AnimationMode

描述

AnimationWindow 使用 AnimationMode 来存储 由 AnimationClip 播放修改的属性。

当退出 AnimationMode 时，所有属性都将 还原为其默认状态。动画属性也会在 Inspector 中突出显示。使用 StartAnimationMode 进入动画模式。在动画模式中， 编辑器会着色以显示它正在动画化。属性可以通过 SampleAnimationClip 进行动画化。\ \ 以下脚本示例显示了如何对游戏对象进行动画化。AnimationMode 具有 支持此功能的函数。演示可从“Examples/AnimationMode demo” 菜单启动。此演示开始后，它需要在 Scene 窗口中选择一个游戏对象。 （此示例要求不在 Game 视图中运行游戏。）选择 游戏对象后，示例窗口将会更改。为所选游戏对象 选择一个已创建的动画剪辑。在动画剪辑加载完成后， 动画便可应用于游戏对象。单击 Animate 按钮，将滑动条添加到 窗口。使用滑动条会将动画应用于所选的游戏对象。Lock 按钮可防止动画应用于其他游戏对象。
