AnimationMode.IsPropertyAnimated

切换到手册
public static bool IsPropertyAnimated (Object target, string propertyPath);

参数

target 用于确定是否包含动画的对象。
propertyPath 要搜索的动画的名称。

返回

bool 是否找到了属性搜索项。

描述

Checks whether the specified property is in Animation mode and is being animated.

IsPropertyAnimated 检查属性是否正在动画化。该 检查还需要包含此属性的对象。

在以下脚本示例中搜索 Renderer。它是 Renderer 对象的一部分。 请注意，该示例使用了一个球体游戏对象和一个动画文件 color.anim。color.anim 中的 颜色动画具有从黄到蓝的颜色变化。 

// 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.
