In the last part we added a field of vision to limit what the hero would see at any given point in time. In this post we will be making it so that our hero remembers the parts of the cave that have been previously visited. If a tile has been visited before but is not currently in the field of vision, it will appear however any entity that may be on the tile will not! These tile will also appear in gray in order to show the current field of vision.
The results after this post can be seen here.
