SceneTreeTimer

继承： RefCounted < Object

One-shot timer.

描述

A one-shot timer managed by the scene tree, which emits timeout on completion. See also 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:


    func some_function():
        print("Timer started.")
        await get_tree().create_timer(1.0).timeout
        print("Timer ended.")


    public async Task SomeFunction()
    {
        GD.Print("Timer started.");
        await ToSignal(GetTree().CreateTimer(1.0f), SceneTreeTimer.SignalName.Timeout);
        GD.Print("Timer ended.");
    }

The timer will be dereferenced after its time elapses. To preserve the timer, you can keep a reference to it. See RefCounted.

Note: The timer is processed after all of the nodes in the current frame, i.e. node's Node._process method would be called before the timer (or Node._physics_process if process_in_physics in SceneTree.create_timer has been set to true).
