Esta modificação permite que consiga a userdata através do guid

Testado em TFS 1.x

luascripts.cpp

// Player
int LuaScriptInterface::luaPlayerCreate(lua_State* L)
{
    // Player(id or name or userdata or guid)
    Player* player;
    if (isNumber(L, 2)) {
        player = g_game.getPlayerByID(getNumber<uint32_t>(L, 2));
        if (!player) {
            player = g_game.getPlayerByGUID(getNumber<uint32_t>(L, 2));  
        }

Abraço!
