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>`.

|
|
::
|
|
|
|
func my_event_handler(cargo=null) -> bool:
|
|
|
|
If the handler returns ``true``, the event will be consumed. Cargo is an optional parameter that can be passed to the handler. See also :ref:`dispatch<class_LimboState_method_dispatch>`.

``bool`` **dispatch**\ (\ event\: ``StringName``, cargo\: ``Variant`` = null\ ) :ref:`🔗<class_LimboState_method_dispatch>`
|
|
|
|
Recursively dispatches a state machine event named ``event`` with an optional argument ``cargo``. Returns ``true`` if the event was consumed.
|
|
|
|
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>`.
