Now when you open the chest, the game tells you that you've received 29 gold coins. This is a lie, it will also tell you this if you close the chest the open it again.
To me though, it feels like progress!
I rejigged my mouse user interface, so it uses a state system (covered in one of the programming for monkeys tutorials). There's a message state that currently displays a label. At some point I'm hoping to upgrade this to a text box.
Also I'm hoping to actual give the player something, move some bytes around. No matter what the message might say, you're never actually given any gold coins :(. I also want to empty the chest. And perhaps even fade out the message. Yay me.
