AMX Mod X Stocks (Custom useful stocks)

Hello,
So I have been coding some private plugins, and I came up with a various set of custom stocks, so I moved them to an include file, and decided to share them, perhaps they can be useful for you and your own plugins!

By including this file, you will not need to include amxmodx module in your plugin as we check it, and if it is not included, it will be automatically included.

Code is available on GitHub @ https://github.com/Chilimax/AMX-Mod-...amx_stocks.inc

I am seriously looking forward some ideas and suggestions to improve this code and make it much more useful :)

You may follow the AMXX doc style. It is helpful to see it/have it.

native heapspace();

/**

 *

 * @return      Function index > 0 on success, -1 if function was not found

native funcidx(const name[]);

/**

native numargs();

/**

native getarg(arg, index = 0);

/**

 *
 * @note This is not equal to assigning a new value to a by-reference argument.
 *
 * @param arg       Argument index

native setarg(arg, index = 0, value);

How can this be helpful mate? What I meant by ideas is new features :P

Looks like there is not much code on it for now, so as it is simpler, there is no problem.
But, just gathering bunches of code together without a proper documentation is not helpful.
At least it is my preference, instead of get on that nightmare, I prefer start a clean notion one from zero.

Re: AMX Mod X Stocks (Custom useful stocks)

I will add notes on each stock :)

Re: AMX Mod X Stocks (Custom useful stocks)

get_connected_target() makes no sense. What is it supposed to be doing?

Re: AMX Mod X Stocks (Custom useful stocks)

you can use it to choose a random connected player :)
get_connected_target( random_num( 1, 32 ) ) I see it pretty useful in plugins which choose a random player regardless if they were dead or alive e.g deathrun terrorist choosing :P

Re: AMX Mod X Stocks (Custom useful stocks)

What about this?:

PHP Code:


		
			
#if !defined MAX_PLAYERS
const MAX_PLAYERS = 32;
#endif

stock GetPlayers(players[MAX_PLAYERS], const predicateFuncName[]) {
#if !defined MaxClients
    static MaxClients = -1;
    if (MaxClients == -1) {
        MaxClients = get_maxplayers();
    }
#endif
    
    new count = 0;
    new predFuncId = get_func_id(predicateFuncName);
    for (new i = 1; i <= MaxClients; i++) {
        callfunc_begin_i(predFuncId);
        callfunc_push_int(i);
        if (bool:callfunc_end()) {
            players[count++] = i;
        }
    }
    
    return count;
}

stock GetRandomPlayers(randomPlayers[], randomPlayerCount, const predicateFuncName[]) {
    static players[MAX_PLAYERS];
    new playerCount = GetPlayers(players, predicateFuncName);
    
    new realCount = min(randomPlayerCount, playerCount);
    for (new i = 0; i < realCount; i++) {
        new rand = random_num(0, playerCount - 1);
        
        randomPlayers[i] = players[rand];
        players[rand] = players[playerCount - 1];
        
        playerCount--;
    }
    
    return realCount;
}

stock GetRandomPlayer(const predicateFuncName[]) {
    new player[1];
    return GetRandomPlayers(player, 1, predicateFuncName) ? player[0] : 0;
}

Example:

PHP Code:


		
			
    register_clcmd("say /smth", "OnClientCommand_Say_Smth");
}

public bool:IsPlayerAliveAdmin(clientEntIndex) {
    return is_user_alive(clientEntIndex) && is_user_admin(clientEntIndex);
}

public OnClientCommand_Say_Smth(clientEntIndex) {
    client_print(clientEntIndex, print_chat, "RandPl: %d", GetRandomPlayer("IsPlayerAliveAdmin"));
    
    static players[MAX_PLAYERS];
    new count = GetRandomPlayers(players, sizeof(players), "IsPlayerAliveAdmin");
    client_print(clientEntIndex, print_chat, "RandPlCount: %d", count);
    for (new i = 0; i < count; i++) {
        client_print(clientEntIndex, print_chat, "RandPl#%d: %d", i, players[i]);
    }
    
    count = GetPlayers(players, "IsPlayerAliveAdmin");
    client_print(clientEntIndex, print_chat, "PlCount: %d", count);
    for (new i = 0; i < count; i++) {
        client_print(clientEntIndex, print_chat, "Pl#%d: %d", i, players[i]);
    }
}

Umm . . . no. First, the function name doesn't describe what the function is actually doing (it doesn't do anything logical). Second, the function will fail relatively often (i.e. return -1). Third, if you want a truly random player, you should do this:

PHP Code:


		
			
stock get_random_player()

{

    new iPlayers[32], iPlayersNum

    get_players(iPlayers, iPlayersNum)

    return iPlayers[random(iPlayersNum)]

}

This will always return a valid player unless there are zero players on the server.
