Interface encapsulating general easing functions

  • t is the current time (or position) of the tween. This can be seconds or frames, steps, seconds, ms, whatever as long as the unit is the same as is used for the total time.
  • b is the beginning value of the property.
  • c is the change between the beginning and destination value of the property.
  • d is the total time of the tween.
