'''jMonkeyEngine''' (abbreviated '''JME''' or '''jME''') is an open-source and cross-platform [[game engine]] for developing [[3D computer graphics|3D]] games written in [[Java (programming language)|Java]].<ref>{{Cite web |title=JMONKEYENGINE |url=https://jmonkeyengine.org/ |website=jMonkeyEngine}}</ref> It can be used to write games for [[Microsoft Windows|Windows]], [[Linux]], [[macOS]], [[Raspberry Pi]], [[Android (operating system)|Android]], and [[iOS]] (currently in alpha testing). It uses [[Lightweight Java Game Library]] as its default renderer, and also supports another renderer based on [[Java OpenGL]].

jMonkeyEngine is community-centric and [[open-source software|open-source]]. It is released under the [[New BSD License|New BSD license]]. It is used by several commercial game studios<ref>{{Cite web

==jMonkeyEngine 3 SDK==
By itself, jMonkeyEngine is a collection of [[Library (computing)|computing libraries]], making it a [[High and low level|low-level]] [[game development tool]]. Coupled with an [[integrated development environment]] like the official jMonkeyEngine 3 SDK, it becomes a higher-level game development environment with multiple graphical components. 

The SDK is based on the [[NetBeans Platform]], enabling graphical editors and [[Plug-in (computing)|plugin]] capabilities. Alongside the default NetBeans update centers, the SDK has its own plugin repository and a selection between stable [[point release]]s or nightly updates. 

Since March 5th, 2016, the SDK is no longer officially supported by the core team. It is still being actively maintained by the community. The term "jMonkeyPlatform" is also used interchangeably with "jMonkeyEngine 3 SDK."

==History==
jMonkeyEngine helps to improve the lack of full featured graphics engines written in Java. The project has evolved over time.

===jMonkeyEngine 0.1 – 2.0===
Version 0.1 to 2.0 of jMonkeyEngine marks the time from when the project was first established in 2003, until the last 2.0 version was released in 2008. When the original core developers gradually discontinued work on the project throughout the end of 2007 and the beginning of 2008, Version 2.0 had not yet been made officially stable. The code-base became adopted for commercial use and was most popular with the engine's community at the time.

{{timeline-start}}

{{timeline-item|{{Start date|2003}}|Initial work on jMonkeyEngine was begun by Mark Powell (aka MojoMonkey) as a side project to see if a fully featured graphics API could be written in Java.  Much of the early work on the API was inspired by David Eberly's C++ book ''3D Game Engine Design''.}}

{{timeline-item|{{Start date|2004|01}}|Mark was joined by Joshua Slack (aka Renanse) and together over the following two years, with the help of other community contributors, a commercially viable API was developed.}}

{{timeline-item|{{Start date|2008|08|15}}|Joshua Slack announces to step back from active development of the jMonkeyEngine.<ref>{{Cite web

===jMonkeyEngine 3.0===
Since the departure of jME's core developers in late 2008, the codebase remained practically stagnant for several months. The community continued to commit patches, but the project was not moving in any clear direction. Development on Version 3.0 started as an experiment. 

The first preview release of jME3 in early 2009 drew positive attention<ref>{{Cite web

}}</ref> from many members in the community, and the majority agreed that this new branch would be the official successor to jME 2.0. From there on, all the formalities were sorted out between the previous core developers and the new.
