OTClient problem with receive opcodes

Tibia Idle said:

I can’t receive the opcode from the server in OTClient, please help. This is what my code looks like. In the OTClient console it of course displays “OPCODE MODULE START,” but the second message about receiving the opcode doesn’t appear.

on otclient:

LUA:

function init()
    print("OPCODE MODULE START")


    ProtocolGame.registerExtendedOpcode(90, opcoderead)
end


function opcoderead(protocol, opcode, buffer)

    print("opcode from server")

end

on tfs

Code:

function onSay(player, words, param)

        player:sendExtendedOpcode(90, "Test opcode")


    return true
end

looks good to me

the problem is not solved. why my otcleint does not respond to the received opcode?

features.lua enable opcodes here

you mean you sending something to the server?

OtClient
g_game.sendExtendedOpcode(opcode, data)

and handling is in fuction
void ProtocolGame:arseExtendedOpcode(NetworkMessage& msg)

Did you add JSON support to the data/lib folder? And did you enable the opcodes via OTClient, specifically in data/modules/game_feature/feature.lua? If not, you need to add JSON support so that both opcodes work properly. Alternatively, you can use Kondra's OTC detection system, which also works well with JSON. Also, you didn't mention the version of your TFS and its mechanics.

If you don't have JSON, just download Oen's JSON library and add it to your server

OTCv8 detection

Thank you all for the help. Now everything is clear.
