After quite a lot of code review and corrections (and some profanity), I completed the UI for Star-Hopper.
Here are the additions :
- The UI now displays directions for star-hopping.
- The next button also centers the object in the map.
- The skymap refreshes itself after drawing the path to star-hop.
- Double clicking the star in the UI list centers the object.
- Single clicking the star in the UI provides directions to star-hop to that particular star.
