I'm making a game for my final project in programming, and I need a little help with curved lines. I'm making 3 Card Monty (http://www.isy.vcu.edu/~cstewart/info350/FinalProject.html) and need a way to move two of the cards around at the same time. I know how to actually do the code of animating the cards, but I don't know how to come up with the equation to do it with an arc. Can anybody help me here?
