推薦：Flash入門實(shí)例鼠繪教程:風(fēng)車在卡通風(fēng)景畫中的畫法
簡(jiǎn)介：本例為Flash鼠繪新手入門實(shí)例系列課程，今天我們來(lái)學(xué)習(xí)在Flash中繪制美麗卡通風(fēng)景畫中的風(fēng)車，適合新手朋友學(xué)習(xí)，感興趣的朋友可以到論壇提交作業(yè)～～ “Flash動(dòng)畫鼠繪入門班”實(shí)例課教

效果演示：（請(qǐng)用鼠標(biāo)在畫面上點(diǎn)擊觀看效果）

在這個(gè)教程中，我們將添加模糊和斜角濾鏡給圖片。所有的動(dòng)畫都是用 Actionscript 3.0制作。在圖片上移動(dòng)你的鼠標(biāo)看看效果。當(dāng)你掌握了這些你將同樣能創(chuàng)建另一些濾鏡效果。好吧，打開你的flash我們開始吧。

設(shè)置環(huán)境

1. 創(chuàng)建一個(gè)新的文檔，大小為500x250
2. 導(dǎo)入兩張圖片到舞臺(tái)（大約200x200）。你可以象我一樣導(dǎo)入一張方的和一張園的圖片。
3. 將兩張圖片轉(zhuǎn)換為MC，你可以這它們?nèi)∩夏阆矚g的名字；將注冊(cè)點(diǎn)移到中心。
4. 給它們?nèi)∩蠈?shí)例名稱分別為：“apple01”和“apple02”

進(jìn)入AS3打開你的動(dòng)作面板輸入下面的代碼：
//使用動(dòng)畫濾鏡
var blurSpeed:Number = 1;
var bevelSpeed:Number = 5;
//為兩個(gè)蘋果添加MOUSE_OVER 事件偵聽
appleapple01.addEventListener(MouseEvent.MOUSE_OVER,mouseOverApple01);
apple02.addEventListener (MouseEvent.MOUSE_OVER, mouseOverApple02);
//這兩個(gè)蘋果添加MOUSE_OUT 事件偵聽
appleapple01.addEventListener(MouseEvent.MOUSE_OUT,mouseOutApple01);
apple02.addEventListener (MouseEvent.MOUSE_OUT, mouseOutApple02);
/*為兩個(gè)蘋果添加ENTER_FRAME，這樣我們就能每隔一幀的時(shí)間繪制它們*/
apple01.addEventListener(Event.ENTER_FRAME,enterFrameApple01);
apple02.addEventListener (Event.ENTER_FRAME, enterFrameApple02);
//創(chuàng)建并附加模糊濾鏡給apple01
var blur:BlurFilter = new BlurFilter();
blur.blurX = 20;
blur.blurY = 20;
blur.quality = BitmapFilterQuality.HIGH;
apple01.filters = [blur];
//創(chuàng)建一個(gè)斜角濾鏡給apple02
var bevelFilter:BevelFilter=new BevelFilter(10, 45,0x000000,1, 0xffffff,1,0, 0, 0, BitmapFilterQuality.HIGH,BitmapFilterType.INNER,false);
apple02.filters = [bevelFilter];
//設(shè)置省缺值（鼠標(biāo)沒移動(dòng)到蘋果上時(shí)）
var mouseIsOverApple01:Boolean = false;
var mouseIsOverApple02:Boolean = false;
//當(dāng)鼠標(biāo)移到apple01上時(shí)調(diào)用
function mouseOverApple01 (event:MouseEvent):void {
mouseIsOverApple01 = true;
}
//當(dāng)鼠標(biāo)移到apple02上時(shí)調(diào)用
function mouseOverApple02 (event:MouseEvent):void {
mouseIsOverApple02 = true;
}
//當(dāng)鼠標(biāo)移出apple01 時(shí)調(diào)用
function mouseOutApple01 (event:MouseEvent):void {
mouseIsOverApple01 = false;
}
//當(dāng)鼠標(biāo)移出apple02 時(shí)調(diào)用
function mouseOutApple02 (event:MouseEvent):void {
mouseIsOverApple02 = false;
}
//這個(gè)函數(shù)繪制apple01 的動(dòng)畫
function enterFrameApple01 (event:Event):void {
//如果鼠標(biāo)在蘋果上移動(dòng)減少模糊
if (mouseIsOverApple01 == true) {
blur.blurX -= blurSpeed;
blur.blurY -= blurSpeed;
}
/* 如果鼠標(biāo)移出蘋果,并且模糊沒超過(guò)20，我們?cè)黾幽：��?/
if (mouseIsOverApple01 == false && blur.blurX <= 20) {
blur.blurX = blurSpeed;
blur.blurY = blurSpeed;
}
/*在改變模糊濾鏡后我需要重新分配濾鏡*/
apple01.filters = [blur];
}
//這個(gè)函數(shù)繪制apple02的動(dòng)畫
function enterFrameApple02 (event:Event):void {
//如果鼠標(biāo)移到這個(gè)蘋果上，我們?cè)黾幽：秊V鏡直到100
if (mouseIsOverApple02 == true && bevelFilter.blurX < 100) {
bevelFilter.blurX = bevelSpeed;
bevelFilter.blurY = bevelSpeed;
//我們需要分配一個(gè)力度給斜角讓它可見
bevelFilter.strength = 5;
}
//如果鼠標(biāo)移出apple02, 減少模糊
if (mouseIsOverApple02 == false) {
bevelFilter.blurX -= bevelSpeed;
bevelFilter.blurY -= bevelSpeed;
}
/*如果我們確定模糊濾鏡正被使用，我們讓整個(gè)斜角不可見。(strength is 0).否則我們會(huì)看到一些難看的曲線。*/
if(bevelFilter.blurX == 0) {
bevelFilter.strength = 0;
}
/*當(dāng)我們改變了斜角濾鏡時(shí)，我們需要重新分配一次濾鏡*/
apple02.filters = [bevelFilter];
}
