@yagejs/core

ECS, math, events, and scheduling - the foundation of the YAGE 2D game engine.

Install

npm install @yagejs/core

What's in the box

• Engine - the game loop and plugin host
• Scene / SceneManager - scene stack with push/pop, pause, and time scaling
• Entity / Component - ECS primitives with typed queries
• Transform / Vec2 - 2D math and spatial positioning
• EventBus - typed, decoupled events with defineEvent
• Blueprint / Trait - composition helpers
• Process / Tween / Sequence - timers, easing, and keyframe animation
• AssetManager - async resource loading
• Inspector - snapshot introspection for tests and debug tools

Usage

import { Engine, Scene, Entity, Component, Transform, Vec2 } from "@yagejs/core";

class Player extends Entity {
  setup() {
    this.add(new Transform({ position: new Vec2(100, 100) }));
  }
}

class GameScene extends Scene {
  readonly name = "game";

  onEnter() {
    this.spawn(Player);
  }
}

const engine = new Engine();
await engine.start();
engine.scenes.push(new GameScene());

@yagejs/core has zero runtime dependencies. On its own it's a pure ECS - add @yagejs/renderer to draw things, @yagejs/physics for collisions, @yagejs/input for controls, etc.
