    Kyle's Game Engine

    Kyle's Game Engine

    Small OpenGL based game enegine

    This is a small project I have been working on in my spare time for enrichment. This used to compile for Sony PSP, but too much functionality has been added sense the last PSP build to compile. Development happens on a tiny netbook and my custom built gaming rig. The goal is to make it playable on the Netbook, and currently acceptable on a capable machine.

    Lightbringer (Rhye's Quest) Engine

    Lightbringer (Rhye's Quest) Engine

    A roguelike game engine/editor

    This is the engine/editor for a roguelike game called Lightbringer (Rhye's Quest). It is intended for programmers who want to quickly develop a roguelike game by extending, customizing and building on top of a large codebase that implements some basic and advanced parts of a roguelike game. The sources include: - Bare game engine with almost no specific features of the game, because they are my intellectual property; - Map editor; - Tile editor; - Default graphics tileset (tileset.grx). The sources DO NOT include: - Game maps; - Custom graphics tileset; - Source code for specific game features. IMPORTANT NOTE: Certain graphical features require the custom tileset which is my intellectual property, and as such is not included in the sources, only the default tileset is available. This means that you'll probably have to customize the tileset or the source code so that you'll be able to see certain graphics as they were originally intended to appear in the game

    LiquidFun

    LiquidFun

    2D physics engine for games

    LiquidFun is a 2D rigid-body and fluid simulation C++ library for games based upon Box2D. It provides support for procedural animation of physical bodies to make objects move and interact in realistic ways. You can write LiquidFun code in C++, Java, or JavaScript. LiquidFun is an extension of Box2D. It adds a particle based fluid and soft body simulation to the rigid body functionality of Box2D. LiquidFun can be built for many different systems, including Android, iOS, Windows, OS X, Linux, and JavaScript. For applications on Google Play that integrate this tool, usage is tracked. This tracking is done automatically using the embedded version string (b2_liquidFunVersionString), and helps us continue to optimize it. Since this is open source, you are free to remove the version string but we would appreciate if you would leave it in.

    Mandate Engine

    RTSish Game Engine

    The project is a fork of Glest Advanced Engine for the purposes of adding significant gameplay options, graphics upgrades and GUI upgrades in order to create an engine capable of playing a series of 7 games I wish to create. The 7 games are all based on this IP: Children of the Thousand Suns: The Unaligned Mandate Each game combines a few different genres from this list and others: RTS, TBS, RPG, Sim, City Building, Breeding, Management You can also make mods of various kinds with support for all the features my own games use and possibly more. It's open source and free obviously. Most modding is done through XML files quite similar to the ones for other Glest derivatives. There may be some good scripting support as well. Currently for fun I am creating a Majesty like to play with since Majesty 2 sucks and Majesty one doesn't support easy modding. Changed the homepage to the GitHub since the repository here is being difficult and thus doesn't contain the source.
