[squeakland] Bananas in a Box questions

[Harness, Kathleen]

Randy,
The project in the link below works for me, maybe we are counting different bananas? When I click the go button the bananas move around and if I can catch one and drop it into the box, the count increases by 1 and will do so as each banana is put into the box. A banana that just moves over the box is not in the box until it is picked up with the mouse/cursor and dropped into the box so that it is contained there and no longer can it roam the rest of the world.

There isn't a test in this project, that would be too hard for young students to make, but not to play. The script has  forward by and turn by tiles. The tool that is counting is a detailed watcher for the playfield's collection and it does the work of counting whatever is in the playfield. It counts whether the script is ticking or not, drop a banana in or, the title, and the counter increases for each object.

Did you have a chance to look at the scripts in the student's Catch Games projects? They were made by 2d-5th grader students last year.
Regards,
Kathleen

Thanks for all this help, I initially set out to count the number of bananas that get into the box.  To get my counter into 'all-scripts' I needed to click the timer.
Then I'll need to stop each banana if it enters the box or somehow just count +1 for it's entry into the box.
I realized I was thinking too complicated for a level K program.
I'm not sure what 'count' is meant to show
http://etoysillinois.org/library?sl=1656
Run this, the box's count stays at 0.  The logic I'm using initially is, from the box perspective,
if the box's color sees the banana's color, increment count.
What happens is the counter increments many times, as long as the banana and box colors are touching for each time click.

So, I guess a more basic question is - what's the counter at the bottom of the box supposed to be doing...my version I'm running the count stays at 0.

THanks again

Randy

Hi Randy,
The counter under the box is from the playfield's collection tiles and is a detailed watcher. I renamed it: box.

If you want to count the bananas that are not in the box so children can see changes from one place to another and do a little addition too, then put the bananas in another playfield from Supplies, open its halo, choose the Viewer tool, click on the basic label to open the category menu and choose playfield's count. This way it will be clear that it is only bananas that are being counted. If you use the world's collection counter, then it will count everything including the title, playfields,and the stop step go button etc.

There are lesson materials that go with the project but you have to scroll down after choosing and before you download or open the project.  I have had students make projects like this and you can see theirs if you click on the Library Collection tag:  Catch Games. I think theirs go too fast but the kids liked them and it was their decision to make.

Thanks for your comments and questions I look forward to hearing more about what you and your students are doing with Etoys.
Regards,
Kathleen Harness

Hi Randy,

if I understand correctly, you are saying, that "all scripts" isn't running all the scripts? To have a script get started with the "all scripts" button, this scripts needs to be in the state "paused". You can see a short info about this in the balloon-help, which appears, if you move the mouse over an object and wait a little.
To change the state of a script, click on the field on top of the scriptor (in the example below it says "normal". Click and hold, then you can change the state.
