actionscript 3 sleep?

问题

I have a simple actionscript function

var string:String = "TEXT REMOVED";
var myArray:Array = string.split("");
addEventListener(Event.ENTER_FRAME, frameLooper);

function frameLooper(event:Event):void {
    if(myArray.length > 0) {
        text1.appendText(myArray.shift());
    }else{
        removeEventListener(Event.ENTER_FRAME, frameLooper);
    }
}

And I want to have it sleep after calling the framelooper so it is a little bit slower. How could I do this?

btw, I'm fairly new and found this code on a tutorial, it's a text typing effect, if there is a better way of doing this please let me know.

回答1:

Use a Timer:

var string:String = "TEXT REMOVED";
var myArray:Array = string.split("");
var timer : Timer = new Timer (1000, myArray.length);
timer.addEventListener (TimerEvent.TIMER, frameLooper);
timer.start();

function frameLooper(event:Event):void {
    text1.appendText(myArray.shift());
}

This will execute the frameLooper on every second for exactly as many times as the length of the array.

I'm not saying this is better than the timer method, just an option

var string:String = "TEXT REMOVED";
var myArray:Array = string.split("");
addEventListener(Event.ENTER_FRAME, frameLooper);

const WAIT_TIME:int = 10;
var i:int = 0;
function frameLooper(event:Event):void {
    if(myArray.length > 0) {
        if(i==0){ 
            trace(myArray.shift()); 
            i = WAIT_TIME;
        };
    } else {
        removeEventListener(Event.ENTER_FRAME, frameLooper);
    }
    i--;
}
