Interpolates an [Object]'s property over time. [PropertyTweener] is used to interpolate a property in an object. See [method Tween.tween_property] for more usage information. [b]Note:[/b] [method Tween.tween_property] is the only correct way to create [PropertyTweener]. Any [PropertyTweener] created manually will not function correctly. When called, the final value will be used as a relative value instead. [b]Example:[/b] [codeblock] var tween = get_tree().create_tween() tween.tween_property(self, "position", Vector2.RIGHT * 100, 1).as_relative() #the node will move by 100 pixels to the right [/codeblock] Sets a custom initial value to the [PropertyTweener]. [b]Example:[/b] [codeblock] var tween = get_tree().create_tween() tween.tween_property(self, "position", Vector2(200, 100), 1).from(Vector2(100, 100)) #this will move the node from position (100, 100) to (200, 100) [/codeblock] Makes the [PropertyTweener] use the current property value (i.e. at the time of creating this [PropertyTweener]) as a starting point. This is equivalent of using [method from] with the current value. These two calls will do the same: [codeblock] tween.tween_property(self, "position", Vector2(200, 100), 1).from(position) tween.tween_property(self, "position", Vector2(200, 100), 1).from_current() [/codeblock] Allows interpolating the value with a custom easing function. The provided [param interpolator_method] will be called with a value ranging from [code]0.0[/code] to [code]1.0[/code] and is expected to return a value within the same range (values outside the range can be used for overshoot). The return value of the method is then used for interpolation between initial and final value. Note that the parameter passed to the method is still subject to the tweener's own easing. [b]Example:[/b] [codeblock] @export var curve: Curve func _ready(): var tween = create_tween() # Interpolate the value using a custom curve. tween.tween_property(self, "position:x", 300, 1).as_relative().set_custom_interpolator(tween_curve) func tween_curve(v): return curve.sample_baked(v) [/codeblock] Sets the time in seconds after which the [PropertyTweener] 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.
