			<argument index="0" name="p_event" type="String" />
			<argument index="1" name="p_method" type="String" />
			<description>
				Register [code]p_method[/code] that will be called when [code]p_event[/code] happens. Method must belong to the state.
			</description>

		<method name="call_on_enter">
			<return type="LimboState" />
			<argument index="0" name="p_object" type="Object" />
			<argument index="1" name="p_method" type="String" />
			<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" />
			<argument index="0" name="p_object" type="Object" />
			<argument index="1" name="p_method" type="String" />
			<description>

		<method name="call_on_update">
			<return type="LimboState" />
			<argument index="0" name="p_object" type="Object" />
			<argument index="1" name="p_method" type="String" />
			<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_func">
			<return type="void" />
			<description>
				Removes the guard function that was set by [method set_guard_func].
			</description>
		</method>
		<method name="dispatch">
			<return type="bool" />
			<argument index="0" name="p_event" type="String" />
			<argument 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.
			</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" />
			<argument index="0" name="p_name" type="String" />
			<description>
				A chained method that sets the name of this state.
			</description>
		</method>
		<method name="set_guard_func">
			<return type="void" />
			<argument index="0" name="p_object" type="Object" />
			<argument index="1" name="p_func" type="String" />
			<argument index="2" name="p_binds" type="Array" default="[  ]" />
			<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], that transition will not be allowed.
			</description>
