New subject: Car and Steering wheel demo and Squeak-DEMOS

27 Aug 1999

      You should open a new morphic project and make sure no windows are open in
it.
The problem with event recorders like this is that they play back a sequence
of mouse and keyboard events, without regard to things in the playback
environment that can get in the way.
I had a similar problem and it turned out that the first mouse click that
was supposed to open the menu happened over top of something else I had open
in the window. Once the recorder gets off to the wrong start, the result is
essentially what you describe.

Using 2.5 and Windows 95 this just opens a few menus and shuffles them
around - no car or steering wheel insight!
I carefully positioned the RecorderMorph in the top left. I guess the
co-ordinates are misaligned?
Looks promising though,

I've placed a recorded demo of creating a car and string
wheel and then
...
hooking them up at:
http://www.advantive.com/squeak/car.tape
Instructions:

Get a fully updated standard Squeak 2.5 image
Start it (don't resize anything).
Create and Enter a Morphic project
Open an EventRecorderMorph and position it precisely in the
top left corner of the screen (aligning the pixels with the top

left)
...

Select "readTape" and enter your downloaded copy of the above file

If I use the Windows version the recorder does not read the file (I
placed it directly
in the squeak directory). So I commented out "(FileStream
isAFileNamed:
fileName) ifFalse: [^ nil]."
in the EventRecorder>>readTape: method. Must be a bug or a wrong
location, because
FileStream isFileNamed: ... always returns false, so the
method returns
nil.
After commenting the line out it worked fine.
...

Select "play" and watch

YEAHHH... COOOOOL
After editing the created script textually (selecting "edit this cript
textually" on the
scripts name) I saw what Scripting really is about: visually composing
methods
with players. Thank you Stephen and Bob for enlightening me.
I think morpic tapes are a good way to explain morphic stuff.
We should
create more tape
files and put them on a swiki page! Squeak Central can create a
Morphic-PWM-9 with
Scamper showing this page and if a beginner clicks on one of
the listed
tapes scamper can
open the recorder to play the demo. So we can create Tape-DemoWithMe's
on the swiki page
and so it's much easier to learn Squeak.
What do you think about that ?
Bye
