javascript - ScrollMagic and TweenMax Automatically executes -


hey im trying wrap head around this, been playing day. i'm trying accomplish have background image zoom in (and become transparent through opacity) when user scrolls down. i've got 1 half of desired effect working doesn't seem want work on user scroll, automatically executes.

it must simple im pretty new this.

here code i've written

    var tween = tweenmax.to('#regular', 0.5, {     scale: 2     });      // init controller     var controller = new scrollmagic.controller();       // create scene , trigger when visible scrollmagic     var scene = new scrollmagic.scene({     triggerelement: '#featured-image',     reverse: true,     offset: 700     })     .settween(tween)     .addto(controller)

http://codepen.io/anon/pen/ejwlyo

your basic problem settween method of scene not available & because missing include of animation.gsap.min.js important plugin in codepen when comes using tweenmax alongside scrollmagic.

so add this external javascript after scrollmagic include in pen , gold.
