Picking and Bounding Boxes

Got the next essential small step of the project in today, picking, that is selecting an object that exists within a 3D world from a mouse click in the 2D world. Found some really good resources for this including the Hazy Mind site again and a new one I discovered by accident by Charles Humphrey. I had a little trouble at first with working out how to calculate a bounding box, but yet again the XNA community came to my rescue. Thanks to Andy and his blog I now have a custom content pipeline that generates a bounding box for my mesh automatically.

Now that you can select a unit on the map the next step will be to add the ability to add properties and gulp custom scripts!
