Using Follow The Leader expression with multiple shapes within a single shape layer
I’m trying to use the “follow the leader” expression to animate multiple paths/shapes within a single shape layer. I’m not sure how to modify the expression to reference the individual “contents” of the shape layer or if this is even possible.
Trying to clarify–rather than using multiple layers with the expression I want to use multiple shapes within a single shape layer. The reason being is I have some vector art that I am converting to shapes in after effects and it converts all the shapes within a single shape layer and I want to be able to get the transform properties for each path/shape/content.
Am I making sense? Thanks for the help!
delay = 5; //number of frames to delayd = delay*thisComp.frameDuration*(index - 1);
thisComp.layer(1).position.valueAtTime(time - d) -

It’s a little trickier for shapes. It helps to use the mysterious propertyGroup() function to navigate the hierarchy of properties. It should look something like this:
delay = 5; //number of frames to delay
leaderProp = thisComp.layer(“Shape Layer 1”).content(“Ellipse 5”).transform.scale;
leaderIdx = leaderProp.propertyGroup(2).propertyIndex
myIdx = thisProperty.propertyGroup(2).propertyIndex;
deltaIdx = Math.abs(myIdx-leaderIdx);
d = delay*thisComp.frameDuration*deltaIdx;
leaderProp.valueAtTime(time – d);Dan

Hello, it works fine but is it possible to specify one fixed axis of the position (in order to not follow the x Leader ‘s position)?
Thank you -
I haven’t tested this, but try changing the last line to this:
p = leaderProp.valueAtTime(time – d);
[value[0],p[1]]Dan

It works great
Thank you 🙂
