Orx vs Starling

Powerful config system that makes orx data-driven and provides an easy to use load/save system.

Good friendly development community ready to help each other with tips and advice for setting up and best practices.

Automatic hot-loading of resources upon modification on disk, shortens drastically iteration times.

Written in C with high emphasis on memory and CPU efficiency.

Supports Windows, Linux, Mac OS X, iOS and Android.

Orx is a Data Driven engine that greatly reduces required code. You can configure object definitions, bodies, cameras, sound, animation, event tracks, etc.

GLSL code can be added straight into data configuration files and can be applied to any texture: background or objects whivh allows for some amazing effects. All GLSL versions are supported, again by providing the shader language version in your configuration file.
Parameters are supported and values over time for shader animation.

Clock system that provides time consistency and allows time stretching + high precision timers

Color and translation FX are simple to configure and apply to objects.

Includes a chaining graph & custom animation events for synchronization.

Uses the zlib license. Lets you use Orx for free for any kind of projects, even for commercial ones.

All input devices are fully supported: Joysticks, Mouse, Gamepad, Keyboard and Touchscreen. Multiple physical devices and be mapped the same binding.

Rated the fastest engine in the OpenFL’s BunnyMark since October 2015.

Samples for sound effects, or streams for music. All sounds can be groups via audio buses just like in a typical DAW (Digital Audio Workstation).
All sounds can be spatial relative to the camera.

Camera/viewport scheme allowing multiple views displayed with camera translation, zoom and rotation.

Fragment (pixel) shader support, render to texture, MRT, easy composition and custom rendering support.

Integrated runtime profiler (with graphical display) to easily spot which parts of your game need to be optimized.

Supports .bmp, .png, .jpg, .tga and .dds

Out of the box Windows support for:

• Visual Studio
• Codelite
• CodeBlocks
• gmake

Out of the box Mac support for:

• XCode
• Codelite
• gmake

Out of the box Linux support for:

• Codelite
• CodeBlocks
• gmake

Orx provides a excellent c++ wrapper for object oriented design, called: orx/Scroll. You can, of course, roll your own.

Starling is just 12k lines of code and doesn't try to do everything — but what it does, as efficient as possible.

With Feathers, you can easily add great user interfaces to your games — or even create business apps with Starling.

Starling is available for free with code available on GitHub.

Forum is always active with knowledgeable developers and with lot of inside info, and post mortems.

With UI, you can design it in Flash Professional (powerful 2D editor), export to swf file, use GAF convert swf file to gaf file, finnally, load gaf file to Starling. GAF can convert a lot of file swf to one atlas. Alway use same resource in design files (fla) to optimize atlas size, avoid duplicate asset in atlas.

You can use flash to create animation for starling.

Let the GPU do the rendering, the CPU has more important tasks to do.

It can be exported to web flash player, iOS, Android, Windows, and OS X

Using AIR's native extensions any native code that can be written can be run and used by the game engine.

New features are added regularly.

Starling can run more animated display objects than Unity2D and many others frameworks at 60 fps.
