Packagefl.motion.easing
Classpublic class Quadratic

The Quadratic class defines three easing functions to implement accelerated motion with ActionScript animations. The acceleration of motion for a Quadratic easing equation is the same as for a timeline tween at 100% easing and is less dramatic than for the Cubic easing equation.

 MethodDefined by
  
easeIn(t:Number, b:Number, c:Number, d:Number):Number
[static] The easeIn() method starts motion from a zero velocity and then accelerates motion as it executes.
Quadratic
  
easeInOut(t:Number, b:Number, c:Number, d:Number):Number
[static] The easeInOut() method combines the motion of the easeIn() and easeOut() methods to start the motion from a zero velocity, accelerate motion, then decelerate to a zero velocity.
Quadratic
  
easeOut(t:Number, b:Number, c:Number, d:Number):Number
[static] The easeOut() method starts motion fast and then decelerates motion to a zero velocity as it executes.

Method detail
easeIn()method
public static function easeIn(t:Number, b:Number, c:Number, d:Number):Number

The easeIn() method starts motion from a zero velocity and then accelerates motion as it executes.

Parameters
t:Number — Specifies the current time, between 0 and duration inclusive.
 
b:Number — Specifies the initial value of the animation property.
 
c:Number — Specifies the total change in the animation property.
 
d:Number — Specifies the duration of the motion.

Returns
Number — The value of the interpolated property at the specified time.
