This looks very nice, congrats! I'm especially interested in the physics
and character controller part, because I'm currently developing a
character controller myself, but just a sphere character in a static
triangle world for now.

Finding a robust and fast sliding algorithm for sliding a sphere along
triangles in a given direction seems to be the hardest part. I'm
investigating two approaches, which can be simplified to:

1) move until we hit any geometry, compute new slide direction, repeat
2) move first, then project the character out of the world geometry

Both approaches work reasonably well, but there are scenarios where
they don't work so well (mostly pathetic scenarios). I'll
definitely look how you solved the problem and maybe tinker with your
physics code :)



I took rather idiomatic approach: move, detect collisions, generate 
contact points, then solve them iteratively. Sliding is obtained 
somewhat automatically.

Nice, graphics and physics look impressive in the demo video.  If 
you ever want to try and get it on Android, let me know if I can 
help.  I'll have a build of the ldc cross-compiler up for 
download in an hour, will be announcing it soon.

Great looking game, nice work. Are there any plans to distribute

I visit your blog time to time and sometimes download demo. 
Really glad to see improvements. Definitely will wait for the 
release to play.


Did not know about Inverto, should check it out too.

They already exist as separate libs:
https://github.com/gecko0307/dmech
https://github.com/gecko0307/dgl

DGL (graphics engine) is currently falling behind from the game and may 
contain bugs, but I eventually update it.

How have it been to work with the GC?
Reddit it! Maybe with an writeup?

I tried to fully avoid GC, using my own malloc-based allocator. This 
lead to the fact that the code is not very D-ish, but it proves that 
there's perfectly possible to write real-world GC-free applications in D.
