How to Use RemoteEvents (for dummies) - Roblox Studio

How to Use RemoteEvents in Roblox Studio

1. Create a New RemoteEvent:

   • In Roblox Studio, click on "New" and select "RemoteEvent."
   • Keep the default name for now. A RemoteEvent allows passing data between the server and client in Roblox.

2. Understand the Difference between Server and Client:

   • The server is what every player sees in the game, while the client is what each individual player sees.
   • Changes made on the client-side, like color changes, are only visible to the player who triggers them.

3. Set Up the Scene:

   • Create a red part and place it in the workspace.
   • Add a RemoteEvent in ReplicatedStorage.

4. Create an Event Script:

   • Add a new script and name it "EventScript."
   • Leave the script empty for now.

5. Add a Button:

   • In StarterGui, add a TextButton or ImageButton.
   • Attach a LocalScript to the button.

6. Trigger Color Change:

   • When the button is pressed, we want the color of the part to change.
   • Use the following code in the LocalScript attached to the button:

     script.Parent.MouseButton1Click:Connect(function()
         game.ReplicatedStorage.RemoteEvent:FireServer()
     end)
     

7. Update Color on the Server:

   • In a server script, listen for the RemoteEvent trigger:

     game.ReplicatedStorage.RemoteEvent.OnServerEvent:Connect(function(player)
         workspace.Part.Color = Color3.new(0, 0, 1)  -- Change color to blue
         print(player.Name)  -- Print the player's name
         wait(5)  -- Wait for 5 seconds
         workspace.Part.Color = Color3.new(1, 0, 0)  -- Change color back to red
     end)
     

8. Testing the Setup:

   • Press the button in the game.
   • Check if the color changes to blue and then back to red after 5 seconds on the client side.

9. Understanding RemoteEvents:

   • RemoteEvents allow communication between the client and server in Roblox.
   • By using RemoteEvents, you can trigger actions on the server based on client interactions.

10. Challenge:

    • Modify the script to make the color change back to red after 5 seconds only on the client side while the server still sees it as blue.

By following these steps, you can effectively use RemoteEvents in Roblox Studio to create interactive gameplay experiences.
