我已经尝试了太多但结果相同，当自定义事件触发 a 帧中的动画时，它以相同的方式从 (x,y,z) 播放该动画到 (x',y',z')从 (x'',y'',z'') 到 (x',y',z') 我试过 a-animation 属性，但从来没有找到解决方案!

Javascript:
var one = document.querySelector('#one');
var two = document.querySelector('#two');
var three = document.querySelector('#three');
one.addEventListener('click', function () {
camera.emit('one');
});
two.addEventListener('click', function () {
camera.emit('two');
});
three.addEventListener('click', function () {
camera.emit('three');
});
这是 codepen 中的测试: http://codepen.io/anon/pen/OXaoKg
最佳答案
这里的部分问题是重复触发点击。我们可以这样控制:
var at = "one";
one.addEventListener('click', function () {
if( at !== "one") {
at = "one";
camera.emit('one');
}
});
two.addEventListener('click', function () {
if( at !== "two") {
at = "two";
camera.emit('two');
}
});
three.addEventListener('click', function () {
if( at !== "three") {
at = "three";
camera.emit('three');
}
});
