Silverlight 3 and Blend 3 introduce the concept of Behaviors, which make it easy to add common functionality using drag/drop inside Blend.

I’ve been working on creating a set of Behaviors for the Physics Helper Library, and have made good progress. Using these behaviors, you can very quickly put together physics-based games and simulations with little or no code. (Ok, I don’t really believe in the no-code scenario … but you can do some pretty neat stuff without code). Another new feature in the library is the ability to automatically determine the outline (collision boundary) of raster images (such as a PNG).

I’ll be releasing this updated library soon on Codeplex, but here is a screencast I put together to show the Behaviors in action:
