Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
A LimboAI state node for Hierarchical State Machines (HSM).
|
||
|
|
|
||
|
|
You can create your state behavior by extending this class. To implement your state logic, you can override :ref:`_enter<class_LimboState_private_method__enter>`, :ref:`_exit<class_LimboState_private_method__exit>`, :ref:`_setup<class_LimboState_private_method__setup>`, and :ref:`_update<class_LimboState_private_method__update>`. Alternatively, you can delegate state implementation to external methods using the ``call_on_*`` methods.
|
||
|
|
|
||
|
|
For additional details on state machines, refer to :ref:`LimboHSM<class_LimboHSM>`.

bool **dispatch** **(** String p_event, Variant p_cargo=null **)**

Events propagate from the leaf state to the root state, and propagation stops as soon as any state consumes the event. States will consume the event if they have a related transition or event handler. For more information on event handlers, see :ref:`add_event_handler<class_LimboState_method_add_event_handler>`.
