Interface Tween

All Superinterfaces:
Cloneable
All Known Implementing Classes:
AbstractTween, Action, BaseAction, BlendableAction, BlendAction, ClipAction
public interface Tween extends Cloneable
Represents some action that interpolates across input between 0 and some length value. (For example, movement, rotation, fading.) It's also possible to have zero length 'instant' tweens.

  • Method Summary

    Modifier and Type
    Method
    Description
    double
    getLength()
    Returns the length of the tween.
    boolean
    interpolate(double t)
    Sets the implementation specific interpolation to the specified 'tween' value as a value in the range from 0 to getLength().

  • Method Details

    • getLength

      double getLength()
      Returns the length of the tween. If 't' represents time in seconds then this is the notional time in seconds that the tween will run. Note: all the caveats are because tweens may be externally scaled in such a way that 't' no longer represents actual time.
      Returns:
      the duration (in de-scaled seconds)

    • interpolate

      boolean interpolate(double t)
      Sets the implementation specific interpolation to the specified 'tween' value as a value in the range from 0 to getLength(). If the value is greater or equal to getLength() then it is internally clamped and the method returns false. If 't' is still in the tween's range then this method returns true.
      Parameters:
      t - animation time (in de-scaled seconds)
      Returns:
      true if t>length(), otherwise false
