It is very useful when creating a save system for games. This is code used to easily save and load classes to disk.
It is far from state of the art these days (when shadow maps rules), but should provide nice info for the curious. The shadow system in the engine is quite robust and can work on pretty much any mesh, something that shadow volumes usually don't.
A lot of work has gone into the system and is the result of a combined effort between me and Jens (who does all sounds) for several years. This is all the code that is used to play and tweak the sounds heard during physics interactions (bumping, sliding, etc). When it comes to interesting features, I think the following are the most prominent: Later parts are often cleaner and nicer, but the code is not without its share of quick-and-dirty-hacks.
This is especially true for some old and low level parts like the sound and input handlers which have evolved anything but gracefully. The transition from 2D to 3D and the fact that it was my first stab at a full 3D engine, makes the code quite patchy (and downright horrible) in places. After that only smaller fixes where made to it. The engine code was started in December 2004 and was actively developed until early 2008. This is engine that has powered all of the Penumbra games and it even includes the stuff used to create the 2D platformer Energetic. AI for the infected, GUI elements, etc are all missing, but all needed to implement them is present in the engine code (in case anybody is up for the challenge).įor my part, the biggest part of this release is the engine itself. It is also important to note that Penumbra: Oveture source will not run Black Plague or Requiem. These features should be farily easily to add though. This system is not the latest version in the Penumbra series and misses something like rotation. That said, it should have a few interesting bits, the major probably being the physicsal interaction system. This history means that the code is far from clean and as expected quite hackish in places. It also contains some code from Unbirth, giving it quite some history. The code for Penumbra: Overture is a continuation of the one used for the tech demo + some addition for the not so long lived Robo Hatch project. The thing that is free is the source code for the executable which is now released under the GPL version 3 licence. All assets (except a few that are part of the engine) are still under the same copyright as before. It has been in our minds for quite some time and now finally it has become reality: Penumbra:Overture and the HPL1 Engine are now open source! In case that is all you need to know, then head straight to:įor more information just keep on reading.įirst of all I would like to stress the fact that this open source release does not make Penumbra: Overture free in anyway.
