I’m playing around with the Farseer Physics Engine these days and needed to draw the “collision boundaries”. These are called Geom (Geometries) in Farseer language and these are made up by Vertices.
Cameron Albert have already made code to do this and I have already used it in my Farseer Physics Simple Samples so that were an easy one.

Then I ran into some problems/confusion with the “position” of elements. Basically it was due to that Farseer’s position is at the center of an element, whereas Silverlight’s version of position is at the top left corner. This is actually not that confusing as it is written here, but it can quickly become pretty confusing, at least I think :)

The 16. Dec. 2009 I did a talk about game development in Silverlight 3 in Copenhagen, Denmark. Thanks to all the people showing up, hope you had some good hours too :)

One thing that I found especially cool were that one of the attendees was a 10-12 year old boy (he brought his dad of course :) ). He already did a game in Game Maker he told me, very cool!
To the dad of this boy: I told you about some “kids programming language” that I couldn’t remember the name of. I goggled it this morning and found it: http://phrogram.com/kpl.aspx it might be a good start into the world of programming.
The other thing I told you about were GarageGames, take a look at this it comes with a WYSIWYG-like IDE, but it also have it’s own scripting language (similar to javascript) that you can code in. For more info take a look at it here: http://www.torquepowered.com/products/torque-2d

Slides and demos
I have put up the 4 demos, 1 Physics Helper demo for Blend and the powerpoint file, all in a zip file which can be downloaded from here: http://laumania.net/downloads/GameDevelopmentInSilverlight.zip

Again I would like to thank people who came and hope you found my talk interesting and learned something.

- Enjoy and marry xmas :)

The samples have been upgraded to Silverlight 3.0, which means that the source code is now targeted at the Silverlight 3.0 Tools for VS2008. Besides that the Farseer Physics Engine code have been upgraded to version 2.1.1.

Go and get the new release from Codeplex.com

- Enjoy!
