Can't quite wrap my head around loopOut() ???

[Guest]

So at first I was confused and not sure if my next loop started immediatly upon the same frame as my last keyframe, or on the next frame after it?

I've set up some simple expeiments and I'm pretty sure it starts on the same frame as the last one, overwriting the last keyframe with the first.

So, I have a box whose opacity is

100% on frame 0

0% on frame 10

then on frames 20, 30, 40, etc it is 100%, and it fades down, and never actually gets to 0%, except for on frame 10.  Seems a little weird to me, but okay.

But I feel like there are anomolies.  In particular, I have a circular mask and I am animating the mask's expansion so my object is hidden on frame 0, iris's on by frame 60, and then holds till frame 100, at which point I want it too repeat.

So I have mask expansion

-222 on frame 0

0 on frame 60

0 on frame 100

Now when I go to frame 200 expansion is at 0, not -222 like the box experiment lead me to assume.  So I set frame 100 to --222, and frame 60 to be a hold keyframe, and go to frame 200, and it is still 0, even though both frame 0 and 100 are set to -222.

I am confused????

To get loopOut() to cycle the way you expect, you just need to make sure you set your keyframes up so that the last keyframe has the same value as the first. So in your last example, try moving your second 0 keyframe to frame 99 and setting a keyframe for -222 at frame 100.
