    Hand on "arm" articulating

    in GSAP

    Posted

    I can get the hand to "stick" to the end of the arm when the animation starts, but the minute update Paths starts, the coordinate system gets wonky. I'm trying to use the motion path plugin relative path function, but just can't get it right. 

     

    Also would like to rotate the hand from 6 to 12 o clock while it's moving, but that's a dream right now.

     

    See the Pen YzbWZmo by robws (@robws) on CodePen

    Two-buttons invoke "Zoom" and then "Rotate" not working (locking)

     Given I'm using an SVG I load dynamically, I wasn't sure how to CodePen this, so hopefully it will be okay:

    I want the Start Animation button to zoom in on the SVG, then the Bad Monkey animation to animate the monkey's arm in the zoomed position.

     

    The zooming works right, but then pressing either button does nothing. If I press "Bad Monkey" first, it console.logs, but doesn't tie up the thread or whatever.

     

    The reason I tried to use a global timeline was to make sure the Bad Monkey animation occurred in the zoomed context (that is, the coordinate space was shared between the zoomed image and the desire to rotate an internal component).


    Any ideas?
