The following code is supposed to check if a message starts with “:” then if it does, delete the message.

local module = require(game.Chat.ChatScript.ChatMain.ChatChannel)

game.Players.PlayerAdded:Connect(function(player)
	player.Chatted:Connect(function(speaker, recipient, message)
		if string.sub(message, 1, 1) == ":" then
			module.methods:RemoveMessage(message)
		end
	end)
end)

It currently gives the error

 invalid argument #1 to 'sub' (string expected, got nil)

Chatted only gives message and the deprecated recipient as the last parameter. Delete speaker and recipient from your function.

Nope, still doesn’t work.

This time it gave the error:

attempt to index nil with 'RemoveMessage'

How do you delete a chat message?

There’s an error with the module, whereas the code above is working fine. I’m assuming you don’t want the message to be delivered, therefore, you could use

Chat:RegisterChatCallback("OnServerReceivingMessage", function(message)
    message.ShouldDeliver = false 
    return message
end)

instead.

In the chat script? or the module script?

Replace with:

			module.methods:RemoveMessage(message)

Tysm!!! :smiley: :smiley:

I found a pretty easy way to do this.

game.Chat:RegisterChatCallback("OnServerReceivingMessage", function(message)
	message.ShouldDeliver = string.sub(message.Message,1,1) ~= prefix
	return message
end)

Someone already said that. Also, I already found a solution…
