Isometric map done

The coordinate transformation math for rendering an isometric map is always such a pain, but I got it working now:

ld34_isometric_map

The test map is just using some noise function currently, but the map system supports infinite terrain generation.

I’m probably aiming for the Jam, as I’m behind schedule a bit because I couldn’t work on the game full day yesterday (and spent way too much time redoing basic map rendering).
