entityx-ts

entityx-ts is an Entity Component System (ECS) library for TypeScript, designed for high performance and flexibility.
It is used in projects like safex-pixi for game and interactive application development.

Installation

npm install entityx-ts

Basic Usage

1. Create an Entity

import { World } from 'entityx-ts';

const world = new World();
const entity = world.entities.create();

2. Define Components

class Position {
    constructor(public x: number, public y: number) {}
}

class Velocity {
    constructor(public dx: number, public dy: number) {}
}

3. Add Components to Entities

entity.assign(new Position(0, 0));
entity.assign(new Velocity(1, 1));

4. Create Systems

class MovementSystem {
    update(world: World) {
        for (const entity of entities.entities_with_components(Position, Velocity)) {
            const pos = entity.getComponent(Position);
            const vel = entity.getComponent(Velocity);
            pos.x += vel.dx;
            pos.y += vel.dy;
        }
    }
}

5. Run the World

function gameLoop() {
    const movementSystem = world.systems.get(MovementSystem);
    movementSystem.update(dt);
    requestAnimationFrame(gameLoop);
}

gameLoop();

Integration with safex-pixi

safex-pixi uses entityx-ts to manage game entities and components, enabling scalable and maintainable game logic.
Refer to safex-pixi for advanced usage and integration examples.
