The version on hackage adds quite a bit:
- Refinery units can now mine ore and transfer it to builder units.
- Builder units can now actually build units, if they have enough ore to do so.
- The scene is rendered using OpenGL/GLUT. Units are color-coded by player, with text describing their health and how much ore they have (except for fighters, which don’t carry ore).
I hope to keep adding to the project this week, though I haven’t decided what step to take next (don’t tell Joel!)
