I want to thank Eric Dodson, Jeff Patterson, Michael Bashista, Mark Andrade, Glenn Picher, Dan Gorman, and any others who responded to my inquiry regarding animating a sprite in a circle using Lingo. They came up with some very interesting and useful code, which I'm including here.
Radians are different than degrees.
Remember, I just used the locH and locV, not the center point for the sprite, you'll need to take that into consideration. The following script will revolve a sprite in the path of a hypotrochoid, which is a sort of cursive clover shape. If somebody like this, please send a thank you note off the list.
