我正在嘗試創建一個多人 TPS，在其中我在本地（在我的編輯器中）實體化一個子彈并對其施加力。一旦它擊中其他玩家，我想稱該玩家為 TakeDamage RPC。
可悲的是，我遇到了這個我無法修復的奇怪錯誤訊息（已經花了我幾天的時間）。
我的彈丸腳本：
using Photon.Pun;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Arrow : MonoBehaviour
{
[SerializeField] float timeToDestroy;
[SerializeField] ParticleSystem hitEffect;
[SerializeField] TrailRenderer trailRenderer;
float timer;
private Rigidbody rb;
private Collider col;
private void Awake()
{
rb = GetComponent<Rigidbody>();
col = GetComponent<Collider>();
}
private void Update()
{
timer = Time.deltaTime;
if (timer > timeToDestroy) Destroy(gameObject);
}
private void OnCollisionEnter(Collision collision)
{
rb.isKinematic = true;
rb.velocity = Vector3.zero;
trailRenderer.enabled = false;
ShowHitEffect(collision.GetContact(0));
col.enabled = false;
if (collision.gameObject.CompareTag("Player"))
{
rb.isKinematic = true;
rb.velocity = Vector3.zero;
trailRenderer.enabled = false;
PhotonView pv = collision.gameObject.GetPhotonView();
Debug.Log("hit " pv.Controller.NickName);
pv.RPC("DealDamage", RpcTarget.All, PhotonNetwork.LocalPlayer.NickName, .5f, PhotonNetwork.LocalPlayer.ActorNumber);
}
Destroy(gameObject, 2f);
}
private void ShowHitEffect(ContactPoint cp)
{
hitEffect.transform.position = cp.point;
hitEffect.transform.forward = cp.normal;
hitEffect.Emit(1);
}
}
武器控制器腳本

using UnityEngine;
public class WeaponController : MonoBehaviourPunCallbacks

[SerializeField] float fireRate;
float fireRateTimer;

public ParticleSystem muzzleFlash;
public ParticleSystem hitEffect;
// Start is called before the first frame update
void Start()
{
fireRateTimer = fireRate;
}
private void Update()
{
if (!photonView.IsMine) return;
if (ShouldFire()) Fire();
}
bool ShouldFire()
{
fireRateTimer = Time.deltaTime;
if (fireRateTimer < fireRate) return false;
if (ammo.currentAmmo == 0) return false;
if (semiAuto && Input.GetKeyDown(KeyCode.Mouse0)) return true;
if (!semiAuto && Input.GetKey(KeyCode.Mouse0)) return true;
return false;
}
[PunRPC]
private void EmitMuzzleFlash()
{
muzzleFlash.Emit(1);
}
void Fire()
{
fireRateTimer = 0;
barrelPos.LookAt(aim.actualAimPos);
audioSource.PlayOneShot(gunshot);
EmitMuzzleFlash();
//photonView.RPC("EmitMuzzleFlash", RpcTarget.All);
ammo.currentAmmo--;
for (int i = 0; i < bulletPerShot; i )
{
GameObject currentBullet = Instantiate(bullet, barrelPos.position, barrelPos.rotation);
Rigidbody rigidbody = currentBullet.GetComponent<Rigidbody>();
rigidbody.AddForce(barrelPos.forward * bulletVelocity, ForceMode.Impulse);
// Projectile Instantiate
/*{

}

播放器控制器腳本（rpc 所在的位置）

UIController.instance.healthSlider.value = stats.GetCurrentHealth();
}
Cursor.lockState = CursorLockMode.Locked;
}
// Update is called once per frame
void Update()
{
FocusWindows();
}
void FocusWindows()
{
if (Input.GetKeyDown(KeyCode.Escape))
{
Cursor.lockState = CursorLockMode.None;
}
else if (Cursor.lockState == CursorLockMode.None)
{
if (Input.GetMouseButton(0))
{
Cursor.lockState = CursorLockMode.Locked;
}
}
}

奇怪的是，如果我使用“網路中的實體化箭頭”，則會呼叫 rpc。但這并不理想，因為它會在每次飛行時發送彈丸的變換。因此，我只想檢查本地（沒有 photonView 的箭頭）是否擊中敵人，然后呼叫該敵人的 rpc 以使他受到傷害并可能顯示來自損壞者的假專案。如果我的方法是幼稚/錯誤的，請告訴我一個更好的方法。
uj5u.com熱心網友回復：
如@derHugo 所述，我在 photonView 所在的同一腳本上轉移了 rpc 呼叫。我認為主要問題是我對 RPC 的理解。我認為 rpc 就像一個公共方法，您可以在其中呼叫它。我想我需要重新閱讀有關 rpc 和引發事件的檔案。
