[进入窗口时使用ScrollMagic自动播放SVG

Question

我有这个SVG，它使用ScrollMagic进行滚动动画（svg绘图），效果很好，但是我要寻找的是svg进入窗口时会自动开始自动播放并完全进行动画处理，并且不会在滚动时缓慢地进行动画处理。

有没有办法做到这一点？

	function pathPrepare ($el) {
		var lineLength = $el[0].getTotalLength();
		$el.css("stroke-dasharray", lineLength);
		$el.css("stroke-dashoffset", lineLength);
	}

	var $word = $("path#word");
	var $dot = $("path#dot");

	// prepare SVG
	pathPrepare($word);
	pathPrepare($dot);

	// init controller
	var controller = new ScrollMagic.Controller();

	// build tween
	var tween = new TimelineMax()
		.add(TweenMax.to($word, 0.9, {strokeDashoffset: 0, ease:Linear.easeNone})) // draw word for 0.9
		.add(TweenMax.to($dot, 0.1, {strokeDashoffset: 0, ease:Linear.easeNone}))  // draw dot for 0.1
		.add(TweenMax.to("path", 1, {stroke: "#33629c", ease:Linear.easeNone}), 0);			// change color during the whole thing

	// build scene
	var scene = new ScrollMagic.Scene({triggerElement: "#trigger1", duration: 200, tweenChanges: true})
					.setTween(tween)
					.addTo(controller);

* {

}

#trigger1 {

.spacer {

尝试将ScrollMagic.Scene持续时间中的持续时间设置为零-此处演示：https://codepen.io/Alexander9111/pen/XWJozXZ
