AS3运行code连续而按住一个按键 - 空气中的iOS / Android的 [英] AS3 Run code continuously while holding a Button down - Air For iOS/Android

问题描述

我正在开发在Flash CS6的的iOS游戏。 我有一个基本的运动测试，我把在 Event.MOUSE_DOWN 处理程序。

I am developing an iOS game in Flash CS6. I have a basic movement test that I put in an Event.MOUSE_DOWN handler.

我很期待/想是当我拿着我的手指向下按钮，玩家将继续前进，直到我停止触摸屏幕。

What I'm expecting/wanting is when I held my finger down on the button, that the player would keep moving until I stop touching the screen.

不过会发生什么，是我要保持不断的拍打，以保持玩家的移动 - 而不是仅仅握住我的手指上的按钮，玩家继续移动

What happens though, is I have to keep constantly tapping to keep the player moving - rather than just hold my finger on the button and the player keeps moving.

什么code，我应该用它来完成我想要的吗？

What code should I use to accomplish what I want?

推荐答案

要做到这一点，你需要不断地在两者之间的MouseEvent.MOUSE_DOWN 运行功能和 Event.MOUSE_UP 作为的MouseEvent.MOUSE_DOWN只会被派往每preSS一次。

To accomplish this, you'll need to run a function continuously in between MouseEvent.MOUSE_DOWN and Event.MOUSE_UP as MouseEvent.MOUSE_DOWN will only get dispatched one time per press.

下面是一个简单的脚本来做到这一点：

Here is a simple script to do just that:

myButton.addEventListener(MouseEvent.MOUSE_DOWN,mouseDown);

function mouseDown(e:Event):void {
    stage.addEventListener(MouseEvent.MOUSE_UP,mouseUp); //listen for mouse up on the stage, in case the finger/mouse moved off of the button accidentally when they release.
    addEventListener(Event.ENTER_FRAME,tick); //while the mouse is down, run the tick function once every frame as per the project frame rate
}

function mouseUp(e:Event):void {
    removeEventListener(Event.ENTER_FRAME,tick);  //stop running the tick function every frame now that the mouse is up
    stage.removeEventListener(MouseEvent.MOUSE_UP,mouseUp); //remove the listener for mouse up
}

function tick(e:Event):void {
    //do your movement
}

顺便说一句，你可能要使用触摸事件，因为它提供了多点触摸控制更加灵活。但如果你只是以往任何时候都允许一个项目是pssed在任何给定的时间$ P $，这不是一个问题。

As an aside, you may want to use the TOUCH events, as it gives more flexibility with multi-touch control. Though if you're only ever going to allow one item to be pressed at any given time, it's not an issue.

要做到这一点，只需添加 Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT 在你的文档类，然后用适当的触摸事件替换的MouseEvents听众：

TO do that, just add Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT in your document class, then replace your MouseEvent listeners with the appropriate touch event:

的MouseEvent.MOUSE_DOWN 变成了： TouchEvent.TOUCH_BEGIN
侦听MouseEvent.MOUSE_UP 变成了： TouchEvent.TOUCH_END

MouseEvent.MOUSE_DOWN becomes: TouchEvent.TOUCH_BEGIN
MouseEvent.MOUSE_UP becomes: TouchEvent.TOUCH_END
