alice-teacher Scope of world booleans

I just want to say how exciting it has been to teach all varying student
abilities in middle school programming concepts through Alice. Just sending
a big thank you for this incredible program.

Cheers,

Deb Harding

boolean variables to retain their scope and be useful in IF structures on
dependent objects. I can drag local boolean variables directly into the IF
condition, but can't drag world booleans into there. This makes setting up
game state variables more tricky than expected. Note that setting world
functions that simply return the variable state work as expected, but I'd
rather leave encapsulation until much later.
