Mobile touch controls - Game development
input events instead of using the pointers directly it is also possible to listen for this.game.input events, like ondown, onup, ontap and onhold: this.game.input.ondown.add(item
touched, this); function item
touched(pointer) { // do something } the item
touched() function will be executed when the ondown event is dispatched by touching the screen.
... this approach uses the generally available this.game.input object, but you can also detect the actions on any game objects like sprites or buttons by using oninputover, oninputout, oninputdown, oninputup, ondragstart, or ondragstop: this.button.events.oninputover.add(item
touched, this); function item
touched(button, pointer) { // do something } that way you'll be able to attach an event to any object in the game, like the player's ship, and react to the actions performed by the user.
... implementation the easiest way to add an interactive object that will listen for user input is to create a button: var buttonenclave = this.add.button(10, 10, 'logo-enclave', this.clickenclave, this); this one is formed in the mainmenu state — it will be placed ten pixels from the top left corner of the screen, use the logo-enclave image, and execute the clickenclave() function when it is
touched.
Pointer events - Web APIs
for touch input, a pointer is considered primary if the user
touched the screen when there were no other active touches.
... button#tiny { touch-action: none; } in the following example, when the target element is
touched, it will only pan in the horizontal direction.
Scaling - Game development
show_all — scales the canvas, but keeps the aspect ratio un
touched, so images won't be skewed like in the previous mode.

Implementing feature detection - Learn web development
let's recap and look at the example we
touched on in our handling common javascript problems — the geolocation api (which exposes available location data for the device the web browser is running on) has the main entry point for its use, a geolocation property available on the global navigator object.

SpiderMonkey compartments

touched by a website are tightly packed next to each other in memory, with no cross-origin objects in between.
nsIContentViewManager
this lets you, for example, take the coordinates at which the user clicked (or
touched) the screen, and expand outward to create a rectangle from that point.
nsIPluginHost
if "content-length" string and end of headers is found it substitutes single lf with crlf in the headers, so the end of headers always will be crlfcrlf (single cr in headers, if any, remain un
touched) else it puts "content-length: "+size_of_data+crlfcrlf at the beginning of the output buffer and memcpy data to the output buffer.
ElementCSSInlineStyle.style - Web APIs
examples // set multiple styles in a single statement elt.style.csstext = "color: blue; border: 1px solid black"; // or elt.setattribute("style", "color:red; border: 1px solid blue;"); // set specific style while leaving other inline style values un
touched elt.style.color = "blue"; getting style information the style property is not useful for completely learning about the styles applied on the element, since it represents only the css declarations set in the element's inline style attribute, not those that come from style rules elsewhere, such as style rules in the <head> section, or external style sheets.
Index - Web APIs
if there is any risk of an element being removed while it is being
