向按鈕添加事件監聽器

Question

我是Actionscript的新手，我正在創建一個簡單的添加遊戲，玩家將點擊屏幕底部的數字1至9來解決附加問題。我應該在底部創建單獨的按鈕還是動畫片段？

如何添加事件偵聽器到按鈕/動畫片段，以便能夠判斷玩家是否點擊了第二個按鈕而不是屏幕上的其他按鈕。謝謝！

非常相似羅尼的解決方案（我幾乎完成了這個所以不得不發佈），並且測試：

import flash.display.MovieClip; 
import flash.text.TextField; 
import flash.text.TextFieldAutoSize; 
import flash.events.MouseEvent; 
import flash.text.TextFormat; 

var buttonCount = 9; 
var buttonSize = 50; 

var button:MovieClip; 
var label:TextField; 

for (var i:int = 0; i < buttonCount; i ++) 
{ 
    // Create a new MovieClip 
    button = new MovieClip(); 

    // We'll use this in the event handler to identify which button was clicked 
    button.id = i + 1; 

    // Draw the background in the graphics prop of the MovieClip 
    button.graphics.beginFill(0x00ff00, 1); 
    button.graphics.drawRect(0, 0, buttonSize, buttonSize); 

    // Add event listener 
    button.addEventListener(MouseEvent.CLICK, this.clickHandler); 

    // Position the button 
    button.x = i * (buttonSize + 20); // Add some spacing 
    button.y = stage.stageHeight - buttonSize - 10; 

    // Add the button to the stage 
    addChild(button); 

    // Create the label for the button 
    label = new TextField(); 
    label.text = button.id.toString(); 
    label.selectable = false; 
    label.multiline = false; 
    label.autoSize = TextFieldAutoSize.LEFT; 
    label.setTextFormat(new TextFormat('Arial', 12, 0, true)); 

    // Position the label in the centre of the button 
    label.x = (buttonSize - label.width)/2; 
    label.y = (buttonSize - label.height)/2; 

    // Add the label to the button MovieClip 
    button.addChild(label); 
} 

function clickHandler(event:MouseEvent):void 
{ 
    trace("Button clicked:", event.currentTarget.id); 
}

我會做的是讓在它的文本字段一個影片剪輯。例如，我有一個影片剪輯（連接名稱爲NumClip）和一個名爲（確保嵌入數字或任何其他需要的字符）的動態文本字段。然後一個簡單的循環應該做的伎倆。

var maxNum:Number = 9; 

for (var i:int = 1; i <= maxNum; i++) 
{ 
    var clip:NumClip = new NumClip(); 
    clip.x = i * (clip.width + 5); 
    clip.y = 50; 
    clip.id = i; 
    clip.numText.text = String(i); 
    clip.addEventListener(MouseEvent.CLICK, numClick); 
    addChild(clip); 
} 

function numClick(e:MouseEvent):void 
{ 
    trace("You clicked number " + e.currentTarget.id); 
} 

我沒有測試此代碼，但它看起來不錯，我和應該做的伎倆
