fl.transitions.easing.None - ActionScript® 3.0 Reference for the Adobe® Flash® Platform

Package	fl.transitions.easing
Class	public class None
Inheritance	None Object

Language Version:

ActionScript 3.0

Product Version:

Flash CS3

Runtime Versions:

Flash Player 9.0, AIR 1.0

The None class defines easing functions to implement nonaccelerated motion with ActionScript animations. Its methods all produce the same effect, a constant motion. The various names, easeIn, easeOut and so on are provided in the interest of polymorphism. The None class is identical to the fl.motion.easing.Linear class in functionality.

The easeIn() method defines a constant motion, with no acceleration.

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.

This example animates a rectangle using the None.easeIn easing function:

import fl.transitions.*;
import fl.transitions.easing.*;

stage.frameRate = 31;

var box:Sprite = new Sprite();
box.graphics.beginFill(Math.random() * 0xFFFFFF);
box.graphics.drawRect(0, 0, 100, 350);
box.graphics.endFill();
box.x = 50;
box.y = 10;
addChild(box);

var startValue:Number = box.x;
var finishValue:Number = 400;
var duration:Number = 3;
var myTween:Tween = new Tween(box, "x", None.easeIn, startValue, finishValue, duration, true);
