Hi all,

I'm looking for a way to do this: Show text where the letters are positioned randomly across the screen. Then gradually move the letters towards their correct position, to show the original, readable text... any suggestions? Thanks!

Tim

IIR: next position := current position * 0.95 + 0.05 * target position (will never reach target exactly)

FIR: current position := start position * (1-t) + t * target position (with t in 0 .. 1)

You need one of the above for each coordinate of each letter, so I suggest storing the information in arrays (or data structures) and looping through them.
