Hi there, I had a chance to test my svg on IE9 today and was delighted to discover that it worked just fine - no, it ran smoother than on anything else I have tried thus far. I got more than 500 rectangles zipping about with no hangs or pauses. Better performance even than Chrome, which is otherwise very smooth.

I am just getting my hands dirty at the moment, although I have plans to make this demo into a little duck-shoot game, just as a proof of concept, which may explain some of the design decisions. I also have a <use> in there, which isn't strictly necessary. And I used jslint with "assume a browser", which enforces some rather odd coding conventions. I will be asking more questions soon about best practice ecmascript in svg. :) > 5.

I used to be really into SMIL back in version 1.0 days, and even made a SMIL interpreter / renderer in ActionScript 2.0 at one point. I added my own custom extensions to handle transitions, but otherwise it was pretty clean SMIL. I haven't really looked at SMIL since, but I am glad it still has a bit of a fan club, even if it is still more occult than it ought to be. But in SMIL, everything is 'on rails' right? Or would it be possible to make a game like (say) asteroids using SMIL? (Instead of ecmascript, I mean). I thought the whole point of SMIL was that everything is synchronised, whereas games tend to rely on 'autonomous' life cycles. For example, in my demo, each 'clone' has its own horizontal speed, randomly decided. I wouldn't know how to do that with SMIL. > Some of these points can be argued half a dozen ways apiece, and they are > presented more as possibilities to consider than as beliefs or truths. I especially appreciate this point. :) ------------------------------------ ----- To unsubscribe send a message to: svg-developers-unsubscr...@yahoogroups.com -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" ----Yahoo!
