Re: Etoys and Connectors package programming...

Lawson,

Also with what object did you associate the "self hide" script?

When you "tell all outgoing connectors" to run a script the script that
gets run is associated with the connector (not the object connected at the
destination of the connector).

Now if you use "tell all succesors" then the script that is run is that of
the connectors destination/

So in the example below:
*Rectangle:script1* - Will cause *Arrow2:script1* to execute, causing the
ellipse to change color
*Rectangle:script2* - Will cause *Ellipse:script1* to execute, causing the
ellipse to turn by 5

Hope this helps,
Stephen

To some of us, writing computer programs is a fascinating game. A program
is a building of thought. It is costless to build, weightless, growing
easily under our typing hands. If we get carried away, its size and
complexity will grow out of control, confusing even the one who created it.
This is the main problem of programming. It is why so much of today's
software tends to crash, fail, screw up.

When a program works, it is beautiful. The art of programming is the skill
of controlling complexity. The great program is subdued, made simple in its
complexity.
