將數組項（形狀）添加到舞臺

我正在編程一個flash AS3文件，在AS3文件中，我使用舞臺上的點（您放置自己）創建一個形狀，然後填充它們之間的部分。我想我已經成功地將形狀添加到數組中。現在，我在清理舞臺後在舞臺上形狀出現問題。將數組項（形狀）添加到舞臺

根據你的代碼，行是一個新的形狀，沒有陣列。這是第一個錯誤。

var shapeArray:Array/* of flash.display.Shape */ = [] /* of flash.display.Shape */; 
var lines:Shape = new Shape(); 

// what was wrong 
function showit(e:Event):void 
{ 
    // lines is a shape, no array, thus lines[0] will throw a runtime error 
    // also, if you wanted to get the first shape, type the reference to 
    // Shape instead to String 
    var shapeArray:String = lines[0]; 
} 

// doing it better 
function showit(e:Event):void 
{ 
    if (!shapeArray || shapeArray.length == 0) 
    return; // nothing to do here 

    const shape:Shape = shapeArray[0] as Shape; 
    if (shape && !shape.parent) // ensure it exists and hasn't been added yet. 
    addChild(shape) // show it 
}

我不明白，我想我補充說，在這一部分： { 功能toevoegen（E：事件）：無效 { //添加 shapeArray.push（線）; 跟蹤（shapeArray） } } （PS我不知道回覆系統是如何工作的） –

我誤解你的代碼，再檢查吧。 –

我仍然無法獲得放在舞臺上的陣列中保存的形狀。或者我現在做的事情真的錯了嗎？ –

將數組項（形狀）添加到舞臺
