Superpowers Game THREE.js plugin

This plugin exposes THREE.js r73 to the Typescript API of the Game system for Superpowers, the extensible HTML5 2D+3D game engine.

Installation

This plugin depends on the DOM plugin, so you need to install it too.

Usage

Typically, runtime objects have an __inner property set to their conterpart instance on the engine side which will reference the THREE objects they works with (texture for a Sprite asset, threeMesh for a SpriteRenderer, ...).

The __inner property is likely not exposed, so you have to store the objects in a temp variable of type any to access it.

You also have direct access to the SupWebGLRenderer and SupThreeScene variables which are set to the instances of THREE.WebGLRenderer and THREE.Scene used by Superpowers.

Quick example

For instance, the following code creates the two cubes and the sphere you can see in the image below:

threejs-plugin-demo.png

class MyBehavior extends Sup.Behavior {
  awake() {

    // add a cube to an actor

    var geometry = new THREE.BoxGeometry( 1, 1, 1 );
    var material = new THREE.MeshBasicMaterial( {color: 0xFF4784, wireframe: true} );
    var cube = new THREE.Mesh( geometry, material );

    var tmpActor: any = this.actor; // necessary to access __inner which isn't in the definitions
    tmpActor.__inner.threeObject.add( cube );

    this.actor.setEulerAngles( new Sup.Math.Vector3(0,20,0) );


    // create another cube and set the same texture as Sup's logo

    var tmpSprite: any = Sup.get("Sup Logo", Sup.Sprite);

    var material = new THREE.MeshBasicMaterial( {
      map: tmpSprite.__inner.textures.map,
      //transparent: true,
      color: 0x96FF96, // 150,255,150
      //wireframe: true
    } );
    var cube = new THREE.Mesh( geometry, material );
    cube.rotation.fromArray( [0,-20,0] );

    var tmpActor: any = Sup.getActor("Textured Cube");
    tmpActor.__inner.threeObject.add( cube );
    tmpActor.__inner.threeObject.updateMatrixWorld();


    // create a sphere and add it directly to Sup's scene.

    var sphereGeometry = new THREE.SphereGeometry( 1 );
    var material = new THREE.MeshBasicMaterial( {color: 0x479684, wireframe: true} );
    var sphere = new THREE.Mesh( sphereGeometry, material );
    sphere.position.set(0, 3, 0);

    SupThreeScene.add( sphere );
    SupThreeScene.updateMatrixWorld(true);
  }
}
