[Sugar-devel] progress and issues w/ adding_up
I have adding_up kind of working w/ the new html layout, but it doesn't actually add up to the correct sum :( Problem #1 I kept getting an infinite loop in this section in the distance2() call I have to admit I don't exactly understand what distance2 is doing http://git.sugarlabs.org/projects/karma/repos/mainline/blobs/multicanvas/examples/adding_up_to_10/js/lesson.js#line142 for ( var j=0; jhttp://git.sugarlabs.org/projects/karma/repos/mainline/trees/multicanvas -- Bryan W.

I have fixed the bug
the problem was here:
http://git.sugarlabs.org/projects/karma/repos/mainline/blobs/122ecd00112941ccde74932aef01c93d1b5c7cdb/examples/adding_up_to_10/js/lesson.js#line179
the problem was that "this" inside the callback function (for the click
listener) is not the same "this" of the "each" function
I changed this["id"] to item.id
+ changed language to "spanish" :) (btw. could u get some decent english
audio for "correct"/"incorrect" ?)
+ I have done some other changes (stylistic)
