Began	A finger touched the screen.
Moved	A finger moved on the screen.
Stationary	A finger is touching the screen but hasn't moved.
Ended	A finger was lifted from the screen. This is the final phase of a touch.
Canceled	The system cancelled tracking for the touch, as when (for example) the user puts the device to her face or more than five touches happened simultaneously. This is the final phase of a touch.

多点触控时，下标是从0开始的，两个触控点下标就是0,1。

代码如下：

 
          nt touchCount = 2;  
          // 触摸帧的数量 
         
          if 
          (touchCount == Input.touchCount())<br>{ 
         
          vector2 touchPosition1 = Input.GetTouch(0).position; 
         
          vector2 touchPosition2 = Input.GetTouch(1).position; 
         
          }

1.Input.touchCount 触摸随之增长，一秒50次增量。

2.Input.GetTouch(0).phase==TouchPhase.Moved 手指滑动中最后一帧滑动的状态是运动的。

3.TouchPhase 触摸的几个状态。

4.Touch.deltaPosition 增量位置（Input.GetTouch(0).deltaPosition）最后一帧滑动的值，只返回xy轴坐标，也可用vector3（z轴为0），所以一般用vector2接收。

static var aa:int;
function Update () {
if(Input.touchCount>0)
{
print(Input.touchCount);
}
}
function OnGUI()
{
GUI.Label(Rect(34,34,34,34),"sdff");
}

touchCount指的是触摸帧的数量。要注意的是：touch事件只能在模拟器或者真机上运行（已测试通过），大约一秒钟touch不放。touchCount+50次左右。2.Input.touches 触摸列表。

// Prints number of fingers touching the screen
//输出触摸在屏幕上的手指数量
function Update () {
var fingerCount = 0;
for (var touch : Touch in Input.touches) {
if (touch.phase != TouchPhase.Ended && touch.phase != TouchPhase.Canceled)
fingerCount++;
}
if (fingerCount > 0)
print ("User has " + fingerCount + " finger(s) touching the screen");
}

3.让cube随着touch 移动代码：

static var count:int; //定义touchCount数
var particle_:GameObject;//定义存放cube对象
var touchposition:Vector3; //存储移动三维坐标值
function Update () {
if(Input.touchCount>0)
{
count+=Input.touchCount;}
if((Input.touchCount>0&&Input.GetTouch(0).phase==TouchPhase.Moved)) //[color=Red]如果点击手指touch了  并且手指touch的状态为移动的[/color]
{
touchposition=Input.GetTouch(0).deltaPosition;  //[color=Red]获取手指touch最后一帧移动的xy轴距离[/color]
particle_.transform.Translate(touchposition.x*0.01,touchposition.y*0.01,0);//[color=Red]移动这个距离[/color]
}}
function OnGUI()
{
GUI.Label(Rect(10,10,100,30),"cishu:"+count.ToString());
GUI.Label(Rect(10,50,100,30),touchposition.ToString());
}
