[Etoys] Embedded morphs have incorrect x and y when their owners are flexed.
by Jerome Peace 05 Nov '07

05 Nov '07

Embedded morphs have incorrect x and y when their owners are flexed. See my note in: 0006747: [Bug] How to make a dizzy Morph Bounce http://bugs.squeak.org/view.php?id=6747 Basicly I have started to examine issues dealing with embedded morphs and rotation. I was looking for much more complicated bugs but this simple one demostates the problem.

It's here: http://dev.laptop.org/~bert/ole_nepal/ However, your icon does not get colorized (as you can see in the PNG), it is missing the fill and stroke entities. It must use an outline and a fill, so you need to manually edit the file to assign the entities.

[Etoys] simplifying basic category
by subbukk 03 Nov '07

03 Nov '07

Hi, The current slots/commands in basic category is part turtle geometry and part cartesian geometry. I recast the viewer to include only turtle geometry primitives in basic to make etoys easier for children who are yet to develop intuitive understanding of co-ordinates. Why present two systems when one is sufficient? I would have liked to make "pen down false/true" to "pen down/up" but I am yet to figure out a simple way to get Boolean slots to support arbitrary strings/symbols instead of just true/false values. throwing it open for discussions, Subbu

[Etoys] [FIX]ColorPickerMorph tracking gray
by Karl 02 Nov '07

02 Nov '07

I noticed that the little circle tracking the picked up color was misaligned on grayscale. I changed the hue value from 0.0 to 240.0 and it works better.

[Etoys] [BUG]TextMorph avoid occlusions
by karl 01 Nov '07

01 Nov '07

When a TextMorph accepts drops and you try to select avoid occlusions in the handle menu it give a walkback. When you select avoid occlusions in a text morph with no dropped morph it disappears.

[Etoys] ScrollPane woes
by Karl 01 Nov '07

01 Nov '07

I made a little tutorial a few years ago which I showed how to make a SpaceInvader game. I now thought of updating that to the OLPC etoys and have a few questions about the presentation. The original tutorial was presented in a GeeMailMorph which is a scroll pane with a few added features. My first thought was to copy the text over to a scroll pane and update the screenshots. But I ran into some issues with the images dropped on the scroll pane wheSo there are some big issues with using a scroll pane. n I tried to change the text, they did not adjust to a larger font style. Text would just go behind the images etc. Also the images would not move accordingly to their dropped position if I changed paragraphs above, so all images in the the text below would be misaligned etc. Maybe the short solution is to use a BookMorph for my tutorial, but I think the ScrollPane issues should be fixed.

Re: [Etoys] Next milestone
by Bert Freudenberg 01 Nov '07

There was a recipe somewhere to work around that problem ... You might get lucky when asking on the OLPC developer list. It's a shame nobody at OLPC has time to care about emulation :( Did you request a B4 through the Developer Program? http://wiki.laptop.org/go/Developer_program#How_to_apply_for_an_XO It you mention the BotsInc project you might have a chance of getting one. Same for Hilaire with DrGeo. - Bert - On Oct 31, 2007, at 17:18 , stephane ducasse wrote: > In fact I took 623 but I cannot run it.

Hello Actually when you rotate an EllipseMorph instance with another object embeded, then this object -the second one- also rotate, but when you rotate a CircleMorph instance with another object embeded, the second one do not rotate solidarity. Regards

[Etoys] New version
by Bert Freudenberg 01 Nov '07

01 Nov '07

I made new RPMs, should be in next good Joyride build after 192: Etoys-64.xo etoys-2.2.1737-1.noarch.rpm etoys-2.2.1737-1.src.rpm * new translation framework, now .mo based * better support for drag and drop of sound files * new Sound Library tool * various fixes squeak-vm-3.9-12olpc3.i386.rpm squeak-vm-3.9-12olpc3.src.rpm * fix freeze in drag and drop * add analog input support * fix cursor keys New builds are announced on the olpc developer's list, and here: http://dev.laptop.org/~bert/joyride-pkgs.html Upgrading an XO to a joyride build should be as simple as typing olpc-update joyride-190 provided it is networked. This is much faster than the old download- and-flash-to-USB method (which still works) because it only downloads changes, not a full build. - Bert -
