A camera situated at the average height of human eye level (1.6 meters or 1.75 yard or 5.25 feet). <a-entity camera="userHeight: 1.6" look-controls></a-entity>

When the active property gets toggled, the component will notify the camera system to change the current camera used by the renderer: var secondCameraEl = document.querySelector('#second-camera'); secondCameraEl.setAttribute('camera', 'active', true);

To fix entities onto the camera such that they stay within view no matter where the user looks, you can attach those entities as a child of the camera. Use cases might be a heads-up display (HUD). <a-entity camera look-controls> <a-entity geometry="primitive: plane; height: 0.2; wi...

The camera primitive determines what the user sees. We can change the viewport by modifying the camera entity’s position and rotation. Note that by default, the camera origin will be at 0 1.6 0 in desktop mode and 0 0 0 in VR mode. Read about the camera.userHeight property. <a-scene> <...

To position the camera, set the position on a wrapper . Don’t set the position directly on the camera primitive because controls will quickly override the set position: <a-entity position="0 0 5"> <a-camera></a-camera> </a-entity>

A convenient way to package your application is to write the scripts in your packages.json file and run them with the npm run command { "name": "AppName", "productName": "AppName", "version": "0.1.1", "main": ...

We can put assembly instructions inside a macro and use the macro like you would call a function. #define mov(x,y) \ { \ __asm__ ("l.cmov %0,%1,%2" : "=r" (x) : "r" (y), "r" (0x0000000F)); \ } /// some definition and assignment unsigned char sbox[...

_id is a 12 bytes hexadecimal number which assures the uniqueness of every document. You can provide _id while inserting the document. If you didn't provide then MongoDB provide a unique id for every document. These 12 bytes first 4 bytes for the current timestamp, next 3 bytes for machine id, next ...

On 32-bits systems, integers larger than PHP_INT_MAX are automatically converted to float. Outputting these as integer values (i.e. non-scientific notation) can be done with printf, using the float representation, as illustrated below: foreach ([1, 2, 3, 4, 5, 6, 9, 12] as $p) { $i = pow(1024,...

If you have: val r = Random(233) infix inline operator fun Int.rem(block: () -> Unit) { if (r.nextInt(100) < this) block() } You can write the following DSL-like code: 20 % { println("The possibility you see this message is 20%") }
