一起学习AS3.0：键盘的操作

键盘的点击与弹起：

Source:        
stage.addEventListener(KeyboardEvent.KEY_DOWN, xKeyDown);
stage.addEventListener(KeyboardEvent.KEY_UP, xKeyUp);

function xKeyDown(event:KeyboardEvent):void{
        kb.text = "点击"+event.keyCode;
};

function xKeyUp(event:KeyboardEvent):void{
        kb.text = "弹起"+event.keyCode;
};


按键状态的确认：

Source:        
var space_flag:Boolean = false;

stage.addEventListener(KeyboardEvent.KEY_DOWN,xKeyDown);
stage.addEventListener(KeyboardEvent.KEY_UP,xKeyUp);
stage.addEventListener(Event.ENTER_FRAME,xEnterFrame);

function xKeyDown(evt:KeyboardEvent):void{
    if(evt.keyCode == Keyboard.SPACE){
        space_flag = true;
    }
}

function xKeyUp(evt:KeyboardEvent):void{
    if(evt.keyCode == Keyboard.SPACE){
        space_flag = false;
    }
}

function xEnterFrame(evt:Event):void{
    if(space_flag){
                mc.gotoAndStop(2);
        }else{
                mc.gotoAndStop(1);
    }
}                        


键盘的KeyCode表示：

Source:        
stage.addEventListener(KeyboardEvent.KEY_DOWN, KeyDown);

function KeyDown(evt:KeyboardEvent){                                                                                                          
        code_text.text                 = String(evt.keyCode);
        location_text.text         = String(evt.keyLocation);
        ctrl_text.text                 = String(evt.ctrlKey);
        shift_text.text                 = String(evt.shiftKey);
        alt_text.text                 = String(evt.altKey);
}
