A very nice and well explained tutorial, i just added a simple UI just for fun, then my recording can't handle the game properly. So its laggy but while playing it no, its not.

Create a build of your game for Windows or macOS

Identify the next steps in your personal learning journey

Note: Linux support is currently in preview, and not fully supported. The steps to build for Linux should be broadly parallel to those for Windows; if you encounter a bug, please report it to the team. 

Unit 2 - Program a basic game

By the end of this tutorial, your game will look something like this:

Follow the video or text instructions below to configure your build settings, configure your player settings, build your game, and finally play your standalone game:

To open the Build Settings window, from the main menu go to File > Build Settings. Alternatively, you can press Shift+Control+B (macOS: Shift+Cmd+B). 

Select Windows, Mac, Linux in the Target Platform box, 

In Scenes in Build, select Add Open Scenes to add your Roll-a-ball game to the build. You can also drag scenes from the Project window to this list. 

If SampleScene is showing in the list, disable it to exclude it from your build.


Select Player Settings to open a range of different configuration options for the Game view. 

If you want, change the Company Name, Product Name, and Version.

Select Resolution and Presentation and change the Fullscreen Mode box to Windowed.

By default this will have a resolution of 1024 by 768, but set the default width and height to something smaller if your screen uses a lower resolution.

Close the Project Settings window and return to the Build Settings window.


Select Build. This will bring up a dialog that asks you to choose a build location. 

To keep things tidy, create a new folder inside your project called “Builds” at the root of the project, alongside the Assets and Library folders.  

If you’re using macOS, you can also choose a name for your build.

Confirm that you want to Select Folder (Windows) or Save (macOS). Unity will now build the application and save it to the Builds folder.


Navigate to the Builds folder and then run the executable application.

Note: When building for macOS, Unity builds an .app bundle that contains all of the relevant data and files. When building for Windows, Unity builds an .exe file and a data folder that contains all of the necessary resources. 

The Build Settings window with the Add Open Scenes and Player Settings buttons highlighted. In the Player Settings window, the FullScreen mode is set to Windowed.

After you’ve finished your project, what will you do next? Consider some of the options below:

If you are not already confident with your programming, it is recommended that you start with Create with Code or the more comprehensive Junior Programmer Pathway, which will take your programming skills to the next level. You can also check out the Creator Kit: Beginner Code project!


You did a bit of design in this project, but there is an entire Creative Core pathway that will take you through the fundamentals of materials, visual effects, lighting, post-processing, audio, user interface design, and more.


If you want to continue down the games path, Unity Learn has a wide range of games-based learning content, including the following: 

If you went above and beyond and created your own take on the Roll-a-ball game, take a screenshot or screen-recording and post it here to share what you made! To upload your project online as a WebGL build so others can play it, you can:

Follow the instructions to create and build your project for WebGL.
