An Open-Source Retro Game Engine.
Rengine is intended for Retro-style games. The word style is used because while games running under Rengine will look retro, they are by no means limited to the CPU and memory constraints of the computers of yore.
Rengine also includes a 2D level editor for editing maps.
- The home of Rengine is at https://github.com/wernsey/rengine
- Documentation can be found on the Rengine wiki page on GitHub.
Rengine is distributed under the terms of the MIT License, which means that it can be used for just about any purpose. See below for details.
It uses SDL for cross-platform operation.
Rengine implements a state machine where the parameters of the states are read from a configuration file.
Some states simply display a static screen and waits for user input, while others invoke a scripting engine to draw graphics and control the game.
Rengine is dependant upon these 3rd party libraries. The version numbers in parenthesis are the latest specific versions that rengine was built and tested against:
