|
* The Spine GameObject is a thin wrapper around a Spine {@link Skeleton}, {@link AnimationState} and {@link AnimationStateData}. It is responsible for:
|
|
|
* - updating the animation state
|
|
|
* - applying the animation state to the skeleton's bones, slots, attachments, and draw order.
|
|
|
* - updating the skeleton's bone world transforms
|
|
|
* - rendering the skeleton
|
|
|

|
|
* See the {@link SpinePlugin} class for more information on how to create a `SpineGameObject`.
|
|
|
- *
|
|
|

|
|
|
* The skeleton, animation state, and animation state data can be accessed via the repsective fields. They can be manually updated via {@link updatePose}.
|
|
|
- *
|
|
|

|
|
|
* To modify the bone hierarchy before the world transforms are computed, a callback can be set via the {@link beforeUpdateWorldTransforms} field.
