Open Rodent's Revenge

C++ remake of the famous Microsoft game "Rodent's Revenge" (1991) made with Qt, SFML and MicroPather.

Download link for the 0.7 version for Windows (original link).

• Open Advanced War
• Space Carrier

I have absolutely no rights over the original property and multiple alternate sprite sets are included that completely replace the reproduced sprites.

Screenshots (0.7)

Features (0.7)

• Same gameplay as the first levels of the original game : you (the mouse) must move blocks around to trap cats which then transform into cheese after a certain amount of time. The cats can move diagonally, and will compute a path to you if one is available (A* algorithm). Otherwise, they will just move around randomly.
• Level editor : place different blocks and the mouse's starting position and save your own levels in a simple text file.
• Levels of any size (within reasonable limits) with sprites rescaling or dynamic screen size (launcher option).
• "Modding" system : replace any sprite with a new one and combine your modification with others ; the loading order will determine which file to use. You can see an example of such a modification in the gameplay screenshot above where the lives display uses hearts instead of mouses ("zelda" mod).
• Game launcher : a simple launcher that can be used to configure a game or a level editing session (uses the command line arguments internally). You can also choose different mods to use with convenient priority reordering. Your options will be remembered.
• Tiled Map batch rendering for better performance (one drawing call for each sprite type).

History

The latest beta version (0.7) was released in 2010 and consists in two different programs : a launcher made with Qt 4 and the actual game made with SFML 2 and Micropather. You can download a Linux build or older versions of the game on the original Sourceforge project repository. All versions included (mostly 0.6 and 0.7), this game was downloaded more than 40 thousand times.

I started a rewrite for 1.0 but wasn't able to finish it at the time. This version uses Qt 5 and SFML 2 in order to have a single game window. Note that this would most likely make a port to mobile platforms pretty straightforward.

This project is currently incomplete and somewhat outdated (limited modern C++ usage), but anyone is welcome to build upon it.

o2r's Issues

Path problems?

Whatever I do, I always get:
Fatal Error:
One or more resources are missing.
Check if folder: 'data/base' is present.

I've set "Game -> location" to the O2R folder, and tried pointing to a different level .txt, but the same happens. I've moved the folder to the root of my drive, and same issue. I tried editing settings.ini manually, but same issue again. I tried windows style path with \ instead of /, same problem and it messes the launcher. Deleting settings.ini gets it recreated, but same issue again.

Running Windows 10, and just downloaded the release package, I don't have Qt libraries installed apart from the files included; not sure if a missing dll is the problem.
