One-shot timer. A one-shot timer managed by the scene tree, which emits [signal timeout] on completion. See also [method SceneTree.create_timer]. As opposed to [Timer], it does not require the instantiation of a node. Commonly used to create a one-shot delay timer as in the following example: [codeblock] func some_function(): print("Timer started.") yield(get_tree().create_timer(1.0), "timeout") print("Timer ended.") [/codeblock] The timer will be automatically freed after its time elapses. The time remaining (in seconds). Emitted when the timer reaches 0.
