TypeScript for Pac-Man
This TypeScript implementation of the classic arcade game Pac-Man aims to illustrate core concepts and best practices. The codebase adheres to the following principles:
1. Type Safety: Leveraging TypeScript’s type system to ensure code correctness and maintainability.
- Explicit Types: Defining types for variables, parameters, and return values.
- Interfaces: Defining contracts for objects and functions.
- Generics: Creating reusable components and algorithms adaptable to different types.
2. Modular Design: Dividing the codebase into cohesive, well-defined modules.
- Classes: Encapsulating data and behavior within distinct entities.
- Modules: Organizing code into logical units for better maintainability.
- Namespaces: Creating logical groups for related code.
3. Game Logic Implementation: Implementing the core game mechanics, including:
- Game State: Managing the current game state (e.g., player positions, score, level, etc.).
- Movement: Handling player and ghost movement.
- Collision Detection: Detecting collisions between game entities.
- Scoring: Tracking the player’s score and level progression.
Example: The Game
Class
// game.ts
class Game {
// ... (other properties and methods)
private _level: number;
public get level(): number {
return this._level;
}
public set level(value: number) {
this._level = value;
}
}
Explanation:
- Type Safety: The
level
property is explicitly typed asnumber
and the setter method enforces this type constraint. - Encapsulation: The private
_level
property is accessible only through theget
andset
methods, enforcing data encapsulation.
