How do you prevent two callbacks when using OnIncomingMessage?

I’m currently attempting to learn the new chat system, and I want to use OnIncomingMessage as it’s much more reliable for certain situations compared to MessageReceived.

What do you mean by “two callbacks”? OnIncomingMessage is a property, not a connection of some kind, which means it can only hold one value at a time. Therefore, the latest callback you assign will be the one it uses.

That’s happening because the callback is triggered when the TextChatMessage’s Status is either Sending or Success, so you can use an if statement to check whether the message’s status is the relevant one for your needs

Example code:

local TextChatService = game:GetService("TextChatService")


local function onIncomingMessage(message: TextChatMessage)
	if message.Status == Enum.TextChatMessageStatus.Success then
		-- Run your code inside of this if statement
	end
end

TextChatService.OnIncomingMessage = onIncomingMessage

Two call backs meaning, when a message is sent with OnIncomingMessage… fires twice when binded on the client. This causes issues when you want to fire an Event as the event will fire twice. I was originally doing this to create a system where I could turn the chat censor off for certain instances.

Client Functionality: When bound to the client sending a message, this callback is run twice; first when the message is initially sent and received locally, and again when the client receives the result of the filtered message from the server
