PUN2 | 该过程被调用两次

Question

I am currently using PUN2 to create a multiplayer shooting game. Participation in a room and synchronization of movement and bullets have been implemented.

However, the processing when hit is performed twice. Perhaps this is because the exact same object that exists on the two devices is processing each shot. (maybe)

How do I avoid duplicate hit handling?

Code:

flow : The shooter assigns its own identification number to the shell and fires it → Anyone who hits the shell will take damage.

Player.cs

private void OnCollisionEnter(Collision collider)
{
        BulletController bulletController = collider.gameObject.GetComponent<BulletController>();

        if (photonView.Owner.ActorNumber != bulletController.shooterUserId)
        {
            photonView.RPC(nameof(Damaged), RpcTarget.All, bulletController.Damage, bulletController.shooterUserId);
            bulletController.Remove();
        }
}

[PunRPC]
void Damaged(int damage, int userId)
{
    var hashtable = new Hashtable();
    hashtable["HP"] = HP;
    PhotonNetwork.LocalPlayer.SetCustomProperties(hashtable);

    if (photonView.IsMine)
    {
        HP -= damage;
        if (HP <= 0)
        {
            this.gameObject.SetActive(false);
            HP = 0;

            if (userId != photonView.OwnerActorNr)
                photonView.RPC("KilledPlayer", RpcTarget.Others);

        }
    }
}

[PunRPC]
void KilledPlayer()
{
    GameSparksLeaderboard.SaveXP(100);
}

I just forgot to attach photonView.IsMine . It's important, but it's easy to forget ...
