Animate an object around the perimeter of a rectangle

[cgele]

Can anyone tell me how to animate an object around the perimeter of a rectangle, using a programmed value that contains the distance of the rectangle perimeter?  I can animate the object in a straight line using the full range of the value, but I need to break the value into pieces to represent all sides of the rectangle.

Thanks,

Chris

I made an example. Hope this helps you.

I assume length:width = 3:2.  Divide the perimeter into 100 pieces, 40 for width, 60 for length. Use a counter to count the pulse. The counter resets at 100. Then, use an expression to calculate the X and Y.
