We are compiling the new Anaara web site (soon to be live) for flash 10 but one of our client projects is being compiled to flash 9. I have a demo in the morning for the client but had updated to flash player 10 when running our web site project…checking the demo I found that one of the games (its a mini universe filled with various games) was hosed. Luckily I found this post by Ryan Stewart on switching between the player versions. Pay attention to the comments…they are even more useful than the original post.
On another note, I had heard that one of the reasons why they couldn’t port the Flash player to the iPhone was that as of version 9, the performance of flash player on MacOSX was horrendous compared to on Windows. Funny, I never noticed (I switched from PC to Mac on ver. 9). I also heard that Adobe had been working on improving this issue, as a first step towards getting Flash on the iPhone. Guess those improvements aren’t part of the FP10 release. Too bad… (also still waiting for C library support in Flash…what version will that be available?). Its also a little sad that the hardware acceleration features of FP10 are Windows specific as well. Maybe the Flash Player dev team at Adobe needs to be forced into switching to developing on MacOSX…but at least it seems they are trying to improve.
