<brief_description>
|
|
A node containing a bone hierarchy, used to create a 3D skeletal animation.
|
|
</brief_description>
|
|
<description>
|
|
[Skeleton3D] provides an interface for managing a hierarchy of bones, including pose, rest and animation (see [Animation]). It can also use ragdoll physics.
|
|
The overall transform of a bone with respect to the skeleton is determined by bone pose. Bone rest defines the initial transform of the bone pose.
|
|
Note that "global pose" below refers to the overall transform of the bone with respect to skeleton, so it is not the actual global/world transform of the bone.
|
|
To setup different types of inverse kinematics, consider using [SkeletonIK3D], or add a custom IK implementation in [method Node._process] as a child node.

[param amount] is the interpolation strength that will be used when applying the pose, and [param persistent] determines if the applied pose will remain.
|
|
[b]Note:[/b] The pose transform needs to be a global pose! To convert a world transform from a [Node3D] to a global bone pose, multiply the [method Transform3D.affine_inverse] of the node's [member Node3D.global_transform] by the desired world transform.
