Hi and thanks for the reply. I am now using the .NET package rather than the XNA one - off to a good start :). Now, about the loop.....
a) I wasn't sure what method to call for the farseer engine to "recalc" positions, speeds etc of bodies; and if I did
b) I assume Farseer needs to know exactly how long it has been since the last update was run. If I were to take a very simple approach and use a timer to fire this "Update" method every 5ms then this would be ok
but what happens if for some reason the computer were busy doing someing and it couldn't fire the update until 15ms or 100ms had elapsed. Does Farseer keep track of the time between updates? I noticed
the use of a Gametime object under XNA - is this still used under the .NET model?
Again, thanks for any help and Merry Xmas.
