Inform's World Model and the Player - cheat sheet

I remember I used to fall foul of using the wrong adjective when I was checking if the player ‘had’ some object about their person in a particular situation. Depending on whether it’s in your inventory, or you’re wearing it, or it’s part of you, or part of something in your inventory, or in a box in a bag… sometimes I’d write code testing for it, and I’d use the wrong test.

To this end, I wrote this cheat sheet to nail down which things are where (this’ll make sense when you look at it). I made it back in 2011, but I just tidied it this morning and thought it would be a good share.
