Sync Projectile Shooting with Photon Networking

NomadicWarrior

Hello everyone, I'm trying to get nice shooting with Photon. I made "Projectile Shooting", it is a cannon and 2 players shoots each other, left/right direction. How can I sync Missile Bullet throwing position over network? I fully didn't understand how works Photon RPC, I have followed several tut and tried to use OnPhotonSerializeView. But I couldn't get nice and exact same sooting over network. Where I have to put PhotonViewComponent? Do I need PhotonView component to "Bullet" prefab? Right now bullet component has Photonview component and its observes Rigidbody. But also its not smooth, bullet appears in the middle of the screen via network view, local view is good. When I observe bullet with OnPhotonSerializeView, local ok but via network missile bullet falls right middle center.

I'M sorry for this long scripts. I was experimenting that which one will work good for me. Please need Help. Other moving, animating cannon works fine. Thanks in advance.

Nobody?(( There is a project Angry Bots Photon integrated but full code in JavaScript. I just wanted to know how works firing in this project. There is a script AutoFire.js. Tried to convert into C# but all codes is connected to each other((((

Hi,
You definitely should not attach PhotonView to bullet object. Instead, call RPC with position and direction of shot (if shot visuals required) and another RPC on bullet hit (to synchronize hit results including visuals).

Hello Vadim, Здравствуйте Вадим! Could you help me with script please.
Yes visuals are required.

using UnityEngine;
using System.Collections;

public class ThrowBullet : Photon.MonoBehaviour {

	public Transform bullet;
	public bool allowShoot;
	public GameObject BulletSpawnName;
	public int BulletForce = 2000; 
	public float ShotDelay;
	

	void Start () 
	{
		allowShoot = true;
	}
	

	void Update () 
	{

	}

	public void Fire ()
	{

		if (allowShoot == true) 
		{

			Vector3 bulletpos = BulletSpawnName.transform.position;
			GameObject Bullet = PhotonNetwork.Instantiate ("Bullet", bulletpos, Quaternion.identity, 0);
			Bullet.GetComponent<Rigidbody> ().AddForce (transform.forward * BulletForce);
			photonView.RPC("BulletTransit", PhotonTargets.All, bulletpos, BulletForce); 
		}
	}

	[PunRPC]
	public void BulletTransit (Vector3 bulletpos, int BulletForce)
	{
		bullet.transform.position = bulletpos * Time.deltaTime;
	}

	public IEnumerator DoTheDance() 
	{
		allowShoot = false;
		yield return new WaitForSeconds(ShotDelay); // waits 1 seconds
		allowShoot = true; 
	}
}

Am I on correct way? Thanks
