Actionscript 3.0可以连续赋予鼠标单击保持功能吗？

Question

我有很多必须点击。 但MouseEvent.CLICK每次单击只能执行一次。 还有其他方法可以让鼠标单击保持并重复该功能吗？

Answer 1

考虑：

1. 在MouseEvent.MOUSE_DOWN ，创建一个间隔以触发绑定到MouseEvent.CLICK的方法
2. 在MouseEvent.MOUSE_UP ，清除间隔

这是一些未经测试的代码（用英语阅读得很好）：

import flash.display.DisplayObject;
import flash.events.MouseEvent;
import flash.events.TimerEvent;
import flash.utils.Timer;

var displayObject:DisplayObject = new DisplayObject(); // the existing object that is clickable, i'm only instantiating for the purpose of this demo
displayObject.addEventListener(MouseEvent.CLICK,function(e:MouseEvent) { // again the click handler for illustrative purposes
    trace(getTimer().toString(10)+': clicked!');
}):

// here is the flow i'm talking about
var interval:Timer = new Timer(1000/stage.frameRate);
interval.addEventListener(TimerEvent.TIMER,triggerClick);

displayObject.addEventListener(MouseEvent.DOWN,startRepeatClick);
displayObject.addEventListener(MouseEvent.UP,stopRepeatClick);

function startRepeatClick(e:MouseEvent) {
    interval.start();
}

function stopRepeatClick(e:MouseEvent) {
    interval.stop();
}

function triggerClick(e:TimerEvent) {
    var clickEvent:MouseEvent = new MouseEvent(MouseEvent.CLICK,true,false,displayObject.mouseX,displayObject.mouseY);
    displayObject.dispatchEvent(clickEvent);
}
