Re: [etoys-dev] Stencils in Etoys

Subbu, Thanks this is a lot of fun and useful. So I tried to use it for fractions (although I really like your art work project at Ofset <http://community.ofset.org/index.php/Grab_area_button>better, but I am thinking about fractions lately) I used the "do menu item | stencil a sketch" scripting tile in a "Mouse Down" script. The rectangle then moves forward by its width. So with a series of successive clicks you can make a fraction. It get's my vote for inclusion in the next release. Thanks, Stephen On Fri, Jul 22, 2011 at 10:02 PM, K. K.

Re: [etoys-dev] [squeakland] File error on open and sound reverb problem again

(Including etoys-dev list again) It should be possible to batch change like that. You probably would have to do some Smalltalk behind the Etoys to accomplish it though.

Step by Step debugging and Etoys
by Steve Thomas 17 Nov '11

17 Nov '11

So the argument I have heard as to why Etoys does not have a single Step Debugging like Scratch seem to go along the lines of "If we step one script, the whole world waits". I have two responses to this: 1. So? 2. Should we let the search for an elegant solution (that a few developers will see and appreciate) prevent us from providing a tool that can positively impact many children? *So on "So?":* So what if the whole world stops? Yes, I know and can think of some cases where this will impact the ability to debug certain issues, but my guess is these are a small minority of cases and I do not see any negative consequences (other than the single step debugging is not ideal in these few cases, but it would still be better than no single step debugger). *A solution versus an elegant solution:* Another way to solve this problem (which I will assume others have thought of, so I am probably missing something) is to do something similar to what Bert did in his Squeakland presentation where you "roll your own tiles" and place them in special holders (like "do together" or "do one at a time"). When you click on "debug" or some other similar script icon, a new "special script" is instantiated that has a copy of each tile, but it operates one "step" at a time, doing the step during its cycle. This would allow the whole world to continue to run and provide single step execution of tiles (or copies of those tiles inside a special scriptor, that runs one tile at a time.). The one addition I would make to the approach above is along the line's of the one in Scott's recent talk<http://tinlizzie.org/~bert/scott-2011-11-08-q35.mp4>. Where you add an icon (the exclamation point in a yellow circle) to allow the user to execute one tile at a time in any order/timing they want. Another possibility would be to allow the user to "toggle" the visibility of a yellow exclamation point for each tile, this would be to allow kids to display the "fire tile" icon and just click through one at a time, which would also allow single step debugging (versus run at a slow pace, and frankly I prefer kids click each time, as it forces them to slow down and think. When doing "Test" tiles not sure if you should highlight "Yes" or "No" or just skip to the first tile in that section. I lean toward the former. Stephen

Event Theatre issue

Do you mean the button, PaintBoxColorPicker, or PaintBoxMorph>>eyedropper:action:cursor:evt: ? I have still to digest SketchEditorMorph>>mouseMove: but it mentions "eventRecorders", although I admit to finding the code a little tortuous so maybe there is a simpler solution. Please don't use the bug tracker for discussions (*). That's what the mailing list is for :) Basically, any direct reference to Sensor circumvents the Morphic event processing. It is from the old MVC days. The only legal usage is in HandMorph, which needs to read events from Sensor. So there are a couple of offenders: SystemNavigation default browseAllSelect: [:m | (m hasLiteralThorough: #Sensor) and: [m methodClass inheritsFrom: Morph] ] PaintBoxMorph>>eyedropper:action:cursor:evt: is one of them, as is PasteUpMorph>>chooseClickTarget (which is used to select players). - Bert - (*) http://producingoss.com/en/bug-tracker.html
