In this Mission, you will program a top-down game with the objective of throwing food to hungry animals - who are stampeding towards you - before they can run past you. In order to do this, you will become much more familiar with some of the most important programming and Unity concepts, including if-then statements, random value generation, arrays, collision detection, prefabs, and instantiation. In completing this Unit, you will learn how to program a basic game with the ability to launch projectiles and maneuver the player to keep the game alive.

Learn how to add music, sound effects, and visual particle effects to transform the experience of your project.

In this Mission, you will program a fast-paced endless side-scrolling runner game where the player needs to time jumps over oncoming obstacles to avoid crashing. In creating this prototype, you will learn how to add music and sound effects, completely transforming the experience of your projects. You will also learn how to create dynamic endless repeating backgrounds, which are critical for any side-scrolling games. Finally, you will learn to incorporate particle effects like splatters and explosions, which make your games so much more satisfying to play.

Quiz 4

Learn how to implement new gameplay mechanics including powerups and increasing difficulty.

In this Mission, you will program an arcade-style Sumo battle with the objective of knocking increasingly difficult waves of enemies off of a floating island, using power ups to help defeat them. In creating this prototype, you will learn how to implement new gameplay mechanics into your projects, which are new rules or systems that make the game more interesting to play. On one hand, you will learn to program a powerup, which give the player a temporary advantage. On the other hand, you will learn to program increasingly difficult enemy waves, which make survival more challenging for the player. A good balance of powerups and increasing difficulty make for a much more interesting gameplay experience.

Introduction to user feedback and testing

Learn how to implement a User Interface - or UI - into your projects, such as a title screen and score display.

In this Mission, you will program a game to test the player’s reflexes, where the goal is to click and destroy objects randomly tossed in the air before they can fall off the screen. In creating this prototype, you will learn how to implement a User Interface - or UI - into your projects. You will add a title screen with a difficulty select menu that will control how challenging the gameplay is, you will add a score display that will track how many points the player has earned, and you will add a Game Over screen, which will allow the player to restart and try again. In learning these skills, you will be able to create a fully “playable” experience that the user can enjoy from start to finish without having to restart the application to try it again.

Principles of object-oriented programming

Create a scene flow

Implement data persistence between scenes

Implement data persistence between sessions

Quiz: Manage scene flow and data

Submission: Data persistence in a new repo

Learn about data persistence and an introduction to the core pillars of object-oriented programming.

In this mission, you’ll learn about data persistence, or how to manage the loading and unloading of data between both scenes and sessions. Along the way, you will be introduced to the core pillars of object-oriented programming, which will help you structure your code throughout the mission. There will only be one practical example throughout the mission, which will build on the new functionality you create with each tutorial. At the end of this mission, you’ll take everything you learned and apply it to a new project by building a persistent score system for a small game.

Manage Scene Flow and Data

Abstraction in object-oriented programming

Inheritance and polymorphism in object-oriented programming

Encapsulation in object-oriented programming

Profile code to identify issues

Job preparation: Junior Programmer

Quiz: Apply object-oriented principles

Submission: Programming theory in action

Deep-dive into the pillars of object-oriented programming and their application, then learn how to profile and optimize code.

In this mission, you’ll refactor the inventory project you completed in the previous mission using the pillars of object-oriented programming as a guide. You’ll deep dive into the inner workings of each pillar individually, so you can better understand its value in developing applications. Next, you’ll learn how to profile your code to identify any optimization bottlenecks that would slow down the final build of your application. To close out this mission, you’ll develop a small application for your portfolio that uses fully optimized code built on OOP principles. 

When you complete this mission you will complete the Junior Programmer pathway - CONGRATULATIONS!

ErrorProject.zip

As a programmer, you’re going to spend a lot of time debugging code. By debugging your scripts on a regular basis, you’ll improve your code comprehension and be able to anticipate problems during the development process. In this challenge, you’ll be tasked with debugging an existing project and making it run as intended. 

To begin this challenge, you must first download the challenge assets and import them into a new Unity project:

2.  To unzip the contents of the folder, right-click the folder and select Extract All (macOS: double-click the zipped folder). Inside you will find ErrorProject.unitypackage.

Note: While it is possible to view the contents of a folder while it’s still zipped, the data is still compressed. Attempting to import the contents of the Error Project folder while it’s still zipped will result in an error message in Unity. Ensure that you have unzipped the folder before proceeding to the next step.

3.  Create a new Unity project using the 3D template —  remember to use one of the supported versions of Unity, such as 2022.3 LTS or 6000.0 LTS.

4. Import ErrorProject.unitypackage into your new 3D template project. 

Before you begin debugging the project, take a few minutes to learn all you can about it. As soon as you import the .unitypackage, you’ll see two error messages appear in the Console window. These errors will prevent you from testing the scene, so try to determine what the project does based on the contents of the Hierarchy in the included scene and the script attached to the TextDisplay object. 

Once you feel confident that you understand what the app is trying to do, make changes to the scene and script as needed so that the code compiles and you’re able to test the scene. What you see in the Game view should make it clear whether or not your application is fully fixed. 

Once your app is fully functioning, you will create a WebGL build of your project, upload it to Unity Play, and then complete this challenge by linking your submission below. To do so:

2.  Ensure that your version of Unity has the WebGL module installed. 

3.  Install the WebGL Publisher package. This package will allow you to easily publish your project on Unity Play. If you aren’t sure if you have the package or don’t know how to add it, refer to this tutorial.

4.  Select File > Build Profiles from the main menu. Under the Platforms section, select Web, then select the Switch Platform button and wait until the process finishes.

5.  Create a WebGL build of your project. This may take a few minutes, depending on your computer. If you need help creating the build, refer to step 3 of Getting started with Unity Web.

6.  Publish your WebGL build on Unity Play. 

7.  Copy your Unity Play link, and paste it below! 

You’ll know you’re successful if you’ve met these criteria:


There are no errors or warnings present in the Editor console.

You are able to press Play in the Editor and see the active scene.

You have created a WebGL build of your project.

You have uploaded the WebGL build to Unity Play.

You’ve copied your Unity Play link for submission.

Congratulations on completing the second mission in the Junior Programmer learning pathway. After completing the final quiz, you will have acquired all of the skills needed to take the Unity Certified User: Programmer certification exam.
