Addon message packet structure

[SaiFi0102]

Hi,

I recently started working on a addon-server communication system AIO and I wanted to extend it. However the packet structure is unknown/incorrect in Catacylsm 4.3.4 and my messages were not being handled on the client. I've been trying to reverse engineer to find the packet structure for receiving addon whisper message but I couldn't because the opcode SMSG_MESSAGECHAT(0x2026) was only referenced once and it was an inequality instead of a equality.

Could any one please help me out?

This team has done a lot of work, have a look: https://github.com/TrinityCore/WowPacketParser/

The packet is now known as SMSG_CHAT.

Thanks for replying, however, I fixed the problem. Since there is no working project for WoW 4.3.4 server Ill post here about how I fixed it:

Replace the function Player::BuildPlayerChat(...) with this

void Player::BuildPlayerChat(WorldPacket* data, uint8 msgtype, const std::string& text, uint32 language, const char* addonPrefix /*= NULL*/) const
{
*data << uint8(msgtype);
*data << uint32(language);
*data << uint64(GetGUID());
*data << uint32(0); // constant unknown time
*data << uint64(GetGUID());
if(addonPrefix)
*data << addonPrefix;
*data << uint32(text.length() + 1);
*data << text;
*data << uint8(GetChatTag());
}
