補間動畫Pixel Bender過濾器使用數字值與Actionscript 3.0中的基本吐溫類

Question

我正在學習Pixel Bender。我有一個過濾器誰是參數我想補間。據我所知，爲了調出像素彎曲參數，我需要補間一個數字對象，並將補間數字對象指定爲着色器數據的數組值。

我相信下面的工作，但似乎Number類不具有價值的財產，所以我不知道該用什麼屬性設置彌補數量對象一個新補的時候：

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

var shader:Shader; 
var shaderFilter:ShaderFilter; 
var motionTween:Tween; 
var tweenNumber:Number = new Number(0.0); 
var loader:URLLoader = new URLLoader(); 

loader.dataFormat = URLLoaderDataFormat.BINARY; 
loader.addEventListener(Event.COMPLETE, dataLoaded); 
loader.load(new URLRequest("PBFilter.pbj")); 

function dataLoaded(e:Event):void 
    { 
    loader.removeEventListener(Event.COMPLETE, dataLoaded); 
    shader = new Shader(e.target.data); 
    shaderFilter = new ShaderFilter(shader); 
    flower.filters = [shaderFilter]; 

    motionTween = new Tween(tweenNumber, "value", Bounce.easeOut, 0.0, 100.0, 5, true); 
    motionTween.addEventListener(TweenEvent.MOTION_CHANGE, updateFilter); 
    } 

function updateFilter(e:TweenEvent):void 
    { 
    shader.data.amount.value = [tweenNumber]; 
    myMovieClip.filters = [shaderFilter]; 
    } 

Answer 1

也許你可以添加你補間一個getter和setter到您的測試類：

//... 
public function get amount():Number { 
return tweenNumber; 
} 
public function set amount(value:Number):void { 
tweenNumber=value; 
} 
//... 
motionTween = new Tween(this, "amount", Bounce.easeOut, 0.0, 100.0, 5, true); 
motionTween.addEventListener(TweenEvent.MOTION_CHANGE, updateFilter); 
//... 

- 或做更新到您的二傳手

//... 
public function get amount():Number { 
return tweenNumber; 
} 
public function set amount(value:Number):void { 
tweenNumber=value; 
shader.data.amount.value = [value]; 
myMovieClip.filters = [shaderFilter]; 
} 
//... 
motionTween = new Tween(this, "amount", Bounce.easeOut, 0.0, 100.0, 5, true); 
//...
