When comparing Cocos2d-x and Cocos2d Family vs Starling, the Slant community recommends Cocos2d-x and Cocos2d Family for most people. In the question“What are the best 2D game engines?” Cocos2d-x and Cocos2d Family is ranked 7th while Starling is ranked 70th. The most important reason people chose Cocos2d-x and Cocos2d Family is:
Ranked in these QuestionsQuestion Ranking
Pro Great script language support
Especially with Cocos2d-JS you can develop games cross web and native, and the native solution have great performance with JS Bindings, much better than hybrid solution.
Pro A proven engine for mobile development
25% of iPhone games are made using Cocos2d-x (A Cocos2d mobile variant.)
This means you will not be alone in development, and will have access to a large community. You'll know you are developing for an engine that works.
Pro Highly active community for questions and support
Cocos2d-x forums are active.
Pro Supports 3D models with skeleton animation
A new feature since Cocos2d-x v3.1 is support for 3D models (in your 2D game), not only this but support for skeleton animations is included too! This awesome feature allows for impressive characters in your game along with easier, more fluid and realistic animations.
Cocos2d-x is not only open source but also supported by Chukong Technologies of China and USA.
Regularly updated and adding support for the latest technologies. 2014 has already seen the release of Version 3, a new Cocos Studio development toolkit (optional) and support for new technologies like skeleton animation systems Spine and Adobe DragonBone.
Pro Greater performance than high level APIs
Cocos2d-x is C++ based engine and it has CPU advantages for most platforms because of that. It uses polygonal mesh methods for sprite rendering for using GPU advantages. (You also use quad methods for benefit CPU).
Pro Allows for easy debugging
It has a built-in Python interpreter that allows for easy debugging.
Pro Great video tutorials
Hundreds of video tutorials available.
Pro OpenGL hardware acceleration
Pro Easy integration of 3rd party plugins
For example, if you want to add a rating plugin, you use
sdkbox::PluginReview::init(); and if you want to add the Vundle Ad Network SDK, you use the one packaged in SDKBox
Pro No external dependencies
Because it is based on Pyglet.
Starling is just 12k lines of code and doesn't try to do everything — but what it does, as efficient as possible.
Pro Feathers User Interface Components
With Feathers, you can easily add great user interfaces to your games — or even create business apps with Starling.
Pro Free and open source
Starling is available for free with code available on GitHub.
Pro Strong community support
Forum is always active with knowledgeable developers and with lot of inside info, and post mortems.
Pro Works with Flash
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.
Pro Hardware accelerated rendering
Let the GPU do the rendering, the CPU has more important tasks to do.
Pro Cross Platform
It can be exported to web flash player, iOS, Android, Windows, and OS X
Pro Works with AIR's native extensions
Using AIR's native extensions any native code that can be written can be run and used by the game engine.
Pro Constantly updated
New features are added regularly.
Pro Better performance than most alternatives
Starling can run more animated display objects than Unity2D and many others frameworks at 60 fps.
Con Poor documentation
Most existing documentation is out of date. API documentation sometimes exists, though is usually just a one-liner and more often than not is completely absent. New features and significant system rewrites often make it to a major release without a single line of documentation accompanying them. Cocos2d-x family is developed by Chinese mostly, so market outside of China is not their main priority. Some tools (like Cocos Studio) have China-specific services and markets.
Con Poor support and non-existent community
Up until 2013, this was one of the best engines around. However, since then it was bought by a Chinese company and began stagnating - it's virtually in a slow death. Most developers abandoned Cocos in favor of more modern solutions leaving the community weak and the forums with little or no traffic. Although the Cocos2d-x Forum seems to have a decent community going.
Con Cocos2d-html5 is way behind Cocos2d-x
While Cocos2d-html5 tries to mimic it's Cocos2d-x sister and has the same people working on it, it has lots of restrictions compared to Cocos2d-x: no Spine mesh support, no 3D models, bad text label quality, etc.
Con Inefficiency in making 3D games
Con Fragmentation; hard to find useful tutorials
Cocos2d family includes different projects: cocos2d-x, cocos2d-html5, cocos2d-objc, cocos2d-XNA. Most tutorials describe techniques specific to single project of the family, and cannot be applied to other projects.
Con Can seem very complex for a novice developer
There isn't much documentation or tutorials.
Con Modest functionality
Almost all free alternatives are more convenient, faster, and more functional.
Con Poor text/font support
It supports only 4 features for text rendering:
- bitmap font with batching.
1.1. basic distance fields with support for outline and filters via MeshStyle.
1.2 the new multichannel distance field, the ultimate solution for bitmap font rendering.
- Draw and upload texture in runtime
So every new text field required texture uploads or vertex/idnex buffer uploads.
skipUnchanchagedFrames keep the backbuffer static for scenes without changes between frames, leveraging a good rendering optimization.
Con Engine supported mainly by one man
Its open source but in most cases community features or pull request are canceled.
