bool	autostart	false
bool	one_shot	false
bool	paused
TimerProcessMode	process_mode	1
float	time_left
float	wait_time	1.0

Methods

bool	is_stopped ( ) const
void	start ( float time_sec=-1 )
void	stop ( )

Signals

• timeout ( )

Emitted when the timer reaches 0.

Enumerations

enum TimerProcessMode:

• TIMER_PROCESS_PHYSICS = 0 — Update the timer during the physics step at each frame (fixed framerate processing).
• TIMER_PROCESS_IDLE = 1 — Update the timer during the idle time at each frame.

Property Descriptions

• bool autostart

Default	false
Setter	set_autostart(value)
Getter	has_autostart()

If true, the timer will automatically start when entering the scene tree.

Note: This property is automatically set to false after the timer enters the scene tree and starts.

---

• bool one_shot

Default	false
Setter	set_one_shot(value)
Getter	is_one_shot()

If true, the timer will stop when reaching 0. If false, it will restart.

---

• bool paused

Setter	set_paused(value)
Getter	is_paused()

If true, the timer is paused and will not process until it is unpaused again, even if start is called.

---

• TimerProcessMode process_mode

Default	1
Setter	set_timer_process_mode(value)
Getter	get_timer_process_mode()

Processing mode. See TimerProcessMode.

---

• float time_left

Getter

get_time_left()

The timer’s remaining time in seconds. Returns 0 if the timer is inactive.

Note: You cannot set this value. To change the timer’s remaining time, use start.

---

• float wait_time

Default	1.0
Setter	set_wait_time(value)
Getter	get_wait_time()

Wait time in seconds.

Method Descriptions

• bool is_stopped ( ) const

Returns true if the timer is stopped.

---

• void start ( float time_sec=-1 )

Starts the timer. Sets wait_time to time_sec if time_sec > 0. This also resets the remaining time to wait_time.

Note: this method will not resume a paused timer. See paused.

---

• void stop ( )

Stops the timer.
