在Aframe中使摄像机在路径上设置动画,以保持对主题的关注,可以通过以下步骤实现:
示例代码如下所示:

<a-curve-point position="0 2 5"></a-curve-point>
<a-curve-point position="5 2 -10"></a-curve-point>
</a-curve>
</a-entity>
<a-box position="-5 2 -10"></a-box>
<a-box position="0 2 5"></a-box>
<a-box position="5 2 -10"></a-box>
</a-scene>
<script>
AFRAME.registerComponent('camera-path', {
init: function() {
var el = this.el;
var pathEl = document.querySelector('#path');
var curveEl = document.querySelector('#curve');
var camera = el.querySelector('[camera]');
var animation = document.createElement('a-animation');
animation.setAttribute('attribute', 'position');
animation.setAttribute('begin', 'click');
animation.setAttribute('easing', 'linear');
animation.setAttribute('dur', '5000');
animation.setAttribute('repeat', 'indefinite');
animation.setAttribute('to', '0 1.6 0');
el.appendChild(animation);
el.addEventListener('click', function() {
var points = curveEl.components.curve.points;
var currentPoint = camera.getAttribute('position');
var nextPoint = points.find(function(point) {
return point.x !== currentPoint.x && point.y !== currentPoint.y && point.z !== currentPoint.z;
});
if (nextPoint) {
var tween = new TWEEN.Tween(currentPoint)
.to(nextPoint, 5000)
.onUpdate(function() {
camera.setAttribute('position', currentPoint);
});
tween.start();
}
});
}
});
AFRAME.registerComponent('look-at', {
schema: { type: 'selector' },
init: function() {
var targetEl = this.data;
this.el.object3D.lookAt(targetEl.object3D.position);
},
tick: function() {
var targetEl = this.data;
this.el.object3D.lookAt(targetEl.object3D.position);
}
});
document.querySelector('[camera]').setAttribute('camera', 'userHeight: 1.6');
document.querySelector('[camera]').setAttribute('camera-path', '');
</script>
</body>

这段代码中,摄像机沿着三个方块构成的路径移动,并保持对每个方块的关注。点击场景中的任意位置,即可启动摄像机在路径上的动画效果。
