A better explanation would be that EOS is '/0' which means EOS (End Of String)

Isn't it \0?

Re: Useful Functions - Basicz - 28.08.2011

Another version ( loops ), tested with Slice's benchmark code, it's faster.
( Also removed invalid character checks for the test on both function; nor the oneCharAllowed ).

pawn Код:

stock getPlayerFirstName( playerid )
{
    new
        playerName[ 24 ]
    ;

    GetPlayerName( playerid, playerName, 24 );

    for ( new i, nameLen = strlen( playerName ); i != nameLen; ++ i )
    {
        if ( playerName[ i ] == '_' && i > 0 )
        {
            playerName[ i ] = EOS;
        }
    }

    return playerName;
}

And thanks for the help!

Re: Useful Functions - RyDeR` - 28.08.2011

You don't need all of that actually, the one with strfind was good. This here is even faster I guess:

pawn Код:

stock getPlayerFirstName(playerid)
{
    new
        szName[MAX_PLAYER_NAME],
        iPos
    ;
    GetPlayerName(playerid, szName, sizeof(szName));
    
    iPos = strfind(szName, "_");
    
    if(iPos != -1)
        szName[iPos] = EOS;
        
    return szName;
}

Edit: I deem this impossible to script accurately because the OnVehiclePaintjob gets called if you view a piantjob according to the wiki, so it would mean that it sets the paintjob to whatever was viewed

Edit: after tough thinking i decided to just post the script I had already written, not yet tested, i left in the Modshop detection but comment it out. Thanks ryder because i had looked at what your script for the vehicle colors did to get some hints for this one.

pawn Код:

//GetPaintjob
new veh_paintjob_array[MAX_VEHICLES];
#define ChangeVehiclePaintjob(%1,%2); \
    veh_paintjob_array[(%1 - 1)] = %2; \
    ChangeVehiclePaintjob( %1, %2);
// Uncomment the following comment block to enable paintjob detection (Not very accurate) for piantjobs set in modshops
    /*
public OnVehiclePaintjob(playerid, vehicleid, paintjobid)
{
    veh_paintjob_array[(vehicleid - 1)] = paintjobid;
        old_OnVehiclePaintjob( playerid, vehicleid, paintjobid);
    return 1;
}
forward old_OnVehiclePaintjob(playerid, vehicleid, paintjobid);
#define OnVehiclePaintjob old_OnVehiclePaintjob
*/
//stock GetVehiclePaintjob(vehicleid) { return veh_paintjob_array[(vehicleid - 1)]; }
#define GetVehiclePaintjob(%1); veh_paintjob_array[(%1 - 1)];
#define DestroyVehicle(%1, \
    veh_paintjob_array[(vehicleid - 1)] = 0;\
    DestroyVehicle( %1,

Edit.. again: changed the GetVehiclePaintjob to a define, bit quicker i think.

GetIP, faster than making variable, than use GetPlayerIp....

pawn Код:

stock GetIP(playerid)
{
    new PIP[16];
    GetPlayerIp(playerid, PIP, sizeof(PIP));
    return PIP;
}

Re: Useful Functions - [H]ead - 07.09.2011

Advise use variable type static or global variable, once when GetPlayerIp reset string to allocate the player andress ip

Faster if you create a global variable instead local one.

Re: Useful Functions - [H]ead - 07.09.2011

A static variable is static on scope (

), so, have a speed similar to global variable (is more slower, yes).

So, she is static (global) in the current scope. It was not exactly what I said?

I may as well use global variables, or is the point of it to keep scripts ordered nicely, without having a huge list of global declarations at the top of the script?

They are useful.
Are not equal to global variables, because they are declared only in the current scope ..

pawn Код:

public OnPlayerSpawn(playerid)
{
    static
        lastPlayerSpawn
    ;
        
    printf("The last player on spawn is playerid %d", lastPlayerSpawn);
    return lastPlayerSpawn = playerid;
}
// It remains the old value and unreported in other scopes (only by declaring again)

The best definition would be:
Are global variables in a single scope (not the entire code)

Re: Useful Functions - KoczkaHUN - 07.09.2011

Proof of Y-Less' Concept:

pawn Код:

#include <a_samp>

new globalVar1 = 1;
static globalStaticVar2 = 2;
main(){}

public OnFilterScriptInit()
{
    static staticVar3 = 3;
    staticVar3 = random(1000);
    doSomethingRandomWoohoo();
    printf("%d %d %d", globalVar1, globalStaticVar2, staticVar3);
    return 1;
}

stock doSomethingRandomWoohoo()
{
    globalVar1 = random(21000);
    globalStaticVar2 = random(210000);
    return 1;
}

decompiled:

pawn Код:

#include <a_samp>
#include <core>
#include <float>

new glob0 = 1;

new glob4 = 2;

new glob8 = 3;


main()
{
    return 0;
}

public OnFilterScriptInit()
{
    glob8 = random(1000);
    functionA8();
    printf("%d %d %d", 0, 4, 8);
    return 1;
}

functionA8()
{
    glob0 = random(21000);
    glob4 = random(210000);
    return 1;
}

So the static is like "new" but its dont get resetted evrey time the callback is called?

        #undef MAX_PLAYERS

    #define MAX_PLAYERS (DEFINE SLOTS HERE PLEASE)

    {
        p[++a] = min;    
    }

    return a == -1 ? -1 : p[random(a)]: 
}

Cordially [H]ead

can someone explane this?

If the static variable has already been created the it isn't "Re Created" i think at compile time the var is actually placed outside of all the functions because it acts as a global var.

That's the closest I think you can get it to typing as in a console, or:

pawn Код:

#define loadfs%0"%1" LoadFS(#%1);

loadfs "iradio"

A little closer to your version and using standard strings without the <> or ;.

Thanks

I did't know that attaching %0 to loadfs without space will work even with a space
(Sorry for bad grammar XD)

retx and rety is where it stores the value, correct?

In cmd.exe:

pawncc.exe JunkBuster.pwn -a

(moved JunkBuster.pwn to pawno folder)

You should also put these:

Код:

-; -(

Those are used in PAWNO, by default. Without them, you might get really strange errors.
