jMonkeyEngine (original) (raw)
jMonkeyEngine is a modern developer friendly game engine written primarily in Java.
Its minimalistic and code first approach makes it perfect for developers who want the support of a game engine while retaining full control over their code with the ability to extend and adapt the engine to their workflow.

MacOS renting and development in the cloud
MacOS cloud renting has started to proliferate with the new Apple Silicon M1 chip and it turned out to be a pretty decent way to test graphical applications on MacOS without buying apple’s pricey hardware or resorting to hackish ports and vms of questionable legality. I am reporting here the procedure to quickly get a MacOS M1 cloud service up and running for testing jmonkey applications without too much hassle. …Read More...

Powerful Graphics
jMonkeyEngine is only one level of abstraction away from OpenGL.
The engine exposes modern opengl capabilities and benefits from high performances due to its low level of abstraction.
Notable features include:
- Physically Based Rendering
- Singlepass Lighting
- Instanced Rendering
- Multitarget Rendering
- Tessellation
- Geometry Shaders
- Offscreen Rendering
- sRGB support with linearization
- Floating point textures
- Tone Mapping (HDR)
- Steep Parallax
- Shadows And more...
Physics
jMonkeyEngine supports multiple physics solutions
- jBullet: java porting of Bullet Engine
- Minie : A binding to Bullet Engine, with support for rigidbody and softbody physics
Networking
There are multiple options to write netcode in jMonkeyEngine:
- Spidermonkey: A feature rich java client-server networking API that uses TCP and UDP packets. With support for RMI and Object Serialization.
- SimEthereal : A high performance library for real-time networked object synching
- Monkey Netty : A implementation of a server-client system using Netty.IO that utilizes both TCP and UDP.
GUI
In jMonkeyEngine there are several established choices for GUIs:
- Lemur : a modular library for 2D and 3D interactive guis, with a groovy-based styling language
- Nifty GUI: a library to build interactive user interfaces with support for xml layouts.
- IGUI : a minimalistic immediate GUI with minimal input handling
Postprocessing
jMonkeyEngine supports postprocessing out of the box and comes with several filters ready to use.
Such as:
- Bloom
- FXAA
- Cartoon Edges
- Light Scattering (GOD rays)
- SSAO
- Tone Mapping
- Volumetric Light And more...
3D Audio
jMonkeyEngine supports 3D audio with
- OpenAL: Cross platform 3D audio. With basic support for positional sound and precomputed reverb.
- jmePhonon : Binding to SteamAudio for immersive sounds. With support for HRTF, occlusion, realtime reverberance and more... (pc only)
Terrain
There are several libraries and frameworks that aid in the creation of terrains in jMonkeyEngine.
Notable choices are:
- TerraMonkey: An high performance editable heightmap based terrain with autogenerated LOD and triplanar mapping.
- Blocks : A voxel engine with support for custom shapes, physics and endless terrain.
- IsoSurface : An isosurface terrain
- SimArboreal : A library to generate procedural trees
- SeaMonkey: Postprocessing filter that simulates water and underwater effects
Particles
jMonkeyEngine comes with particles capabilities in the core and multiple advanced thirdparty alternatives:
- jMonkey Particles: Simple and fast particles with support for point sprites and basic emitter logic
- Particle Monkey : A modern particle system with better artistic controls
- jme-EffekseerNative : Binding to the Effekseer particles runtime.
Multy Paradigm
Thanks to its flexibility, jMonkeyEngine can be used with different paradigms:
- Spatial-Control model: An intuitive model where Spatials are game entities and Controls determine their logic
- Zay-ES : High-performance entity-component-system model (ECS)
By The Community
During the years jMonkeyEngine has received many contributions in form of addons, assets and libraries.
Recently we launched the Software Store to collect all of them in a single place.
For The Developers
Simple, easy to setup, modular and minimalistic in its approach, jMonkeyEngine is made for the developers.
Its flexibility allows it to be adapted to different workflows and easily extended to support new features.
Free for everyone
jMonkeyEngine is free and opensource. Released under the permissive BSD 3-Clause license.
No splash screens, no fees and no requirement to mention jMonkeyEngine in your game at all.
