photon networking spawning enemies

killeraled

hi, in the last few days i have been troubled about how to spawn enemies in photon, i have a working singleplayer version of this but the multiplayer side needs the enemies to spawn with a photon view number but every enemie i spawn using the code below comes out with a photonview number 0, and the "Network.Destroy(gameObject);" cant destroy objects with photonview number 0

this is not my code as i did have my spawner in javascript but javascript doesnt seem to work with photon

using UnityEngine;
using System.Collections;
 
public class spawnc : MonoBehaviour
{
   
    bool isSpawning = false;
    public float minTime = 5.0f;
    public float maxTime = 15.0f;
    public GameObject[] enemies;
   
    IEnumerator SpawnObject(int index, float seconds)
    {
       
       
        yield return new WaitForSeconds(seconds);
        Instantiate(enemies[index], transform.position, transform.rotation);
         
        isSpawning = false;
    }
   
    void Update ()
    {
        if(! isSpawning)
        {
            isSpawning = true; //Yep, we're going to spawn
            int enemyIndex = Random.Range(0, enemies.Length);
            StartCoroutine(SpawnObject(enemyIndex, Random.Range(minTime, maxTime)));
        }
    }
}

In my test game I have objects spawning.

This line in your code:
Instantiate(enemies[index], transform.position, transform.rotation);

...should use the PhotonNetwork.Instantiate method. Otherwise it will not get assigned a new PhotonView.

re:"this is not my code as i did have my spawner in javascript but javascript doesnt seem to work with photon"
I wrote this current prototype in Javascript using PUN as the starting point.
http://www.jtadeo.com/photon/snowball1/

When I have the prototype done, I plan on rewriting it in C#.

There is an error when you use PhotonNetwork.Instantiate(enemies[index], transform.position, transform.rotation);
and I think you need to have this function being done by the master client... it should be PhotonNetwork.InstantiateSceneObject, but I can't get that to work either.

Has anyone figured out how to properly do this, could you paste some example code?

using UnityEngine;
using UnityEngine;
using System.Collections;

public class SpawnEnemy : MonoBehaviour
{
	
	bool isSpawning = false;
	public float minTime = 5.0f;
	public float maxTime = 15.0f;
	public GameObject[] enemies;
	
	IEnumerator SpawnObject(int index, float seconds)
	{
		
		
		yield return new WaitForSeconds(seconds);
		SpawningEnemies ();
		
		isSpawning = false;
	}

	void SpawningEnemies () {
		if (!PhotonNetwork.isMasterClient) {
			PhotonNetwork.InstantiateSceneObject(enemies[index], transform.position, transform.rotation);
			Debug.LogError("Spawning Enemy");
		}
	}

	void Update ()
	{
		if(! isSpawning)
		{
			isSpawning = true; //Yep, we're going to spawn
			int enemyIndex = Random.Range(0, enemies.Length);
			StartCoroutine(SpawnObject(enemyIndex, Random.Range(minTime, maxTime)));
		}
	}
}

From PhotonNetwork.InstantiateSceneObject documentation: "Only the master client can Instantiate scene objects."
So checking if(!PhotonNetwork.isMasterClient) is probably wrong.

Right... do you know how to correctly make this work? (The other guy has been working on this for 2 months and I've tried different ways to get it to work and I'm not making any better progress.)

@jefftech
I remember there was an example on how to use the PhotonNetwork.InstantiateSceneObject in the PUN download. Check out the examples folder. It had a couple of PDF files that helped to explain how it worked along with scenes.

The Demo Boxes has 2 buttons. One is "Scene" and it allows you to instantiate a scene object - provided you are master client.
To help you with your issue, we need to know how it fails. Check the console output and if needed, post the error here.
