After quite a conversion process, I've successfully converted the c++ GDC 2006 2D Physics demo to D. Original: http://www.gphysics.com/archives/18 D Version: http://www.dsource.org/projects/arcgames/browser/trunk/physics/demo.zip?format=raw Use keys 1-9 to switch through demo, and space bar to launch the 'bomb'. It also comes with a public domain red black tree implementation that seems to work. The author of http://eternallyconfuzzled.com/tuts/redblack.html told me he is going to add a license page that says all the code on his pages are in public domain. Special thanks to Christian Kamm for helping me track done a bug. ~ Clay

I see some kind of delta timing with the "dt" global in main.d, but it's set to a constant 1/60, and in windowed mode on Windows, it'll try to update the screen as fast as possible, so the frame time will be something other than 1/60 of a second. Is there maybe a way to force it to run in fullscreen, so it's limited to the refresh rate? I'd recompile it but I don't have Derelict, so..

If you have the D compiler and build, all you need to do is 'build main.d -Rn -full -release -O' to build it. Throw in an SDL_Delay(40) in the main while loop if you want a quick solution, or add a 'flags = SDL_OPENGL | SDL_FULLSCREEN' to the SDL video flags for fullscreen in main.d around line 668. Within the next year or so I'm going to integrate this into my 2D game library ( http://arcgames.dsource.org/arc/arc/time.html ) which has a delay timer that will delay the main loop as needed to keep a constant frame rate. I need to figure out how to add circle shapes and eventually polygon shapes, however the author says at GDC 2007 he'll put more shapes in his demo. There is also a java port that supports circle and line shapes http://code.google.com/p/phys2d/After quite a conversion process, I've successfully converted the c++ GDC 2006 2D Physics demo to D.

Though strangely putting it in fullscreen didn't help. Apparently, there's a way to make SDL wait until a vertical retrace until it updates the screen, using SDL_DOUBLEBUF for the video flags and SDL_Flip() at the end of the loop, but I tried that and that didn't help either.

The version of SDL that Derelict (or at least the Derelict that comes with Clay's demo) is 1.2.0, and SDL_GL_SWAP_CONTROL is only available starting with 1.2.10. Have to do some more fiddling this afternoon..

It was also missing SDL_GL_ACCELERATED_VISUAL. The Derelict trunk has been updated with the fix.
