Argument name Type Description
tween Tween The tween instance

Returns: (bool) If the tween has been initialized


Returns true if a given tween is initted. A tween is considered initted, when all the variables and current values are captured from the target instance. The values for a tween are captured on the very first step that the tween is rendered. For example, if you create a tween with delay of 10, the tween will be initialized on the very first frame after the 10 seconds delay. tween_from tweens are initialized on the same frame that are created.

Normally, you don't use this value for anything. Only for advanced debug purposes.
