我想保留我的键盘事件，但也可以添加鼠标事件。我的游戏键盘事件工作正常我只是不知道如何向它们添加鼠标事件。

我的舞台上有一些电影剪辑，左右上下等。

Character.as

[code]
if( m_keyboard.IsKeyDown( eKeyCodes.kLeftArrow ) )
{
    walking = true;
    x += 1;
    this.scaleX = 1;    
}

if( m_keyboard.IsKeyDown( eKeyCodes.kRightArrow ) )
etc....
[code]

eKeyCodes.as

[code]
static public const kLeftArrow:int = 37;
static public const kRightArrow:int = 39;

etc....
[/code]

Keyboard.as
[/code]
public class Keyboard
{
    private const kNumKeyCodes:int = 255;

    private var m_liveKeyState:Vector.<Boolean>;
    private var m_keyState:Vector.<Boolean>;
    private var m_lastKeyState:Vector.<Boolean>;

    public function Keyboard( stage:Stage )
    {
        // add handlers
        stage.addEventListener( KeyboardEvent.KEY_DOWN, OnKeyDown, false, 0, true );
        stage.addEventListener( KeyboardEvent.KEY_UP, OnKeyUp, false, 0, true );

        // vector is an array of booleans , the array is length is passed into the constructor as 255.
        m_keyState = new Vector.<Boolean>( kNumKeyCodes );
        m_lastKeyState = new Vector.<Boolean>( kNumKeyCodes );
        m_liveKeyState = new Vector.<Boolean>( kNumKeyCodes );

        // clear state
        for ( var i:int = 0; i<kNumKeyCodes; i++ )
        {
            // the whole array is false;
            m_keyState[i] = false;
            m_lastKeyState[i] = false;
            m_liveKeyState[i] = false;
        }



    }

    public function Update( ):void
    {

        for ( var i:int = 0; i<kNumKeyCodes; i++ )
        {
            m_lastKeyState[i] = m_keyState[i];
            m_keyState[i] = m_liveKeyState[i];
        }
    }

    private function OnKeyDown( e:KeyboardEvent ):void
    {

        m_liveKeyState[e.keyCode] = true;
        trace("m_liveKeyState = " + e.keyCode);
    }

    private function OnKeyUp( e:KeyboardEvent ):void
    {

        m_liveKeyState[e.keyCode] = false;
    }

    public function IsKeyDown( key:int ):Boolean           
    {
        // if key is down leftarrow ( 36 ) && 36 < 255 do no error; as key is a valid key;
        Assert( key >= 0 && key <= kNumKeyCodes, "Keyboard.IsKeyDown(): invalid key!" );

        return m_keyState[key];

    }

    /// Is key transitioning 

    public function IsKeyDownTransition( key:int ):Boolean
    {
        Assert( key >= 0 && key <= kNumKeyCodes, "Keyboard.IsKeyDownTransition(): invalid key!" );

        return !m_lastKeyState[key] && m_keyState[key]; 
    }
}
}
[/code]

我在想类似的东西......

TouchButtons.as
[code]
 icon.leftButton.addEventListner(MouseEvent.MOUSE_DOWN, leftButtonPressed, false, 0, true);
 icon.RightButton.addEventListner(MouseEvent.MOUSE_DOWN, rightButtonPressed, false, 0, true);


 public function leftButtonPressed( event:MouseEvent ):void
 {
      m_keyboard.IsKeyDown( eKeyCodes.kLeftArrow  );
 }
 etc...
[code]

但这似乎不起作用，有没有一种简单的方法可以做到这一点。

我猜你希望它像舞台活动一样工作。

public function leftButtonPressed( event:MouseEvent ):void
{
      m_liveKeyState[eKeyCodes.kLeftArrow] = true;
 }

朋友快疯了，我想将此代码转换为在触摸屏中使用

var leftBumpPoint:Point = new Point(-30, -55);
var rightBumpPoint:Point = new Point(70, -50);
var upBumpPoint:Point = new Point(0, -110);
var downBumpPoint:Point = new Point(0, 0);

var scrollX:Number = 0;
var scrollY:Number = 500;

var xSpeed:Number = 0;
var ySpeed:Number = 0;

var maxSpeedConstant:Number = 18;

var doubleJumpReady:Boolean = false;
var upReleasedInAir:Boolean = false;

var keyCollected:Boolean = false;
var doorOpen:Boolean = false;

stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDownHandler);
stage.addEventListener(KeyboardEvent.KEY_UP, keyUpHandler);

stage.addEventListener(Event.ENTER_FRAME, loop);
