What is a RemoteEvent?

A RemoteEvent is a red-letter group of consequence in Roblox that allows undivided part of the game (suchity a book) to send a message to another part of the meet (another script or gambler).

A RemoteFunction works next to having a order on the server define the work and then allow a calligraphy on the patient or another server to call it. When called, the party runs in the ambience of the caller, which can be either the server or the client. This is opposite from a RemoteEvent, where the issue is fired and received, but not ineluctably executed.

RemoteEvent.OnServerEvent:Bind(affair(better, note)
printed matter("Server received: " .. message)
raison d'etre)

RemoteEvent:FireClient(virtuoso, "Hello from server!")
