Unity Vector3.Slerp使用范例

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

 public class TestSlerp : MonoBehaviour
 {
     public Transform a;
     public Transform b;

     void Start()
     {

     }
     bool kaishi = false;
     float T;
     void Update()
     {
         if (Input.GetKeyDown(KeyCode.S))
         {
             kaishi = true;
             T = Time.time;
             print(Time.time + " SSSSSSSSSSS  " + T);

         }
         if (kaishi)
         {
             Debug.DrawLine(Vector3.zero, new Vector3(, , ), Color.red);
             //for (int i=0;i<11;++i)
             //{
             Vector3 center = (a.position + b.position) * 0.5f;
             center -= new Vector3(, , );
             Vector3 temp1 = a.position - center;
             Vector3 temp2 = b.position - center;
             print(Time.time + "   " + T);
             Vector3 c = Vector3.Slerp(temp1, temp2, (Time.time-T) * 0.1f);

             c += center;
             transform.position = c;
             //Debug.DrawRay(center, c, Color.red);
             //Debug.DrawRay(Vector3.zero, c, Color.red);
             Debug.DrawLine(center, c, Color.blue);
             Debug.DrawLine(Vector3.zero, c, Color.blue);

             // print(i);
         }
     }
 }

最终效果如下：

修改如下：

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

 public class TestSlerp : MonoBehaviour {
     public Transform a;
     public Transform b;
     void Start () {

     }
     void Update () {
          Debug.DrawLine(Vector3.zero,new Vector3(,,),Color.red);
         for (int i=;i<;++i)
         {
             Vector3 center = (a.position + b.position) *0.5f;
             center -= new Vector3(,,);
             Vector3 temp1 =a.position - center;
             Vector3 temp2 =b.position - center;
             Vector3 c = Vector3.Slerp(temp1, temp2, i * 0.1f);
             Debug.DrawLine(center, c, Color.blue);
             Debug.DrawLine(Vector3.zero, c, Color.blue);
         }
     }
 }

效果如下：
