The blob of sauce is embedded in the playfield. The blob of sauce lives in
a holder. It is embedded the playfield. I make a copy of it each time a
blob of sauce is fired at the pizza. When I check any of these copies,
they are also embedded in the playfield.
I have also seen some odd behavior with the movement of the fired blob of
sauce. I was trying to make it take a saw edge path from the sauce can to
the pizza. I started it off with a direction of 135 (moving from left to
right). After moving 25 times, I would change the direction by -90 or 90
every other time. When changing the direction by 90, the blob would jump
to a new location (down and back from where it was). When changing by -90,
it would work fine.
Ordinarily I would think the problem would be with my code. But I have
been programming in Smalltalk (VA Smalltalk) for many years and this code
is very simple, so it seems like something odd is going on.
I have dropped the saw pattern idea and adjusted the positions to work. I
hard coded points where I was trying to use values from existing objects.
It works but it is not as general as I would like. If I move anything, the
hard coded points have to be fixed.
