Y position controled by marks
Hi. I need to make final credits animation project, but they have to be showed step by step. What basically I need is an expression which read several marks ( a variable quantity of marks) in a layer named “control” and moves a 3D null in the “y” position (100 pixels up) every time the indicator pass over a mark of this layer. The movement has to be an easy movement. In other words, the expression has to move the null 100 pixels up (“y” position) with the first layer mark and when it passes over the second mark has to move the null another 100 pixels more in the same direction and the same with the rest of the marks, always with an easy movement. Thank you for your help in advance.

Something like this maybe:
m = thisComp.layer("control").marker;
moveDur = .25;
y = 0;
if (m.numKeys > 0){
n = m.nearestKey(time).index;
if (time < m.key(n).time) n--;
if (n > 0){
t = time - m.key(n).time;
y = ease(t,0,moveDur,(n-1)*100,n*100);
}
}
value - [0,y];

Hi, Dan. Amazing response as always.
It works awesome!! is there some way to make the movements even smoother? I really appreciate your help. Big thanks! -
If it is possible, a little easy in and easy out or bounce effect between movements will be great. Thank you again.
