Well first of all I would like to credit these posts:
How to use it
In the model you will get 4 objects, a ScreenGui, RemoteEvent and 2 Scripts.
Put the Remote event in ReplicatedStorage, the 2 scripts in ServerScriptService and the ScreenGui in ServerStorage.
One of the scripts is named âGiveGuiâ in it you will see a table like this:
local PlayersToGive = {
"SpacialEthanRB";
}
Inside of the table add you and anyone else you want to get the Fake Chat gui.
If you want everyone to get it disable or delete the âGiveGuiâ script and put the FakeChatGui in StarterGui.
If there are any problems tell me.
A few things I want to say:
I am fairly new to scripting.
You could probably do this better.
Sorry if this already exists(I couldnt find one that does).
Also I am not that good a ui design, feel free to change it.
Thanks for reading and I hope you find use for this.
Oh then my bad! Thought it was something you could not use to chat with other players. So basically itâs like the messaging system inside of Rocitizens?
This is pretty awesome This can be used for like a cool YouTube video or something similar to that⌠Can you make it so every player that joins the game can do this, because I was thinking about making a game with something along the lines of the players can control each others chat, similar to what some admin commands can do
Oh ok thank you, sorry I just browsed through the post instead of fully reading it all the way! Thanks for this awesome resource, and big thanks for contributing something very useful to the community; best wishes, MrSavage261
But why would anyone want to do that? I know some games force players to chat in dialogue or other situations but this doesnât seem to be that, this just looks like something to be used for trolling people, which again, I donât see why any developer would want to do that
I mean to make people chat there is a RemoteEvent in ReplicatedStorage called SayChatRequest(im %100 sure its not called like that but it was something like that) when you fire it in the player it will chat for you so im asking did you use that method or some tricky method like creating a message then copying it for all players
Fair warning: impersonating users and speaking for them can result in moderation action depending on what youâre saying, because you could be giving someone else a bad reputation.
I do not recommend using this resource. Speaking for other players should only be done by the server and for an absolutely necessary use case (there really isnât any use case in which itâd be necessary to be completely honest), it should never be able to be done by a client like this.
