Foreword This is a detailed example about how to encrypt and decrypt data with Go. The uses code is shorten, e.g. the error handling is not mentioned. The full working project with error handling and user interface could be found on Github here. Encryption Introduction and data This example de...

We can use the child-attached and child-detached events to listen for when the scene attaches or detaches an entity: entity.addEventListener('child-attached', function (evt) { if (evt.detail.el.tagName.toLowerCase() === 'a-box') { console.log('a box element has been attached'); }; }); ...

Updating Multi-Property Component Data To update component data for a multi-property component, we can pass the name of a registered component as the componentName, and pass an object of properties as the value. A string is also acceptable (e.g., type: spot; distance: 30), but objects will save A-F...

Systems can help separate logic and behavior from data if desired. We let systems handle the heavy lifting, and components only worry about managing its data through its lifecycle methods: AFRAME.registerSystem('my-component', { createComplexObject: function (data) { // Do calculations ...

The schema is an object that defines and describes the property or properties of the component. The schema’s keys are the names of the property, and the schema’s values define the types and values of the property (in case of a multi-property component): Defining schema in your component AFRAME.reg...

A component’s members and methods can be accessed through the entity from the .components object. Look up the component from the entity’s map of components, and we’ll have access to the component’s internals. Consider this example component: AFRAME.registerComponent('foo', { init: function () { ...

Audio and video assets will only block the scene if we set autoplay or if we set preload="auto": <a-scene> <a-assets> <!-- These will not block. --> <audio src="blockus.mp3"></audio> <video src="loadofblocks.mp4">&...

A-Frame's animation system can animate different types of properties. vec3 Properties A-Frame has standard vec3 components (i.e., position, rotation, and scale). These components consist of three factors: X, Y, and Z. We can pass three space-delimited numbers to the from and to attributes just a...

When an entity includes multiple mixins that define the same component properties, the right-most mixin takes precedence. In the example below, the entity includes both red and blue mixins, and since the blue mixin is included last, the final color of the cube will be blue. <a-scene> &l...

using System; using System.IO; using System.IO.Compression; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { string zipPath = @"c:\example\start.zip"; string extractPath = @"c:\example\extract...

We can load the model by pointing using the ID to an that specifies the src to a file: <a-scene> <a-assets> <!-- At first we load skeletal animation blending JSON as asset --> <a-asset-item id="hand" src="/path/to/hand.json"></a-asset-i...

If you want to use WebVR content mixed with HTML content, for example when you're making a extended showcase key content, you could use the embedded tag. When you're using this, it's possible to look around inside 360° content using the gyroscope of your smartphone or click and drag on computer. &l...

Directional lights are like a light source that is infinitely far away, but shining from a specific direction, like the sun. Thus, absolute position do not have an effect on the intensity of the light on an entity. We can specify the direction using the position component. The example below creates...

By default, A-Frame scenes inject default lighting, an ambient light and a directional light. These default lights are visible in the DOM with the data-aframe-default-light attribute. Whenever we add any lights, A-Frame removes the default lights from the scene. <!-- Default lighting injected by...

This example shows how to create a custom dragging behavior by Subclassing UIDynamicBehavior and subclassing UICollectionViewFlowLayout. In the example, we have UICollectionView that allows for the selection of multiple items. Then with a long press gesture those items can be dragged in an elastic, ...

If your application does not need any HTTP interface (for example for a console only app), you will want to disable at least Twig and SensioFrameworkExtra Just comment out those lines: app/AppKernel.php $bundles = [ //... // new Symfony\Bundle\TwigBundle\TwigBundle(), // new Sensio\Bundl...

Command git cherry shows the changes which haven't yet been cherry-picked. Example: git checkout master git cherry development ... and see output a bit like this: + 492508acab7b454eee8b805f8ba906056eede0ff - 5ceb5a9077ddb9e78b1e8f24bfc70e674c627949 + b4459544c000f4d51d1ec23f279d9cdb19c1d32b...
