move to layer position

[Dan Ebberts]

Yes, you could do that, but what controls the timing (how does the expression know when it’s time to move to the next layer)?

Oh hi again Mr Dan. im glad hear that you said that posible to do. timing can be control via slider or variable. let say, 5 sec and move on. if you could write some, i most appreciate it.

Thanks Dan for replying.

Play around with this. It should move layer 1 around the comp in 5-second increments. First to layer 2, then to layer 3, etc.


holdDur = 4;
moveDur = 1;
startIdx = 2; // start with layer 2

segDur = holdDur + moveDur;
curSeg = Math.floor((time-inPoint)/segDur);
t = (time-inPoint) % segDur;
if (curSeg == 0){
L1 = null;
L2 = thisComp.layer(Math.min(thisComp.numLayers,curSeg+startIdx));
}else{
L1 = thisComp.layer(Math.min(thisComp.numLayers,curSeg+startIdx-1));
L2 = thisComp.layer(Math.min(thisComp.numLayers,L1.index+1));
}
if (t > moveDur){
L2.transform.position;
}else{
t1 = curSeg*segDur;
t2 = t1 + moveDur;
if (L1 == null)
p1 = value
else
p1 = L1.transform.position.valueAtTime(t1);
p2 = L2.transform.position,valueAtTime(t2);
ease(time,t1,t2,p1,p2)
}

Omg. Im speechless. this code work just like what im imagine. thank you Mr Dan. i will work around with this code.

again, THANK YOU MR DAN!!!!

Hi Dan,

I realise this thread is nearly a year old now–but I think it relates to what I’m looking for. I’m looking to do the same thing as the OP: move one layer’s position to another layer’s (possibly in another comp) position, according to its index; but I’d like to able to control / trigger it with keyframes (a slider on a null, perhaps) rather than have it automated. Additionally, I’d like to be able to apply this to several layers, but–let’s say they’re all controlled by a slider on a null layer (i.e., one controller for several layers)–offset the timing they each start animating.

Hope that makes sense.

Thank you in advance.

Ben
