Amiga C Engine (ACE) is, as you can imagine, a game engine written in C for the Commodore Amiga. There are a few interesting games developed in ACE; ami-invaders, AMIner, Impsbru, OpenFire, Goblin Villages, CastleHack and Squared. There is a GitHub repository where you can clone or download the source and there you will find an introductory documentation. The documentation is incomplete but just enough to give an idea about how to start. The good news is that the project is active being the last commit four weeks old when I'm writing this,
After downloading the source or cloning the repo you can build the library using VBCC or GCC. The second one is the option I tried and it worked perfectly on my Linux cross compiling environment. Anyway, after seeing Aminer repository y followed their approach for my tests and used the source as a dependency, meaning this that I added all the source and header files to my Codeblocks project. In other words, I'm not using the compiled library.
