LoggedIn") == 0) return SendClientMessage(playerid, -1, "ERROR: You are not logged in.");
    new string[128], use[4], discard[8], slot, Float: HP;
    if(sscanf(params, "")) return SendClientMessage(playerid, -1, "Command Usage: /i [use/discard]");
    if(!strcmp(use, "use"))
    {
          if(sscanf(params, "i", slot)) return SendClientMessage(playerid, -1, "Command Usage: /i use [inventory slot]");

It'd be real great if anyone could help me with this.

new choice[8];
if(sscanf(params,"s[8]",choice)) return SendClientMessage(playerid, -1, "Command Usage: /i [use/discard]");
if(!strcmp(choice,"use",true,3)) //function 
else if(!strcmp(choice,"discard",true,7)) //function

    else if(!(2 < strlen(params) < sizeof(str)) || sscanf(params,"s[8]",str)) SendClientMessage(playerid, -1, "Command Usage: /i [use/discard]");
    else if(!strcmp(str, "use"))
    {
        new slot;
        if(sscanf(params, "{s[8]}i", slot)) SendClientMessage(playerid, -1, "Command Usage: /i use [inventory slot]");
        else{

    }

This helped, but now the script can't detect that I'm entering a value for "slot", so it just brings "Command Usage: /i use [inventory slot] back up.

    new usage[20],slot;
    if(GetPVarInt(playerid, "LoggedIn") == 0) return SendClientMessage(playerid, -1, "ERROR: You are not logged in.");
    if(isnull(params))  return SendClientMessage(playerid, -1, "Command Usage: /i [use/discard]");
    if(sscanf(params,"s[15]i",usage,slot) return SendClientMessage(playerid, -1, "Command Usage: /i [use/discard]");
    if(!strcmp(usage,"use",true)
    {
        //your command for the use parameter
        //remember ur value of the inventory slot is slot
    }
    else if(!strcmp(usage,"discard",true)
    {
    
            //your command for the discard param
            //remember ur value of the inventory slot is the slot variable
    }

Then the solution is already here.
Using Quickie's code will check for 2 params in the beginning itself and won't respond to /i discard, properly.
But the code that Jeff has posted will do exactly what you wanted.
The {} in the sscanf code is called quiet section and will read the value but will not store it in a variable which actually fulfills your purpose.
Read ******' sscanf documentation to know more about it.

Use ID's on the variable usage instead.
