在 A 帧中同时制作两个动画 [英] making two animations at once in A-frame

问题描述

例如，通过使用相机装备，我想通过单击从 A 移动到 B，然后从 B 移动到 C.我通常写to 0 0 0"在onclick"事件中.

For example, by using camera rig, I want to move from A to B then B to C in just one single click. I normally write "to 0 0 0" in the event "onclick".

我想触发两个动画1"和1_1".目前只有1_1"这是由点击触发的.我正在使用来自 https://www.npmjs.com/package 的时间线/aframe-animation-timeline-component

I want trigger both animations "1" and "1_1". At the moment it is only the "1_1" that is triggered by a click. I'm using a timeline from https://www.npmjs.com/package/aframe-animation-timeline-component

我的代码可以在 https://glitch.com/edit/中找到#!/winter-deserted-topaz

推荐答案

这个话题很笼统，所以我把它分成不同的案例:

The topic is general, so I'll split it into separate cases:

1. 同时触发两个动画

如果实体内的动画组件共享一个事件(定义在 startEvents ) 它们会同时触发:

If the animation components within an entity share an event ( defined in startEvents ) they will all fire at once:

    <script src="https://aframe.io/releases/1.2.0/aframe.min.js"></script>
    <a-scene cursor="rayOrigin: mouse">
      <a-box position="0 1 -3" rotation="0 45 0" scale="0.25 0.25 0.25" color="#4CC3D9" 

      animation__rotation="property: rotation; from: 0 45 0; to: 0 405 0; dur: 4000; 
      easing: linear; startEvents: click" 

      animation__scale="property: scale; from: 0.25 0.25 0.25; to: 1.5 1.5 1.5; dur: 2000; 
      dir: alternate; easing: linear; loop: 2; startEvents: click">
      </a-box>
    </a-scene>

在另一个动画完成后开始动画

您可以等待一个动画完成，然后使用一些 javascript 开始另一个动画.

You can wait for one animation to finish and start another one with a bit of javascript.

您可以通过 animationcomplete__(ID 是 animation__ 位之后的名称"字符串)事件.

You can determine if an animation has ended with the animationcomplete__(ID is the 'name' string after the animation__ bit) event.

然后你可以发出一个信号，开始第二个动画:

Then you can emit a signal, which starts the second animation:

    <script src="https://aframe.io/releases/1.2.0/aframe.min.js"></script>
    <script>
      AFRAME.registerComponent("animation-manager", {
        init: function() {
          // wait for the first animation to finish
          this.el.addEventListener("animationcomplete__first", e => {
            // start the second animation
            this.el.emit("second")
          })
        }
      })
    </script>
    <a-scene cursor="rayOrigin: mouse">
      <a-box position="0 1 -3" rotation="0 45 0" scale="0.25 0.25 0.25" animation-manager color="#4CC3D9" 
      animation__first="property: rotation; from: 0 45 0; to: 0 405 0; dur: 2000; 
      easing: linear; startEvents: click" 
      animation__second="property: scale; from: 0.25 0.25 0.25; to: 1.5 1.5 1.5; dur: 2000; 
      dir: alternate; easing: linear; loop: 2; startEvents: second">
      </a-box>
    </a-scene>
