unity 3d 让物体沿弧线运动

using UnityEngine;  
using System.Collections;  
  
public class MoveCurve : MonoBehaviour {  
  
    public GameObject t1;    //开始位置  
    public GameObject t2;     //结束位置  
  // Update is called once per frame  
    void Update () {  
  
        //两者中心点  
        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;  
          
    }  
}  

 

还有一种方法也可以实现，代码如下

using UnityEngine;  
using System.Collections;  
  
public class ProjectileTest : 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 = false;  
            this.transform.Translate(Vector3.forward * Mathf.Min(speed * Time.deltaTime, currentDist));  
            yield return null;  
        }  
    }  
  
  
}
