Erm, i've tried to type • in chat at a few servers, including my own, and nothing happened.. Nothing crashed or whatever :P. You just see 'Robin: ', and not 'Robin: •'

erm? :P

Robin,only Work in Windows XP.

@[FeK]DraKiNs:
I guess it will be better if you just add an amount to the vehicleid. Then vehicles never have odds to have the same numberplate (how they also are) and it's better instead random numbers I guess.

pawn Код:

stock CreateRandomNumberPlate(vehicleid)
{
    new
        string[8]
    ;
    format(string, sizeof(string), "NUM-%d", (vehicleid + 1000));
    SetVehicleNumberPlate(vehicleid, string);
    SetVehicleToRespawn(vehicleid);
    return vehicleid;
}

Re: Useful Functions - CyNiC - 05.01.2011

pawn Код:

IsPlayerStopped(playerid)
{
    if(GetPlayerAnimationIndex(playerid) == 1189) return true;
    return false;
}

@RyDeR

Oh Ye,Good Idea,but is Plate RAMDOM:

But here:

Plate Cars

pawn Код:

stock CreateVehicleNumberPlate(vehicleid)
{
    static
        sPlate[22];
    format(sPlate,22,"Plate: %d",(1000 + vehicleid));
    SetVehicleNumberPlate(vehicleid,sPlate);
    return SetVehicleToRespawn(vehicleid);  
}

Thanks

@Cynic
What this code do?

Re: Useful Functions - CyNiC - 05.01.2011

Checks if the player is doing nothing.

Ok,Thanks

Give Value To PVARs

pawn Код:

stock
    GivePVarInt(playerid, var[], val)                                           //- PVars++
        return SetPVarInt(playerid,var,GetPVarInt(playerid, var)+val);

Crash Player in 0.3b

pawn Код:

stock
    CrashPlayer(playerid)                                                       //- Crash the Player (0.3b)
        SetPlayerHoldingObject(playerid, 0, 0);

Get ID Player From Part Name

pawn Код:

Re: Useful Functions - [03]Garsino - 05.01.2011

Use macros for your first 2 functions

(I already made the first one though, not sure if I posted it in the topic or not).

Respuesta: Useful Functions - ipsBruno - 06.01.2011

@[03]Garsino
Ya,is + best using macros,but i like stocks,sorry.

GetBiggestArrayNumber

pawn Код:

stock GetBiggestArrayNumber(array[], len = sizeof(array))
{
    new
        biggest = cellmin
    ;
    for(new i ; i != len; ++i)
    {
        if(array[i] > biggest)
        {
            biggest = array[i];
        }
    }
    return biggest;
}

GetSmallestArrayNumber

pawn Код:

stock GetSmallestArrayNumber(array[], len = sizeof(array))
{
    new
        smallest = cellmax
    ;
    for(new i ; i != len; ++i)
    {
        if(array[i] < smallest)
        {
            smallest = array[i];
        }
    }
    return smallest;
}

Loop String

pawn Код:

#define sLoop(%0,%1) for(new %1; %0[%1]; ++%1)

Use:

pawn Код:

sLoop(string,i)
{
     printf("Char %s",string[i]);
}

Loop String

Simple loop for string (best for not use strlen)

Re: Useful Functions - RyDeR` - 07.01.2011

GetNumArgs

pawn Код:

stock GetNumArgs(var[], ...)
{
    for(new i = 1; i != numargs(); ++i)
    {
        var[(i - 1)] = getarg(i);
    }
    return 1;
}

Example

pawn Код:

new
    var[4]
;
GetNumArgs(var, 1, 5, 9, 4);
printf("Numbers stored in array var are: %d %d %d %d", var[0], var[1], var[2], var[3]);

Will give us:

Код:

Numbers stored in array var are 1 5 9 4

GetStringArgs

pawn Код:

stock GetStringArgs(string[][], ...)
{
    for(new i = 1; i != numargs(); ++i)
    {
        for(new x; getarg(i, x) != 0; ++x)
        {
            string[(i - 1)][x] = getarg(i, x);
        }
    }
    return 1;
}

Example

pawn Код:

new
    string[4][16]
;
GetStringArgs(string, "My", "Nick", "Is", "RyDeR`");
printf("Strings stored in 2D array string are: %s %s %s %s", string[0], string[1], string[2], string[3]);

Will give us:

Код:

Strings stored in 2D array string are: My Nick Is RyDeR`

Notice: These functions are just to give you more information about the usage of args.

Re: Useful Functions - Aleks10 - 07.01.2011

GetBiggestArrayNumber and GetSmallestArrayNumber not true.

Re: Useful Functions - RyDeR` - 07.01.2011

As far as I tested they both do work perfect.

Simple loop for string (best for not use strlen)

Using a for-loop with strlen is a lot faster actually.

Re: Useful Functions - RyDeR` - 07.01.2011

@Slice:
It's not. The way DraKiNs uses is a lot faster.

EDIT: Just did a speedtest and realised that strlen is almost 3 times slower. This way:

pawn Код:

for(new i; i != strlen(string); ++i)

EDIT2: You're right if we assign the return (of strlen) to a variable first, and I also think this was what you meant.

pawn Код:

for(new i, j = strlen(string); i != j; ++i)

Re: Useful Functions - Grim_ - 07.01.2011

I'm assuming you're talking about checking the value returned by strlen( ) each increment. Try this code compared to his:

pawn Код:

for( new i = 0, j = strlen( string ); i < j; i++ )

Re: Useful Functions - RyDeR` - 07.01.2011

Huh, indeed; that's a little bit faster. Didn't know that.

Respuesta: Useful Functions - ipsBruno - 07.01.2011

@Ryder

Yes,Is right, this form is like a foreach to string.

Of course nothing very optimized.

Equals:

pawn Код:

while (i <10) if (string [i]! = EOS)

And I still used '++i' which further optimizes the code.

@Grim:
The method is good, but use ++array and not array++ for optimizes a little more

Thanks

Re: Useful Functions - Aleks10 - 08.01.2011

RyDeR`, no, no true...
new arr[10] = {-10,-20,-100,-100,-500,-7,-1,-5,-8}; ...
true version:

Код:

stock GetBiggestArrayNumber(array[], len = sizeof(array))
{
    new biggest=-2147483647;
    for(new i=0; i != len; ++i)
		if(array[i] > biggest)
            biggest = array[i];
    return biggest;
}
stock GetSmallestArrayNumber(array[], len = sizeof(array))
{
    new smallest=2147483647;
    for(new i; i != len; ++i)
        if(array[i] < smallest)
            smallest = array[i];
    return smallest;
}
