How to hide chat?

I was wondering how to make it so you can hide someones chat if a certain value is true/false. Like in Murder Mystery. I've been trying making my own chat gui, it seems impossible to do how the murder games do it. If the players are dead I don't want the players who are alive to see the deads text.

You can use the SetCoreGuiEnabled method when that value changes. (http://wiki.roblox.com/index.php?title=SetCoreGuiEnabled_(Method))

boolValue.Changed:connect(function(newValue) -- When the BoolValue changes, it will enable/disable chat
	Game.StarterGui:SetCoreGuiEnabled("Chat", newValue); -- Enables/Disables the Chat Core GUI dependong on the newValue
end);
