Robot loading

The loading of a Javascript has some asynchronous behavior that is implemented via callbacks. It is important the the order or calls is done correctly to make sure the simulation behaves as expected. When fullyLoaded is completed the robot.enabled flag is set which e.g. is used in the onRender() method of Robot to make sure that rendering does not start prematurely.

rearrange example

  // rearrange
  rearrange() {
    console.log("rearranging ...");
    for (var partIndex in this.allParts) {
      var part = this.allParts[partIndex];
      // add pivots to the coxas
      if (part.name.match('(coxa|femur|tibia)[0-9]')) {
        console.log("rearranging " + part.name);
        part.pivot = new Pivot(part.name + "-pivot", part.x, part.y, part.z, part.rx, part.ry, part.rz);
      }
      // reparent tibias and femurs
      var limbMatches=part.name.match('(tibia|femur)([0-9])');
      if (limbMatches) {
        var limbName=limbMatches[1];
        var limbIndex=limbMatches[2];
        var newParent='femur';
        if (limbName==='femur')
          newParent='coxa';
        // make this limb a child of the newParent
        part.reparent(newParent+limbIndex);
      }
    }
    this.save();
  }
