<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] Timers are affected by [member Engine.time_scale], a higher scale means quicker timeouts, and vice versa.
|
|
[b]Note:[/b] To create a one-shot timer without instantiating a node, use [method SceneTree.create_timer].

<method name="is_stopped" qualifiers="const">

Returns [code]true[/code] if the timer is stopped or has not started.

<method name="start">

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].

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.

<member name="paused" type="bool" setter="set_paused" getter="is_paused">
|

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.

<member name="process_callback" type="int" setter="set_timer_process_callback" getter="get_timer_process_callback" enum="Timer.TimerProcessCallback" default="1">
|

Specifies when the timer is updated during the main loop (see [enum TimerProcessCallback]).
|
|
</member>
|
|
<member name="time_left" type="float" setter="" getter="get_time_left">
|
|
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].
|
|
</member>
|
|
<member name="wait_time" type="float" setter="set_wait_time" getter="get_wait_time" default="1.0">
|
|
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].
