Description
|
|
-----------
|
|
|
|
Event-based Hierarchical State Machine (HSM) that manages :ref:`LimboState<class_LimboState>` instances and facilitates transitions between them. LimboHSM is a :ref:`LimboState<class_LimboState>` in itself and can also serve as a child of another LimboHSM node.

|
|
|
|
void **initialize** **(** Node p_agent, :ref:`Blackboard<class_Blackboard>` p_parent_scope=null **)**
|

|
|
.. rst-class:: classref-method
|
|

|
void **set_active** **(** bool p_active **)**
|
|
|
|
When set to ``true``, switches the state to :ref:`initial_state<class_LimboHSM_property_initial_state>` and activates state processing according to :ref:`update_mode<class_LimboHSM_property_update_mode>`.

|
|
|
|
Calls :ref:`LimboState._update<class_LimboState_private_method__update>` on itself and the active substate, with the call cascading down to the leaf state. This method is automatically triggered if :ref:`update_mode<class_LimboHSM_property_update_mode>` is not set to :ref:`MANUAL<class_LimboHSM_constant_MANUAL>`.
