Booyah! I may be overly excited for this, but cut me some slack, I'm pretty new to this.
So yeah. Pathfinding. Each time the map changes, each hero's pathfinding component will recalculate costs and paths to each cell. That shouldn't happen often. In fact, far more often the cursor will move and have to show how many days it will take to reach the cell it's hovering over.
The hero, whom I shall dub Kazimir (or Kaz for short) from now on, cannot yet move. That's the next step!
These posts may be cutting the development a bit too thinly, but I think it's going to be great seeing how far this game has come in the end, and having all these screenshots from the very beginning.
