Creating the custom preloader in AS3

Hi,

I am try to use the preloader component from Flash CS3. But it takes more size while creating the swf file. So i try to create the custom preloader class in AS3. Its very nice look and we can set the preloader bar style as gradient or normal style. In below i added the custom preloader class code. use this code and enjoy.

package util

{

import flash.geom.Matrix;

import flash.text.TextField;

import flash.display.Sprite;

import flash.display.Graphics;

import flash.display.GradientType;

import flash.display.SpreadMethod;

import flash.display.InterpolationMethod;

public class Preloader extends Sprite

{

private var _matrix:Matrix;

private var _loadBar:Sprite;

private var _progressBG:Sprite;

private var _barColor:Array;

private var _percLabel:TextField;

private var _controlUtil:ControlUtils;

private var _preloaderWidth:Number = 0;

private var _preloaderHeight:Number = 0;

private var _trackColor:uint = 0xFFFFFF;

public function set barColor(val:Array):void

{

if(_barColor != val)

_barColor = val;

}

public function Preloader(wid:Number,hgt:Number,trackColor:uint)

{

super();

_matrix = new Matrix();

_preloaderWidth = wid;

_preloaderHeight = hgt;

_trackColor = trackColor;

_controlUtil = new ControlUtils();

createBackground();

}

private function createBackground():void

{

_progressBG = new Sprite();

_progressBG.graphics.clear();

_progressBG.graphics.lineStyle(0x000000,2);

_progressBG.graphics.beginFill(_trackColor,1);

_progressBG.graphics.drawRect(0,0,_preloaderWidth,_preloaderHeight);

_progressBG.graphics.endFill();

addChild(_progressBG);

_loadBar = new Sprite();

_progressBG.addChild(_loadBar);

_percLabel = _controlUtil.createTextField(0x000000);

_progressBG.addChild(_percLabel);

_percLabel.x = (_preloaderWidth - _percLabel.width)/2;

this.width = _preloaderWidth;

this.height = _preloaderHeight;

}

public function setLoadProgress(loaded:Number,total:Number):Boolean

{

var _percent:Number = loaded/total;

var _val:Number = Math.round(_percent * 100);

if(_val <= 100)

{

_percLabel.text = _val+" %";

var _tempValue:Number = Math.round(_percent * _preloaderWidth);

_matrix.createGradientBox(_tempValue,_preloaderHeight,Math.PI/2,0,0);

var _ratios:Array = [0,255];

var _alphas:Array = [0.75,0.75];

var _colors:Array = [_barColor[0],_barColor[1]];

_loadBar.graphics.clear();

if(_barColor.length > 1)

_loadBar.graphics.beginGradientFill(GradientType.LINEAR,_colors,_alphas,_ratios,_matrix);

else

_loadBar.graphics.beginFill(_barColor[0],0.7);

_loadBar.graphics.drawRect(1,1,_tempValue-1,_preloaderHeight-1);

_loadBar.graphics.endFill();

if(_val == 100)

return true;

}

return false;

}

}

}
