RemoteEvent/OnClientEvent|OnClientEvent to be fired in
LocalScripts running for the given
Player. Additional data passed to this function is then provided to OnClientEvent; beware of limitations on this data.
Since this function is used for communication from server to client, so it will only work when used by a server-side
Script. For client-to-server communication (the other direction), use
RemoteEvent/FireServer|FireServer. Direct client-to-client communication not possible on Roblox; however, it can be simulated using a
Script that relays information received through some other means, such as
RemoteEvent/FireAllClients|FireAllClients, which works similarly but for all
Remote Functions and Events, which describes related classes, functions and events and also important limitations on the data that can be sent
Sometimes a game will need to send information from one client to another. Roblox does not support direct client to client contact, so any communication must first go through the server. This is typically done using remote events (although functions could be used if desired). First, the sending client would call FireServer. On the server, the function connected to OnServerEvent would hear this firing, and itself would then call FireClient.
The arguments passed to the
RemoteEvents: Server to a Single Client
The server can send messages to the client through remote events in two ways: it can send a message to an individual client or it can send a message to every client at the same time.
In order to send a message to a single client, the FireClient function should be called from the server via a
To listen for the message on the client, a
LocalScript needs to connect a function to the OnClientEvent event of the RemoteEvent.
