Hello all,
Currently, I am working on a small system which, on a basic level, corrects grammar in a game. For example, this adds a period to the end of sentences, alters some specified “phrases” to the preferred option(“u” → “you”, “cant” → “can’t”), and will alter names documented (tom → Tom).
I had successfully completed this with the TextChatService, however this caused some other issues in my game.
So, I’ve moved to using the <Chat>:RegisterChatCallback() function. I am using the OnServerReceiving chatCallbackType and running the script on a ServerScript, located in ServerScriptService.
Something to note, as you can see in my script, I print the “message” object twice. The first time, the “Message” data (found via message.Message) is the uncorrected form and the second print is the corrected form, yet this doesn’t seem to actually apply in-game.
Please can you provide any advice or solutions, it would be appreciated.
