</method>
<method name="add_event_handler">
<return type="void" />
<param index="0" name="p_event" type="String" />
<param index="1" name="p_handler" type="Callable" />
<description>
Register [code]p_method[/code] that will be called when [code]p_event[/code] happens. Method must belong to the state.
</description>
</method>
<method name="call_on_enter">
<return type="LimboState" />
<param index="0" name="p_callable" type="Callable" />
<description>
A chained method that connects [signal entered] signal to a [code]p_method[/code] on a [p_object].
</description>
</method>
<method name="call_on_exit">
<return type="LimboState" />
<param index="0" name="p_callable" type="Callable" />
<description>
A chained method that connects [signal exited] signal to a [code]p_method[/code] on a [p_object].
</description>
</method>
<method name="call_on_update">
<return type="LimboState" />
<param index="0" name="p_callable" type="Callable" />
<description>
A chained method that connects [signal updated] signal to a [code]p_method[/code] on a [p_object].
</description>
</method>
<method name="clear_guard">
<return type="void" />
<description>
Removes state's guard function that was set by [method set_guard].
</description>
</method>
<method name="dispatch">
<return type="bool" />
<param index="0" name="p_event" type="String" />
<param index="1" name="p_cargo" type="Variant" default="null" />
<description>
Dispatches recursively a state machine event named [code]p_event[/code] with an optional argument [code]p_cargo[/code]. Returns [code]true[/code] if event was consumed.
Events propagate from the leaf state to the root. Propagation stops as soon as some state consumes the event. States will consume event if they have a transition associated with it, or an event handler. See also [method add_event_handler].
</description>
</method>
<method name="get_root" qualifiers="const">
<return type="LimboState" />
<description>
Returns the root [LimboState].
</description>
</method>
<method name="is_active" qualifiers="const">
<return type="bool" />
<description>
Returns [code]true[/code] if it is currently active, i.e. it is the active substate of the parent [LimboHSM].
</description>
</method>
<method name="named">
<return type="LimboState" />
<param index="0" name="p_name" type="String" />
<description>
A chained method that sets the name of this state.
</description>
</method>
<method name="set_guard">
<return type="void" />
<param index="0" name="p_guard_callable" type="Callable" />
<description>
Sets the guard function. It is a function that will be called each time a transition to this state should happen. If that function returns [code]false[/code], the transition will not be allowed.
</description>
</method>
