I have a real simple animation when you scroll the page using ScrollMagic I want to know how do you play the animation only once after you have scrolled the scene into view of the trigger.

 

var controller = new ScrollMagic.Controller();

var tween_1 = TweenMax.to('#obj_1', 0.5, {
    left: '0%', delay: .1
});

var containerScene = new ScrollMagic.Scene({
    triggerElement: '#scene_1',
    offset: -100
})
.setTween(tween_1)
.addIndicators()
.addTo(controller);

If I understand correctly, you want the Tween (once triggered) to remain in the tweened position and not reverse back to it's pre-triggered state when scrolling back ... is that right? If so, that's as simple as setting the reverse value to false on the scene.
