The projects there are:
First I wished these programs could be downloaded so I could try to figure
out how they work. Then I would know more to show my students. :)
I was searching for how to remove most of the turtles. I do not find a way
to remove all but t1 and t2. I realize now to remove all then hatch t1 and
t2 again. Then again I used clone to make more turtles, not he hatchturtle
If you know their name, you can say
ask [t3 t4 t5] [remove who]
With the following you can get a list of the turtles in page1:
show get "page1 "turtles
t1 t2 t3 t4 t5
It would be nice to have a command that does "set" difference like:
show diff [a b c d] [c b]
so you could do:
show diff (get "page1 "turtles) [t1 t2]
t5 t4 t3
ask (diff (get "page1 "turtles) [t1 t2]) [remove who]
ask diff (get "page1 "turtles) [t1 t2] [remove who]
And here it is... one possible implementation of "diff"
to diff :la :lb
let [lc ]
dolist [item :la] [
if not member? :item :lb [
make "lc fput :item :lc
I tried to do one of your projects from the text you have on the page, but
I had an error, that is why I said to be able to download would make things
easier. YET thanks for all you do for MW. I love doing what I do with kids.
I know they may not do wonder things, but I have 9 kids coming after school
working on their own ideas. The more I can show the more ideas they may have.
