Offset range expression

[Adam Zygadlo]

Okay, I had a little play this morning using other posts to understand some codes.
I am very close to to the desire effect but it’s wiggling around… I just want it to lock/clamp in position.

I know it’s the ‘slide = random(maxX,minX);’ line of code isn’t right but not sure how to write it up.

Can anyone help?

Cheers,
+Z

maxX = 40;
minX = -40;
offset = -257; // Resets the

slide = random(maxX,minX);
x = (slide-offset);

[x,0]

Okay, I’ve solved the wiggling issue and adjusted the code.

Cheers,
+Z

maxX = 50; // Setup Max range
minX = -50; // Setup MIn range
offset = -359; // This is to cancel out the default position of the Anchor Point
posterizeTime(1); // This stops the wiggling of the layer.

slide = random(maxX,minX);
x = (slide-offset);

[x,0]

Between the offset and slide lines add this:
seedRandom(index,true)

It takes a different random number for each layer, but doesnt take a new random number at every frame.

If the project only needed one frame of the pile of paper, then my code would be ideal; however it changes position while scrubbing through the timeline. Nice effect but not desired! Oops!

After looking around, I tweaked the code around and told it to hold on a couple of frames but your suggested code is cleaner. :^)

Thank you Xavier for that!

period = 1000; // frames
posterizeTime(1/(period*thisComp.frameDuration));
