Regular

Package	fl.transitions.easing
Class	public class Regular
Inheritance	Regular Object

Language Version:

ActionScript 3.0

Product Version:

Flash CS3

Runtime Versions:

Flash Player 9.0, AIR 1.0

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

Method Detail

easeIn

()

method

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

Language Version:

ActionScript 3.0

Product Version:

Flash CS3

Runtime Versions:

Flash Player 9.0, AIR 1.0

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.

Example ( How to use this example )

This example animates a rectangle using the Regular.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", Regular.easeIn, startValue, finishValue, duration, true);
myTween.looping = true;

easeInOut

()

method

public static function easeInOut(t:Number, b:Number, c:Number, d:Number):Number

Language Version:

ActionScript 3.0

Product Version:

Flash CS3

Runtime Versions:

Flash Player 9.0, AIR 1.0

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.

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.

The easeOut() method starts motion fast and then decelerates motion to a zero velocity 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.
