Re: Morph Drop Shadows

[Newbies] Morph Drop Shadows

HI David H. Shanabrook,

As Bert says the trick is to move the morph w/o
lifting it. 
One general way to do that with any morph is the brown
halo handle.

The other is to create a morph that behaves the way
you want.
I had started some work which I had hope to apply to
moving block puzzles.

I wrote a little about it Here:
http://lists.squeakfoundation.org/pipermail/squeak-dev/2007-May/116371.html

And posted my work in progress code to bob's super
swiki

http://209.143.91.36/super/728
MovingPiece-wiz


The codes in the form of a 3dot9 project.
Load the project and look at the change set for it.


Also earlier related work on puzzleboards modified a
pasteup morph to prevent overlapping pieces:

Puzzleboards

The code is in both project form (for an old 3.7
squeak) and as change sets. The change set should work
in 3.9 and probably a recent 3.8 (if they fixed the
bug mentioned)


You will need to adapt it to apply to pentomino's

Hth.

Yours in curiosity and service, --Jerome Peace
