	<brief_description>
		A countdown timer.
	</brief_description>
	<description>
		Counts down a specified interval and emits a signal on reaching 0. Can be set to repeat or "one-shot" mode.
		[b]Note:[/b] To create a one-shot timer without instantiating a node, use [method SceneTree.create_timer].

	<methods>
		<method name="is_stopped" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if the timer is stopped.
			</description>
		</method>
		<method name="start">
			<return type="void" />
			<argument index="0" name="time_sec" type="float" default="-1" />
			<description>
				Starts the timer. Sets [code]wait_time[/code] to [code]time_sec[/code] if [code]time_sec &gt; 0[/code]. This also resets the remaining time to [code]wait_time[/code].
				[b]Note:[/b] This method will not resume a paused timer. See [member paused].
			</description>
		</method>
		<method name="stop">
			<return type="void" />
			<description>
				Stops the timer.

	<members>
		<member name="autostart" type="bool" setter="set_autostart" getter="has_autostart" default="false">
			If [code]true[/code], the timer will automatically start when entering the scene tree.
			[b]Note:[/b] This property is automatically set to [code]false[/code] after the timer enters the scene tree and starts.
		</member>
		<member name="one_shot" type="bool" setter="set_one_shot" getter="is_one_shot" default="false">
			If [code]true[/code], the timer will stop when reaching 0. If [code]false[/code], it will restart.
		</member>
		<member name="paused" type="bool" setter="set_paused" getter="is_paused">
			If [code]true[/code], the timer is paused and will not process until it is unpaused again, even if [method start] is called.
		</member>
		<member name="process_mode" type="int" setter="set_timer_process_mode" getter="get_timer_process_mode" enum="Timer.TimerProcessMode" default="1">
			Processing mode. See [enum TimerProcessMode].
		</member>
		<member name="time_left" type="float" setter="" getter="get_time_left">
			The timer's remaining time in seconds. Returns 0 if the timer is inactive.
			[b]Note:[/b] You cannot set this value. To change the timer's remaining time, use [method start].
		</member>
		<member name="wait_time" type="float" setter="set_wait_time" getter="get_wait_time" default="1.0">
			The wait time in seconds.
			[b]Note:[/b] Timers can only emit once per rendered frame at most (or once per physics frame if [member process_mode] is [constant TIMER_PROCESS_PHYSICS]). This means very low wait times (lower than 0.05 seconds) will behave in significantly different ways depending on the rendered framerate. For very low wait times, it is recommended to use a process loop in a script instead of using a Timer node.
