Go from an empty folder to a playable 3D multiplayer prototype in about 15 minutes. This advanced workflow leverages the Claude command-line interface and parallel development to rapidly build and debug both the frontend and backend of a flight simulator game.

In your terminal, create a new React project using Vite. Then, navigate into the project directory and initialize the Claude CLI using the --yolo flag, which gives the AI permission to make changes without confirmation.
npm create vite@latest your-game-name -- --template react
cd your-game-name
claude init --yoloGive Claude a broad, creative prompt describing the game's core concept, art style, and control scheme. Avoid overly detailed specifications to allow the AI creative freedom to scaffold the entire application, install dependencies, and generate the initial code.
I want to build a flight simulator game that uses three js. Let's use polygon style art for the planes. WSD for movement. I want turning to bank the plane and arrow keys to control pitch. Let's have it take from a green field with trees and other objects around.After the AI finishes its first pass, run the application. Identify any obvious bugs, such as camera placement or inverted controls. Describe these problems to the AI in plain English to have it iterate and fix the code.
It looks like my camera is facing the front of the model... we should be looking should be fixed to the tail of the plane. All of my flight controls are reversed. Now we should fix that. I also want the camera to be slightly above and behind the model.While the first AI instance is fixing the frontend, open a *second* terminal window in the project's root. Create a server directory and task a new instance of the Claude CLI to build the multiplayer backend using Node.js, Express, and Socket.io.
In the second terminal, give the AI a clear prompt for the backend server's functionality. This will trigger the AI to set up a server, integrate WebSockets, and handle the logic for players joining and moving.
I want to start implementing multiplayer for this game in the server directory. Handle player joins and give me a chat interface on the top right that shows when people join the game.Once both AI instances have completed their tasks, launch the server and the frontend application. Open multiple browser tabs to connect to the game and verify that you can see other players' planes in the shared world, demonstrating a working multiplayer prototype.
