I just recently got to removing the more annoying glitches from my renderer, and sure enough, it works. I also added a FPS counter and realized that I was rendering at far higher speeds than I need(according to time() I was rendering at 300 FPS, but my clock might be a bit off). So by slowing down the thing a bit, I can now render at 30 FPS with low CPU usage, and even PNG alpha transparency becomes viable at a good speed!
And a quick note on what I'm working on: It's basically a 2d renderer that handles all the low-level stuff for you and offers you a high-level interface. Rather than manually blitting every sprite every frame, you just add a bunch of objects and do operations on them. I seriously think that game programmers shouldn't have to write their own renderer for every single 2d game, but I also couldn't find any good and lightweight rendering libraries out there that also had GUI integration. Well, that problem's solved :) Anyway, I'm thinking about releasing this code under a permissive open source license. Much of the code is focused around an FLTK widget, so it should be straightforward to integrate with an FLTK program. I currently use a wrapper for the images, which provide the Fl_Image functionality in an abstract way(that way you can use the same interface to work with e.g. SDL), but since the pure FLTK renderer is fast enough, I might just use Fl_Image instead. _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
