Skeleton3D
A node containing a bone hierarchy, used to create a 3D skeletal animation.
描述
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.

信号
bone_enabled_changed ( bone_idx: int )
Emitted when the bone at bone_idx is toggled with set_bone_enabled. Use is_bone_enabled to check the new value.
bone_list_changed ( )
该信号目前没有描述，请帮我们\ :ref:贡献一个 <doc_updating_the_class_reference>\ 吧 ！
pose_updated ( )
Emitted when the pose is updated.
Note: During the update process, this signal is not fired, so modification by SkeletonModifier3D is not detected.
show_rest_only_changed ( )
Emitted when the value of show_rest_only changes.
skeleton_updated ( )
Emitted when the final pose has been calculated will be applied to the skin in the update process.
This means that all SkeletonModifier3D processing is complete. In order to detect the completion of the processing of each SkeletonModifier3D, use SkeletonModifier3D.modification_processed.
枚举
enum ModifierCallbackModeProcess:
ModifierCallbackModeProcess MODIFIER_CALLBACK_MODE_PROCESS_PHYSICS = 0
Set a flag to process modification during physics frames (see Node.NOTIFICATION_INTERNAL_PHYSICS_PROCESS).
ModifierCallbackModeProcess MODIFIER_CALLBACK_MODE_PROCESS_IDLE = 1
Set a flag to process modification during process frames (see Node.NOTIFICATION_INTERNAL_PROCESS).
常量
NOTIFICATION_UPDATE_SKELETON = 50
Notification received when this skeleton's pose needs to be updated. In that case, this is called only once per frame in a deferred process.
属性说明
bool animate_physical_bones = true
已弃用： 未来版本中可能会修改或移除该属性。
If you follow the recommended workflow and explicitly have PhysicalBoneSimulator3D as a child of Skeleton3D, you can control whether it is affected by raycasting without running physical_bones_start_simulation, by its SkeletonModifier3D.active.
However, for old (deprecated) configurations, Skeleton3D has an internal virtual PhysicalBoneSimulator3D for compatibility. This property controls the internal virtual PhysicalBoneSimulator3D's SkeletonModifier3D.active.
ModifierCallbackModeProcess modifier_callback_mode_process = 1
voidset_modifier_callback_mode_process ( value: ModifierCallbackModeProcess )- ModifierCallbackModeProcess get_modifier_callback_mode_process ( )
Sets the processing timing for the Modifier.
float motion_scale = 1.0
Multiplies the 3D position track animation.
Note: Unless this value is 1.0, the key value in animation will not match the actual position value.
bool show_rest_only = false
If true, forces the bones in their default rest pose, regardless of their values. In the editor, this also prevents the bones from being edited.
方法说明
Adds a new bone with the given name. Returns the new bone's index, or -1 if this method fails.
Note: Bone names should be unique, non empty, and cannot include the : and / characters.
void clear_bones ( )
Clear all the bones in this skeleton.
void clear_bones_global_pose_override ( )
已弃用： 未来版本中可能会修改或移除该方法。
Removes the global pose override on all bones in the skeleton.

Note: This is the global pose you set to the skeleton in the process, the final global pose can get overridden by modifiers in the deferred process, if you want to access the final global pose, use SkeletonModifier3D.modification_processed.
Transform3D get_bone_global_pose_no_override ( bone_idx: int ) const1
已弃用： 未来版本中可能会修改或移除该方法。
Returns the overall transform of the specified bone, with respect to the skeleton, but without any global pose overrides. Being relative to the skeleton frame, this is not the actual "global" transform of the bone.

String get_bone_name ( bone_idx: int ) const1
Returns the name of the bone at index bone_idx.
int get_bone_parent ( bone_idx: int ) const1

Note: The parent bone returned will always be less than bone_idx.
Transform3D get_bone_pose ( bone_idx: int ) const1
Returns the pose transform of the specified bone.
Note: This is the pose you set to the skeleton in the process, the final pose can get overridden by modifiers in the deferred process, if you want to access the final pose, use SkeletonModifier3D.modification_processed.
Vector3 get_bone_pose_position ( bone_idx: int ) const1
Returns the pose position of the bone at bone_idx. The returned Vector3 is in the local coordinate space of the Skeleton3D node.
Quaternion get_bone_pose_rotation ( bone_idx: int ) const1
Returns the pose rotation of the bone at bone_idx. The returned Quaternion is local to the bone with respect to the rotation of any parent bones.

Transform3D get_bone_rest ( bone_idx: int ) const1
Returns the rest transform for a bone bone_idx.
StringName get_concatenated_bone_names ( ) const1
Returns all bone names concatenated with commas (,) as a single StringName.
It is useful to set it as a hint for the enum property.

void set_bone_global_pose ( bone_idx: int, pose: Transform3D )
Sets the global pose transform, pose, for the bone at bone_idx.
Note: If other bone poses have been changed, this method executes a dirty poses recalculation and will cause performance to deteriorate. If you know that multiple global poses will be applied, consider using set_bone_pose with precalculation.
void set_bone_global_pose_override ( bone_idx: int, pose: Transform3D, amount: float, persistent: bool = false )
已弃用： 未来版本中可能会修改或移除该方法。
Sets the global pose transform, pose, for the bone at bone_idx.
amount is the interpolation strength that will be used when applying the pose, and persistent determines if the applied pose will remain.
Note: The pose transform needs to be a global pose! To convert a world transform from a Node3D to a global bone pose, multiply the Transform3D.affine_inverse of the node's Node3D.global_transform by the desired world transform.
