Common Lisp has 12 type specific operators to compare two characters, 6 of them case sensitives and the others case insensitives. Their names have a simple pattern to make easy to remember their meaning: Case SensitiveCase InsensitiveCHAR=CHAR-EQUALCHAR/=CHAR-NOT-EQUALCHAR<CHAR-LESSPCHAR<=CHA...

The core idea is to use GameObjects to represent singletons, which has multiple advantages: Keeps complexity to a minimum but supports concepts like dependency injection Singletons have a normal Unity lifecycle as part of the Entity-Component system Singletons can be lazy loaded and cached loca...

We can use the componentchanged event to listen for changes to the entity: entity.addEventListener('componentchanged', function (evt) { if (evt.detail.name === 'position') { console.log('Entity has moved from', evt.detail.oldData, 'to', evt.detail.newData, '!'); } });

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...

For example, if we wanted to grab an entity’s three.js camera object or material object, we could reach into its components var camera = document.querySelector('a-entity[camera]').components.camera.camera; var material = document.querySelector('a-entity[material]').components.material.material; ...

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...

A component holds a bucket of data in the form of one or more component properties. Components use this data to modify entities. Consider an engine component, we might define properties such as horsepower or cylinders. HTML attributes represent component names and the value of those attributes repr...

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...

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 () { ...

Components can be attached to the scene as well as entities. A-Frame ships with a few components to configure the scene: ComponentDetailsembeddedRemove fullscreen styles from the canvas.fogAdd fog.keyboard-shortcutsToggle keyboard shortcuts.inspectorInject the A-Frame Inspector.statsToggle performa...

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...

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...

There are various types of inheritance and code reuse in Twig: Include The main goal is code reuse. Consider using header.html.twig & footer.html.twig inside base.html.twig as an example. header.html.twig <nav> <div>Homepage</div> <div>About</div> </...

When generating new Angular 2 components in a .NET Core project, you may run into the following errors (as of version 0.8.3): Error locating module for declaration SilentError: No module files found OR No app module found. Please add your new Class to your component. Identica...

This is a small example of an autocomplete input. CSS .autocomplete { position: relative; } .autocomplete-list { position: absolute; z-index: 2; top: 25px; min-width: 150px; margin: 0; padding: 0; list-style: none; border: 1px solid #eee; border-radius: 4px; ...

Kernels can be compiled at runtime on the target device. To do so, you need the kernel source code the target device on which to compile a context built with the target device A quick terminology update: A program contains a collection of kernels. You can think of a program as a complete C/C...
