Question

您好我想在我的as3上实现一个简单的按钮。但这不起作用。

我刚刚将bouton1添加到我的场景中，但当我点击它时没有任何反应（跟踪功能不会显示我的消息

这是我的代码

你知道为什么我的踪迹（“测试”），不起作用吗？

与对象拖动存在冲突吗？

flash不显示错误

SimpleButton对象比“添加并忘记”更复杂，您需要填充其属性，这通常在设计时完成。有四个DisplayObject类型对象，即upState, overState, downState, hitTestState，用于确定该按钮的形状和内容。为了使按钮可见且可命中，您需要指定4个Sprite（或其他DisplayObject）作为SimpleButton构造函数的参数。 hitTestState对象用于捕获事件，并且始终不可见，因此您只需要在其上绘制正确的形状。当按钮启动，鼠标悬停在按钮上以及按钮上分别按下鼠标时，其他状态可见。

var upSprite:Sprite=new Sprite();
upSprite.graphics.lineStyle(2,0,1);
upSprite.graphics.drawRect(0,0,50,20);
var hitSprite:Shape=new Shape();
hitSprite.graphics.beginFill(0,1);
hitSprite.graphics.drawRect(3,3,44,14); // a bit smaller rect to make the button narrow
var bouton1:SimpleButton=new SimpleButton(upSprite,upSprite,upSprite,hitSprite);

Answer 2

尝试在mouse_down上执行跟踪操作，而不是单击。
您在最后一行中提到了if（isMouseDown）。如果这是错的，我很抱歉，但是你要说if if（isMouseDown）= true
