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...

A system is registered similarly to a A-Frame component. If the system name matches a component name, then the component will have a reference to the system as this.system: AFRAME.registerSystem('my-component', { schema: {}, // System schema. Parses into `this.data`. init: function () { ...

There is no strict API for defining how systems manage components. A common pattern is to have components subscribe themselves to the system. The system then has references to all of its components: AFRAME.registerSystem('my-component', { init: function () { this.entities = []; }, ...

AFRAME.registerComponent (name, definition) Register an A-Frame component. We must register components before we use them anywhere in . Meaning from an HTML file, components should come in order before . {string} name - Component name. The component’s public API as represented through an HTML at...

Property types primarily define how the schema parses incoming data from the DOM for each property. The parsed data will then be available via the data property on the component's prototype. Below are A-Frame's built-in property types: Property TypeDescriptionDefault ValuearrayParses comma-separ...

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 () { ...

Every element in A-Frame inherits from <a-node>, the AFRAME.ANode prototype. ANode controls load and initialization order. For an element to initialize (whether it be <a-assets>, <a-asset-item>, <a-scene>, or <a-entity>), its children must have already initialized. N...

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...

Properties of a multi-property component will merge if defined by multiple mixins and/or the entity. For example: <a-scene> <a-assets> <a-mixin id="box" geometry="primitive: box"></a-mixin> <a-mixin id="tall" geometry="heigh...

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...

One common use of variable-length argument lists is to implement functions that are a thin wrapper around the printf() family of functions. One such example is a set of error reporting functions. errmsg.h #ifndef ERRMSG_H_INCLUDED #define ERRMSG_H_INCLUDED #include <stdarg.h> #include...

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 register our own primitives (i.e., register an element) using AFRAME.registerPrimitive(name, definition). definition is a JavaScript object defining these properties: PropertyDescriptiondefaultComponentsObject specifying default components of the primitive. The keys are the components' nam...

You must use a ScriptManager control on a page to enable the following features of ASP.NET AJAX: 1. Client-script functionality of the Microsoft AJAX Library, and any custom script that you want to send to the browser. protected void Button1_Click(object sender, EventArgs e) { Page.ClientScr...

Hemisphere lights are like an ambient light, but with two different colors, one from above (color) and one from below (groundColor). This can be useful for scenes with two distinct lighting colors (e.g., a grassy field under a gray sky). <a-entity light="type: hemisphere; color: #33C; groun...

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...

If for some reason using the Symfony Installer is not an option, you can also create a new project using Composer. First of all, make sure you have installed Composer. Next, you can use the create-project command to create a new project: composer create-project symfony/framework-standard-edition m...

After creating a new Symfony application, you can use the server:run command to start a simple PHP web server, so you can access your new application from your web browser: cd my_project_name/ php bin/console server:run You can now visit http://localhost:8000/ to see the Symfony welcome page. ...
