JOT (i.e., minimal thing) modular multi-purpose game engine built in Java. JOT is intended to serve as a modular multi-purpose game engine for both academia, hobbyists, and or industry.

JOT was presented as a Videojogos (VJ 2016), Covilhã, 24 and 25 nov. conference article.

In windows explorer inside the intended cloning destination folder (**recommended C:\ **), mouse right click and in the explorer context menu and select Git Clone.

In the field URL paste https://github.com/g-amador/JOT.git and click the Ok button

Add an environment variable to the location of the jogamp operative system libraries, e.g., in the System Variable named Path add (assuming C:\ was where JOT was clonned):

C:\JOT\lib\jogamp-all-platforms\lib

C:\JOT\lib\jogamp-all-platforms\lib\windows-i586 (for 32 bits windows)

C:\JOT\lib\jogamp-all-platforms\lib\windows-amd64 (for 64 bits windows)

Open either the template in the templates folder or either demo on the demos folder in netbeans.

Build and set as main project.

Run demo.

-Options for either template/demo are in the netbeans corresponding demo/template assets/scripts/GameConstants.js, this file can be changed between runs without require recompiling of the project.

(UNDER CONSTRUCTION.)

Open either the template in the templates folder or either demo on the 'demos' folder in netbeans.

Build and set as main project.

Run demo.

Options for either template/demo are in the netbeans corresponding demo/template 'assets/scripts/GameConstants.js', this file can be changed between runs without require recompiling of the project.

JOT provides as is 4 working netbeans sample project demos, each supporting movement, model loading, direct rendering, FSP and help text, Keyboard and mouse I/O:

-Core template: a minimal example made solely with the Core layer, also includes 3D sound.

-Game World Demo: World/terrain generation demo build resorting to the framework, toolkits and core layers, also includes camera views.

-Physics Demo: Collision detection and light effects demo build resorting to the framework, toolkits and core layers.

-AI Demo: Steering behaviors and path finding demo build resorting to the framework, toolkits and core layers.

(other templates/demos exist but are currently broken thus will be available sometime in the future)

JOT is a game engine divided into layers, from bottom to top: Infrastructure, Core, Toolkits, and Framework.

Any layer component that resorts to an external library obeys to interface/abstract classes as expected by above layers. Each layer constituents can only use functionalities of the same layer or lower layers constituents. In order to replace a component in the engine, one might solely adapt the respective toolkit or additionally modify its lower layers.

These are the libraries/frameworks in which JOT layers and components were built on.

The minimal set of tools that can allow the classification of a piece of software as a game engine.

This layer includes toolkits, which are extensions to the core. There are toolkits for a number of purposes, namely artificial intelligence (AI), geometry generators, physics simulation, etc.

This is the upper layer of JOT. This layer aims at the following: first, to provide management of the application/game state and scene; second, to separate the game logic from its graphical application.

You are free to use and modify JOT as you see fit: to create your own templates/demos/games, to extend it, and to port it to another programming language. You cannot take the credit for making JOT! Please inform me if you either extend JOT, create more templates/demos/games for/with JOT, or port it to another programming language.

If you have any questions, feel free to e-mail me at gmail and ask away.

Good luck!
