So after spending the afternoon on it, I've linked in the basic player stats, one of which is the amount of gold that the player is carrying. Now, thanks to the new code, players can go up to chests in the dungeons and take the gold out of them, putting it into their inventory with a nice little "coin jingle" sound effect. It also handles permanence in the chest contents (you can leave stuff in a chest, go away, come back and it's still there) which sounds like a really obvious thing, but in a procedurally generated game it can get a bit zany.
Anyway. The next thing I'm going to handle is the full player inventory, including bits of armour that the player can put on! So more on that over the coming days!
