That can be improved to:

pawn Код:

stock GetVehicleType(model)
{
    if(model < 400 || model > 611) return 0;
    switch(model)
    {
        case 472, 473, 493, 595, 484, 430, 453, 452, 446: return 1; // Water
        case 417, 425, 447, 460, 469, 476, 487, 488, 497, 511, 512, 513, 519, 520,
        548, 553, 563, 577, 592, 593, 464, 465, 501: return 2; // Air
        default: return 3; // Land
    }
    return 0;
}

So invalid models won't return 3.

Crash a player.
It's usefull.
The command on hisself, isnt usefull.
But the crash is.
(To Ban/kick + Crash hackers etc.) (Hackers can avoid kicks).
Also this snippet can be avoided, but not that easy as Kick.

pawn Код:

CMD:crash(playerid, params[])
{
    new string[128], playerb;
    if(!IsPlayerLoggedIn(playerid)) return SendClientMessage(playerid, COLOR_GREY, "You need to login first before using any command.");
    if(PlayerInfo[playerid][pAdmin] < 4) return SendClientMessage(playerid, COLOR_GREY, "You are not authorized to use this command.");
    if(!aDuty[playerid]) return SendClientMessage(playerid, COLOR_GREY, "You are not on Admin Duty.");
    if(sscanf(params, "u", playerb)) return SendClientMessage(playerid, COLOR_WHITE, "[Usage]: /crash [playerid]");
    if(PlayerInfo[playerid][pAdmin] < PlayerInfo[playerb][pAdmin]) return SendClientMessage(playerid, COLOR_GREY, "Player has a higher admin level than you.");
    GameTextForPlayer(playerb, "•¤¶§!$$%&'()*+,-./01~!@#$^&*()_-+={[}]:;'<,>.?/", 1000, 0);
    GameTextForPlayer(playerb, "•¤¶§!$$%&'()*+,-./01~!@#$^&*()_-+={[}]:;'<,>.?/", 2000, 1);

    GameTextForPlayer(playerb, "•¤¶§!$$%&'()*+,-./01~!@#$^&*()_-+={[}]:;'<,>.?/", 7000, 6);
        SendClientMessage(playerid, COLOR_WHITE, ""&#8226;¤¶§!$$%&'()*+,-./01~!@#$^&*()_-+={[}]:;'<,>.?/");

        SendClientMessage(playerid, COLOR_WHITE, ""&#8226;¤¶§!$$%&'()*+,-./01~!@#$^&*()_-+={[}]:;'<,>.?/");
    format(string, sizeof(string), "You have crashed %s 's game", RPN(playerb));

Very simple but useful:

PHP код:



stock GetMinute()

{

    new Hour,Minute,Second;

    gettime(Hour,Minute,Second);

    return Minute;

}

stock GetDay()

{

    new Year,Month,Day;

    getdate(Year, Month, Day);

    return Day;

}

stock GetMonth()

{

    new Year,Month,Day;

    getdate(Year, Month, Day);

    return Month;

}

stock GetYear()

{

    new Year,Month,Day;

    getdate(Year, Month, Day);

    return Year;

}

stock GetSecond()

{

    new Hour,Minute,Second;

    gettime(Hour,Minute,Second);

    return Second;

}

stock GetHour()

{

    new Hour,Minute,Second;

    gettime(Hour,Minute,Second);

    return Hour;

}

stock IsLeapYear(year)

{

    switch(year)

    {

        case 2012: return 1;

        case 2016: return 1;

        case 2020: return 1;

        case 2024: return 1;

        case 2028: return 1;

        case 2032: return 1;

        case 2036: return 1;

    }

    return 0;

}

stock GetDaysInMonth(month)

{

    new Year,Month,Day,days;

    getdate(Year, Month, Day);

    switch(month)

    {

        case 1: days = 31;

        case 2:

        {

            if(IsLeapYear(Year)) days = 29;

            else days = 28;

        }

        case 3: days = 31;

        case 4: days = 30;

        case 5: days = 31;

        case 6: days = 30;

Re: Useful Snippets - Slice - 16.07.2013

The server still closes the connection, so I don't see how it would change anything.

