flash背包系统，就是物品能拖拽，物品数量的变量随之而转移的。

购物，出售物品，使用物品，装备物品，那是一个比较大的块儿，下面代码给你参照呗。

我要用flash做个背包系统~~~~~~

那你写吧。你不会让别人给你做好吧。

4*5就是20个MC了。把xml读出来。内容存入数组。
然后把数组的内容显示在你指定的MC。就可以了。

呵呵
首先 你先把这36张照片做到一个影片剪辑元件中，该元件第一帧停止

然后把这个元件拖到舞台上，命名为mc

然后在第一帧加入如下代码

var speed:Number=0.1;//速度参数，修改次参数可以调整速度
var long:int=mc.totalFrames;//总帧数
var newX:Number;
var frame:Number=mc.currentFrame;//当前是第几帧
stage.addEventListener(MouseEvent.MOUSE_DOWN,mdown);
stage.addEventListener(MouseEvent.MOUSE_UP,mup);
function mdown(e:MouseEvent):void {
newX=e.stageX;
stage.addEventListener(MouseEvent.MOUSE_MOVE,mmove);
}
function mup(e:MouseEvent):void {
stage.removeEventListener(MouseEvent.MOUSE_MOVE,mmove);
}
function mmove(e:MouseEvent):void {
if ((frame+(e.stageX-newX)*speed)>=1) {
frame=((frame+(e.stageX-newX)*speed)-1)%long+1;
} else if ((frame+(e.stageX-newX)*speed)>0) {
frame=long+frame+(e.stageX-newX)*speed;
} else {
frame=long-Math.abs(frame+(e.stageX-newX)*speed)%long;
}
newX=e.stageX;
mc.gotoAndStop(int(frame));
}

这个是AS3的代码 如果是AS2的话再补充，如果元件的实例名不方便为mc的话，可以改成别的，不过代码中的所有mc都要替换成新的名称

其实像做这种3D的东西，如果楼主代码基础好的话，可以参考下PV3D的资料，功能非常强大！

我不是复制，这个是我自己的答案！

(15717604118)： 正常现象,关闭网页重新进入,不行重启电脑,还不行就修复FLASH,可能版本低了

(15717604118)： flash 里面都自带有脚本助手的.只是只有当你写入了关键词时,脚本助手才会激活,才能帮你写脚本,这脚本助手只是帮助修改脚本是比较方便,而还不适用于自己编写脚本,如果自己编写的话,还是情愿用flash的代码提示,而更加快捷,也可以加深自己对脚本的编写,
