刪除不同級別的孩子As3

我已經在舞臺上添加了許多對象（在Achievements.as類中）來創建成就板。當有人按下後退按鈕時，我想從main.as類中刪除所有的孩子。另外，有沒有辦法創建一個自定義textField類，其中每個textField.selectable = false，而不必分別分配給每個。刪除不同級別的孩子As3

public static var texts:Vector.<TextField> = new Vector.<TextField>(); 
public static var titleTxt:Vector.<TextField> = new Vector.<TextField>(); 
public static var descripTxt:Vector.<TextField> = new Vector.<TextField>(); 
public static var rewardTxt:Vector.<TextField> = new Vector.<TextField>(); 
public static var achCoins:Vector.<MovieClip> = new Vector.<MovieClip>(); 

for (var j:int = 0; j < 30; j++) 
     { 
      achCoins[j].x = 240; 
      achCoins[j].y = 45 + j * 70; 
      addChild(achCoins[j]); 
      descripTxt[j].x = 0; 
      descripTxt[j].y = 30 + 70 * j; 
      //descripTxt[j].antiAliasType = AntiAliasType.ADVANCED; 
      descripTxt[j].defaultTextFormat = tf2; 
      descripTxt[j].text = descriptext[j]; 
      descripTxt[j].embedFonts = true; 
      addChild(descripTxt[j]); 
      titleTxt[j].x = 0; 
      titleTxt[j].y = j * 70; 
      //titleTxt[j].antiAliasType = AntiAliasType.ADVANCED; 
      titleTxt[j].defaultTextFormat = tf3; 
      titleTxt[j].text = titletext[j]; 
      titleTxt[j].embedFonts = true; 
      addChild(titleTxt[j]); 
      rewardTxt[j].x = 200; 
      rewardTxt[j].y = 30 + j * 70; 
      rewardTxt[j].text = reward[j].toString(); 
      rewardTxt[j].setTextFormat(tf1); 
      rewardTxt[j].embedFonts = true; 
      rewardTxt[j].textColor = 0x000000; 
      addChild(rewardTxt[j]); 
      texts[j].text = Main.achievement[j] + "/" + totnum[j]; 
      texts[j].setTextFormat(tf1); 
      texts[j].x = 200; 
      texts[j].y = j * 70; 
      texts[j].embedFonts = true; 
      addChild(texts[j]); 

     }

然後我使用此代碼

for (var k:int = 0; k < 30; k++) 
     { 
      removeChild(achievementback.descripTxt[k]); 
      removeChild(achievementback.titleTxt[k]); 
      removeChild(achievementback.rewardTxt[k]); 
      removeChild(achievementback.texts[k]); 

     }

我得到的錯誤

1119: Access of possibly undefined property descripTxt through a reference with static type Achievements.

for (var i:int = 0; i < 30; i++) 
     { 
      texts.push(new TextField()); 
      titleTxt.push(new TextField()); 
      rewardTxt.push(new TextField()); 
      descripTxt.push(new TextField()); 
      achCoins.push(new coinSmall()); 
     {

在Achievements.as刪除兒童類

public function RemoveTextboxes(){ 
for (var k:int = 0; k < 30; k++) 
    { 
     removeChild(descripTxt[k]); 
     removeChild(titleTxt[k]); 
     removeChild(rewardTxt[k]); 
     removeChild(texts[k]); 
    } 
}

在Main.as類

achievementback.RemoveTextBoxes()

這裏是我的全部成果二等

是否在添加之前刪除它們？ – Xela 2015-03-31 00:14:13

@Xela我將他們刪除後，但在不同的類 – TomMcmann 2015-03-31 03:35:09

我不得不稍微修改代碼並註釋掉設置框中的文本以使其運行（因爲我缺少一些代碼）但是，我的問題似乎是文本框被刪除但你的綠色形狀留在舞臺上。添加一個矢量來保存所有這些並將它們添加到remove函數中。

我也不得不將您的自定義類更改回MovieClip和TextBox，因爲我沒有這些源代碼。

你會如何將他們從主類中刪除？ – TomMcmann 2015-03-31 03:33:17

我以爲你試圖刪除Main.as中的textfields。如果你想從Main.as中移除Achievement.as中的textfields，你可以在你的類Achievement.as中添加一個方法，名爲RemoveTextboxes（），然後從Main.as中調用myAchievementClassInstance.RemoveTextBoxes（）; – 2015-03-31 19:03:57

也許多一點的代碼可能會有所幫助。 – 2015-03-31 19:04:22

它應該是：

for (var k:int = 0; k < 30; k++) 
     { 
      achievementback.removeChild(achievementback.descripTxt[k]); 
      achievementback.removeChild(achievementback.titleTxt[k]); 
      achievementback.removeChild(achievementback.rewardTxt[k]); 
      achievementback.removeChild(achievementback.texts[k]); 
     }

更新你甚至添加這些的DisplayObject到矢量陣列？

它得到了同樣的錯誤作爲一個我最初發布的 – TomMcmann 2015-03-31 03:50:34

你是否將這些DisplayObject添加到你的矢量數組中？ – Xela 2015-03-31 04:00:50
