When comparing NeoAxis Engine vs jMonkey3, the Slant community recommends jMonkey3 for most people. In the question“What are the best 3D game engines?” jMonkey3 is ranked 11th while NeoAxis Engine is ranked 26th. The most important reason people chose jMonkey3 is:
Java is a well-optimized just-in-time compiled language. It's faster than languages without an effective native-code compiler such as Python or Ruby, similar in speed to other just-in-time compiled languages such as C#, while slightly slower than compiled languages such as C or C++ (with some low-level and numeric [benchmarks](http://benchmarksgame.alioth.debian.org/u64q/java.html) being similar to C++). Java also has a wide variety of high-class IDEs available.
Ranked in these QuestionsQuestion Ranking
Pro Royalty free
You can use the engine for any commercial products and keep all the profits since NeoAxis does not ask for any royalties.
Pro Completely free
Pro Simple interface
You can learn how to use Neoaxis in a few days.
Pro Excellent visual tools, map editor and resource editor
You can easily create maps/scenes and add custom objects with physics and animations in a few minutes.
Pro Lot of maps and game-modes already built-in
Has about 30 built-in maps with different game modes which can be opened by the map editor and their source code can be edited.
Pro Good IDE support
Supports Visual Studio, SharpDevelop or MonoDevelop.
Pro Java is a great development platform
Java is a well-optimized just-in-time compiled language. It's faster than languages without an effective native-code compiler such as Python or Ruby, similar in speed to other just-in-time compiled languages such as C#, while slightly slower than compiled languages such as C or C++ (with some low-level and numeric benchmarks being similar to C++).
Java also has a wide variety of high-class IDEs available.
Pro Multiplatform support
Code can be ported to mobile (iOS is in the works) and other Android supported devices with minor changes to the code (just change some implementations that vary on the platform such as inputs and user interface). It can even run on certain Raspberry Pi devices.
Pro Free and open-source
jMonkey is completely free, meaning it's possible to develop and release a game with no fees or royalties. Because it is open-source, jMonkey has plenty of people fixing bugs and, adding to the engine as well as creating a variety of plugins that can be used in the engine.
Pro Not limited to using its own IDE
Unlike some engines, jMonkey doesn't force its own IDE. You can use its Netbeans-based IDE, but you can also set up a project to work in another IDE such as Eclipse. You can still use the special tools from jMonkey's IDE in such projects.
Pro Engine modifications can be made using Java
Because jMonkey is implemented in Java, the same language its apps are typically developed in, developers will have an easier time modifying the engine to their needs.
Pro Has everything
jMonkey3 handles input from computers and mobile devices. It handles networking, physics, rendering, terrain, and cinematics.
Pro Ease of extensibility
Engine is modifiable.
Pro Freedom of choice for architecture
The user is not compelled to use any programming architecture nor standard in order to make a project working. JME allows the freedom to use what is best for a game.
Pro Offers both low-level and high-level ways of editing shaders
Modifying shaders can be done either via a visual tool called Shader Nodes or via GLSL that allow you to make your own shaders without the engine getting in the way or having to hack around to do so.
Con The developers do not actively communicate with the community
Not only have the developers driven the community away, they have actively closed the forum.
News articles have not had any changes since 2016, and the last news article still has links to the now removed forum.
NeoAxis Engine is Windows-only.
Con No community
As of 2016, the creator has completely destroyed his own community in order to silence any criticism from developers.
Con Lack of tutorials
Unfortunately, the wiki doesn't contain many programming tutorials, and the source code itself isn't very self-documented. Creating new gamemodes or AI will require lot of research for beginners.
Con Terrible API reference
The methods are not defined.
Con Not an engine for total beginners
While it's clear that you need to know Java first before using this engine, it is recommended that you have some programming experience as well. Most performance issues and memory leaks are more due to bad programming practices than the engine itself.
Con Slow release cycle
jMonkey3 lacks manpower to have a fast and decent release cycle.
Con Relies on archaic tool chain
jMonkey Engine uses Apache Ant for build automation, which is archaic and backwards, even by Java standards.
