Touch Interaction test for Snapchat Lens Studio

VisibleToggle.js

// -----JS CODE-----
// Code runs runs during the `Initialized` event

// Properties set out of function scope are per-instance values
var isVisible = true;

var so = script.getSceneObject();
var mesh = so.getComponentByIndex("MeshVisual", 0);
var mat = mesh.getMaterial(0).clone();

// Setup instances of a material
mesh.clearMaterials();
mesh.addMaterial(mat);

// Main event logic in callback
function onTouchEnd(eventData) {
  isVisible = !isVisible;

  // Fire off a tween rather than setting material colors explicilty
  global.tweenManager.startTween(script.getSceneObject(), "box_alpha");

  // OLD: Set material colors explicitly
  // var color = mat.getPass(0).baseColor;
  // color.a = isVisible ? 1.0 : 0.0;
  // mat.getPass(0).baseColor = color;
}

// Register the events to listen to
var touchEvent = script.createEvent("TouchEndEvent");
touchEvent.bind(onTouchEnd);
