    Hi all.

    Are there any known bugs in AE CS4 related to the loopIn expression?

    This is why I ask:

    I’m tracking a person that enters the screen at the left side and keeps walking until disappearing at the right side. My plan is to use a null object as the tracking target so later I can add a cartoon character that follows this person, as if they were together before they appear on screen and later as if they left also together.

    I used loopOut(“continue”) to get the tracking out of the screen and it worked just perfect. When doing the same for the moment when this person enters the screen, I used loopIn(“continue”)… this is where all comes to an end =(

    As a tutorial said, I used the following expression for the entire animation:

    Layer >> Track point >> Feature Center >> if(time<2) loopIn("continue") else loopOut("continue")

    Where time<2 indicates that I need loopIn to work the first 2 seconds, leaving the job later to loopOut.

    BUT after several approaches, I just can't seem to get loopIn("continue") do it's job.

    What I am missing???

    Please help!!

    Thanks!

    For that to work, I think your first keyframe would have to be at 2 seconds. Is that the case?

    Dan, you’re my hero. I wasn’t looking at the small picture and missed that particular detail.

    My keyframes started a little bit earlier than the 2 seconds mark. I thought the “if” conditional would work no matter where the keyframes started but this is not the case.

    Thank you very much!!
