FlashAS 3.0 学习笔记(二)

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。
