    openbor

    openbor

    The ultimate 2D side scrolling engine. NOTE: Moved to GitHUB

    Please note: OpenBOR has moved to GitHUB. Latest source and binaries may be found here - https://github.com/DCurrent/openbor OpenBOR is the open source continuation of Beats of Rage, a Streets of Rage tribute game originally developed by Senile Team. In the years since it has grown into arguably the single most powerful two dimensional sprite based engine in the world and certainly the most versatile. While intended to allow creation of side scrolling beat em’ ups like Double Dragon or Final Fight, the engine is also capable of replicating Shumps, RPGs, platformers and the like. A built in scripting engine allows authors to take it even further, making imagination the only real limit. See www.chronocrash.com for more details and to download the latest versions.

    Skynet

    Skynet

    A lightweight online game framework

    Skynet is a lightweight online game framework which can be used in many other fields. Skynet is a lightweight framework designed for online game servers. Although from the feedback of the Community , it's not limited as a game server framework. On the Uses page, it shows a few projects that have used or currently using Skynet, but there are way more projects than listed. And welcome to be the next user. For Linux, install autoconf first for jemalloc. For FreeBSD , use gmake instead of make. Skynet now uses a modified version of lua 5.4.2 for multiple lua states. Official Lua versions can also be used as long as the Makefile is edited. With Socket API and SocketChannel , which makes it easier to implement socket pool and reconnect, you can use Skynet to call socket even asynchronously. Skynet doesn't force a specific protocol, you can come up with your own design.

    Permafrost Engine

    Permafrost Engine

    An OpenGL RTS game engine written in C

    Permafrost Engine is an OpenGL 3.3 real-time strategy (RTS) game engine written in C, designed to capture the feel of classic RTS titles while incorporating modern rendering and AI techniques. It uses a programmable pipeline with features like skeletal animation with GPU skinning, Phong lighting, bump mapping, terrain texture splatting, water rendering with reflection and refraction, and skyboxes. The engine is tailored specifically for large-scale RTS gameplay, supporting huge maps, efficient batched rendering, hierarchical flow-field pathfinding, formation movement, boids-style steering behaviors, and GPU-accelerated crowd simulation. It integrates tightly with Python 2.7 for scripting, exposing engine internals to Python and even allowing serialization and restoration of the entire Python interpreter state for robust save/load systems.
