easeIn(t:Number, b:Number, c:Number, d:Number, s:Number = 0):Number
[static] The easeIn() method starts the motion by backtracking and then reversing direction and moving toward the target.

easeInOut(t:Number, b:Number, c:Number, d:Number, s:Number = 0):Number
[static] The easeInOut() method combines the motion of the easeIn() and easeOut() methods to start the motion by backtracking, then reversing direction and moving toward the target, overshooting the target slightly, reversing direction again, and then moving back toward the target.

Runtime Versions : Flash Player 9.0, AIR 1.0

The easeIn() method starts the motion by backtracking and then reversing direction and moving toward the target.

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.
 
s:Number (default = 0) — Specifies the amount of overshoot, where the higher the value, the greater the overshoot.

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