So again the rule is: only send primitive data over the wire. If you're using procedural generation to add uniqueness to stuff in your game, you may send along the seed used to generate the object, so the receiver can generate it exactly the same way.

So in future we can agree on how to refer to this shared object in both our scenes.Īny data needed to initialize the object in the same stateĮg. The unique identifier this instance should have So if I want to spawn a new coin object, I look in my table and find the coin prefab at entry 5, and tell you "spawn a prefab #5" again without sending the entire object's component data, model, textures, animation, etc over the wire. This references a table of runtime-spawnable objects that both copies of the game hold. A spawn message might include:Īn identifier for the prefab we should clone We don't send the new object over the wire, we send the recipe the recipient needs to follow to achieve the same result. This is true even for spawning new objects. We just used a primitive message "Move GameObject #5 to these coordinates" to tell us what modification needed to be made to our existing object's transform. At no point did we convert a whole GameObject to a serialized form and send it over the wire. Notice that to send, receive, and interpret this message, we only need to use primitive types: strings, floats, integers, or enum values that boil down to integers. var messageType = (MessageType)message.ReadByte() What this might look like in code, assuming a binary message format that you can read like a BinaryReader, might be. This is a Vector3, so you send three floats, encoded as bytes or round-trippable strings depending on your format. Maybe you assign each object a unique name string or numeric ID when it's created - just make sure any method you use is consistent over the network, so all participants agree on the names of the objects involved. (so the receiver knows how to find the corresponding object in its replica of the game scene)Īgain, since this is your own system, you get to decide how you'll identify objects. Identifier for the GameObject you want to move Since you're making up your own networking code, how you identify each kind of message you can send is up to you - you might use enum values, or JSON objects with a string label "MessageType" etc. (so the receiver knows what kind of conversation we're having and can parse the following fields into your intended meaning). It's both heavier-weight and less effective than what we really want to do, which is:įor instance, if you want to tell the person at the other end of the line "GameObject #5 has moved to a new position" then you'd send something that looks like: There isn't a way to digest the whole thing into bytes to fit down the pipe then reconstitute it at the other end. Unity objects like GameObjects, Transforms, and other components are not set up for user serialization.
Unity transfer networkview to new server free#
Thanks in advance for any help, if more information is needed to clarify anything feel free to ask!ĭon't try to send GameObjects over the wire. Being it's all c# Udp, I'm using UdpClient and Sockets.I'm using a Udp server and client, all coded in C#, currently using MonoBehaviour(which I can remove if necessary).I am not using the unity built in networking tools, as this is for my own education.Important information I almost forgot to mention: I have tried changing everything to strings, then bytes, then back to strings, but I honestly don't even know where to start otherwise, as this seems excessive and wrong. Now I'm curious: How do I send gameobject data (transform, variables, actions, etc.) between server and client? I understand how you turn data into bytes with GetBytes() and then into strings with GetString(), but how do you deal with any other data types, like Gameobjects, or Transforms? However their are issues if you use an instanced RPC from 1 client to another.Recently I've learned about running my clients and servers on separate threads than main, and I was able to send string data back and forth, open/close sockets, etc. Support for cross scene network communication, yes you can have multiple clients in another scene all communicating with the server this is what the library is specifically designed for. Instance Type RPC's need to be added to also contain a NetworkView component and all RPC's for that object need to be assigned to the NetworkView Components arrayġ time initialization for Static references, Instanced methods are initialized in Awake. RPC Supports both Static and Instanced types RSGNetwork.GetClient(clientID).RPC("AuthenticateLogin", (int)LoginRequest.Failed) RSGNetwork.GetClient(clientID).RPC("AuthenticateLogin", (int)LoginRequest.Success) Public void Login(string GUID, string user = "")ĭebug.Log($"Client:")
