    • type -- The animationtype for the key. Can be "pos", "rot" and "scl".键的动画类型。可以是“pos”、“rot”和“scl”。
    • h -- The object of the hierarchy that contains the key. 包含键的层次结构的对象。
    • key -- The index of the prev possible key.上一个可能键的索引。 Gets the previous key. Is used in Update.获取上一个键。在更新中使用。

动画处理器(AnimationHandler)

The AnimationHandler handles the initialisation of the Animation data and the animations itself. It keeps track of every animation and if it's active or not. It also update all animations which are active if its method update is called.

AnimationHandler处理动画数据和动画本身的初始化。它跟踪每一个动画，不管它是否处于活动状态。如果调用了方法更新，它也会更新所有活动的动画。

源码

构造器（Constructor）

AnimationHandler()

The animationHandler can't be called as constructor.

Enum Value to indicate that the animation needs to be interpolated as LINEAR.枚举值以指示动画需要作为线性插值。

方法（Methods）

  • .removeFromUpdate (animation)
    • animation -- The Animation to remove from the update.要从更新中删除的动画。

Removes the animation from the update cycle. This gets called when the animation stops. This shouldn't be called by usercode.

从更新周期中删除动画。当动画停止时调用此函数。这不应该由用户代码调用。

  • .get (name)
    • name -- The name of the animationData。动画数据名称

Gets the animationData from its library.从其库中获取AnimationData。

  • .update (deltaTimeMS)
    • deltaTimeMS -- Time elapsed since last update in milliseconds.自上次更新以来经过的时间（毫秒）。

Updates all active animations with deltaTime.用Deltatime更新所有活动动画。

  • .parse (root)

    • root -- object Parses the object to get the hierachy.解析对象以获取层次结构。

  • .add (data)

    • data -- The animationData Adds the animationData from its library.从其库中添加动画数据。

  • .addToUpdate (animation)

    • animation -- The Animation to add from the update.要从更新中添加的动画。

Adds the animation from the update cycle. This gets called when the animation starts. This shouldn't be called by user code.

从更新周期添加动画。当动画开始时调用此函数。这不应该由用户代码调用。

关键帧动画(KeyFrameAnimation)

Runs a keyframe animation as imported from the ColladaLoader.
