Publish for web and mobile

Add mobile controls and publish your game to Unity Play.

Publishing a Unity project lets you share your game on different platforms, like mobile and web. Each platform has unique challenges, such as adapting controls for touchscreens and optimizing performance.

In this tutorial, you'll configure your project for WebGL and mobile so that anyone with the link can play your game on their computer, phone, or tablet. You'll integrate mobile-friendly controls, adjust build settings, create a build, and publish your game to 

Overview

When publishing a game for both desktop and mobile, you need to consider input differences. On desktop, players use a keyboard and mouse, but mobile users rely on touch controls. In this step, you'll add a 

 prefab, which provides an on-screen joystick and fire button for touch input. A custom script will automatically detect whether the game is running on a mobile device, then show or hide these controls accordingly.

You might have already realized that local multiplayer will not be possible on a mobile device — it would be pretty hard for two people to both control separate tanks on a single screen! There’s some code on the Player Selection screen that detects if a mobile device is being used, and if so, prevents a P2 option from being selected on the Player Selection screen.

Enter Play mode and notice that the mobile UI elements disappear when testing in the Unity Editor, then exit Play mode.

Enter Play mode again to test the mobile controls using your mouse.

 movement system, where the tanks move in the direction you drag, rather than using a fixed forward direction.

 so the UI will properly hide on non-mobile devices.

Your game now includes mobile-friendly controls that dynamically appear only when needed.


Add mobile controls

 packages your Unity project into a playable version that can run on a specific platform. To ensure that all necessary content is included, you must select the scenes that should be part of the final build. In this step, you'll add your game scene to the Build Profile so Unity knows to include it when creating the final playable version.

If there are any scenes already present in the

Your game scene is now properly added to the build, ensuring it is included when you generate a playable version. Also, when your game loop is complete, the 

 scene will be reloaded after finishing the rounds.

Configure the scenes in the build

Unity allows you to publish a single project to many different platforms, including mobile, console, desktop, web, and more. To publish your project to the web, you first need to switch to that platform.

Switch to the Web platform

Now that you've switched platforms, you can create a build of your project. 

 is a packaged, playable version of your game that you create when you want people to play it outside the Unity Editor.

This will open a file explorer asking you where you want to save your build. 

: To stay organized, first, make a new folder named something like “Web Builds”, and open it.

Enter a name for your build, such as "[YourFirstName] Tanks build", then select 

This first time your project builds can take up to ten minutes. Subsequent builds will not take as long.

When the process is complete, the folder containing your build will appear. Keep that folder open, you’ll need it in the next step. 

Build your project

With your build complete, you're ready to publish it to 

, allowing you to play your project online and easily share it with others.

On Windows, right-click the folder and select 

This will create a new .zip file that you can upload to Unity Play.

Drag and drop your zip file onto the upload area and wait for it to process. 

 to ensure it works correctly on mobile devices.

Your game is now live on Unity Play, making it accessible for others to play and test!


Publish to Unity Play

Now that your game is published, it’s time to try it out! This is your chance to see how well everything works, from controls to performance, and make any final tweaks before sharing it with others.

Play your game on Unity Play, making sure movement, actions, and UI elements work as expected.

Copy the game’s Unity Play link and send it to yourself via email, messaging app, or notes app.

Open the link on a mobile browser (such as Chrome or Safari).

Check that the on-screen joystick and action button appear and function correctly.

If you spot anything you want to improve, simply follow the instructions above to rebuild and re-publish your game.

The tutorial after this one will give you some ideas and guidance for adding new, fun features to your game, too.The Unity Play link remains the same, so you won’t need to resend it after updating.

Congratulations! Your game is now live and working across multiple platforms! 


Test your game on different devices
