This is extremely helpful for moving character's head to look at the player, rotating a turret to look at a target, or any other case where you want to make a bone rotate towards something quickly and easily. .. rst-class:: classref-reftable-group Properties ---------- .. table:: :widths: auto +---------------------------------+-------------------------------------------------------------------------------------+------------------+ | :ref:`NodePath` | :ref:`bone2d_node` | ``NodePath("")`` | +---------------------------------+-------------------------------------------------------------------------------------+------------------+ | :ref:`int` | :ref:`bone_index` | ``-1`` | +---------------------------------+-------------------------------------------------------------------------------------+------------------+ | :ref:`NodePath` | :ref:`target_nodepath` | ``NodePath("")`` | +---------------------------------+-------------------------------------------------------------------------------------+------------------+ .. rst-class:: classref-reftable-group Methods ------- .. table:: :widths: auto +---------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------+ | :ref:`float` | :ref:`get_additional_rotation`\ (\ ) |const| | +---------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------+ | :ref:`bool` | :ref:`get_constraint_angle_invert`\ (\ ) |const| | +---------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------+ | :ref:`float` | :ref:`get_constraint_angle_max`\ (\ ) |const| | +---------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------+ | :ref:`float` | :ref:`get_constraint_angle_min`\ (\ ) |const| | +---------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------+ | :ref:`bool` | :ref:`get_enable_constraint`\ (\ ) |const| | +---------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------+ | |void| | :ref:`set_additional_rotation`\ (\ rotation\: :ref:`float`\ ) | +---------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------+ | |void| | :ref:`set_constraint_angle_invert`\ (\ invert\: :ref:`bool`\ ) | +---------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------+ | |void| | :ref:`set_constraint_angle_max`\ (\ angle_max\: :ref:`float`\ ) | +---------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------+ | |void| | :ref:`set_constraint_angle_min`\ (\ angle_min\: :ref:`float`\ ) | +---------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------+ | |void| | :ref:`set_enable_constraint`\ (\ enable_constraint\: :ref:`bool`\ ) | +---------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------+ .. rst-class:: classref-section-separator ---- .. rst-class:: classref-descriptions-group Property Descriptions --------------------- .. _class_SkeletonModification2DLookAt_property_bone2d_node: .. rst-class:: classref-property :ref:`NodePath` **bone2d_node** = ``NodePath("")`` :ref:`🔗` .. rst-class:: classref-property-setget -

This allows for offsetting the results by the inputted rotation amount. .. rst-class:: classref-item-separator ---- .. _class_SkeletonModification2DLookAt_method_set_constraint_angle_invert: .. rst-class:: classref-method |void| **set_constraint_angle_invert**\ (\ invert\: :ref:`bool`\ ) :ref:`🔗` When ``true``, the modification will use an inverted joint constraint. An inverted joint constraint only constraints the :ref:`Bone2D` to the angles *outside of* the inputted minimum and maximum angles. For this reason, it is referred to as an inverted joint constraint, as it constraints the joint to the outside of the inputted values. .. rst-class:: classref-item-separator ---- .. _class_SkeletonModification2DLookAt_method_set_constraint_angle_max: .. rst-class:: classref-method |void| **set_constraint_angle_max**\ (\ angle_max\: :ref:`float`\ ) :ref:`🔗` Sets the constraint's maximum allowed angle. .. rst-class:: classref-item-separator ---- .. _class_SkeletonModification2DLookAt_method_set_constraint_angle_min: .. rst-class:: classref-method |void| **set_constraint_angle_min**\ (\ angle_min\: :ref:`float`\ ) :ref:`🔗` Sets the constraint's minimum allowed angle. .. rst-class:: classref-item-separator ---- .. _class_SkeletonModification2DLookAt_method_set_enable_constraint: .. rst-class:: classref-method |void| **set_enable_constraint**\ (\ enable_constraint\: :ref:`bool`\ ) :ref:`🔗` Sets whether this modification will use constraints or not. When ``true``, constraints will be applied when solving the LookAt modification. .. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)` .. |const| replace:: :abbr:`const (This method has no side effects.
