主要代碼：
//定義公共函數(shù)。。。
class ClipBoard extends Object {
static var $contents:Object;
static var $operation:String;
function ClipBoard() {
}
//定義當(dāng)選擇剪切時(shí)的效果。。。
public static function cut(obj) {
obj._alpha = 50;
$contents = obj;
$operation = "cut";
}
//定義復(fù)制函數(shù)。。。
public static function copy(obj) {
$contents = obj;
$operation = "copy";
}
//定義刪除函數(shù)。。。
public static function remove(obj) {
$contents = obj;
$operation = "remove";
$contents.removeMovieClip();
}
//定義順時(shí)針旋轉(zhuǎn)。。。
public static function rotation(obj) {
$contents = obj;
$operation = "rotation";
$contents._rotation = 45;
}
//定義逆時(shí)針旋轉(zhuǎn)。。。
public static function rotation2(obj) {
$contents = obj;
$operation = "rotation2";
$contents._rotation -= 45;
}
//定義移動(dòng)。。。
private static var xm:Number;
private static var ym:Number;
public static function movethis(obj) {
$contents = obj;
$operation = "movethis";
_root.onMouseDown = function() {
xm = _xmouse;
ym = _ymouse;
movethisit();
};
function movethisit() {
_root.onEnterFrame = function() {
$contents._x = (xm-$contents._x)/5;
$contents._y = (ym-$contents._y)/5;
if (Math.abs($contents._x-xm)<0.5) {
_root.onEnterFrame = undefined;
}
};
}
}
//定義刷新。。。
public static function refish() {
getURL("javascript:location.reload()");
}
//定義粘貼功能。。。
public static function paste() {
if ($operation == "cut") {
$contents._x = _root._xmouse;
$contents._y = _root._ymouse;
$contents._alpha = 100;
$contents = undefined;
$operation = "";
} else if ($operation == "copy") {
var newdepth = $contents._parent.getNextHighestDepth();
var newname = $contents._name newdepth;
$contents.duplicateMovieClip(newname, newdepth);
$contents._parent[newname]._x = _root._xmouse;
$contents._parent[newname]._y = _root._ymouse;
$contents._alpha = 100;
$contents._parent[newname]._alpha = 100;
} else if ($operation == "remove") {
var newdepth = $contents._parent.getNextHighestDepth();
var newname = $contents._name newdepth;
$contents.removeMovieClip("");
} else {
return;
}
}
public function isEmpty():Boolean {
if ($contents != undefined) {
return false;
} else {
return true;
}
}
public function handleMenuCommand(obj, item):Void {
switch (item.caption) {
case "剪切__X" :
cut(obj);
break;
case "復(fù)制__C" :
copy(obj);
break;
case "粘貼__P" :
paste();
break;
case "刪除__D" :
remove(obj);
break;
case "刷新_F5" :
refish();
break;
case "往右旋轉(zhuǎn)" :
rotation(obj);
break;
case "往左旋轉(zhuǎn)" :
rotation2(obj);
break;
case "移動(dòng)此球" :
movethis(obj);
break;
}
}
}
定義右鍵菜單：
_global.$clipboard = new ClipBoard();
function menuCallback(obj, menuObj) {
var empty:Boolean = _global.$clipboard.isEmpty();
menuObj.customItems = [];
// 如果對象為影片剪輯，而不是 _root
if ((obj instanceof MovieClip) && (obj != _level0)) {
menuObj.customItems.push(cutItem);
menuObj.customItems.push(copyItem);
menuObj.customItems.push(remove);
menuObj.customItems.push(refish);
menuObj.customItems.push(rotation);
menuObj.customItems.push(rotation2);
menuObj.customItems.push(movethis);
if (!empty) {
menuObj.customItems.push(pasteItem);
menuObj.customItems.push(refish);
}
} else if (obj == _level0 && !empty) {
menuObj.customItems.push(pasteItem);
menuObj.customItems.push(refish);
}
}
var myMenu = new ContextMenu(menuCallback);
myMenu.hideBuiltInItems();
var cutItem = new ContextMenuItem("剪切__X", _global.$clipboard.handleMenuCommand);
var copyItem = new ContextMenuItem("復(fù)制__C", _global.$clipboard.handleMenuCommand);
var pasteItem = new ContextMenuItem("粘貼__P", _global.$clipboard.handleMenuCommand);
var remove = new ContextMenuItem("刪除__D", _global.$clipboard.handleMenuCommand);
var refish = new ContextMenuItem("刷新_F5", _global.$clipboard.handleMenuCommand);
var rotation = new ContextMenuItem("往右旋轉(zhuǎn)", _global.$clipboard.handleMenuCommand);
var rotation2 = new ContextMenuItem("往左旋轉(zhuǎn)", _global.$clipboard.handleMenuCommand);
var movethis = new ContextMenuItem("移動(dòng)此球", _global.$clipboard.handleMenuCommand);
MovieClip.prototype.menu = myMenu;
this.menu = myMenu;
stop();
使用方法很簡單，直接將制作好的MC拖入場景，然后在MC中加入如下代碼：
on (release) {
stopDrag();
//結(jié)束行為
}
on (press) {
startDrag(this);
//結(jié)束行為
mx.behaviors.DepthControl.bringToFront(this);
//結(jié)束行為
}
注意下載的“ClipBoard.as”類文件，要放在SWF同級目錄下。。。
