Hello World Example

main.js

import { Game, Scene, Entity } from "kernelplay-js";
import { TransformComponent, BoxRenderComponent } from "kernelplay-js";

class MyScene extends Scene {
  init() {
    const box = new Entity();
    box.addComponent("transform", new TransformComponent({
      position: { x: 300, y: 200 }
    }));
    box.addComponent("renderer", new BoxRenderComponent({color:"red"}));
    
    this.addEntity(box);
  }
}

class MyGame extends Game {
  init() {
    const scene = new MyScene("Main");
    this.sceneManager.addScene(scene);
    this.sceneManager.startScene("Main");
  }
}

new MyGame({ width: 800, height: 600, fps: 60 }).start();
