Hi George,
This might be a good one for a FAQ.

I am developing a turn based strategy game with tanks similar to Scorched Earth.
I need to be able to get distance of the opponant in a pop-up panel and controll the tilt and pan of the tank barrel as well as the power of the artillery shell, thru the panel similar to the panel in your Fogger article from AUM 25.
It would be good if the controll could also be given for the mouse.

Perhaps also, finding distance from mouse_ent.
Cheers.
