Flash AS教程:复制粘贴类

源码下载：flash_copy.rar
主要代码：

//定义公共函数。。。
class clipboard extends object {
static var $contents:object;
static var $operation:string;
function clipboard() {
}
//定义当选择剪切时的效果。。。
public static function cut(obj) {
obj._alpha = 50;
$contents = obj;
$operation = "cut";
}
//定义复制函数。。。
public static function copy(obj) {
$contents = obj;
$operation = "copy";
}
//定义删除函数。。。
public static function remove(obj) {
$contents = obj;
$operation = "remove";
$contents.removemovieclip();
}
//定义顺时针旋转。。。
public static function rotation(obj) {
$contents = obj;
$operation = "rotation";
$contents._rotation = 45;
}
//定义逆时针旋转。。。
public static function rotation2(obj) {
$contents = obj;
$operation = "rotation2";
$contents._rotation -= 45;
}
//定义移动。。。
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($contents._x-xm)<0.5) {
_root.onenterframe = undefined;
}
};
}
}
//定义刷新。。。
public static function refish() {
geturl("javascript:location.reload()");
}
//定义粘贴功能。。。
public static function paste() {
if ($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 "复制__c" :
copy(obj);
break;
case "粘贴__p" :
paste();
break;
case "删除__d" :
remove(obj);
break;
case "刷新_f5" :
refish();
break;
case "往右旋转" :
rotation(obj);
break;
case "往左旋转" :
rotation2(obj);
break;
case "移动此球" :
movethis(obj);
break;
}
}
}

定义右键菜单：
_global.$clipboard = new clipboard();
function menucallback(obj, menuobj) {
var empty:boolean = _global.$clipboard.isempty();
menuobj.customitems = [];
// 如果对象为影片剪辑，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.$clipboard.handlemenucommand);
var copyitem = new contextmenuitem("复制__c", _global.$clipboard.handlemenucommand);
var pasteitem = new contextmenuitem("粘贴__p", _global.$clipboard.handlemenucommand);
var remove = new contextmenuitem("删除__d", _global.$clipboard.handlemenucommand);
var refish = new contextmenuitem("刷新_f5", _global.$clipboard.handlemenucommand);
var rotation = new contextmenuitem("往右旋转", _global.$clipboard.handlemenucommand);
var rotation2 = new contextmenuitem("往左旋转", _global.$clipboard.handlemenucommand);
var movethis = new contextmenuitem("移动此球", _global.$clipboard.handlemenucommand);
movieclip.prototype.menu = mymenu;
this.menu = mymenu;
stop();
使用方法很简单，直接将制作好的mc拖入场景，然后在mc中加入如下代码：
on (release) {
stopdrag();
//结束行为
}
on (press) {
startdrag(this);
//结束行为
mx.behaviors.depthcontrol.bringtofront(this);
//结束行为
}
注意下载的“clipboard.as”类文件，要放在swf同级目录下。。。
