I am building a flash piece in which I need an object to move across the stage from right to left and scale from 100% just off the right side of the stage, to 70% in the middle of the stage and then 100% again just off the left side of the stage. Giving the illusion that it is moving in a circular pattern around the viewer. My goal is to get the scaling to be relative to the MC’s x position on the stage. Moving it across the stage is the easy part, and I can scale the MC from 100% on the right to 0% on the left using an onEnterFrame function containing:

MC.\_xscale = MC.\_yscale = Math.round((MC.\_x/Stage.width)\*100);

but I can’t seem to figure the 100-70-100 deal out. I thought there might be a math function like sin, cos or tan that would really help out, but I can’t seem to find anything out there. Any Ideas?
