Mouse Picking Q [SOLVED]

I am currently working on a game which is going to have numerous actors moving around a space. I intend to have classes with statistic variables and I want to be able to display those statistics when the actor is moused over, or something similar. This whole system is still in the conceptual phase.

In the manual, on the page for the chessboard sample, it mentions that there is a faster method to accomplish the mouse picking using the Plane class. What is that method? Will it function for a system where you have actors moving along a flat surface, but are not limited to specific points or squares?

Thanks for the link, Pro-rsoft. That method most likely won’t be the best option for mouse picking actors, but it will be very useful for giving the actors location based instructions via the mouse.
