Ah no sorry, it does work! I do have a question though: what if the orientation of the square, instead of always going back to 0, stays coherent with the motion?

I mean, for now, the plain colour does the trick, so we don’t see that the square goes back to 0° at every step it takes. But if the square contains content, you can see that trick and…

So to bother you all on that matter again. I was trying that expression again, but it doesn’t seem to work, although it did work perfectly a year ago. I just assume something has changed within After Effects.

The error message I get is only on the Anchor Point expression, and says “ReferenceError: a is not defined”. Do you know where that could come from?

Thank you Filip 🙏

Here is another demo of what I’m trying to achieve.

Here I chose a more obvious POV to see more clearly what is happening.

I did it here “by hand” cheating with the help of editing multiple compositions in a row, but my goal is to have all that happening on one composition, and have an expression that randomizes the result and the color palette…

Hello Hector, and thanks for your reply!

Yes, I modified a camera so the perspective is almost gone, and the volumes are seen flat when looked from the front. This is for me a way to create sort of a surprise, since the viewer will first assume he is looking at a flat graphics, which will, by moving, reveal its depth. Not sure if is what you meant…

Hello Creative Cows!

I’m trying to create an animation where a parenting bond would change depending on a random event.

To simplify the case, let’s say I have 6 cubes equally placed around a Null Object. Depending on whether the Null decide to turn either 90° on its X or Y axis, it will affect the cubes located on that same axis, like a Rubik’s…

Wow! Thanks a million Filip, it works like a charm!!

Thanks again and again!!

Hello, I’m trying to automate the animation attached.

What I try to achieve is:

—having a square, say 90×90 on a 1080×1080 canvas, where, every half second, the square randomly rotates smoothly by a 90° angle, clockwise or anticlockwise, from one of its corners.

—after each rotation, the square finds itself in a new position, that it should reta…

Splendid!!! Thanks a lot Dan, this works like magic!

Thanks Dan!! Do you know why the whole row gets triggered instead of just one single square, as shown in the video attached?

p = thisComp.layer("Target").position;
animateFrames = 15;
Hor = p.valueAtTime(0)[0] >= position[0];
Ver = p.valueAtTime(0)[1] >= position[1];
fCur = timeToFrames(time);
f = 1;
fSave = 0;
n = 0;
while (f <= fCur){
if (Ver){
if (p.valueAtTime(framesToTime(f))[1] < position[1] && p.valueAtTime(framesToTime(f))[0] < position[0]){
Hor = false;
Ver =…

Hi Dan, hi all, and tanks again for your help!

Based on the expression you sent, I tried to go further, and extend it to a 9×9 grid go squares, with the element named “Target” wiggling all over it, so not one axis anymore.

As you can see with the attachment, it does work somehow, but most of the times the whole row gets triggered, and, weirdly, only…

Thanks a lot Dan! It’s working like a charm

I forgot to mention:

—Target is randomly moving up and down, but with 100 pixels increments, not wiggling;

—all the squares are also 100 pixels high, and therefore, Target’s motion and the square-made scale match.

Hello!

I have an element called “Target” moving along the Y axis.

Along that same axis is a series of squares.

What I would like is, whenever the Target meets the height of one of those squares, the square spins 90° clockwise. When the Target moves away, the square should retain that value, and later, when they meet again, it will rotate 90° m…

Thank you Filip!

I figured it, and started to create a counter, but yeah… my computer overheated so I went for a simpler solution.

Thank you anyway, I really appreciate!

Hello everyone, I’m trying something I thought would be simple, but isn’t quite working.

Basically:

1. —I have a shape layer, and a null object on my scene. The null object’s position wiggles, and at times matches the position of the shape layer. I set up a hitbox to make this encounter as real as it can virtually be;
2. —so when when the null object hit…

Hello all,

I’m trying to write an expression that counts how many times a random event occurs. For instance, I have a solid with a wiggle expression on its rotation, and I would like a counter that sums up the number of times it passes by 0°. Any idea how it could work?

 

I know expressions don’t have memory, and I think that’s where I’m… Read more

Hi all!

I set up a wiggle expression on an object rotation. I want to set up the condition that whenever this object goes back to 0°, a random number gets generated. The expression I wrote is:

 

R= thisComp.layer(“triangle B”).transform.rotation;
if(R == 0){
Math.round(random(3));
}

 

When I apply it to the other object, I get… Read more
