A countdown timer. The [Timer] node is a countdown timer and is the simplest way to handle time-based logic in the engine. When a timer reaches the end of its [member wait_time], it will emit the [signal timeout] signal. After a timer enters the tree, it can be manually started with [method start]. A timer node is also started automatically if [member autostart] is [code]true[/code]. Without requiring much code, a timer node can be added and configured in the editor. The [signal timeout] signal it emits can also be connected through the Node dock in the editor: [codeblock] func _on_timer_timeout(): print("Time to attack!") [/codeblock] [b]Note:[/b] To create a one-shot timer without instantiating a node, use [method SceneTree.create_timer]. [b]Note:[/b] Timers are affected by [member Engine.time_scale]. The higher the time scale, the sooner timers will end. How often a timer processes may depend on the framerate or [member Engine.physics_ticks_per_second]. https://godotengine.org/asset-library/asset/515 Returns [code]true[/code] if the timer is stopped or has not started. Starts the timer, if it was not started already. Fails if the timer is not inside the tree. If [param time_sec] is greater than [code]0[/code], this value is used for the [member wait_time]. [b]Note:[/b] This method does not resume a paused timer. See [member paused]. Stops the timer. If [code]true[/code], the timer will start immediately when it enters the scene tree. [b]Note:[/b] After the timer enters the tree, this property is automatically set to [code]false[/code]. If [code]true[/code], the timer will stop after reaching the end. Otherwise, as by default, the timer will automatically restart. If [code]true[/code], the timer is paused. A paused timer does not process until this property is set back to [code]false[/code], even when [method start] is called. Specifies when the timer is updated during the main loop (see [enum TimerProcessCallback]). The timer's remaining time in seconds. This is always [code]0[/code] if the timer is stopped. [b]Note:[/b] This property is read-only and cannot be modified. It is based on [member wait_time]. The time required for the timer to end, in seconds. This property can also be set every time [method start] is called. [b]Note:[/b] Timers can only process once per physics or process frame (depending on the [member process_callback]). An unstable framerate may cause the timer to end inconsistently, which is especially noticeable if the wait time is lower than roughly [code]0.05[/code] seconds. For very short timers, it is recommended to write your own code instead of using a [Timer] node. Timers are also affected by [member Engine.time_scale]. Emitted when the timer reaches the end. Update the timer every physics process frame (see [constant Node.NOTIFICATION_INTERNAL_PHYSICS_PROCESS]). Update the timer every process (rendered) frame (see [constant Node.NOTIFICATION_INTERNAL_PROCESS]).
