<brief_description>
Skeleton for 2D characters and animated objects.
</brief_description>
<description>
Skeleton2D parents a hierarchy of [Bone2D] objects. It is a requirement of [Bone2D]. Skeleton2D holds a reference to the rest pose of its children and acts as a single point of access to its bones.

<return type="void">
</return>
<argument index="0" name="delta" type="float">
</argument>
<argument index="1" name="execution_mode" type="int">
</argument>
<description>
Executes all the modifications on the [SkeletonModificationStack2D], if the Skeleton3D has one assigned.
</description>
</method>
<method name="get_bone">
<return type="Bone2D">
</return>
<argument index="0" name="idx" type="int">
</argument>
<description>
Returns a [Bone2D] from the node hierarchy parented by Skeleton2D. The object to return is identified by the parameter [code]idx[/code]. Bones are indexed by descending the node hierarchy from top to bottom, adding the children of each branch before moving to the next sibling.
</description>
</method>
<method name="get_bone_count" qualifiers="const">
<return type="int">
</return>
<description>
Returns the number of [Bone2D] nodes in the node hierarchy parented by Skeleton2D.
</description>
</method>
<method name="get_bone_local_pose_override">
<return type="Transform2D">
</return>
<argument index="0" name="bone_idx" type="int">
</argument>
<description>
Returns the local pose override transform for [code]bone_idx[/code].
</description>
</method>
<method name="get_modification_stack" qualifiers="const">
<return type="SkeletonModificationStack2D">
</return>
<description>
Returns the [SkeletonModificationStack2D] attached to this skeleton, if one exists.
</description>
</method>
<method name="get_skeleton" qualifiers="const">
<return type="RID">
</return>
<description>
Returns the [RID] of a Skeleton2D instance.

</argument>
<argument index="2" name="strength" type="float">
</argument>
<argument index="3" name="persistent" type="bool">
</argument>
<description>
Sets the local pose transform, [code]pose[/code], for the bone at [code]bone_idx[/code].
[code]amount[/code] is the interpolation strength that will be used when applying the pose, and [code]persistent[/code] determines if the applied pose will remain.
[b]Note:[/b] The pose transform needs to be a local transform relative to the [Bone2D] node at [code]bone_idx[/code]!

<argument index="0" name="modification_stack" type="SkeletonModificationStack2D">
</argument>
<description>
Sets the [SkeletonModificationStack2D] attached to this skeleton.
</description>
</method>
</methods>
<signals>
<signal name="bone_setup_changed">
<description>
Emitted when the [Bone2D] setup attached to this skeletons changes. This is primarily used internally within the skeleton.
