How do i get the height of a mask ? I've tried:
Both on shape, and movieclip, but all of them returns undefined propierty 'height'
As far as I'm aware, you don't. Mask shapes are generated when you publish, and are only intended for internal use by the render engine.
What problem are you attempting to solve by getting the mask height?
I was trying to auto position elements on stage. I have a scrolling clip and im animating it using gsap. Just wanted to have universal line to position the clip end Y or X based of size of clip and mask. When clip reaches the end point, next animation is trigered.
