x amount of position move on layer marker
I have a null layer with an X position move and another master null with a some boxes attached.
Trying to have this master null move X positions (1734px to be exact) every time theres a layer marker on the master null.I tried using below expression but even if I add more “if”s, I only got it to move twice.
Help?
position;
if (marker.numKeys > 0 && time >= marker.key(1).time){
thisComp.layer("Ctrl_Pos").transform.position.valueAtTime(time-(marker.key(1).time))+position;
}

Try this:
m = marker;
n = 0;
if (m.numKeys > 0){
n = m.nearestKey(time).index;
if (time < m.key(n).time) n--;
}
value + [n*1734,0]

What if don’t want it to jump but have it slide over?

More like this, I guess:
m = marker;
moveTime = .5;
moveAmt = 1734;
n = 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;
x = (n-1)*moveAmt + linear(t,0,moveTime,0,moveAmt);
value + [x,0]
}else
value
