b站教程

using UnityEngine;
using System.Collections;public class BallLauncher : MonoBehaviour {public float m_R;public NewBullet m_BulletPre;public Transform m_Target;private void Start(){StartCoroutine(Attack());}private void OnDestroy(){StopAllCoroutines();}private IEnumerator Attack(){while(true){NewBullet bullet = Instantiate(m_BulletPre, transform.position, Quaternion.identity);bullet.Attack(transform.position, GetRandomPoint(m_R), m_Target);yield return new WaitForSeconds(0.1f);yield return null;}}private Vector3 GetRandomPoint(float r){float x = Random.Range(-r, r);float ydis = m_Target.position.y - transform.position.y;float y = Random.Range(1, ydis);float z = Random.Range(-r, r);Vector3 vector3 = new Vector3(x, y, 0);return transform.position + vector3;}
}

第一种教程里面的

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Bullet : MonoBehaviour
{public float speed = 5f;private void Start(){Destroy(gameObject,15f);}private void OnDestroy(){StopAllCoroutines();}public void Attack(Vector3 start, Vector3 midPoint, Transform target){StartCoroutine(Move(start, midPoint, target));}private IEnumerator Move(Vector3 start, Vector3 midPoint, Transform target){for (float i = 0; i <= 1f; i += Time.deltaTime){Vector3 p1 = Vector3.Lerp(start, midPoint, i);Vector3 p2 = Vector3.Lerp(midPoint, target.position, i);Vector3 p = Vector3.Lerp(p1, p2, i);//让子弹移动到p点yield return StartCoroutine(MoveToPoint(p));}yield return StartCoroutine(MoveToObject(target));}private IEnumerator MoveToPoint(Vector3 p){yield return null;while (Vector3.Distance(transform.position, p) > 0.1f){Vector3 dir = p - transform.position;transform.up = dir;transform.position = Vector3.MoveTowards(transform.position, p, Time.deltaTime * speed);yield return null;}}private IEnumerator MoveToObject(Transform target){yield return null;while (Vector3.Distance(transform.position, target.position) > 0.1f){Vector3 dir = target.position - transform.position;transform.up = dir;transform.position = Vector3.MoveTowards(transform.position, target.position, Time.deltaTime * speed);yield return null;}}private void OnTriggerEnter(Collider other){if(other.gameObject.name=="Target"){Destroy(gameObject);}}
}

第二种：教程发给DeepSeek后的

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