Re: [Squeakland] How can I make an object to follow a path?
by Scott Wallace 15 Feb '05

15 Feb '05

Hi, Suna, There are various ways of making an object behave in a manner that could be described as "following a path." (1) Here's a very simple way, which *might* suit your needs: Bring up the halo on your object, and look in the "extras" submenu of the halo menu; you'll see three "path-related" items. When you choose "define path", the cursor changes to a special "path-defining" cursor, and you're invited to drag your object in the path you wish it to follow; release the mouse button when you're through. You can then get the object to re-traverse that path any time by choosing "follow existing path" from that same menu. Or, to follow the path programmatically, deploy the "follow path" tile, which you'll find in the "miscellaneous" category of a Viewer. (2) If the path can be defined by a series of points in the x-y plane, another approach is to write a series of ticking scripts, each of which is in charge of getting the object from one of the reference points to the next; each such script, once it has accomplished its purpose, "stops" itself and starts the next script in the sequence to ticking. Incidentally, the ideal place to post this kind of question is the Squeakland mailing list. If you're not yet a subscriber, I encourage you to join :-) If neither of the above suggestions fulfills your needs, please describe what you want in more detail, and most likely you'll receive more suggestions from readers of the Squeakland list.

It was a strange problem but I resolved it. I had to reboot after uninstalling, then reinstall. Erik Nauman Middle School Technology Coordinator The Hewitt School 212-994-2610

animation, holder
by Randy Heiland 14 Feb '05

14 Feb '05

Hi Squeakers! I just went to Squeakland, downloaded updates, and was experimenting with creating a simple animation - per the "Powerful Ideas..." book and Squeakfest tutorial. It seems there is no longer a "Holder's playerAtCursor" tile in a Holder's viewer. Is that true? What do I do? I was pleased to see that dropping frames into the Holder is no longer plagued with the annoying problem of having to put the cursor in "just the right position". In fact, it seems that the behavior of a Holder is more dynamic than what I remember from Squeakfest, in that it resizes according to how many frames you drop in and allows for easy rearranging of frames - or maybe those features were already there and I didn't realize it. Although I didn't really push it, I'm wondering, if I drop in so many frames that the Holder exceeds the size of my world/screen, will the Holder automatically reveal scrollbars? (It would be nice :) Thanks, Randy

Alice?
by Bob Irving 14 Feb '05

14 Feb '05

I'm interested in whether the Alice implementation in Squeak is on a level that is useable by middle schoolers. I've been searching the net and haven't found anything on that. I'd also like to find a very elementary tutorial on using same.

can't see local disks
by Randy Heiland 14 Feb '05

14 Feb '05

All of a sudden, when I do a (hold down) 'FIND' -> find any file (or, find a project (more places)), I don't see my local disks, e.g. c:, d:. All I see is the list of 8 other places: <my squeak folder>, Bobs SuperSwiki... local-bss. Just a couple days ago I *was* able to see/grab files on my local disks. Any explanations? Running 3.8.5976, update 387. Thanks, Randy

resizing objs in playfield
by Randy Heiland 14 Feb '05

14 Feb '05

I have sketch1 and sketch2 which I want to 'joint' into a single object (so that I can resize it and have both of them be resized). I thought perhaps putting/embedding each of the sketches into a playfield would allow that, but resizing the playfield doesn't resize the sketches themselves. Suggestions? Thanks, Randy

Can I/how can I change an existing variable name and have that name change propagate throughout all scripts using that variable? Thanks, Randy

Hello, Our Squeakland server encountered some errors recently with AOL mail. If you are an aol user and tried to send a message to this mailing list in the past few days you might wish to send again. We believe we've remedied the situation between Squeakland and AOL. -- Kim

TTCFont problem on Linux
by Randy Heiland 09 Feb '05

09 Feb '05

I thought I'd try to read in my project (built on Windows) using my Linux squeak image and it says: Reading an instance of TTCFont. Which modern class should it translate to? Just wondering if this is some known problem and, if so, is there a workaround? Using 3.2.4913, update #140 on Linux. Thanks, Randy

RE: [Squeakland] merging projects
by Dreyfuss Pierre-Andre (EDU) 09 Feb '05

09 Feb '05

Hi, An other way to put an objetct in an other project, dicovered by a student, is to drop this object on the Button representing the second project. You see the words 'I got it'. Then wait until the droped object comes back at his place. Go to your second project (by clic on the button) and you'll find the droped object in it. The complete process is: - load project 1 - From project 1, load project 2 - Go back ti project 1 (button previous in the navigator flap) - Now you can put any object of project 1 on the button for project 2. - Go to project 2 by click on the same button. - In project 2 you have now all the objects sent form project 1.

Load both projects, and move objects from one to another by putting them into a shared flap. - Bert - _______________________________________________ Squeakland mailing list Squeakland(a)squeakland.org http://squeakland.org/mailman/listinfo/squeakland
