    I would love to see a multiplayer game that is turned based. Most Unity Content providers are showing samples of the same type of game where they control a player with movement and firing, etc. What about an example of a game where it is turned based and there are components that are not really assigned to a player but to a game manager. For example, if you have a spinner in the beginning of the game where it decides which player goes first. How does this work, do you spawn a network prefab or run an RPC to tell each system to run the same code. And, if so how do you sink the random generator variable because only the host client should actually determine the value. It then gets complicated on synched buttons that are shared. And, if you have a common UI (One that doesn't float over and belongs to a player) how do you sync things like text displays, turns left, money, health bars, etc. There are few examples of this type of multiplayer Netcode games. (Thanks!!!)

    I think this fixes it:
    Change the line in MoveProjectile.cs from "rb.velocity = rb.transform.forward * shootForce;" to "rb.MovePosition(rb.position + (rb.transform.forward * shootForce) * Time.deltaTime);" and it should fix the issue.

    As a "player" I'm using the standard 3rd person armature that comes with the Starter Assets. My problem is that when I press "play" and then "Start Host" on the NetworkManager, my "player" will fall through the ground. I can fix it by setting the ground to something negative like -2 but in the example here, that is not done, everything appears to be left to zero/default. What am I doing differently if anyone can tell from my problem description?

    • @TheRusBaron
      @TheRusBaron Рік тому

      As documentation says - Spawning can always be done on the host/server. If you want to give a client control over spawning objects, you need to implement a server RPC that you call on the client to spawn the object.
      So, use RPCs

    • @NerradKramp
      @NerradKramp Рік тому +1

      Hi - just in case you don't get an official response right away and are anxious to resolve you are correct the player will be spawned where you network manager is. You just need to have your character controller or any attached script override the default instantiate position to where you would like your spawn point to be. So somewhere on you character you need to have a method like:
      (Pseudo code)
      Public class RepositionMyPlayer : NetworkBehaviour
      {
      public override void OnNetworkSpawn()
      {
      transform.position = myStartingPosition;
      }
      }
      Just remember you need your class to inherit from NetworkBehaviour

      That's probably because client authoritative movement is easy to grasp and get started with. He explained the basics of using RPCs and NetworkVariables, so with that and the official documentation that was mentioned/provided in the description, you should have enough info to get started in experimenting with different authoritative models yourself. Good luck with your endeavours!

    After lobby, i have to move to the Level Selection scene which selects which level to choose.
    That level scene is an addressable which is being downloaded from cloud.
    But net code does not seem to work with addressable scene.
    Any advice?
    I am thinking two options :
    1)
    Use RPC to manually load the addressable scene on all clients
    2)
    Make all the contents of the scene an addressable prefab and then include the empty scene in build settings which can be loaded through netcode. Then instantiate the adressable when the scene is loaded by netcode.

    Excellent video! I have two questions:
    1) The project files from your Patreon page seems to be for the complete version. How can I get the "before" version (with the animations and such, but not the networking code added during the video) so I can work through the tutorial?
    2) The completed code works great on one machine: I can run a local build and also run it within the Unity editor, and they talk to each other happily. When I run a build on a second machine, I get an error "Cannot start Client while an instance is already running". It's very strange that this only happens across two machines! What's going on, and how can this be fixed?

      1. Send us a message on patreon to try to provide a copy of the project without networking.
      2. This tutorial is just for showing the networking logic, you need further steps to make it work online , by adding relay. We have full course on Udemy to show the whole process and build full online game.

      @@BinaryLunar Ah, I didn't realize there was an additional component needed. I may just go with local multiplayer + Parsec instead. Thanks!
