Animating with the new KineticJS

[Michael71 59 Likes (Contributor)]

Hello,

 

I was working with the new KineticJS version and the 2D Physics from GSAP.

 

Although there is no visible error, I can't seem to animate an element the way I used to, with TimelineMax/Lite and "onUpdate:stage.draw", "onUpdateScope:stage"

Anyone has any ideas or has faced similar problem?

 

I have set up a codepen here: http://cdpn.io/lzkbu

 

Thanks in advance!

Hi Michael,

 

I see the problem. I don't know how familiar you are with KineticJS, but Kinetic objects don't have x and y properties. They have setX(), setY(), getX() and getY() methods.

 

The physics2D plugin assumes you mean to change the x/y properties of the target object (which Kinetic objects don't have).

 

The plugin is very flexible and allows you to specify the yProp and xProp (see docs)

 

 

 

TweenMax.to(dot,2,{physics2D:{

      velocity:getRandom(80, 380), 

      angle:-10, 

      gravity:400,

     xProp:"setX",

     yProp:"setY"

    }

    }));

 

I modified your code and forked your pen
