플래시 as3 페이드 인 fadeout xml 슬라이드 쇼

Question

나는 as3.0을 (를) 처음 사용하고 있기 때문에 프로젝트를 완료하고 싶습니다.

내 XML 슬라이드 쇼에 아래 코드를 사용하고 있지만 사진이 희미 해져서 흰색으로 변하지 않아야합니다. 어떤 전문가가 나를 도울 수 있기를 바랍니다.

좋아, 먼저 페이드 인하려는 이미지에 대한 변수를 만들어야합니다. 어느 것이 더 명확하게 정리해 보겠습니다. 이전과 동일한 방식으로 제 화상 (현재 theCurrentImage)에

var theCurrentImage:DisplayObject; 
var theNextImage:DisplayObject; 

로드.

지금 여기에 당신이 배열에 다음 이미지를로드 할 수 방법은 다음과 같습니다

function loadNextImage():void { 
    currPainting++; 
    // you should also make sure currPainting is not out of bounds here 
    loadImage(); 
} 

function loadImage():void { 
    imageLoader = new Loader(); 
    imageLoader.addEventListener(Event.COMPLETE, onImageLoaded); 
    // other listeners go here too 
    imageLoader.load(new URLRequest(imageArray[currPainting])); 
} 

function onImageLoaded(e:Event):void { 
    theNextImage = imageLoader; // stores the next image ready to be faded in 
    theNextImage.alpha = 0; 
    addChild(theNextImage); // now ready to be cross-faded in 
    crossFade(); 
} 

function crossFade():void { 
    TweenLite.to(theCurrentImage, 1, {alpha:0}); 
    TweenLite.to(theNextImage, 1, {alpha:1}); 
    // remove theCurrentImage (now invisible) from the stage 
    removeChild(theCurrentImage); 
    // theNextImage is now the displayed image so... 
    theCurrentImage = theNextImage; 
    theNextImage = null; 
    // ready to load the next image by calling loadNextImage() 
}
