Hi,

I want to ask.

When you use only one parameter in command like:

/heal [player name/id]

There not need to use sscanf? you can use params, but how them use?

I don't use sscanf when i only use one parameter on a command (:

if it's just /heal (playerid) it should be like this (if you are using ZCMD

pawn Code:

#if !defined isnull
    #define isnull(%1) \
                ((!(%1[0])) || (((%1[0]) == '\1') && (!(%1[1]))))
#endif

pawn Code:

CMD:heal(playerid, params[])
{

    if (isnull(params)) return SendClientMessage(playerid, -1, "Usage: /heal <playerid>");
    if (strval(params)==INVALID_PLAYER_ID) return SendClientMessage(playerid, -1, "Invalid player id");
    new id;
    id = strval(params);
    SetPlayerHealth(id, 100);
    SendClientMessage(id, -1, "You have been healed");
    return 1;
}

not sure about the [playername/id] in the same time , for that, I just use sscanf, sorry I'm a beginner also

As he said, you can sipmy sscanf, unless you need only one parameter which is a string

here example with sscanf and zcmd

Code:

CMD:sethp(playerid, params[])
{
	new playerb, amount, string[128];
    if(sscanf(params, "ui", playerb, amount)) return SendClientMessage(playerid, COLOR_WHITE, "USAGE: /sethp [playerid] [amount]");
    if(!IsPlayerLoggedIn(playerb)) return SendClientMessage(playerid, COLOR_GREY, "Invalid player id.");
    SetPlayerHealth(playerb, amount);
    return 1;
}
