Unity实现物体弧线运动到规定的坐标

using UnityEngine;
using System.Collections;
 
public class Run : MonoBehaviour
{
 public GameObject target;  //要到达的目标
 public float speed = 10;  //速度
 private float distanceToTarget;  //两者之间的距离
 private bool move = true;  
 
 void Start()
 {
 //计算两者之间的距离
 distanceToTarget = Vector3.Distance(this.transform.position, target.transform.position); 
 StartCoroutine(StartShoot());
 }
 
 IEnumerator StartShoot()
 {
 
 while (move)
 {
  Vector3 targetPos = target.transform.position;
 
  //让始终它朝着目标
  this.transform.LookAt(targetPos);
 
  //计算弧线中的夹角
  float angle = Mathf.Min(1, Vector3.Distance(this.transform.position, targetPos) / distanceToTarget) * 45;
  this.transform.rotation = this.transform.rotation * Quaternion.Euler(Mathf.Clamp(-angle, -42, 42), 0, 0);
  float currentDist = Vector3.Distance(this.transform.position, target.transform.position);
  if (currentDist < 0.5f)
  move = true;
  this.transform.Translate(Vector3.forward * Mathf.Min(speed * Time.deltaTime, currentDist));
  yield return null;
 }
 }
 
 
}
