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.

animatedPropertyColor | The color used to show that a property is currently being animated. |
AddPropertyModification | Marks a property as currently being animated. |
BeginSampling | Initialise the start of the animation clip sampling. |
EndSampling | Finish the sampling of the animation clip. |
InAnimationMode | Are we currently in AnimationMode? |
IsPropertyAnimated | Is the specified property currently in animation mode and being animated? |
SampleAnimationClip | Samples an AnimationClip on the object and also records any modified properties in AnimationMode. |
StartAnimationMode | Starts the animation mode. |
StopAnimationMode | Stops Animation mode, reverts all properties that were animated in animation mode. |
