Mini-mission

A Script can use RunContext Server or Client. A LocalScript runs on the client in supported locations; a LocalScript placed in ReplicatedStorage does not run simply because it is visible there.

This exercise uses an explicit server Script in ServerScriptService and a LocalScript in StarterPlayerScripts. The latter is copied into each player’s PlayerScripts.

Your task

Add both files below. The server prints Server ready and true; each client prints Client ready and its own player name.

Interface: Complete the documented Studio hierarchy and self-check the behavior outside the browser.

Input	Expected

See another example

local RunService = game:GetService("RunService")
print("Server?", RunService:IsServer())

IsServer reports the execution context rather than the name or location you hoped to use.

Your explanation

Self-check rubric

The server prints once per server session.
Each client prints its own name.
Move the LocalScript to ReplicatedStorage temporarily; observe that this placement does not run it. Restore the correct location.

Your explanation is a self-check. Exact wording is not automatically graded.

Self-checked Studio exercise. A saved checklist records your own review; no uploaded place file or screenshot is executed here.

Build this hierarchy

ServerScriptService
  ContextServer (Script, RunContext=Server)
StarterPlayer
  StarterPlayerScripts
    ContextClient (LocalScript)

Create the two script types in the exact locations.
Use Studio Test with one server and two clients.

ServerScriptService/ContextServer.server.luau

Server entry point; set RunContext Server.

local RunService = game:GetService("RunService")
print("Server ready", RunService:IsServer())

StarterPlayer/StarterPlayerScripts/ContextClient.client.luau

LocalScript runs independently on each client.

local Players = game:GetService("Players")
print("Client ready", Players.LocalPlayer.Name)

Expected output

Server Output: Server ready true.
Each client Output: Client ready followed by that client’s player name.

Studio assessment checklist

The server prints once per server session.Each client prints its own name.Move the LocalScript to ReplicatedStorage temporarily; observe that this placement does not run it. Restore the correct location.

Multiplayer tests

Run one server and two clients and compare the three Output views.

Troubleshooting and production considerations

LocalPlayer is nil on the server. Put that code in the client file.

Set the server Script RunContext explicitly; do not infer it from a filename.

Explain more

A Script can use RunContext Server or Client. A LocalScript runs on the client in supported locations; a LocalScript placed in ReplicatedStorage does not run simply because it is visible there.

This exercise uses an explicit server Script in ServerScriptService and a LocalScript in StarterPlayerScripts. The latter is copied into each player’s PlayerScripts.

Use server and client Output views to observe context. Seeing the same message twice is not evidence of a shared authoritative state.
