Caster History

Much like Amit Singh and his Hanoimania, I regularly attempt to port my friend’s game Caster to as many platforms as I can. Because of some good language and API choices upfront (C++, OpenGL 1.X, SDL, etc…) the Caster codebase is very portable. That portability combined with its relatively humble (for these days) performance needs has lent the (currently still unified) codebase to easy porting. This multi-platform journey began many years ago before Caster was even released. Caster was still in early development when Mike approached me with the idea of maintaining a concurrent Mac build. At that time Macs had not yet moved over to x86 processors and so the most difficult part of the process was reverse engineering Valve’s Half-Life model format (which Caster uses for animated character models). The Half-Life model format was a binary, in-memory format utilizing offsets which meant that while loading it was quick and simple (just read it into memory, no processing whatsoever) it was unfortunately dependent on little-endian byte order to work. Other than that and a couple of other issues, the Mac port was really straightforward. So before release, Caster was solidly supported on both the Windows and Mac platforms. After release another guy helped out with the Linux port of Caster and so at that point we now had the major desktop operating systems covered. Over the years we added slightly different versions for the desktop platforms to adapt them to specific distribution avenues like Steam and the Mac App Store. The first port that required major reworking was iOS. That adventure was chronicled in my post Caster for iPhone: A Postmortem. Mike and I had the opportunity to give a presentation about what we learned at GDC Austin ’09. Later on as the Android and webOS mobile platforms took shape, I started to look into porting Caster to those platforms as well.
