A resource that operates on [Bone2D] nodes in a [Skeleton2D]. This resource provides an interface that can be expanded so code that operates on [Bone2D] nodes in a [Skeleton2D] can be mixed and matched together to create complex interactions. This is used to provide Godot with a flexible and powerful Inverse Kinematics solution that can be adapted for many different uses. Used for drawing [b]editor-only[/b] modification gizmos. This function will only be called in the Godot editor and can be overridden to draw custom gizmos. [b]Note:[/b] You will need to use the Skeleton2D from [method SkeletonModificationStack2D.get_skeleton] and it's draw functions, as the [SkeletonModification2D] resource cannot draw on its own. Returns whether this modification will call [method _draw_editor_gizmo] in the Godot editor to draw modification-specific gizmos. Returns whether this modification has been successfully setup or not. Returns the [SkeletonModificationStack2D] that this modification is bound to. Through the modification stack, you can access the Skeleton3D the modification is operating on. If [code]true[/code], the modification's [method _execute] function will be called by the [SkeletonModificationStack2D]. The execution mode for the modification. This tells the modification stack when to execute the modification. Some modifications have settings that are only available in certain execution modes.
