unity 3d 讓物體沿弧線運動

using UnityEngine;  
using System.Collections;  
  
public class MoveCurve : MonoBehaviour {  
  
    public GameObject t1;    //開始位置  
    public GameObject t2;     //結束位置  
  // Update is called once per frame  
    void Update () {  
  
        //二者中心點  
        Vector3 center = (t1.transform .position + t2.transform.position) * 0.5f;  
  
        center -= new Vector3(0, 1, 0);  
  
        Vector3 start = t1.transform.position - center;  
        Vector3 end = t2.transform.position - center;  
  
        //弧形插值  
        transform.position = Vector3.Slerp(start,end,Time.time);  
        transform.position += center;  
          
    }  
}  

 

還有一種方法也能夠實現，代碼以下

 1 using UnityEngine;  
 2 using System.Collections;  
 3   
 4 public class ProjectileTest : MonoBehaviour  
 5 {  
 6     public GameObject target;   //要到達的目標  
 7     public float speed = 10;    //速度  
 8     private float distanceToTarget;   //二者之間的距離  
 9     private bool move = true;      
10   
11     void Start()  
12     {  
13         //計算二者之間的距離  
14         distanceToTarget = Vector3.Distance(this.transform.position, target.transform.position);    
15         StartCoroutine(StartShoot());  
16     }  
17   
18     IEnumerator StartShoot()  
19     {  
20   
21         while (move)  
22         {  
23             Vector3 targetPos = target.transform.position;  
24   
25             //讓始終它朝着目標  
26             this.transform.LookAt(targetPos);  
27   
28             //計算弧線中的夾角  
29             float angle = Mathf.Min(1, Vector3.Distance(this.transform.position, targetPos) / distanceToTarget) * 45;  
30             this.transform.rotation = this.transform.rotation * Quaternion.Euler(Mathf.Clamp(-angle, -42, 42), 0, 0);  
31             float currentDist = Vector3.Distance(this.transform.position, target.transform.position);  
32             if (currentDist < 0.5f)  
33                 move = false;  
34             this.transform.Translate(Vector3.forward * Mathf.Min(speed * Time.deltaTime, currentDist));  
35             yield return null;  
36         }  
37     }  
38   
39   
40 }
