Study Notes

Game Engines

Game engines are classified as Open or Closed, depending on whether they are accessible for public use or restricted to the developer studio.
Notable game engines include Frostbite, Panda3D, CryEngine 3, UE4,5, Unity, and Godot.
Unity stands out as a favorite for indie developers, offering a wealth of tools to assist in game development.

Game Design Basics

A Game Design Document (GDD) serves as a blueprint for game development, outlining the project's scope and ensuring all team members are aligned.
The GDD is a living document that evolves alongside the game development process.
Important components of a GDD include:
- Game Name: A catchy, memorable name reflecting the game's essence.
- Overview: A concise summary highlighting the game's key features, story, and innovations.
- Target Audience: Identifying the intended player base to inform design decisions.
- Genre: Clearly defined genre, for example, RPG, action-adventure, etc.
- Characters: Introduces main characters and NPCs (Non-Player Characters).
- Story: Delves into the game's setting, backstory, and narrative.
- Gameplay: Outlines the core gameplay mechanics and objectives.
- Game Mechanics: Describes how the player interacts with the game world.
- Art: Covers graphics, storyboard design, and the desired art style.
- Audio: Describes the music and sound effects envisioned for the game.
- Technical Description: Specifies platforms, tools, programming language, and technical aspects of development.
- Marketing Plan: Outlines strategies for reaching target audiences.

Game Genres

Game genres are distinguished by shared gameplay characteristics, creating expectations for players regarding mechanics, themes, and elements.
Game views encompass how the camera is positioned:
- 3D:
  - First Person: View from within the character's perspective.
  - Third Person: View behind the character.
- 2D:
  - Top Down: Overhead view.
  - Side to Side: Lateral view.
- 2.5D:
  - Isometric: View with 120-degree angle intersections.
Major game genres include:
- Action-Adventure: Emphasis on character story and puzzle-solving.
- Puzzle: Focus on logic, observation, and pattern completion.
- RPG (Role-Playing Game): Players assume character roles and interact within a fantasy world.
- MMO (Massively Multiplayer Online): Online games with large player bases.
- Educational: Focus on education through entertainment.
- Sports: Simulation of athletic competitions.
- Shooter: Players engage in combat using projectiles.
- Simulation: Players create and manage virtual worlds or environments.
- Strategy: Players make strategic decisions and plans.
- Horror: Aims to create a frightening experience for the player.
- Battle Royale: Players compete to be the last one standing.

Game Elements and Binary Space Partitioning (BSP)

Game elements are essential components of a game’s world, such as character models, geometry, and terrain.
Binary Space Partitioning (BSP) is a technique frequently used in game development to efficiently manage game environments.
BSP functions by recursively dividing a space into smaller regions using planes or lines, creating a hierarchical tree structure. This structure helps to optimize rendering, collision detection, and other game-related tasks.
Key Steps in BSP:
- Initial Division: The space is initially split into two regions.
- Recursive Subdivision: The split regions are further divided, creating a hierarchical tree.
- BSP Tree Structure: The hierarchical tree represents the subdivided space relationships.
- Handling Objects: BSP efficiently handles objects within the subdivided space.
- Applications: BSP finds use in game rendering, collision detection, pathfinding and level design.
BSP helps to create structured and navigable environments while allowing for random elements to introduce variability.
