Aspect ratio

For a seamless integration with the Phune Gaming platform we recommend all the games to be implemented using the aspect ratio of 1.775 (same as iPhone 5).

CSP restrictions

Phune Gaming fully supports Firefox OS. However, Phune Gaming is distributed as a Firefox OS privileged type of app which enforces the CSP (Content Security Policy) by default.

This may cause existing code to break. To guarantee your game is fully functional on Firefox OS, follow the best practices below during the development:

• Include all JavaScript and CSS files locally in your game instead of loading them remotely.
• Don't embed JavaScript in <script> tags in HTML files since the inline scripts are banned. You should place the code in an external JavaScript file and reference it via the src attribute.
• HTML event attributes like onclick and onload are also considered inline scripts, thus add them as event listeners in your JS files.
• Don't assign content to the innerHTML property of dimanically created <script> tags.
• Don't assign remote URLs to the src property of dinamically created <script> tags.
• Don't use the eval() function or the eval operator.
• Don't use the javascript: pseudo-protocol (e.g. <a href="javascript:alert('foo')">).
• Don't use the Function() constructor.
• Pass callable objects (i.e. functions) to setTimeout and setInterval. Strings and other data types are not callable objects.
• Don't use plugins (e.g. <object>, <embed>, etc.).
• Don't create Web Workers with remote URLs.

For additional information consult the applicable CSP restrictions for Firefox OS.
