AIR2.0中的多点触摸手势识别测试

by shine on 五.26, 2010, under Flash Platform, 技术研究

AIR2.0众所周知支持多点触摸的手势识别了。

默认包含以下几个已经封装好的识别,当然你也可以使用多点触控事件来写自己的手势代码：

ROTATE:旋转
ZOOM:缩放
PAN:平移
SWIPE:滑动

测试代码如下：

import flash.events.TransformGestureEvent;

stage.addEventListener(TransformGestureEvent.GESTURE_ROTATE,gesturerotate);

stage.addEventListener(TransformGestureEvent.GESTURE_ZOOM,gesturezoom);

stage.addEventListener(TransformGestureEvent.GESTURE_PAN,gesturepan);

stage.addEventListener(TransformGestureEvent.GESTURE_SWIPE,gestureswipe);

function gesturerotate(e:TransformGestureEvent){

MovieClip(ss).rotation+=e.rotation;

}

function gesturezoom(e:TransformGestureEvent){

wtxt.text=”sx:”+e.scaleX.toString()+”\n”+

“sy:”+e.scaleY.toString();

MovieClip(ss).scaleX+=e.scaleX-1;

MovieClip(ss).scaleY+=e.scaleY-1;

}

function gesturepan(e:TransformGestureEvent){

wtxt.text=”px:”+e.offsetX.toString()+”\n”+

“py:”+e.offsetY.toString();

MovieClip(ss).x+=e.offsetX;

MovieClip(ss).y+=e.offsetY;

}

function gestureswipe(e:TransformGestureEvent){

wtxt.text=”is swipe x:”+ e.offsetX+” y:”+e.offsetY;

}
