Work In Progress: An engine skeleton.
(What do you mean by skeleton?) This will be a set of modular structures organized as an engine. The code needs to be tied together in a game as the user sees fit. This just has a great amount of the managament strutures and other things done off the bat when wanting to make a game similar to the one this was intended for. You need to configure this into a proper project and compile from there.
Orginally done in C# with the monogame framework along with bepu physics, I'm now doing it in C++ with SDL, and Boost so far with some basic OpenGL. (Still in the process of porting what was done in c#). I will eventually add a physics engine/framework and 3d renderer (undecided on which).
These include things related to Camera, Display, Input, Interface, State, and Asset management.
Note: This is dead. I'll be working on something else in the future instead.
