When comparing libGDX vs Felgo (formerly V-Play), the Slant community recommends libGDX for most people. In the question“What are the best 2D game engines?” libGDX is ranked 17th while Felgo (formerly V-Play) is ranked 41st. The most important reason people chose libGDX is:
Lots of references, tutorials and open source code to learn from.
Ranked in these QuestionsQuestion Ranking
Pro Lots of resources to learn from
Lots of references, tutorials and open source code to learn from.
Pro Great performance across devices
While it may not always have the best performance for a particular device or system, it's one of the few engines which consistently performs very well across different platforms.
Pro Allows you to migrate from 2D to 3D within same framework
LibGDX supports both 2D and 3D game development. Allowing developers to migrate from 2D to 3D with ease without having to switch the engine they are using or having to learn a new API.
Pro Doesn't force a specific design
Unlike some engines, which only allow you to make your game in a few specific ways, libGDX allows you to design any type of game you wish as it is extremely customisable.
Pro Active and helpful community
The libGDX community, in the official libGDX forum is extremely helpful and approachable for any kind of question regardless of the its quality or difficulty.
The forums themselves are a very helpful resource for any issue or guide simply by searching past posts in there.
In addition to the forums, there's also the official #libgdx IRC channel on Freenode.
Pro Uses Box2D
A Java port of the Box2D physics engine is included in libGDX.
Pro Interfacing with platform specific code
Sometimes it is necessary to access platform specific APIs, e.g., adding advertisement services or leaderboard functionality provided by frameworks.
Pro Can use any JVM language
Since it's built with Java and runs on the JVM, any language that compiles to Java bytecode can be used to develop games with libGDX.
Pro Free, open source & permissive license
libGDX uses the Apache License 2.0.
Not only is libGDX free and open source but also it's license gives you a lot of power over the engine. As long as you provide a copy of the license, give credit, do not hold devs liable and do not use libGDX logo in any engine forks you can do pretty much anything you want.
Pro Kotlin support
It is written in Java so you can easily make games using Kotlin and Ktx project will help you get all advantages of this language.
Pro Very easy to customize
Pro Constantly improved
LibGDX itself is pretty mature, and get updates not quite frequently, but various libraries for it are actively updated.
Pro Across platform support
You can write once and run anywhere (Android, IOS, Desktop, Browser) also lately came with lib to deal with VR.
Pro Support for 3rd party tools
libGDX has built in support for many 3rd party tools, including (but not limited to) Bullet Physics, Box2DLights and the well-praised Tiled Map Editor.
Pro Lots of tutorials to get you going
Even though the official documentation might be lacking, there are many tutorials on YouTube for libGDX.
Pro Excellent font rendering support
Very good tools for rendering fonts.
Pro Similar to the Microsoft XNA framework
Old XNA users may like libGDX since it's API is actually very similar to XNA's.
Pro Focusing on object pool patterns, to control memory without pointers
Unlike Unity or other engine, it allows to optimize a language that uses garbage collector when using patterns of objects you can control the use of memory without needing a language like C / C ++, getting the same speed in a more productive language.
Pro Mature cross platform IDE
Qt-Creator IDE with Code Completion, Debugging and Profiling, integrated Quick Help, Version Control and more.
Pro Easy to learn
Felgo is among the easiest cross-platform tools to use according to a survey done by research2guidance.
Pro In-game level editor
With the Level Editor components, you can let your players share their levels with the whole game community which is cool because you don't need to create new levels on your own, but the community helps you with it. There are other community features like rewards for good level creators that helps getting more downloads.
Pro Felgo game network
Leaderboards, Achievements, Challenges are available across platform, even on Desktop. You can also use Cloud Syncinc of your game data that makes it easy to start a game for example on iPhone and then continue on a Nexus Tablet or the other way around.
It is also convenient because sharing to all kind of game services & networks like Facebook & Game Center is possible with a single API call. Custom hosting of Game Network servers is also possible if you want to keep the player data.
Pro Native performance
Pro Advanced gaming components
Advanced Gaming Components for handling multiple display resolutions & aspect ratios, animations, particles, physics, multi-touch, gestures, path finding and more.
Pro Felgo build server
No need for native SDKs, Build in and Install from Cloud with the Felgo Build Server.
Pro Rapid development
Cut your development time in half. Using the QML language allows for some powerful features that cut code lines and time. Another helpful feature that can help in this area is that there are more than 50 game demos of all genres that come with full source code, meaning one can easily check to see how something was done.
Pro Support can be found in forums and via e-mail
Felgo has friendly forums where core developers participate as well as fast & helpful email support.
Pro Based on Qt framework
The Qt framework is a great and mature framework on its own. Using Qt as a game engine base is a smart idea.
You can use ready-made components to balance any of your game properties at runtime, so also on mobile devices which is great for adjusting forces or input parameters.
Pro Lots of learning resources
Helps get started and improve with lots of tutorials, demo games, examples.
Pro Social services and monetization
In-app purchases, game and social network integration (such as Game Center and Facebook), ads (with Chartboost and AdMob) and analytics (such as Flurry) are all available across platforms.
Pro Frequent updates
Every 2-4 weeks new updates provide additional features and fixes based on what users wanted the most.
Pro Level store
You can even monetize these user-generated levels with in-app purchases with the Felgo Level Store component if you like.
Con Not starter friendly
Even default applications fail to load in Android. It doesn't have any documentation on errors either.
Con The project slowed down in development
The number of active developers has decreased, many open issues and pull requests.
Con Build system is clunky
LibGDX uses Gradle, which is very demanding of memory and makes IDEs freeze on anything if your computer is not powerful enough.
Con Does not create compiled code
LibGDX runs entirely on Java and does not create executable binaries.
Con A bit difficult to use
This engine is not well put together. Is made from various free modules each with their own peculiarities. At times it feels you need to learn a couple of libraries rather than just one. Is not an engine for beginners as it requires coding. Lots of coding. You need to be intermediate to advanced in Java to develop in LibGDX.
Con No 3rd party tutorials
There are little to none amount of tutorials for Felgo other than what was made by the engine developers themselves.
