Study Notes

Game Development Roles

Concept Artist, Media Designer, 3D-Artist, Audio Artist, VFX, SFX, Game Designer, Game Logic Engineer, Level Designer, Engine and Tool Developer, Networking Engineer, Tester, Quality Assurance, Producer, Project Manager, Community Manager, and Product Owner are some of the key roles in game development.

Agile Workflow Models

Scrum and Design Thinking are two common Agile workflow models used in game development.

Game Development Stages

The 7 stages of game development include concept, pre-production, production, testing, launch, maintenance, and support.

Game Loop

A simple game loop involves initializing, updating, and rendering the game state.
A multithreaded game loop involves synchronization challenges.
Unity's game loop involves updating, fixed updating, and rendering.
Other game loop patterns include fixed time step, variable time step, and semi-fixed time step.

Update and Fixed Update

Update is called every frame with a variable delta time.
Fixed Update is called in a fixed interval with a constant delta time.
Fixed Update is important for physics and rendering.

Delta Time

Delta time refers to the time elapsed since the last update call.
Delta time is used to update scenery based on the elapsed time.

Asset Handling

Game assets include graphics, audio, and sound effects.
Asset handling involves loading, processing, and rendering assets.
Always ensure you own the rights to an asset before using it in your game.

Audio

Audio assets include background music and sound effects.
Audio implementation involves 2D and 3D audio.
2D audio is used for background music and instructions, while 3D audio is used for spatial position and movement.

Rendering

Rendering is the process of converting geometric objects into a visual image.
The graphics pipeline involves feeding in polygon vertices, color information, bitmaps, and light locations, and outputting a rendered 2D image.
Real-time rendering has evolved from its early days in 1958 to the current state of the art in UE5.
The main difference between 2D and 3D render pipelines is the addition of projection and other steps in the 3D pipeline.

Physics and Collision Detection

Physics involves updating objects based on forces and acceleration.
Collision detection involves testing for intersection between objects.
Pixel-based collision detection is a simple but time-consuming method used for mouse hit testing in 2D games.
