关于AS1.0、AS2.0和java

问题：创建两个位置大小颜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

//必须为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;

此方法必须得有一个Rectangle.as与之同路径。Rectangle.as内容如下：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也可以直接编译.swf的话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);

//这里就不需要手动delete了，因为java有垃圾回收器，它会自动清除。

}

}

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;

}

}

通过比较不难发现，ActionScript 1.0最灵活、最简单、最容易理解。但重复类似的操作时也会最繁琐。如果要画1000个位置大小颜色各不同的矩形的话，不累死也会被笑死! ActionScript 2.0则非常系统，单独用Rectangle.as定义了一个矩形类，使用时new即可，爽!有点小小的遗憾的是有几行delete，当然你也可以不加，让它永远霸占你的内存。再看看java，看完了又看，看完了再看，呵呵! 啥也不说了，谁老大肯定有人知道。
