alice-teacher Program problem

[James Vanderhyde]

Emily, I have had good experience with the hidden event "When something becomes true" for this sort of problem. See the attached screenshots for a very simple world where a penguin jumps whenever it gets near a chair. You can get "When something becomes true" by creating a "While something is true" event and right-clicking on it to "change" it.

As is, the lifeboat does not ever recognize the shark, even if the shark is literally in the boat.  If you have a moment to look and get back to me, I would really appreciate it.  I have put in a screenshot of the bulk of the program.  My hunch is that one of his events is causing the problem, but still just can't figure it out.
