You wouldnt have too, im just saying if we cant get something like a script to work we could just use an item since it could be simpler to use.
Not really. What you can do is this.
Make a togglable keybind. When activated, it temporarily overwrites all your brick movement keys with the predefined responses. Pressing one of these de-toggles the mode. Pressing the keybind without pressing one of the brick shifting keys also de-toggles it.
Requires a server script and a client script. AND furthermore, if the clients don't have the script, they can't use it, but perhaps they can still see it and/or hear it in the form of text and audio on the server playing to all relevant groups. All not having the client means is that you won't be able to send messages—motivating users to download it when invested.
I know that this is more than a small response, but I've always been against items taking on the role of scripts when purposed toward a more combative use since they take up slots that can be vital or simply take the fun out of it.
