Lorenc:
Your code will not work with variations of hacking (Example: 9999999.999 to 99999.99999

)

You can use || ('or' operator) but this cleo has massive integers installed.. Anyway, your one wouldn't work with different variations as well.

0xDBB9F = 899999

0xF423F = 999999 (Which is what I have, except with some decimal numbers)

Hexidecimal is neat. Anyway, about PVars, I don't use one PVar inside my gamemode, and don't want to lol. Char arrays, and other techniques keep me away from it.

PVars are dynamic memory, you'll easily notice better speed in the compilation. But really, not worth using them if you take into account the speed. But I think they're very flexible for those who do not have time to let the "perfect code". Do you agree?

In "script x script" is quite feasible using CallRemoteFunction.

So we need put a value LESS.

Re: Useful Snippets - Lorenc_ - 13.07.2012

I can't be bothered going in-game to test, but I'll only say that 20,000 should be fine also.

Also, like ****** said about compile time checking, what if you misspell a PVar? Since they are strings not labels an error like this would be annoying!

Anyway, I really should get this back on topic by posting a useful snippet... Can't think of any that I haven't posted already though

This is what I'm talking about

Slice released code similar to "PVARS". It pays to use it?

Velocity is the only possible way afaik (vehicle velocity of the Z axis).

Usage

Код:

GameTextForPlayerEx(playerid,"Firecat still lives in 2007",3500,3,playerid);

Why would you move a perfectly good local to a global?

Your example makes no sense, because you're not using params.
As Y_Less asked, why did you turn a local variable to global?

Re: Useful Snippets - Y_Less - 20.07.2012

Also, that code won't work with no format parameters.

Respuesta: Useful Snippets - JoBullet - 20.07.2012

It also won't compile because variable declaration contains space at invalid position.

No need for formulas
https://sampwiki.blast.hk/wiki/GetVehicleVelocity
Store the z axis, and check it for example if(z > 1)...
Because z is height

Re: Useful Snippets - BaubaS - 20.07.2012

I thought velocity works a bit different. But will this really work when player for example is on ch. mountain?

Re: Useful Snippets - Slice - 20.07.2012

Velocity has nothing to do with where you are. It has to do with how fast you're moving, and in which direction.

pawn Код:

#define SendMessage(%0,%1,%2,%3)            do{new smStr[128];format(smStr,128,%2,%3);SendClientMessage(%0,%1,smStr);}while(FALSE)
#define GameTextForPlayerEx(%0,%1,%2,%3,%4) do{new gTFPE[150];format(gTFPE,150,%1,%4);GameTextForPlayer(%0,gTFPE,%2,%3);}while(FALSE)
#define GameTextForAllEx(%0,%1,%2,%3)       do{new gTFA[150];format(gTFA,150,%0,%3);GameTextForAll(gTFA,%1,%2);}while(FALSE)

stock bool:FALSE = false;

I always use those variables inside the do{} stuff.

WARNING: You cannot use these function things in a return statement thing.
Example, this will not work:

pawn Код:

if (!IsPlayerConnected(id)) return SendMessage(playerid, 0xFF0000AA, "Playerid %d is not connected!", id);

Why? Before PAWNO is going to compile your gamemode, it will first change these functions as how it is in the #define. So this code above actually will look like this:

pawn Код:

if (!IsPlayerConnected(id)) return do{new smStr[128];format(smStr,128,"Playerid %d is not connected!,id);SendClientMessage(playerid,0xFF0000AA,smStr);}while(FALSE)

If you try to compile both these codes, you'll get the same errors (except when you don't define the SendMessage off course)

heres a version of all, that do support returns, and do support no parameters(and also includes a "SendMessageToAll").

Functions:

pawn Код:

GameTextForPlayerEx(playerid, string[], time, style, {Float,_}:...);
GameTextForAllEx(string[], time, style, {Float,_}:...);
SendMessage(playerid, color, message[], {Float,_}:...);
SendMessageToAll(color, message[], {Float,_}:...);

Code:

pawn Код:

#if !defined FMsg
    stock FMsg[400];
#endif

stock GameTextForPlayerEx(playerid,const string[],time,style)return GameTextForPlayer(playerid,string,time,style);
#define GameTextForPlayerEx(%0,%1,%2,%3,%4) format(FMsg, sizeof(FMsg),%1,%4), GameTextForPlayer(%0,FMsg,%2,%3)

stock GameTextForAllEx(const string[],time,style)return GameTextForAll(string,time,style);
#define GameTextForAllEx(%0,%1,%2,%3) format(FMsg, sizeof(FMsg),%0,%3), GameTextForAll(FMsg,%1,%2)

#define SendMessage(%0,%1,%2) format(FMsg, sizeof(FMsg), %2), SendClientMessage(%0,%1,FMsg)
#define SendMessageToAll(%0,%1) format(FMsg, sizeof(FMsg), %1), SendClientMessageToAll(%0,FMsg)

This stock functions will check if if vehicle is a boat or an airplane/helicopter

stock IsWaterVehicle(model)

-code-

I wrote something like that earlier ago (1 week) however I didn't share it publicly.

pawn Код:

stock IsBoatVehicle( model )
{
    static const
        BoatVehicles[ ] = {
            472, 473, 595, 493, 430, 453, 484, 446, 452, 454
        }
    ;

    for( new i; i < sizeof( BoatVehicles ); i++ ) {
        if( BoatVehicles[ i ] == model ) return 1;
    }
    return 0;
}

stock IsAirVehicle( model )
{
    static const
        AirVehicles[ ] = {
            577, 511, 592, 520, 593, 512, 476, 553, 460, 519, 548, 425, 488, 487, 417, 563, 497, 447, 469
        }
    ;
    
    for( new i; i < sizeof( AirVehicles ); i++ ) {
        if( AirVehicles[ i ] == model ) return 1;
    }
    return 0;
}

They're functions anyway...

pawn Код:

stock IsPlayerFemale(Model) {
    if(Model < 0 || Model > 299) {
        return false;
    }

    static const Female[] = {

        178, 190, 191, 192, 193, 194, 195, 196, 197, 198, 199, 201, 205, 207, 211, 214, 215, 216, 218, 219, 224, 225, 226, 231, 232, 233, 237, 238, 243, 244, 245, 246, 251, 256, 257, 263, 298
    };

    for(new FemaleID = 0; FemaleID < sizeof(Female); FemaleID++) {
        if(Female[FemaleID] == Model) {
            return true;
        }
    }
    return false;
}

stock IsPlayerSkin(Model) {
    if(IsPlayerMale(Model) || IsPlayerFeamle(Model)) {
        return true;
    }
    return false;
}

Report the missing or misplaced skins by sending me a private message please.

Are they those "IsThisASomething" functions where you have an array of hex numbers then an if statement with some bitwise shifting and stuff... It's hard to explain, I've seen some posted before, I never understood them and I don't really know what keywords to use to search (apart from "bit array" but I didn't really find anything)

I may as well ask while it's on topic!

It's an extension of storing 32 bools in one variable - it stores 32*x bools in an array. When reading bits 1-32, the first cell is used, 32-64 second cell, etc. So for example, slot 123 would be the 27th bit in bit_array[3].

Yes, they're what you've seen in some IsThisASomething. One HUGE example is g_baValidModels in hold-studio.pwn. For readability, I used binary notation instead of numbers or hex.

enum type
{
    TYPE_UNKNOWN,
    TYPE_LAND,
    TYPE_WATER,
    // ...
}

new vehicleTypes[212 char] = { 16777216 /* 1 << 24 */, ... };
