What They Are

• Remote Functions are a way for the client and server to communicate and get a return value.
• Unlike Remote Events (which are one-way), Remote Functions wait for a response.

Key Points

• Only one response is sent per call.
• Can be used to request data from the server or tell the server to return a value.
• They must be stored in ReplicatedStorage or another location accessible to both client and server.

Creating a Remote Function

1. Go to ReplicatedStorage.
2. Insert → RemoteFunction.
3. Give it a name, e.g., GetPlayerData.

Server Script Example

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local GetPlayerData = ReplicatedStorage:WaitForChild("GetPlayerData")

-- Function to handle requests from the client
GetPlayerData.OnServerInvoke = function(player)
    return "Hello, " .. player.Name
end

Client Script Example

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local GetPlayerData = ReplicatedStorage:WaitForChild("GetPlayerData")

-- Call the remote function
local result = GetPlayerData:InvokeServer()
print(result)  -- Output: Hello, PlayerName
