AnimationMode.IsPropertyAnimated

パラメーター

戻り値

bool Whether the property search is found or not.

説明

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

IsPropertyAnimated checks whether a property is being animated. This check requires also the object where the property can be found.

color is searched for in the following script example . It is part of the Renderer object. Note that the example uses a sphere GameObject and an animation file, color.anim. The color animation in color.anim has the color varying from yellow to blue.

// 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.
