Description
-----------

A one-shot timer managed by the scene tree, which emits :ref:`timeout<class_SceneTreeTimer_signal_timeout>` on completion. See also :ref:`SceneTree.create_timer<class_SceneTree_method_create_timer>`.

As opposed to :ref:`Timer<class_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("start")
    yield(get_tree().create_timer(1.0), "timeout")
    print("end")
