Namespaces

Tour of Namespaces - GameDevHQ

Understand how namespaces organize C# code in Unity by grouping related functionality.

Review how GameDevHQ organizes and uses namespaces across its Unity projects.

In this project, you will learn about namespaces. These enable programmers to organise and maintain code correctly, segmenting functionality into libraries if needed.

Check your understanding of the skills and concepts covered in Unit 1 of the course.

Quiz 1

In this Unit, you will be introduced to the course, then you will download and install the Unity software. You will then you will program a car moving side-to-side on a floating road, trying to avoid (or hit) obstacles in the way. In addition to becoming familiar with the Unity editor and workflow, you will learn how to create new C# scripts and do some simple programming. By the end of the Unit, you will be able to call basic functions, then declare and tweak new variables to modify the results of those functions. 

Create with Code - Unit 1 - Getting Started and Player Control

Create a new prototype project and script side-to-side player movement that stays within the play area using if-then logic.

Implement a projectile prefab launched with the spacebar and add boundaries that remove projectiles and animals leaving the game area.

Learn to script a spawner that creates random animal prefabs at the top of the screen when the user presses the S key.

Configure timed spawning, collisions, and a Game Over state while practicing test scripts to improve QA skills.

Practice arrays, randomization, collision detection, and bug reporting by coding a dog that catches falling balls before they land.

Build a starter Unity project using primitive GameObjects and simple materials with a clear camera setup.

Use this quiz to check your understanding of the skills and concepts presented in Unit 2.

Quiz 2

In this Unit, 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. 

Create with Code - Unit 2 - Basic Gameplay

This introductory video previews Unit 3, where you implement Animation, audio, and particle effects in Unity.

Build a simple runner prototype where a player character jumps over spawning obstacles using a spacebar-controlled setup.

Implement a looping background, obstacle cleanup, and collision-based game over using script communication in your runner game.

Animate your character’s running, jumping, and death states with an Animator Controller and sync their timing to gameplay.

Add sound and particle effects to character actions and use exploratory testing to evaluate your prototype.

Troubleshoot a physics-based balloon game with scrolling backgrounds, timed spawns, effects, and detailed bug reporting.

Program constrained player movement based on input and begin applying unit testing to validate your code.

Use this quiz to check your understanding of the skills and concepts covered in Unit 3.

Quiz 3

In this Unit, 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.  

Create with Code - Unit 3: Sounds & Effects

Quiz 4

Get an overview of Unit 4, where you will start implementing new gameplay mechanics.

Build a prototype where the camera orbits an island and a textured sphere moves forward or backward with player input.

Create a textured enemy sphere that spawns randomly, chases the player, and can knock them off the island.

Create a randomly spawning powerup that temporarily boosts player strength and visually indicates its active state.

Build a wave-based Spawn Manager that increases enemy counts and spawns a powerup each wave to intensify gameplay.

Test and fix a soccer-based prototype by applying QA skills to enemy waves, powerups, and scoring behavior.

Configure non-player objects with movement, collisions, prefabs, and spawning to establish your game’s core gameplay.

Check your understanding of the skills and concepts covered in Unit 4 with this quiz.

In this Unit, 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.

Quiz 5

This intro video for Unit 5 outlines what you will do to design and implement a user interface in Unity.

Build a 2D project where good and bad targets spawn with random motion and are destroyed when the player clicks them or they exit the screen.

Add a scoring UI, assign point values to targets, and trigger particle explosions when objects are destroyed on click.

Create Game Over text and a Restart Game button that stop spawning targets, reset the score, and let users replay the game.

Finish your game by designing a title menu with difficulty buttons that adjust how quickly targets spawn.

Debug a whack-a-mole-style UI game by fixing buttons, clicks, scoring, difficulty, and restart behavior.

Replace placeholder primitives with 3D models from the course library or Unity Asset Store and functionally test that gameplay still behaves as designed.

Use this quiz to check your understanding of the skills and concepts from Unit 5.

In this Unit, 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.
