本文介绍Flash中处理用户交互事件的方法，包括鼠标和键盘事件的监听与响应。通过一个具体的Move类实例演示如何实现对象随键盘方向键移动及鼠标点击定位。

用户交互事件

类

可用属性

依赖类

鼠标事件

MouseEvent

CLICK

DOUBLE_CLICK

MOUSE_DOWN

MOUSE_MOVE

MOUSE_OUT

MOUSE_OVER

MOUSE_UP

MOUSE_WHEEL

ROLL_OUT

ROLL_OVER

mouseX

mouseY

flash.events.MouseEvent

键盘事件

KeyboardEvent

KEY_DOWN

KEY_UP

charCode

keyCode

flash.events.KeyboardEvent

flash.ui.Keyboard

获取键盘按键和鼠标点击事件的例子：Move.as

package { import flash.display.Sprite; import flash.events.KeyboardEvent; import flash.ui.Keyboard; import flash.events.MouseEvent; public class Move extends Sprite { private var bb:Ball; public function Move():void { init(); } private function init():void { bb = new Ball(0x00FF00); bb.x = stage.stageWidth/2; bb.y = stage.stageHeight/2; addChild(bb); //移动bb到某个位置 stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyboardDown); stage.addEventListener(MouseEvent.CLICK, onMouseClick); } public function onKeyboardDown(key:KeyboardEvent):void { switch(key.keyCode) { case Keyboard.UP: bb.y -= 10; break; case Keyboard.DOWN: bb.y += 10; break; case Keyboard.LEFT: bb.x -= 10; break; case Keyboard.RIGHT: bb.x += 10; break; default: trace(key.keyCode) break; } } public function onMouseClick(mouse:MouseEvent):void { bb.x = stage.mouseX; bb.y = stage.mouseY; } } }

在IDE环境下测试影片时，菜单快捷键和Tab键等会被IDE截获，需要在菜单中选择Control，Disable Keyboard Shortcuts 来解决此问题。
