Customizing GameEntity and GamePlayerEntity Classes

In TypeScript development, directly extending or modifying global classes (such as GameEntity and GamePlayerEntity) can introduce potential risks, especially when these global classes are provided by third-party libraries or frameworks. To avoid potential naming conflicts and compatibility issues in the future, it is recommended to extend these classes through inheritance.

Implementation with Inheritance

Extending the GameEntity Class

// GameEntity.d.ts
declare interface GameEntity extends GameEntity {
  // Custom property
  customProperty: string;

  // Custom method
  customMethod(): void;
}

Extending the GamePlayerEntity Class

// GamePlayerEntity.d.ts
declare interface GamePlayerEntity extends GamePlayerEntity {
  // Custom property
  customProperty: string;

  // Custom method
  customMethod(): void;
}

Usage Example

// Now you can safely access the custom properties and methods
entity.customProperty = "someValue";
entity.customMethod();

Important Notes

1. Ensure that custom properties and methods do not conflict with the parent class or other extensions.
2. It is recommended to define extensions in a separate module to avoid global pollution.
3. Please ensure that the relevant type declarations have been correctly loaded before use.
