我是Actionscript的新手，所以我不确定我的代码存在什么问题。
我正在创建一个Flash / Actionscript游戏，孩子们可以将不同的食物拖放到食物金字塔上 - 现代食物。拖放所有项目，但只有第一项（banana_mc）创建反馈。我不知道为什么会这样，并且没有编译器错误。
我的动作如下：
banana_mc.objName = "banana";
banana_mc.initX = banana_mc.x;
banana_mc.initY = banana_mc.y;
banana_mc.val = 0;
bread_mc.objName = "bread";
bread_mc.initX = bread_mc.x;
bread_mc.initY = bread_mc.y;
bread_mc.val = 0;

broccoli_mc.val = 0;

burger_mc.val = 0;

carrot_mc.val = 0;
cheese_mc.objName = "cheese";
cheese_mc.initX = cheese_mc.x;
cheese_mc.initY = cheese_mc.y;
cheese_mc.val = 0;
chips_mc.objName = "chips";
chips_mc.initX = chips_mc.x;
chips_mc.initY = chips_mc.y;
chips_mc.val = 0;
corn_mc.objName = "corn";
corn_mc.initX = corn_mc.x;

eggplant_mc.initX = eggplant_mc.x;
eggplant_mc.initY = eggplant_mc.y;
eggplant_mc.val = 0;

如果有人能帮助我，我真的很感激！它本周是作业的一部分（不是编码），所以如果可能我真的需要一个快速的解决方案......

您的switch语句配置为查找对象名称指定的确切字符串。套管问题:) 要么使用item.objName.toLocalLowercase（），要将对象的名称更改为仅包含小写字母，要么更改您的大小写以匹配除了banana之外的所有对象的所有对象的名称。

减少代码量只是一个有用的提示...
在你底部的function updateShape(item:MovieClip, bin:MovieClip):void，你有：
resetShapes();可能会更好resetShapes( item );
如果你提供一个函数参数（ aka 函数参数），那么当你运行resetShapes时，它只需要处理当前点击的项目（作为函数参数提供），这样你就可以只是简单地写...
function resetShapes ( in_item : MovieClip ) : void
{
if( in_item.val == 1)
{
in_item.x = in_item.initX;
in_item.visible = true;
in_item.val = 0;
}
}
同样在您的function mouseRelease(event:MouseEvent):void底部，default : ; ;这可能会在您尝试编译时导致问题，因此修复或删除它。你想用这个命令做什么？如果我们理解您的代码或逻辑，那么给您的建议会更容易。
