AnimationMode.IsPropertyAnimated

参数

返回

bool 是否找到属性搜索。

描述

检查指定的属性是否处于动画模式并正在被动画化。

IsPropertyAnimated 检查属性是否正在被动画化。此检查还需要可以找到属性的对象。

在以下脚本示例中搜索 color。它是 Renderer 对象的一部分。请注意，该示例使用球体 GameObject 和动画文件 color.anim。color.anim 中的颜色动画的颜色从黄色变为蓝色。

// Demo showing how IsPropertyAnimated() can be used to determine if a property
// on an object is being animated. In this example the color in a Renderer is
// animated.
