unity to wasm

Running Your Unity Game on the Web with Docker Compose

Here’s a quick guide to exporting your Unity game as WebAssembly (Wasm) and setting it up to run on your website using Docker Compose. Let’s dive in!

Step 1: Export Your Unity Game as Wasm

1. Open Your Project: Launch Unity and open your existing game project.
2. Select WebGL Platform: Go to File > Build Settings. In the Build Settings window, select WebGL as your platform.
3. Build the Project: Click Build to generate your game as a WebAssembly build. Unity will create an HTML file, along with .wasm and .data files in the chosen directory.

Step 2: Set Up a Web Server with Docker

To serve your WebAssembly files, we’ll use Nginx as a simple web server.

1. Create a Dockerfile: Place this Dockerfile alongside your build directory.

    FROM nginx:alpine
    COPY ./Build /usr/share/nginx/html
    EXPOSE 80
   

2. Build the Image: Run docker build -t unity-wasm . in your terminal to create a Docker image.

Step 3: Use Docker Compose

We’ll orchestrate our setup using Docker Compose.

1. Create a docker-compose.yml File:

    version: '3'
    services:
      web:
        build: .
        ports:
          - "8080:80"
   

2. Start the Service: Run docker-compose up in your terminal. It will build and launch the Nginx server.

Step 4: View Your Game

• Open a web browser and go to http://localhost:8080 to see your game up and running!

Conclusion

By exporting your Unity game as WebAssembly and using Docker Compose, you’ve set up a web server that can run your game in a consistent, isolated environment. This makes deployment simple and scalable.

Happy gaming, and feel free to share your experiences!
