Collision detection using 2D polygon outlines now works as described in the last posts. For debugging purposes, I added rendering for the polygons, which now show up around the ships as black lines. I’m not sure why they are a bit too large in the back part, but I assume that’s something that’s easy to fix.
I think the remaining days will have the largest impact on the look of the game, since pretty much all important gameplay related functionality is now in place. Tomorrow I will probably apply a texture to the planet, after that I’ll try to make an animated sprite for the shots. And the blue background will have to go soon afterwards.
