AllanR excellent... I thought that the width/height of the sprite would just change the box not the text like Sine does for size... cool!
still though, triple nested events for a simple movement. This should really be a Behavior if I ever saw a need!
No I only wanted half of the Sine's cycle. Normally a Sine starts at zero and goes to 100 then goes down to -100 and back to 0 for a whole cycle. I only wanted the 0-100-0 bit. you got it right in your example.
