I've been playing with creating an asteroids type game and I have to say I'm pretty impressed with Silverlight Alpha!
If you want to take a peek at the work in progress, you can
go here. Also a
blog post on the subject. It's not a complete game but I think I've proofed out input, frame rate, graphics... I hope to complete the game soon and post up the code as a sample.
Anyway, I wanted to give some feedback on the Alpha for whoever is listening on the dev team
I needed to implement my own (crappy) collision detection. I really expected with all of the vector capabilities that HitTest functionality would be in Silverlight but it isn't (yet anyway).
There isn't a "real timer" class in Silverlight yet, so you need to use an Animation Timer as a workaround
The KeyDown event doesn't appear to support arrow keys. Hopefully this will be fixed before release.
I'm not sure if this is something I'm doing but my MediaElement only plays once
