[filhodaputa]

Hello! i need a simple call with lua to know the private channel id...
well i know private channel have a number between 100 and 10000...


where i call this:
in lua

getPlayerChannelId(cid)

in luascript.cpp i do:

int32_t LuaScriptInterface::luagetPlayerChannelId(lua_State* L)
{

    ScriptEnviroment* env = getEnv();

    uint32_t cid = popNumber(L);
                 
    Player* player = env->getPlayerByUID(cid);
      
    if(PrivateChatChannel* channel = g_chat.getChannelidByplayer(player))
    {
        lua_pushnumber(L, channel->getId());
     } else {
           lua_pushboolean(L, false);    
     }}

in chat.cpp i created:

PrivateChatChannel* Chat::getChannelidByplayer(Player* player)
{
    if(!player || player->isRemoved())
        return NULL;

    PrivateChatChannel* channel = NULL;
    for(PrivateChannelMap::iterator it = m_privateChannels.begin(); it != m_privateChannels.end(); ++it)
    {
        if((channel = it->second) && channel->getOwner() == player->getGUID())
            return channel;
           
    }
