模型放大缩小：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Enlarge : MonoBehaviour {
Vector2 oldPos1;
Vector2 oldPos2;
// Use this for initialization
void Start () {
}
// Update is called once per frame

//手势判断

手指滑动模型旋转：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class AiXiRotate : MonoBehaviour {
float Xspeed = 150f;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if(Input.GetMouseButton(0))
{
if(Input.touchCount == 1)
{
if(Input.GetTouch(0).phase == TouchPhase.Moved)//触摸的一根手指滑动
{
transform .Rotate(Vector3.up* Input.GetAxis("Mouse X") * (-Xspeed) * Time.deltaTime);
}
}
}
}
}
双击和长按手机屏幕：在这里必须得双击屏幕里的模型或长按模型使模型销毁
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class TouchTap : MonoBehaviour {
private float touchTime;
private bool newTouch=false ;

// Use this for initialization
void Start () {
}

//从相机发出一条射线
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

if(Physics.Raycast(ray,out hitInfo))
{
//if (hitInfo.collider.gameObject.name == "AiXi(Clone)")
//{
// if (Input.GetMouseButtonDown(0))
// {
// newTouch = true;
// touchTime = Time.time;
// Debug.Log(newTouch);
// }
// if(Input.GetMouseButtonUp(0))
// {
// newTouch = false;
// Debug.Log(newTouch);
// }
//}
if (hitInfo.collider.gameObject.name == "AiXi(Clone)")
{
//双击模型使模型销毁
if (Input.touchCount == 1 && Input.GetTouch(0).phase == TouchPhase.Began)//几个手指碰到屏幕&&刚点击屏幕
{

Destroy(hitInfo.collider.gameObject);
}
}
//长按
if (Input.touchCount == 1)

if (touch.phase == TouchPhase.Began)
{
newTouch = true;
touchTime = Time.time;
}
else if (touch.phase == TouchPhase.Stationary)//手指触摸屏幕但没有移动
{
