А node that dynamically copies or overrides the 3D transform of a bone in its parent [Skeleton3D]. This node selects a bone in a [Skeleton3D] and attaches to it. This means that the [BoneAttachment3D] node will either dynamically copy or override the 3D transform of the selected bone. Returns the [NodePath] to the external [Skeleton3D] node, if one has been set. Returns whether the BoneAttachment3D node is using an external [Skeleton3D] rather than attempting to use its parent node as the [Skeleton3D]. A function that is called automatically when the [Skeleton3D] the BoneAttachment3D node is using has a bone that has changed its pose. This function is where the BoneAttachment3D node updates its position so it is correctly bound when it is [i]not[/i] set to override the bone pose. Sets the [NodePath] to the external skeleton that the BoneAttachment3D node should use. See [method set_use_external_skeleton] to enable the external [Skeleton3D] node. Sets whether the BoneAttachment3D node will use an external [Skeleton3D] node rather than attempting to use its parent node as the [Skeleton3D]. When set to [code]true[/code], the BoneAttachment3D node will use the external [Skeleton3D] node set in [method set_external_skeleton]. The index of the attached bone. The name of the attached bone. Whether the BoneAttachment3D node will override the bone pose of the bone it is attached to. When set to [code]true[/code], the BoneAttachment3D node can change the pose of the bone. When set to [code]false[/code], the BoneAttachment3D will always be set to the bone's transform.
