No ... don't reduce your frame rate ... that will not lessen the time it

takes for the processor to deal with key frames and tweening ... which is

the reason your animation is going slower than the intended. Increase it if

anything.


If it still goes too slow at 20fps, then start looking for blank frames to

remove. And remove a lot of them ...


It seems that Flash does not "think ahead" and begin to make calculations

until it arrives at a key frame, or else this wouldn't work, but it does.

An analogy would be this: You have to run ten blocks and stop at every

corner to read a page of directions which explain which way to turn. Since

it is always going to take you the same amount of time to read that page,

the only way you can go those ten blocks quicker would be to:


1. Run faster (increase your frame rate)

2. Reduce the distance between corners (eliminate blank frames)

3. Use easier to understand directions (reduce the complexity of tweened

shapes/redraw less of the screen)


The frame rate only applies to how fast you are running, not how fast of a

reader you are.
