關(guān)于ActionScript 1.0、ActionScript 2.0、java的區(qū)別與聯(lián)系——基于一個(gè)實(shí)例的討論
問(wèn)題：創(chuàng)建兩個(gè)位置大小顏色各不同的可拖拽的矩形。
方法一：method1.fla //ActionScript 1.0
//Flash Player 6（含）以上
//ActionScript 1.0或ActionScript 2.0均可
createEmptyMovieClip ("rectangle1_mc", 1);
rectangle1_mc._x = 10;
rectangle1_mc._y = 10;
with (rectangle1_mc) {
beginFill (0xff0000, 100);
moveTo (0, 0);
lineTo (200, 0);
lineTo (200, 200);
lineTo (0, 200);
endFill ();
}
rectangle1_mc.onPress = startDrag;
rectangle1_mc.onRelease = rectangle1_mc.onReleaseOutside = stopDrag;
//
createEmptyMovieClip ("rectangle2_mc", 2);
rectangle2_mc._x = 50;
rectangle2_mc._y = 50;
with (rectangle2_mc) {
beginFill (0xffcc00, 100);
moveTo (0, 0);
lineTo (400, 0);
lineTo (400, 100);
lineTo (0, 100);
endFill ();
}
rectangle2_mc.onPress = startDrag;
rectangle2_mc.onRelease = rectangle2_mc.onReleaseOutside = stopDrag;
方法二：method2.fla //ActionScript 2.0
//Flash Player 6（含）以上
//必須為ActionScript 2.0var rect1:Rectangle = new Rectangle (this, 10, 10, 200, 200, 0xff0000, 1);
var rect2:Rectangle = new Rectangle (this, 50, 50, 400, 100, 0xffcc00, 2);
delete rect1;
delete rect2;
delete Rectangle;
此方法必須得有一個(gè)Rectangle.as與之同路徑。Rectangle.as內(nèi)容如下：
class Rectangle extends MovieClip {
private var rectangle_mc:MovieClip;
public function Rectangle (target:MovieClip, x:Number, y:Number, w:Number, h:Number, color:Number, depth:Number) {
rectangle_mc = target.createEmptyMovieClip ("rectangle_mc" + depth, depth);
rectangle_mc._x = x;
rectangle_mc._y = y;
with (rectangle_mc) {
beginFill (color, 100);
moveTo (0, 0);
lineTo (w, 0);
lineTo (w, h);
lineTo (0, h);
endFill ();
}
rectangle_mc.onPress = startDrag;
rectangle_mc.onRelease = rectangle_mc.onReleaseOutside = stopDrag;
}
}
方法三：method3.java //如果.java也可以直接編譯.swf的話
public class method3{
public static void main(String[] args){
Rectangle rect1 = new Rectangle (this, 10, 10, 200, 200, 0xff0000, 1);
Rectangle rect2 = new Rectangle (this, 50, 50, 400, 100, 0xffcc00, 2);
//這里就不需要手動(dòng)delete了，因?yàn)閖ava有垃圾回收器，它會(huì)自動(dòng)清除。
}
}
class Rectangle extends MovieClip {
private MovieClip rectangle_mc;
public Rectangle (MovieClip target, Double x, Double y, Double w, Double h, Double color, Double depth) {
rectangle_mc = target.createEmptyMovieClip ("rectangle_mc" + depth, depth);
rectangle_mc._x = x;
rectangle_mc._y = y;
with (rectangle_mc) {
beginFill (color, 100);
moveTo (0, 0);
lineTo (w, 0);
lineTo (w, h);
lineTo (0, h);
endFill ();
}
rectangle_mc.onPress = startDrag;
rectangle_mc.onRelease = rectangle_mc.onReleaseOutside = stopDrag;
}
}
通過(guò)比較不難發(fā)現(xiàn)，ActionScript 1.0最靈活、最簡(jiǎn)單、最容易理解。但重復(fù)類似的操作時(shí)也會(huì)最繁瑣。如果要畫1000個(gè)位置大小顏色各不同的矩形的話，不累死也會(huì)被笑死!
ActionScript 2.0則非常系統(tǒng)，單獨(dú)用Rectangle.as定義了一個(gè)矩形類，使用時(shí)new即可，爽!有點(diǎn)小小的遺憾的是有幾行delete，當(dāng)然你也可以不加，讓它永遠(yuǎn)霸占你的內(nèi)存。
再看看java，看完了又看，看完了再看，呵呵! 啥也不說(shuō)了，誰(shuí)老大肯定有人知道。
