Spawning bullets on host and client Networking
Hey working on the following code.
Ok so what im trying to get to work: We have set up a local multiplayer game using: https://www.assetstore.unity3d.com/en/#!/content/14165
We made our own movement for player etc...
Were trying to get a shote script working that shoots the projectile on both the Hosts side and the clients side and is also adds the velocity to both sides...
Shooting script:
using System.Collections; using System.Collections.Generic; using UnityEngine;
public class earthshote : MonoBehaviour {
public Rigidbody Earthshote;
private float fireStart = 0f;
private float fireCooldown = 0.3f;
public float speed = 30;
// Use this for initialization
void Start()
{
}
// Update is called once per frame
void Update()
{
if (Input.GetButton("Earth1"))
{
if (Time.time > fireStart + fireCooldown)
{
fireStart = Time.time;
Rigidbody instantiatedProjectile = Network.Instantiate(Earthshote, transform.position, transform.rotation, 0) as Rigidbody;
instantiatedProjectile.velocity = transform.TransformDirection (Vector3.forward * speed);
}
}
}
Though I believe i might be just missing a few lines in the NetworkManager code that allow the spawning of the projectile (Networkmanager is from the asset):
using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public string serverName = "Example name"; // This is the name that will be displayed when returned by RefreshHostList()
public string serverPort = "25000"; // This is the port you'd like to use; useful to know/change if you need to port forward
public string username = ""; // What you want your username to be
public string password = ""; // The password for the server; needed to join a passworded server, or to create a server
public string maxPlayers = "4"; // Maximum number of players allowed in the server; CTRL-F MPINFO FOR IMPORTANT INFO

public bool privateServer = false; // If this is true, then the server will become password-protected, and only those with the password can join
public bool dedicated = false; // If true, the server host won't spawn as a player, but will still be joinable. A separate instance is required for the server host to join and play

// ===== GNINFO ===== //
//
// It is important to note, that any other Unity Game that uses the same Game Name as this
// will also be displayed, though connection may not be possible. I recommend changing this
// as soon as possible, to something with more obscurity. EG/ if your game were named Dario,
// something like Dario2014Alpha01131a would be obscure enough that the chances of someone else
// using it would be astronomically low. I personally use the convention GameNameDateVersion due to the high obscurity
//
// ================== //
// ===== MPINFO ===== //
//
// While maxPlayers is set to X, it actually has 1 subtracted from
// that value when used; this is because it actually treats the number
// as an array index (where Object 1 is indexed at 0)
//
// Because most players would reasonably assume that making a server only
// 1 slot would mean only 1 player is allowed (instead of 1 slot for 2 players),
// this caters to a perfectly reasonable assumption.
//
// It's important to know this when either customizing this script, or creating one from scratch,
// to prevent unwanted server issues
//
// ================== //
IF ANYONE ACTUALLY HELPS ME DO THIS I WILL BE VERY GREAT FULL BEEN TRYING TO GET THIS TO WORK FOR DAYS! thanks in advance

Sorry if the code doesnt look that clean, its written on a phone. Few pointers: Write variable names in camelCase, write class and method names in UpperCase. This makes the code more readable.
Thanks so much for taking out the time to help me. Your the really good person.
I only had 1 point to reward so i gave it to you ahaha. Thank you very much it works!! now im just trying to get the other stuff the work :) Thanks a lot!
