LightComponent

core / LightComponent.js

LightComponent is used to wrap classes based on THREE.Light (it can be THREE.PointLight, THREE.DirectionalLight and other). LightComponent offers main functionality for working with lights and extends properties that you can define before executing light.

Usage with existing Three.js light.

That's how you can make a WHS.Element from a three.js light:

JavaScript

const ball = new WHS.Element(
  new THREE.PointLight(),
  [WHS.LightComponent]
);

Making a Light Component

JavaScript

import * as THREE from 'three';

// Basic component class.
import {Component} from 'whs/lib/core/Component';
// Decorator for THREE.Mesh for component class.
import LightComponent from 'whs/lib/core/LightComponent';
// Some utils that should help.
import {extend, loadMaterial} from 'whs/lib/utils/index';

@LightComponent
class BasicLight extends Component {
  constructor(params = {}) {
    super(params, BasicLight.defaults);

    // Defaults.
    extend(params, {
      color: 0xffffff
      intensity: 10
    });

    if (params.build) { // params.build is "true" by default. (@LightComponent)
      this.build(params);
      // Apply position & rotation, scale ...
      super.wrap();
    }
  }

  build(params = {}) {
    return new Promise((resolve) => {
      this.native = new THREE.PointLight(
        params.color
        params.intensity
      );

      resolve();
    });
  }

  clone() {
    return new BasicLight({build: false}).copy(this);
  }
}

export {
  BasicLight
};
