Unity实现弧形移动效果

本文实例为大家分享了Unity实现弧形移动效果的具体代码，供大家参考，具体内容如下

一、实现效果

二、第一种实现方法——弧形插值

using UnityEngine;

public class ArcMove : MonoBehaviour
{
 public GameObject curGo;//当前物体
 public GameObject targetGo;//目标物体

public float value;

private void Update()
 {
   //计算中心点
   Vector3 center = (curGo.transform.position + targetGo.transform.position) / 2;

center -= new Vector3(0, value, 0);

Vector3 start = curGo.transform.position - center;
   Vector3 end = targetGo.transform.position - center;

//弧形插值
   curGo.transform.position = Vector3.Slerp(start, end, Time.time / 200);
   curGo.transform.position += center;

//判定是否到达目标点
   float dis = Vector3.Distance(curGo.transform.position, targetGo.transform.position);
   if (dis <= 1)
   {
     Debug.Log("到达目标点");
   }
 }
}

三、第二种实现方法——计算弧线中的夹角

using UnityEngine;
using System.Collections;

public class ArcMove : MonoBehaviour
{
 public GameObject curGo;//当前物体
 public GameObject targetGo;//目标物体

public float speed = 2;//速度
 public int rotationAngle = 60;//旋转的角度

private float distanceToTarget;//两者之间的距离
 private bool move = true;//是否移动

void Start()
 {
   //计算两者之间的距离
   distanceToTarget = Vector3.Distance(curGo.transform.position, targetGo.transform.position);

StartCoroutine(Move());
 }

/// <summary>
 /// 移动
 /// </summary>
 private IEnumerator Move()
 {
   //移动到目标点停止移动
   while (move)
   {
     Vector3 targetPos = targetGo.transform.position;
     targetPos.z = 0;

//让它始终朝着目标
     curGo.transform.LookAt(targetPos);

//计算弧线中的夹角
     float angle = Mathf.Min(1, Vector3.Distance(curGo.transform.position, targetPos) / distanceToTarget) * rotationAngle;
     curGo.transform.rotation = curGo.transform.rotation * Quaternion.Euler(Mathf.Clamp(-angle, -42, 42), 0, 0);
     float currentDist = Vector3.Distance(curGo.transform.position, targetGo.transform.position);
     if (currentDist < 0.5f)
     {
       move = false;
       Debug.Log("到达目标点");
     }
     curGo.transform.Translate(Vector3.forward * Mathf.Min(speed * Time.deltaTime, currentDist));
     yield return null;
   }
 }
}
