I dont know why i didnt answer the same day, but i found also way to catch emessage_ with orpheu:
Code:
..OrpheuGetEngineFunction("pfnWriteString","WriteString")
OrpheuRegisterHook(WriteString,"WriteStringf",OrpheuHookPre)
so its only one argument (string[]), which is a little easier compared to register_message, thanks ofc @OciXCrom !
PS: Why colorchat didnt include already emessage_* , but only message_* ? I mean, there must be any downside of using emessage then ?
