* Tweens were changed from Node to RefCounted. New API is inspired by DOTween. * Tweens are created and managed by SceneTree, similar to SceneTreeTimer, which makes them ultra cheap to use a lot. * Animating with Tweens is done by creating sequences of Tweeners. You create them from code and they autostart by default (fire-and-forget). * There are 4 Tweeners that cover the former Tween functionality: PropertyTweener, IntervalTweener, CallbackTweener and MethodTweener. * The methods were simplified a lot. Long argument lists are replaced with chained calls on Tweens and Tweeners. * Tweeners by default execute in sequence, so it's easy to create complex chained animations. * You can bind a Tween to a node. Tween will be removed automatically when the bound node is freed.

[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. Example:
|
|
[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]. Example:
|
|
[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]

|
<method name="from_current">
|
|
<return type="PropertyTweener">
|
|
</return>
|
|
<description>
|
|
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()
|

<argument index="0" name="delay" type="float">

|

<description>
|
|
Sets the time in seconds after which the [PropertyTweener] will start interpolating. By default there's no delay.

<argument index="0" name="ease" type="int" enum="Tween.EaseType">

|
|
<description>
|
|
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.
