Question

flash一段as2.0代码转成as3.0的要怎么写啊

var sceneWidth = 1920;

var sceneHeight = 1080;

var starNum = 1000;

var starSpeed = 50;

var starTime = 100;

var starDistance = true;

this.starMc._visible = 0;

for (var i = 0; i<starNum; i++) {
mc = this.starMc.duplicateMovieClip("startMc"+i, i+999);
mc.gotoAndPlay(random(mc._totalframes+1));
mc._x = random(sceneWidth);
mc._y = random(sceneHeight);
mc._xscale = mc._yscale=mc._alpha=random(50)+50;
mc._rotation = random(360);
mc.onEnterFrame = function() {
if (starDistance == true) {
if (this._x>0) {
this._x -= starSpeed/this._xscale;
} else {
this._x = sceneWidth;
}
} else {
if (this._x<sceneWidth) {
this._x += starSpeed/this._xscale;
} else {
this._x = 0;
}
}
}
}

Answer 1

你需要改动一下，将库中的元件的类名称（链接属性）写上，然后才能修改脚本，而且必须保存为AS3.0的才可以修改脚本。不过你的分太少了，增加分吧。

应该主要是这段。。其他的属性只要把前面的_去掉就可以
for (var i = 0; i<starNum; i++) {
mc = this.starMc.duplicateMovieClip("startMc"+i, i+999);//var mc=new startMc();//这个startMc应该为库里该元件的链接名称
mc.gotoAndPlay(random(mc._totalframes+1));//mc.gotoAndPlay(random(mc._totalframes+1));
mc._x = random(sceneWidth);//改为x，random要用Math.random()*sceneWidth
mc._y = random(sceneHeight);//改为y,random同上
mc._xscale = mc._yscale=mc._alpha=random(50)+50;//改属性写法和random
mc._rotation = random(360);
mc.onEnterFrame = function() {//此处函数不可这么写。应该用侦听。。mc.addEventListener(Event.ENTER_FRAME,enterFrame),把下面的函数放在enterFrame里面。。}
}
function enterFrame(e:Event){
if (starDistance == true) {
if (this._x>0) {//this改为e.target
this._x -= starSpeed/this._xscale;
} else {
this._x = sceneWidth;
}
} else {
if (this._x<sceneWidth) {
this._x += starSpeed/this._xscale;
} else {
this._x = 0;
}
}

}
主要是这么几点。

追问

还是不行啊
