經過數小時的測試,我找到了答案。我看錯了。我需要將時間線進度與要轉到的框架聯系起來。在本例中,有 300 幀,因此乘以動畫中的幀數。
這是修改后的代碼:

<script>
// init scrollmagic
var controller = new ScrollMagic.Controller();
// Manage Animation
var animation = bodymovin.loadAnimation({
container: document.getElementById('lottie'), // Required
path: '/static/animations/scroll_animation.json', // Required
renderer: 'svg', // Required
loop: false, // Optional
autoplay: false, // Optional
name: "Welcome to Awesomeness",
});
// Setup Timeline
var tl = new TimelineMax();
tl.to({frame:0}, 1, {
frame: animation.totalFrames-1,
onUpdate:function(){
animation.goToAndStop((Math.round(this.progress() * 300)), true)
},
ease: Linear.easeNone
})
// Attach to scroll
var lottieScene = new ScrollMagic.Scene({
duration: '100%',
offset: 1
})
.setPin("#header-scroll")
.setTween(tl)
.addTo(controller);
</script>
