C++ Get all friend list names

[katumblo]

I was in need of a function that returns all the names of the people that are saved in the friend list of player X

I would probably have to change in the source, could someone help me?

Acutally i'm using this tfs: Release OTX Server 2.15 :: Version "SNAPSHOT" · mattyx14/otxserver (https://github.com/mattyx14/otxserver/releases/tag/otxv2_15)
based in The Forgotten Server 0.3.7

List will be always up to date regardless if player has been saved or not

C++ (luascript.cpp)

//getPlayerVipList(cid)
lua_register(m_luaState, "getPlayerVipList", LuaInterface::luaGetPlayerVipList);

int32_t LuaInterface::luaGetPlayerVipList(lua_State* L)
{
    //getPlayerVipList(cid)
    ScriptEnviroment* env = getEnv();
    if (Player* player = env->getPlayerByUID(popNumber(L)))
    {
        int32_t i = 1;
        lua_newtable(L);

        for (uint32_t playerEntry : player->VIPList)
        {
            lua_pushnumber(L, i++);
            lua_pushnumber(L, playerEntry);
            pushTable(L);
        }
    }
    else
    {
        errorEx(getError(LUA_ERROR_PLAYER_NOT_FOUND));
        lua_pushboolean(L, false);
    }

    return 1;
}

C++ (luascript.h)

static int32_t luaGetPlayerVipList(lua_State* L);

Lua (data/libs/050-function.lua)

function getVipListNames(cid, sort, externalQuery)

    local names = {}
    local pending = {}
    local list = getPlayerVipList(cid)

    for i, pid in ipairs(list) do
        local player = getPlayerByGUID(pid)
        if player then
            names[#names + 1] = getCreatureName(player)
        else
            -- # offline players
            if not externalQuery then
                -- # players names are cached in memory once they logged in, othewise a query is executed
                -- # still I recommend to use the external query which fetchs all the data in 1 query
                names[#names + 1] = getPlayerNameByGUID(pid)
            else
                pending[#pending + 1] = pid
            end
        end
    end

    if #pending > 0 then
        local search = db.getResult("SELECT `name` FROM `players` WHERE `id` IN (" .. table.concat(pending, ",") .. ")")
        if search:getID() ~= -1 then
            while true do
                names[#names + 1] = search:getDataString("name")

                if not search:next() then
                    break
                end
            end
            search:free()
        end
    end

    if sort then
        table.sort(names, function(a, b) return a:upper() < b:upper() end)
    end
  
    return names
end

Usage:

    local names = getVipListNames(cid)
    for i = 1, #names do
        print(names[i])
    end

Thats works perfectly!!!

Thank u very much
