how to make a cmd views params and no params! - KillerStrike23 - 27.06.2014

hello I had created this saving skin cmd but I need to make it if player doesn't put any params like only cmd /skin it will force him to class selection but if player used skin numbers it will save him the skin!

my code

pawn Код:

CMD:skin(playerid,params[]) {
    if(PlayerInfo[playerid][LoggedIn] == 1) {
        if(isnull(params)) {
            new SkinID = strval(params);
            if(SkinID < 299) {
                dUserSetINT(PlayerName2(playerid)).("FavSkin",SkinID);
                dUserSetINT(PlayerName2(playerid)).("UseSkin",1);
                SetPlayerSkin(playerid,SkinID);
            } else SendClientMessage(playerid,0xFF0000AA,"error: Available Skins: 0 - 299 !");
    } else SendClientMessage(playerid,red,"ERROR: You must be logged in to use this command");
    return 1;}

Force Class

pawn Код:

if(PlayerInfo[playerid][Jailed] == 1) return SendClientMessage(playerid,COLOR_BRIGHTRED,"You cannot escape your punishment!");
        SetPlayerHealth(playerid, 0.0);
        ForceClassSelection(playerid);
        if(IsPlayerInAnyVehicle(playerid)) {
            if(VehicleInfo[GetPlayerVehicleID(playerid)][Temp] == 1) SetTimerEx("EraseVehicle", 5000,0,"i",GetPlayerVehicleID(playerid));}

pawn Код:

CMD:skin(playerid,params[])
{
    if(!PlayerInfo[playerid][LoggedIn]) return SendClientMessage(playerid, red, "ERROR: You must be logged in to use this command");
    if(params[0] == EOS) return SendClientMessage(playerid, red, "USAGE: /skin [skin id]");
    new skin = strval(params);
    if(!(-1 < skin < 300)) return SendClientMessage(playerid, red, "ERROR: Available Skins: 0 - 299 !");
    dUserSetINT(PlayerName2(playerid)).("FavSkin", skin);
    dUserSetINT(PlayerName2(playerid)).("UseSkin", 1);
    SetPlayerSkin(playerid, skin);
    return 1;
}

'if(params[0] == EOS)' checks if the string 'params' is empty or not.

pawn Код:

ForceClassSelection(playerid);
SetPlayerHealth(playerid, 0.0);

'ForceClassSelection' must be called BEFORE the player dies/respawns. Otherwise it will only take effect after the next death/respawn

Your usage of "isnull" is incorrect. Try:

pawn Код:

CMD:skin(playerid,params[]) {
    if(PlayerInfo[playerid][LoggedIn] == 1) {
        if(!isnull(params)) {
            new SkinID = strval(params);
            if(SkinID < 299) {
                dUserSetINT(PlayerName2(playerid)).("FavSkin",SkinID);
                dUserSetINT(PlayerName2(playerid)).("UseSkin",1);
                SetPlayerSkin(playerid,SkinID);
            } else SendClientMessage(playerid,0xFF0000AA,"error: Available Skins: 0 - 299 !");
    } else SendClientMessage(playerid,red,"ERROR: You must be logged in to use this command");
    return 1;
}
