This makes a pretty pinwheel:
Shoes.app :width => 500, :height => 500 do
animate 10 do
rotate 7
line( 100, 100, 200, 200 )
end
end
At first glance I don't understand why. The first time through the
"animate" loop, the line is rotated 7 degrees from where it would have
been drawn. The second time, it is rotated 14 degrees, and so on.
Where does that stored rotation live? Is there a "rotation value" in
the slot, which affects everything that is drawn within it? That
seems to be the case. And "rotate" doesn't *set* that rotation value,
it *increments* it? That's counterintuitive to me. Is there any way
to "get" that value? To reset it to zero?
Trying this I found that that rotation value seems to be specific to
the slot:
Only the first slot's contents are affected by the "rotate."
I guess a question to _why -- is it a bug that "rotate" adds to
previous "rotates" in the same slot? Or is that intended behavior? It
sure seems weird to me.
