It's a friggin' Flash-applet, so there's nothing to install. Just click the link and start making a level. Sheesh.
Following TANSTAAFL's buglist (scroll down about two entries), it appears that Flash MX 2004's tooltip classes have a bug. Well, not really a bug, but just something that Flash can't do. In a regular Windows app if you hover your mouse over a button near the edge of your app's window, the tooltip will happily display itself off the edge of the Window. You can't do that in a Flash applet, though. All drawing in a Flash applet has to occur in the space granted to it. The tooltip object in Flash is smart enough to scoot itself around horizontally if you're near the left or right edge of your applet, but it always stays below the mouse cursor. Hence, if you've got a button near the bottom of your applet the tooltip will be clipped off.
The obvious solution was to make the applet a bit taller so the entire tooltip could display. When I did that, however, I found myself with enough space for a little status-help display. So I dumped the tooltips entirely and just made everything display help there.
I was also able to prune another 6k out of the applet. The whole level builder now clocks in at about 33k. Pretty good considering that the first one I uploaded was 79k. And I'm not just being obsessive about size. Small applets are good because they load faster on slow connections and save you space on your monthly ISP bandwidth limit.
Ghostwire just updated their lightweight PHP-Flash communication object for PHP 5, so I've now got no excuse for not starting on the server stuff.
I'm taking a break from Asimov for a short time. I'm currently reading Mountain Man by Vardis Fisher. Good read. It's pretty violent stuff, but I don't think you could write a book about the mountain men without violence unless it was a romance novel.
