Implement a dynamic camera

Add game audio

Create 2D particle effects

Get started with hand-drawn animation

Build and share your game

You’ve created a functional 2D adventure game, but it’s not finished yet. In this unit, you’ll enhance the overall player experience with a dynamic camera, game audio, and visual effects. You’ll then build your game.

Configure your game to be frame rate independent.

Player character and movement

An engaging world to explore is a critical aspect of your 2D adventure game. In this unit, you’ll take your tilemap from placeholder to fully-realized game environment and implement basic physics so the player character can begin to interact with it.

Game environment and physics

Health is the key stat that players need to keep track of in your game. In this unit, you’ll set up a functional health system and configure objects to increase and decrease the player character’s health.

Health system

You’ve set up a health system, but at the moment the player has no way to know what their character’s health actually is. In this unit unit, you’ll create a heads-up display (HUD) interface and configure it to show the player character’s health level.

Heads-up UI display

In this unit you’ll work on adding enemies and interaction mechanics to bring your game to life. 

By the end of the unit, you’ll do the following:

Implement projectiles to attack the enemies.

Add a friendly NPC to share a message with the player character.

Characters and interaction mechanics

 Next steps

Now that you’ve created your own complete game, create a build to share it with your community.

You’ve created a game, and now you’re ready to share it with others — perhaps you want to get playtest feedback or perhaps you want to publish your game for the wider world! To do this you need to create a build — a standalone, playable version of your game. This tutorial will guide you through making a computer build for Windows, macOS, or Linux. 

By the end of this tutorial, you’ll create a shareable build of your game. We’ll also share some further resources to help you continue your 2D learning journey.

Note: If you want to make an online playable build that you can publish on Unity Play or other sites like itch.io, you can find specific guidance in Create and publish WebGL builds.

This tutorial is part of Beginner 2D: Adventure Game, but the guidance in this tutorial is relevant for any beginner who wants to create a computer build of their real-time experience.

Note: For the purposes of this tutorial, we chose to use the Ruby’s Adventure asset set, and the file paths used in instructions will reflect this. If you chose another asset set, the file names will  be the same, but in your corresponding theme folder. 

Before you can create a build of your game for a particular platform, you need to add the Build Support module for that platform to your Unity installation. You may have already done added the module at the point of installing the current LTS version of Unity, but if not then add one of the following modules now:

To install the relevant module for the build that you want to create, follow these instructions.

1.  Open your project in the Unity Editor.

2.  In the main menu, go to Edit > Project Settings…, then select Player.

3.  At the top of the settings list, you can add the following details for your game:

4.  Further down the list, find the Settings for Windows, Mac, Linux section. Use the foldout (triangle) to expand the Resolution and Presentation section. You don’t need to make any changes here, but if you want to then you can review the options available in the following platform-specific documentation:

To configure and create the build for your game, follow these instructions:

1.  In the main menu, go to File > Build Settings….

2.  Below the Scenes in Build list, select Add Open Scenes. The scene that you have created your game in will be added to the list. 

3.  If there are any other scenes listed, such as an example scene from the project files, right-click its listing and select Remove Selection.

Note: If you are working with your own project you may have multiple scenes that you want to include in the build. Make sure that they are all added here — you can drag scene assets from the Project window and release them over the Scenes in Build list.

4.  In the Platform section, confirm that Windows, Mac, Linux is selected.

5.  Set Target Platform to your chosen build platform.

7.  In the dialog, enter a name for your build and create a new folder named “Builds” to contain it, then select Save. Unity then compresses the assets, compiles the scripts, and does everything else necessary to create the executable file. When this process is complete, the Builds folder will open.

8.  If you have created a build for the platform you are currently using, double-click the executable file to launch your game. Share this file so others can play your game!

Note: Your Beginner 2D adventure game has no menu or exit functionality. If you run the game in fullscreen, use the following shortcut to end the game:

You have now created your own 2D adventure game from scratch and created a playable version to share with your community! That’s a huge achievement. Here are some additional resources to help you continue your learning journey with Unity:
