《3D物体拖拽》

 

  1.要注意给相机加上3D射线检测

 

 

   2.要注意需要拖拽的物体上有碰撞器和拖拽的脚本

 

 

 3.在场景列表中加上EventSystem

 

 

 

--------------------代码如下---------------------

 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;

 

public class TZ : MonoBehaviour, IDragHandler
{
public void OnDrag(PointerEventData e)
{
Vector3 pos = Camera.main.WorldToScreenPoint(this.transform.position);
Vector3 gos = new Vector3(e.position.x, e.position.y, pos.z);
this.transform.position = Camera.main.ScreenToWorldPoint(gos);
this.transform.Rotate(0, Input.GetAxis("Mouse X") * 150 * Time.deltaTime, 0); //旋转
}
