Property Descriptions
---------------------

.. _class_BlackboardPlan_property_prefetch_nodepath_vars:

.. rst-class:: classref-property

bool **prefetch_nodepath_vars** = ``true``

.. rst-class:: classref-property-setget

- void **set_prefetch_nodepath_vars** **(** bool value **)**
- bool **is_prefetching_nodepath_vars** **(** **)**

Enables or disables ``NodePath`` variable prefetching. If ``true``, ``NodePath`` values will be replaced with node instances when the :ref:`Blackboard<class_Blackboard>` is created.

Method Descriptions
-------------------

.. _class_BlackboardPlan_method_create_blackboard:

.. rst-class:: classref-method

:ref:`Blackboard<class_Blackboard>` **create_blackboard** **(** Node node **)**

Constructs a new instance of a :ref:`Blackboard<class_Blackboard>` using this plan. If ``NodePath`` prefetching is enabled, ``node`` will be used to retrieve node instances for ``NodePath`` variables and substitute their values.

.. rst-class:: classref-item-separator

----

.. _class_BlackboardPlan_method_get_base_plan:

.. rst-class:: classref-method

:ref:`BlackboardPlan<class_BlackboardPlan>` **get_base_plan** **(** **)** |const|

Returns the base plan. See :ref:`is_derived<class_BlackboardPlan_method_is_derived>`.

.. rst-class:: classref-item-separator

----

.. _class_BlackboardPlan_method_is_derived:

.. rst-class:: classref-method

bool **is_derived** **(** **)** |const|

Returns ``true`` if this plan is derived from another, i.e., the base plan is not ``null``. A derived plan can only contain variables that are present in the base plan, and only variable values can be different.

.. rst-class:: classref-item-separator

----

.. _class_BlackboardPlan_method_populate_blackboard:

.. rst-class:: classref-method

void **populate_blackboard** **(** :ref:`Blackboard<class_Blackboard>` blackboard, bool overwrite, Node node **)**

Populates ``blackboard`` with the variables from this plan. If ``overwrite`` is ``true``, existing variables with the same names will be overwritten. If ``NodePath`` prefetching is enabled, ``node`` will be used to retrieve node instances for ``NodePath`` variables and substitute their values.

.. rst-class:: classref-item-separator

----

.. _class_BlackboardPlan_method_set_base_plan:

.. rst-class:: classref-method

void **set_base_plan** **(** :ref:`BlackboardPlan<class_BlackboardPlan>` blackboard_plan **)**

Sets the base plan. If assigned, this plan will be derived from the base plan.

Use with caution, as it will remove variables not present in the base plan. Only use this for custom tooling.

.. rst-class:: classref-item-separator

----

.. _class_BlackboardPlan_method_sync_with_base_plan:

.. rst-class:: classref-method

void **sync_with_base_plan** **(** **)**

Synchronizes this plan with the base plan: removes variables not present in the base plan, and updates type information. Only use this for custom tooling.

.. |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. It doesn't modify any of the instance's member variables.)`
