Day 4

My original dungeon code was written with a text user interface in mind. Now that I am using SFML I needed graphics.  I settled upon Surts' Lovable Rogue tileset from Open Game Art.  It is distributed as all the tiles in one PNG file so I had to find out how SFML handles making sprites from pieces of an image.  It turns out to be fairly simple.  I can now display my dungeon and a player in it.  Except it looks odd.  A short investigation reveals that, embarrassingly, I'd got the x and y coordinates mixed up in my draw function.
