Flash AS3，如何将循环暂停几秒钟

Question

我有这个AS3脚本（工作正常），我只想使循环每次暂停几秒钟，然后它才能继续循环。 就像我喜欢它停止几毫秒一样。

 var myText:String; var counter:int = 0; var format : TextFormat = new TextFormat(); format.size = 16; format.font = "Verdana"; format.bold = true; format.color = 0x000000; var textField : TextField = new TextField(); textField.width = 200; textField.height = 50; textField.selectable = false; textField.wordWrap = true; textField.defaultTextFormat = format; textField.x = textField.y =0; addChild(textField); var textLoader:URLLoader = new URLLoader(new URLRequest("text.txt")); textLoader.addEventListener(Event.COMPLETE, function(e:Event){initText(e.target.data);}); function initText(string:String):void{ myText = string; addEventListener(Event.ENTER_FRAME, writeText); } function writeText(e:Event):void{ if (counter <= myText.length){ textField.text = myText.substr(0,counter); counter++; /*What I can put here to make it pause for a while*/ } else{ removeEventListener(Event.ENTER_FRAME,writeText); } }

您的代码很好，您需要对其进行一些调整。

function initText(string:String):void
{
    myText = string; 
    addEventListener(Event.ENTER_FRAME, writeText); 
}

// Variable to keep the next print time in milliseconds.
var nextPrint:int;

function writeText(e:Event):void
{
    // Function getTimer() returns time in milliseconds since app start.
    // Skip this frame if time is not right.
    if (getTimer() < nextPrint) return;

    // Variable nextPrint is initially 0 so the first char will print immediately.

    if (counter <= myText.length)
    {
        textField.text = myText.substr(0, counter); 
        counter++;

        /*What I can put here to make it pause for a while*/
        // Print next character in ~100 ms.
        nextPrint = getTimer() + 100;
    }
    else
    {
        removeEventListener(Event.ENTER_FRAME, writeText); 
    }
}
