私は、ActionScript3とネストされたスイッチのケースで簡単なメニューを書いています。 現在のフレームを選択したメニューで確認し、選択されたメニューが別のメニューを参照している場合は、トランジションして選択したフレームに移動し、選択したメニューが現在のフレームであれば簡単なメッセージをトレースします。 しかし、選択されたメニューと現在のフレームが等しい場合、私はこの迷惑なメッセージを受け取り、問題を解決するために何をしなければならないか分かりません。ActionScript 3： "TypeError：Error＃1009：nullオブジェクト参照のプロパティまたはメソッドにアクセスできません。 onスイッチ
私のコードは次のとおりです。

//Loop through the buttons array
for (var i:uint = 0; i < buttonsArray.length; i++) {
//Add event listeners for the button
buttonsArray[i].addEventListener(MouseEvent.MOUSE_OVER, mouseOverButton);
buttonsArray[i].addEventListener(MouseEvent.CLICK, buttonClicked);
}
//Move the buttonBackground under the home button (= starting position)
buttonBackground.x = s1t1.x;
buttonBackground.y = s1t1.y;
//Make the buttonBackground a bit bigger than the home button
buttonBackground.width = s1t1.width + 10;
buttonBackground.height = s1t1.height + 10;
//Tween the buttonBackground to a random color using TweenMax
TweenMax.to(buttonBackground, 0.1, {tint: Math.random() * 0xffffff});
