If I remember correctly, you just need to add a new keyframe one frame before the second keyframe that AE creates when you turn on time remapping. Then change the value of the last keyframe to 0. Something like that.

I may have misunderstood. My previous example will vary the random values. If what you want is one set of random values that repeats forever, this should do it. You can, of course, connect A, B, C, and D to sliders if you want.

A = 3;
B = 7;
C = 5;
D = 11;

f = Math.round(time/thisComp.frameDuration);
seedRandom(index,true);
period1 = Math.round(random(A,B));
period2 = Math.round(random(C,D));
t = period1 + period2 + 2
d = f%t;
if (d < period1){ 0 }else if (d < period1 + 1){ random(100) }else if (d < period1 + period2 + 1){ 100 }else{ random(100) } Dan

Give this a try:

A = 3;
B = 7;
C = 5;
D = 11;

f = Math.round(time/thisComp.frameDuration);
t = 0;
j = 0;
while (f >= t){
j++;
seedRandom(j,true);
period1 = Math.round(random(A,B));
period2 = Math.round(random(C,D));
t += period2 + period1 + 2
}
if (f < t - (period2 + 2)){ 0 }else if (f < t - (period2 + 1)){ random(100) }else if (f < t - 1){ 100 }else{ random(100) } Dan

In this setup, Vx0 becomes (in pixels) how far the object will move in the x direction. The first parameter of Math.pow() determines how quickly it will get there, with 1.0001 being very slow and 10.0 being very fast (I think).

Try changing the last line to this:

[position[0] + Vx0*(-Math.pow(2,-time) +1), floor – y]

You may have to crank up the initial x velocity.

Mike,

I doesn’t look like the expression has any friction or damping for motion in the x direction – as you’ve discover it just keeps moving at a constant velocity. Let me give it some thought.
