I can't believe that nobody actually requested treasure chests.
We only have a humble wooden box to 'hide' treasure in.

A real dungeon has treasure chests scaling from humble wooden boxes to majesticly decorated chests.

I'm pretty sure you can do it by scripting it. I'm still new at this and still learning, so this example is probably not 100% accurate. Not too sure about hook names, but in general something like this: function revealWallText () spawn('walltext', levelcoordinate, x-coordinate, y-coordinate, facing)...
