strcmp usage - Snowman12 - 28.01.2012

Hey,

For some reason this doesn't work:

pawn Код:

CMD:drift(playerid, params[])
{
//  if(sscanf(params, "d")) return SCM(playerid, -1, ""COL_RED"Usage:"COL_GREY" /drift "COL_ORANGE"[1 - 53]");
    if(isnull(params)) return SCM(playerid, -1, ""COL_RED"Usage:"COL_GREY" /drift "COL_ORANGE"[1 - 5]");
    if(strcmp("1", params))
    {
        if(IsPlayerInAnyVehicle(playerid))
        {
            if(GetPlayerState(playerid) == PLAYER_STATE_DRIVER)
            {
                SetVehiclePos(GetPlayerVehicleID(playerid),-358.1943,1531.2909,75.1698);
                SetVehicleZAngle(GetPlayerVehicleID(playerid), 264.7289);
                SetCameraBehindPlayer(playerid);
            }
            else return SCM(playerid, -1, ""COL_RED"Error:"COL_GREY" You must be the driver of the vehicle.");
        }
        else
        {
            SetPlayerPos(playerid,-358.1943,1531.2909,75.1698);
            SetPlayerFacingAngle(playerid, 264.7289);
            SetCameraBehindPlayer(playerid);
        }
    }
    if(strcmp(params, "2"))
    {
        if(IsPlayerInAnyVehicle(playerid))

    }

    {
        if(IsPlayerInAnyVehicle(playerid))
        {
            if(GetPlayerState(playerid) == PLAYER_STATE_DRIVER)
            {
                SetVehiclePos(GetPlayerVehicleID(playerid), -2489.8352,-616.3492,132.5658);

        }
        else
        {
            SetPlayerPos(playerid, 1146.2200, 2178.7068, 10.8203);
            SetPlayerFacingAngle(playerid, 178.7448);
            SetCameraBehindPlayer(playerid);
        }
    }
    return 1;
}

Haven't really learned strcmp well but it TPs me to the same locations. Any idea?

Re: strcmp usage - [ABK]Antonio - 28.01.2012

You could probably just use

pawn Код:

new Number = strval(params);

if(Number == 1)
{
    //our stuff
}

strcmp will return 0 if the strings are the same

Instead of this:

pawn Код:

if(strcmp("1", params))

Just do this:

pawn Код:

if(!strcmp("1", params))

EDIT: Also have in mind what the poster above said

Re: strcmp usage - Dokins - 28.01.2012

It's not Strcmp you should use (compares a string, and although it will work if you use

pawn Код:

if(strcmp(params, "1", true))
{
//Code here.
}

You should probably use a more efficient method by making it an integer so that way you can do it like this

if(value == 1)
{
//code
}

It's much more efficient!

See the result given.

But just do what [ABK]Antonio said.

Re: strcmp usage - Mosslah - 28.01.2012

I think you can also use cases, but I'm not entirely sure. I think you should just follow what the posters above told you, as that would work better than strcmp.

Re: strcmp usage - Konstantinos - 28.01.2012

First of all, sscanf doesn't work like that.

pawn Код:

new
    driftid;

    if( sscanf( params, "i", driftid ) ) return SendClientMessage(...);

But in your case, I suggest you to use isnull like you used, without sscanf.
Also,

pawn Код:

if( strcmp( params, "1", true ) == 0 )
{
    if(IsPlayerInAnyVehicle(playerid))
    {
        if(GetPlayerState(playerid) == PLAYER_STATE_DRIVER)
        {
            SetVehiclePos(GetPlayerVehicleID(playerid),-358.1943,1531.2909,75.1698);
            SetVehicleZAngle(GetPlayerVehicleID(playerid), 264.7289);
            SetCameraBehindPlayer(playerid);
        }
        else return SCM(playerid, -1, ""COL_RED"Error:"COL_GREY" You must be the driver of the vehicle.");
    }
    else
    {
        SetPlayerPos(playerid,-358.1943,1531.2909,75.1698);
        SetPlayerFacingAngle(playerid, 264.7289);
        SetCameraBehindPlayer(playerid);
    }
}
// Continue..

Yeah isnull worked best for it thanks for the comments guys
