Thanks plamen,

well now that I reviewed it, the default FPS is actually 30 making 30/1000=0.03. Lol (updated the post now)

Yeah, I get it I wrote everything on a paper and also made a lot of traces in the code you wrote to see different situations and results Good job Jayc. I really like your posts in FGL too . Keep going !

If your frameTime is 1 then that would mean that it took 1 sec for the next frame to be called again (an incredible frame rate drop of 1 fps). So you get 33.33 frameSpd and have to adjust all speeds 33.33x faster to catch up everything. But the next line (14) limits that amount of catching up to 2.5, so any frameTime slower than 0.075 sec (75ms) would no longer be tolerable.

It’s set to 0.030 because the swf is set to 33fps by default.
33/1000 = 0.030 (well its 0.033 actually)

So normally frameSpd would be 1 when runtime fps is the same with the default fps.

I don’t get it. What are you doing on line 13?
frameSpd = frameTime / 0.030;

Let’s say frameTime is 1 ( 1 sec ). If you divide it by 0.03 you will get 30 sec? Right? Is that what it should be ?

[...] This is because our frame controller must be able to tolerate slight FPS reductions based on time (detailed on this post). So when the animation is played from the timeline during design time it would appear to be quite [...]
