Interface EasingFunction

public interface EasingFunction
EasingFunction is a representation of mathematical easing functions useful for things like animation. A few default implementations of easing functions are present.

  • Method Details

    • ease

      float ease(float value)
      Eases a value between 0 and 1. A value of 0 should return 0. A value of 1 should return 1.
      Parameters:
      value - the input value
      Returns:
      the eased value
