Interpolates an abstract value and supplies it to a method called over time. [MethodTweener] is similar to a combination of [CallbackTweener] and [PropertyTweener]. It calls a method providing an interpolated value as a paramater. See [method Tween.tween_method] for more usage information. [b]Note:[/b] [method Tween.tween_method] is the only correct way to create [MethodTweener]. Any [MethodTweener] created manually will not function correctly. Sets the time in seconds after which the [MethodTweener] will start interpolating. By default there's no delay. Sets the type of used easing from [enum Tween.EaseType]. If not set, the default easing is used from the [Tween] that contains this Tweener. Sets the type of used transition from [enum Tween.TransitionType]. If not set, the default transition is used from the [Tween] that contains this Tweener.
