Well, that's what I thought. In the words of Randy Newman, maybe I'm doing
it wrong. In my morph class I have:
xDir _ 0.
yDir _ 0.
ActiveHand addKeyboardListener: self; keyboardFocus: self.
which is the only reason it works at all. In my keydown method, I have:
(evt keyCharacter = $W) ifTrue: [xDir _ 0. yDir _ -1].
(evt keyCharacter = $S) ifTrue: [xDir _ 0. yDir _ 1].
(evt keyCharacter = $D) ifTrue: [xDir _ 1. yDir _ 0].
(evt keyCharacter = $A) ifTrue: [xDir _ -1. yDir _ 0].
I put in the halt just in case the code was wrong somehow, but if I click
on any text window, messages stop going to keyDown for my morph.
