[Unity3d ios]开发- 实现iphone手指拖拽_unity新版输入系统touch.onfingermove

unity新版输入系统touch.onfingermove
  1. using UnityEngine;
  2. using System.Collections;


  3. public class Test : MonoBehaviour {
  4. private Vector3 screenPoint;
  5. private Vector3 offset;
  6. // Update is called once per frame
  7. void Update () {
  8. for (int i = 0; i < Input.touchCount; ++i) {
  9. if (Input.GetTouch(i).phase == TouchPhase.Began) {
  10. screenPoint = Camera.main.WorldToScreenPoint(gameObject.transform.position);


  11. offset = gameObject.transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.GetTouch(i).position.x, Input.GetTouch(i).position.y, screenPoint.z));
  12. }
  13. if(Input.GetTouch(i).phase == TouchPhase.Moved) {
  14. Vector3 curScreenPoint = new Vector3(Input.GetTouch(i).position.x, Input.GetTouch(i).position.y, screenPoint.z);


  15. Vector3 curPosition = Camera.main.ScreenToWorldPoint(curScreenPoint) + offset;
  16. transform.position = curPosition;
  17. }
  18. }
  19. }

Unity3D手机中Input类touch详解:


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。

  1. static var aa:int;
  2. function Update () {
  3. if(Input.touchCount>0)
  4. {
  5. print(Input.touchCount);
  6. }
  7. }
  8. function OnGUI()
  9. {
  10. GUI.Label(Rect(34,34,34,34),"sdff");
  11. }
  12.   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。


    1. // Prints number of fingers touching the screen
    2. //输出触摸在屏幕上的手指数量
    3. function Update () {
    4. var fingerCount = 0;
    5. for (var touch : Touch in Input.touches) {
    6. if (touch.phase != TouchPhase.Ended && touch.phase != TouchPhase.Canceled)
    7. fingerCount++;
    8. }
    9. if (fingerCount > 0)
    10. print ("User has " + fingerCount + " finger(s) touching the screen");
    11. }

        3.让cube随着touch 移动代码:

    1. static var count:int; //定义touchCount数
    2. var particle_:GameObject;//定义存放cube对象
    3. var touchposition:Vector3; //存储移动三维坐标值
    4. function Update () {
    5. if(Input.touchCount>0)
    6. {
    7. count+=Input.touchCount;}
    8. 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]
    9. {
    10. touchposition=Input.GetTouch(0).deltaPosition;  //[color=Red]获取手指touch最后一帧移动的xy轴距离[/color]
    11. particle_.transform.Translate(touchposition.x*0.01,touchposition.y*0.01,0);//[color=Red]移动这个距离[/color]
    12. }}
    13. function OnGUI()
    14. {
    15. GUI.Label(Rect(10,10,100,30),"cishu:"+count.ToString());
    16. GUI.Label(Rect(10,50,100,30),touchposition.ToString());
    17. }
