    KonsolScript and Game Engine

    KonsolScript and Game Engine

    Free and Open Game Programming Language for Windows and GNU/Linux

    KonsolScript is a free and open source, scripting language primarily intended for 2D games development. KonsolScript Development Team believes that the unavailability of games on GNU/Linux desktops is one of the major concerns why people keep using unauthorized copies of proprietary OS over GNU/Linux and that is something the Development Team is ought to address – we are doing our part to help promote GNU/Linux as a viable gaming platform for desktops both for Game Publishers and Gamers. The whole Game Development Kit is suitable for teaching 2D game programming. The end goal of this project is to have a common gaming platform for Windows, GNU/Linux, Mac OS, including mobile platforms like Android where any newbie can learn how to make his game/animation etc. A lot of work has been made and a lot more is to be done. It might need to hire programmers to make an engine for Android, and Mac OS, then some in-house testers for stability among these platform

    IsoRealms Spindizzy and Isorealms Engine

    IsoRealms Spindizzy and Isorealms Engine

    An isometric arcade-style game of skill, puzzles and exploration

    You are cartographer for undiscovered worlds; your task is to explore and map all areas of the recently discovered strange dimension of Hangworld. In order to complete your task, you take control of GERALD. However, fuel is expensive and funding can only be supplied as long as progress is being made, so it is vital to explore new areas and recover jewels. Spindizzy is a remake of the 1986 classic computer game of the same name, originally developed by Paul Shirley. The remake features true 3D OpenGL graphics and runs on a custom-built engine called Isorealms. The Isorealms engine features a complete content creation toolkit for modifying and extending Spindizzy, as well as offering the opportunity to create entirely new projects from scratch. Isorealms content creation tools are aimed at users of all experiences, from those who simply want to build new worlds to those who want to take advantage of advanced features such as Lua scripting and custom asset importation.

    Vanda Engine

    Vanda Engine

    A free 3D game engine to create games and realtimes scenes for Windows

    Vanda Engine is a free and open source 3D game engine for Windows. I'm developing this game engine for years to help the students and other enthusiast learn game engine programming and develop 3D games for free. While giant companies are building game engines with huge budget and a lot of manpower, I'm developing this free 3D game engine alone with no budget. I have published step by step tutorials about Vanda Engine, 3D tools, and COLLADA format: https://vanda3d.org/tutorials/ Please follow Vanda Engine on Facebook to be informed about what I'm doing: http://facebook.com/vandaengine Check out Vanda Engine website to see how Vanda Engine is getting work done: https://vanda3d.org/ It will be appreciated if you donate to this project so I can buy required software and books and hire people to produce free 2D and 3D assets and educational videos and tutorials for this game engine: https://vanda3d.org/donate/

    oge2d

    Cross-platform 2D game engine

    Open Game Engine 2D is a full features and cross-platform 2D game engine. It aims to help developers to create 2D games with only flat files (such as ini and script files), so that games could be written once and played under any platform supported. This engine is a pure 2D game engine written in C/C++. It is base on SDL and AngelScript. So, it also aims to run in any platform supported by SDL and AngelScript, such as Windows, Linux, MacOS, iPhone, Android, Windows Phone, Symbian, NDS, PSP... But, in current version, the engine only supports the following platforms: Windows, Linux, MacOS, Windows Mobile, Android, iPhone.

    ALRDR 2.0 demo

    ALRDR 2.0 demo

    The second demo of my game engine.

    Started when I was 16, still not ended, here is a demo of the game engine on which I work for more than 1 year. It's my first game project, so I decided to make it easy, by creating my own game workbench (a friend is making the MapEditor, I'm doing the rest), including the game engine, render engine, graphics, programmation, syntax ect. Don't wanted especially to share it, but friends wanted to play on it, so I will just share the .exe here. The source will come maybe later :)

    AlphaGenesis

    A retro style video game engine for RPGs and adventure games.

    The AlphaGenesis project aims to create both a high quality, strategy oriented, SNES style turn based RPG, and an engine for building top down perspective 2D games. I have been writing the engine in my spare time over the past few years. It currently contains a game client and map editor. It is mostly complete as an engine, but there are a few features I still plan to add. AlphaGenesis is being developed with the intention of being cross platform and easily extensible, so that people without much programming experience will be able to add content to games with little effort. I am pushing to get a playable demo out by the end of January 2014.

    Bad Monkey Engine

    Bad Monkey Engine

    A truly extensible cross-platform game engine

    The Bad Monkey Engine is designed to function as the core engine for game development. Its architecture fully supports cross-platform game development by abstracting all platform specific code into general purpose utility classes. The primary platform is WinTel with parallel development occurring for Unix-based operating systems. Console-based platforms are not available yet due to the restricted nature of the APIs for these platforms.

    Faber Ludorum

    A DirectX 9 C++ game engine

    Faber Ludorum is Latin for "Builder of Games" or "Maker of Games." Faber is intended to be a simple game engine largely for my own education in game programming, but it may be useful for others if all goes well. It will initially support DirectX 9, but support for more modern APIs may be added later.

    G2

    A generic 2D engine for any kind of game

    This game engine uses the power of C++, OpenGL, and OpenAL to provide highly-portable, object-oriented code for programming a video game. Rather than tailoring to a specific type of game, the engine focuses on the fundamental components. It covers audio, graphics, controls, and data flow. With G2, developers have everything they need to create a 2D game without the need of expensive SDKs.
