Flash多点触摸屏程序教程

//这段代码用来显示每个触点下面的小红圈 package app.demo.MyTouchApp{ //adds a circle where you touch (no resize) import flash.display.*; import flash.events.*; import flash.net.*; import flash.geom.*; public class MyTouchApp extends Sprite { public function MyTouchApp() { //--------connect to TUIO----------------- TUIO.init(this,'localhost',3000,'',true); trace("MyTouchApp Initialized"); //---------------------------------------- addEventListener(TouchEvent.MOUSE_DOWN, touchDown); //run touchdown, when touched } public function touchDown(e:TouchEvent):void{ var curPt:Point = parent.globalToLocal(new Point(e.stageX, e.stageY)); //convert touch points to x,y var circle:Sprite = new Sprite(); //create a new sprite circle.graphics.lineStyle(10, 0xff0000); //set line width to 10px and red circle.graphics.drawCircle(0,0,40); // draw a 40px circle circle.x = curPt.x; //put it where touch is (x cord) circle.y = curPt.y; //put it where touch is (y cord) addChild(circle); //add the circle where touch happened } } } //这段代码允许你缩放舞台以及让触点下面出现小红圈 //下面的代码只是继承自RotatableScalable 类。里面的内容只针对上述讲的东西，因为每个App 构造函数不同。 package app.demo.MyTouchApp{ import flash.display.*; import flash.events.*; import flash.net.*; import flash.geom.*; import app.core.action.RotatableScalable; public class MyTouchApp extends RotatableScalable {//allows it to be scaled around public function MyTouchApp() { //--------connect to TUIO----------------- TUIO.init(this,'localhost',3000,'',true); trace("MyTouchApp Initialized"); //---------------------------------------- addEventListener(TouchEvent.MOUSE_DOWN, touchDown);//run touchdown, when touched } public function touchDown(e:TouchEvent):void { var curPt:Point=parent.globalToLocal(new Point(e.stageX,e.stageY));//convert touch points to x,y ...
