Expression with delay

Sep 25, 2012 2:42 AM

Hi,

 

I'm a nooby when it comes to expression, so can anyone please help me with how I can create a certain expression?

 

I think it's quite simple. I've got 2 layers. One layer has an animation (leader) and the other one needs to follow. Only with a delay of 1 frame. The animations happens on "position", "scale" and "rotation".

 

Thanks you very much in advance!

 

Best regards,

 

John

    These should work:

     

     

    thisComp.layer("leader").transform.position.valueAtTime(time-thisComp. frameDuration)

     

     

    thisComp.layer("leader").transform.scale.valueAtTime(time-thisComp.fra meDuration)

     

     

    thisComp.layer("leader").transform.rotation.valueAtTime(time-thisComp. frameDuration)

    Hi Dan!

     

    this really helps! Thank you so much.

     

    Only one more question, because how can I change the number of frames it delays on this expression?

     

    Best regards,

     

    John

    This should work:

     

    delayFrames = 3;

    delay = framesToTime(delayFrames);

    thisComp.layer("leader").transform.position.valueAtTime(time-delay)

    These kinds of delays can also be done easily with mamoworld's iExpressions for After Effects.

    This requires no code writing at all:
