ArchitectureEdit

Felgo is based on the Qt (software) cross-platform development framework that provides abstraction layers for timers, threads, storage, networking and UI rendering on different platforms. Applications built with Qt include VLC Media Player, Skype and Autodesk Maya – all of them make use of the GUI module which allows the creation of native-looking applications with a single source code base.[6]

Felgo uses Qt as its core and offers components and plugins on top of it, which further simplify the development of apps and games.[7]

Engine FeaturesEdit

Qt Creator IDEEdit

The Qt Creator IDE supports editing QML and JavaScript code with context-sensitive help, code completion of Felgo components, navigation between components and more.

It includes a QML debugger and profiler for debugging custom components and JavaScript functions. It can inspect and change property values and QML code at runtime and is able to measure the time of element creation and binding evaluations.[8]

Declarative Language FeaturesEdit

Felgo apps and games are written in JavaScript and QML, a declarative language that features property bindings, state machines or fluid animations of any property.[9]

Resolution & Aspect Ratio IndependenceEdit

Felgo is built to handle all possible aspect ratios and resolutions of modern mobile devices. Developers create their game for a logical scene using a content scaling approach.[10]

Native Dialogs and FunctionalityEdit

Felgo apps and games provide a native look and feel on all platforms. Felgo has abstracted components for displaying native input dialogs and alert boxes without the need of a single native code line.[11]

Felgo Game NetworkEdit

The Felgo Game Network is a mobile-backend-as-a-service or MBaas. It allows players to compare high scores and achievements, as well as syncing their data across devices. This is a free service for players and doesn't require registration of any kind. The Felgo Game Network can be implemented in less than 50 lines of code.[12]

Third Party PluginsEdit

Felgo apps and games support a number of 3rd party plugins.[13] These plugins can be used by developers to monetize their applications, to gather analytics on user behavior or to engage users. The following plugins are currently supported by Felgo:

Supported platformsEdit

Felgo supports the following platforms.[14][15][16]
