Implemented support for cpu-based pixel shading for a single pass on …

…texture load-time. Essentially, this allows render effects to be applied to assets as they are loaded. It isn't your traditional shader (which does a pass every render cycle to produce the final image.) Rather the shading effect is "baked" into the image as it is loaded. As a repercussion, this is free in terms of overhead on the render cycle. It costs some cpu time on the load/initialization cycle, and may become expensive in terms of memory consumption (since each shaded image needs to be cached in memory due the extreme cpu-time expense of cpu-based shading in real-time.) It is useful for creating black/white scene and rendering entities that can be customized via color (ie character clothing/weapons/hair/skin.) It cannot be used for highly dynamic shading variables (like lighting) very efficiently.

JevaEngine - Java Isometric Game Engine

Project Page:

Source Code Repository for JevaEngine - An Isoemtric Java Game Engine

JevaEngine is currently under very early development, and the source code is still being conditioned for user contribution.


JevaEngine is open-sourced under the LGPLv2.1 License:


  • Pure Java Implementation. No native dependencies, maximizing cross-platform ability.
  • Fully Scriptable. Scriptable scenes, events & NPCs (Scripts are written in JavaScript)
  • UI Is entirely skinnable and customizable - Jeva Core provides a solid infastructure for most general UI components.
  • Basic particle engine (implemented primary for attack\heal\projectile effects so nothing too fancy)
  • Fully capable quest system & dialogue system (dialogue can be complex with various pathways which effect any internal variables of the character (i.e. moral))
  • Most of the engine is entirely extensible - with logical partitions in implementation logic between Java and external scripts.
  • Map Editor, Dialogues can be contructed via freemind


You can take a look at some of the demonstration videos for jevaengine here.

How to Compile\Use

JevaEngine is fairly straight-forward to compile. As JevaEngine uses Maven as its build platform, the project is very portable accross various IDEs and dependency resolution is very easy.
