space harrier

Been a busy weekend, but I managed to find half an hour tonight to play with the Space Harrier code.
Refactored a few things for readability and general tidiness - shadows are now handled as a class rather than just a special case of Sprite, and die along with their parent rather than hanging around in spooky fashion.

OK, so it turns out I fail bigtime at maths :(

The code I had looked reasonable for the background and flying enemies, but trying to add some ground scenery - the trees and bushes - exposed just how broken it was.
I was hoping to have a demo available, but it looks like I need to go right back to the drawing board and actually read up on how 3D projection works...

Little something I've been playing with over the last couple of days. The latest Retro Gamer had a couple of mentions of Space Harrier, and somewhere along the line my brain went "hey! I could do that!"
So once I got back from Console Combat I thought I'd have a shot at knocking up a quick demo version...
