 ## Packaging games
 
-The web is the first and the best choice for HTML games, but if you want to reach a broader audience and distribute your game in a closed ecosystem, you still can do that by packaging it. The good thing is that you don't need a few separate teams working on the same game for different platforms — you can build it once and use tools like [Phonegap](https://phonegap.com/) to package the game for native stores. The resulting packages are usually pretty reliable, but you should still test them and be on the lookout for small issues or bugs to fix.

 As well as being great for virtual interfaces, it can also be used for a casual 2D gaming experiences. It would be very difficult to do everything with only your hands, but it's totally doable for the simple Captain Roger's gameplay — steering the ship and shooting the bullets.
 
-There's a good [Hello World](https://developer-archive.leapmotion.com/documentation/javascript/devguide/Sample_Tutorial.html) tutorial available on the Leap Motion documentation pages, which will get you through the basics. You can also check out the tutorial about [using the Leap Motion plugin for Kiwi.js](https://webdesign.tutsplus.com/add-motion-control-to-a-kiwijs-game-with-the-leap-motion-controller--cms-20455t), or the case study of [building a web game with Leap Motion and Pixi.js](https://arstechnica.com/information-technology/2014/04/building-a-gesture-controlled-web-game-with-leap-motion/). Be sure to visit the [LeapJS repository on GitHub](https://github.com/leapmotion/leapjs) to learn about the JavaScript client for the Leap Motion controller and read the documentation there. If all else fails, there's also a [gallery of working examples](https://leap2.ultraleap.com/downloads/) you can look at.

 To get the Leap Motion working on your computer you have to first install it by following the steps at [docs.ultraleap.com](https://docs.ultraleap.com/hand-tracking/getting-started.html#installation-guides). When everything is installed and the controller is connected to your computer we can proceed with implementing support in our [little demo](https://github.com/end3r/JavaScript-Game-Controls/). First, we add a `<script>` tag with the `url` pointing at [this file](https://js.leapmotion.com/leap-0.6.4.min.js), and add `<div id="output"></div>` just before the closing `</body>` tag for outputting diagnostic information.
 
 We will need a few helper variables for our code to work — one for the purpose of calculating the degrees from radians, two for holding the horizontal and vertical amount of degrees our hand is leaning above the controller, one for the threshold of that lean, and one for the state of our hand's grab status. We next add these lines after all the event listeners for keyboard and mouse, but before the `draw` method:

 There are a whole host of other [roles](/en-US/docs/Web/Accessibility/ARIA/Roles) that can identify non-semantic element structures as common UI features that go beyond what's available in standard HTML, for example [`combobox`](/en-US/docs/Web/Accessibility/ARIA/Roles/combobox_role), [`slider`](/en-US/docs/Web/Accessibility/ARIA/Roles/slider_role), [`tabpanel`](/en-US/docs/Web/Accessibility/ARIA/Roles/tabpanel_role), [`tree`](/en-US/docs/Web/Accessibility/ARIA/Roles/tree_role).

 This example as-is works fine in terms of keyboard accessibility — you can happily tab between the different tabs and select them to show the tab contents. It is also fairly accessible too — you can scroll through the content and use the headings to navigate, even if you can't see what is happening on screen. It is however not that obvious what the content is — a screen reader currently reports the content as a list of links, and some content with three headings. It doesn't give you any idea of what the relationship is between the content. Giving the user more clues as to the structure of the content is always good.

 It is best not to invent new user interactions. For any interaction you do add, it is vital to spend time in the design stage; if you define a behavior poorly, or forget to define one, it will be very hard to redefine it once the users have gotten used to it. If you have doubts, ask for the opinions of others, and if you have the budget for it, do not hesitate to [perform user tests](https://en.wikipedia.org/wiki/Usability_testing).