Re: Useful Snippets - Luis- - 16.07.2013

Plus the crashing code wouldn't work on most players codes, you gotta include the stock codes too.

Re: Useful Snippets - HuSs3n - 16.07.2013

Make a color darker\lighter

pawn Код:

stock ColorLighten(colour,Float:Amount)
{
    new a = colour & 0xFF;
    new r=min(255, ((colour >> 24) & 0xFF)+ floatround(255 * Amount));
    new g=min(255, ((colour >> 16) & 0xFF)+ floatround(255 * Amount));
    new b=min(255, ((colour >> 8) & 0xFF)+ floatround(255 * Amount));
    return (r<<24 | g<<16 | b<<8 | a);
}

stock ColorDarken(colour,Float:Amount)
{
    new a = colour & 0xFF;
    new r=max(0, ((colour >> 24) & 0xFF)- floatround(255 * Amount));
    new g=max(0, ((colour >> 16) & 0xFF)- floatround(255 * Amount));
    new b=max(0, ((colour >> 8) & 0xFF)- floatround(255 * Amount));
    return (r<<24 | g<<16 | b<<8 | a);
}

(Amount used is 0.3)

Re: Useful Snippets - Emmet_ - 23.09.2013

Haven't posted in this thread in a while..

The script below was just something simple I made. It's a 100% accurate bunnyhop detection script. Most scripts just detect KEY_JUMP being pressed, but my script actually checks if the player is indeed jumping.

The more you know: bunnyhopping is spamming the jump key to get somewhere faster.

pawn Код:

// Bunnyhop Detection
#include <a_samp>

new g_JumpCount[MAX_PLAYERS char];
new g_JumpTime[MAX_PLAYERS];

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if (GetPlayerState(playerid) == PLAYER_STATE_ONFOOT && GetPlayerAnimationIndex(playerid) == 1198)
    {
        if (GetTickCount() - g_JumpTime[playerid] >= 500)
        {
            if (++g_JumpCount{playerid} > 4)
            {
                // Your code here!
                g_JumpCount{playerid} = 0;
            }
            g_JumpTime[playerid] = GetTickCount() + 500;
        }
    }
    return 1;
}

AW: Useful Snippets - ThomasTailor93 - 24.09.2013

What's the difference between

pawn Код:

g_JumpCount[playerid] = 0; or g_JumpCount{playerid} = 0;

and

pawn Код:

new g_JumpCount[MAX_PLAYERS]; or new g_JumpCount[MAX_PLAYERS char];

Re: Useful Snippets - Emmet_ - 14.10.2013

My own way of inline formatting:

pawn Код:

stock gFormatString[2048 char];

#define _format(%0,%1) \
    (format(!gFormatString, sizeof(gFormatString), %0, %1), !gFormatString)

Got the idea one day when RealCop228 replied to the Useful Functions thread about my long SendClientMessageEx function, and I also got the prefix idea from Slice's translate.inc include (thanks to them).

So basically, with a little tweaking, you can now format strings very easily:

pawn Код:

SendClientMessage(playerid, COLOR_WHITE, _format("You have $%d. You are very rich!", GetPlayerMoney(playerid));

Last year, I made a non-macro version of the same function, but it's very inefficient since I wasn't actually very good at efficiency-wise scripting last year.

EDIT: I should probably clarify. The reason why it's 512 cells (no, not 2048, it's a packed array) is because you might want to use the function for long inputs, such as MySQL queries and such.

Re: Useful Snippets - Misiur - 14.10.2013

SendClientMessage can use packed strings? TIL, thanks

#e: Ah, mea culpa, ! is negation and only indicates packing before string constant

"format" doesn't support packed strings, you're corrupting data at address 0 (exclamation mark in front of the array) and it can't be split into multiple lines!

Well, I've only tested it with client messages with success, but I didn't manage to test it thoroughly with things like larger outputs. Stupid me, thanks for noticing that ;d

EDIT: Maybe I should stop trying to make low-leveled shit. I fail miserably at it.

Re: Useful Snippets - Slice - 14.10.2013

You didn't fail miserably, you just mixed a few things up! It happens.

You also helped finding a new way of making pointers, which is much faster compared to the previous version!
