AnimationMode

Description

AnimationMode is used by the AnimationWindow to store properties modified by the AnimationClip playback.

When exiting AnimationMode all properties are reverted to their default state. Animated properties are also highlighted by the inspector. Use StartAnimationMode to enter animation mode. In Animation mode the editor is tinted to show that it is animating. Properties can be animated via SampleAnimationClip.

The following script example shows how a GameObject can be animated. AnimationMode has functions which support this. The demo can be launched from the "Examples/AnimationMode demo" menu. Once this demo starts it requires a GameObject to be selected in the Scene window. (This example requires the game to not be running in the Game view.) After a GameObject has been selected the example window will change. Choose a created animation clip for the chosen GameObject. Once the animation clip has been loaded the animation can be applied to the GameObject. Clicking the Animate button adds a slider to the window. Using the slider will apply the animation to the selected GameObject. The Lock button prevents the animation to be applied to a different GameObject.
