How to Use These Scripts in Build a Plane (Roblox)

1. Install Roblox Studio

First, ensure you have Roblox Studio installed. This is the official development environment for creating and testing Roblox games.

🔗 Download Roblox Studio

• Either open your existing “Build a Plane” game or create a new Baseplate template.

3. Insert a Script Object

• Right-click on the object you want the script to control (e.g., a plane model).
• Choose Insert Object → Script.
• Paste the desired script code into the script editor.

4. Adjust Parameters

Many scripts include customizable values like speed, lift, fuel, or colors. Adjust these to suit your plane’s design.

5. Test in Play Mode

• Click Play or F5 to enter test mode.
• Make sure your scripts are working as expected (e.g., the plane takes off, fuel depletes, camera follows).

6. Fix Errors If Any

Check the output panel for any red error messages. If needed, tweak your Lua syntax or object references.

7. Publish Your Game

Once all scripts are in place and working:

• Go to File → Publish to Roblox As…
• Fill in your game’s name, description, and settings.
