Help! Syntax error message

[Walter Soyka]

Allie, it looks like there are a few mistakes or typos in here. Can you briefly describe what you’re looking for this to accomplish and then I can make some suggestions?

Hi Walter, thanks for reaching out. I was following along to a video tutorial (link below) I have triple checked the spelling used and because I’m a novice I’m blindly following instructions! Anyway, it’s a recursive animation, expect instead of using a rectangle I’ve used an ellipse. Many thanks for your help.

Did you convert your Ellipse path from a parametric path to a Bezier path?

Also, you’re redefining point1 over and over; I think you want to change those to the other 3 points, like this:

indexProperty = thisProperty.propertyGroup(1).propertyIndex;
mask1 = content(indexProperty-1).path;
point1 = linear(time, 0, 2, mask1.points()[0], mask1.points()[1]);
point2 = linear(time, 0, 2, mask1.points()[1], mask1.points()[2]);
point3 = linear(time, 0, 2, mask1.points()[2], mask1.points()[3]);
point4 = linear(time, 0, 2, mask1.points()[3], mask1.points()[0]);
createPath(points = [point1, point2, point3, point4], inTangents = mask1.inTangents(), outTangents = mask1.outTangents(), isClosed = true);

Hi Walter,

Thanks, I pasted your edited code and the following error came up on the point1 line

TypeError – cannot read property “points” of undefined….

[Walter Soyka]

Can you post your AEP so I can see what you’ve got set up?

[allie litherland]

Hmm, it appears this forum doesn’t support aep files…I could screen shot?

[Blaise Douros]

I brought this up recently; the Cow staff replied that are working on getting the .aep file type added. For now, you can upload an .aep within a .zip file, and it’ll work fine that way.

Thanks Blaise,

This works in your AEP:

indexProperty = thisProperty.propertyGroup(1).propertyIndex;
mask1 = content("Ellipse 1").content(indexProperty-1).path;
point1 = linear(time, 0, 2, mask1.points()[0], mask1.points()[1]);
point2 = linear(time, 0, 2, mask1.points()[1], mask1.points()[2]);
point3 = linear(time, 0, 2, mask1.points()[2], mask1.points()[3]);
point4 = linear(time, 0, 2, mask1.points()[3], mask1.points()[0]);
createPath(points = [point1, point2, point3, point4], inTangents = mask1.inTangents(), outTangents = mask1.outTangents(), isClosed = true);

But the tangents will probably not work the way you expect. How do you want this animation to work?

[allie litherland]

Thanks Walter, it does animate but you’re right not how I was picturing it!

I wanted to create similar to the youtube video (https://www.youtube.com/watch?v=SSdyo5BbRvM&t=2s) rather instead of squares they are circles. Something I thought would be a simple task I wanted this to expand for 5 seconds and collapse for 5 seconds to mimic a breathing technique.
