This plugin offers an easy-to-use solution for Netcode's NetworkBehaviour class, streamlining the approach to networking mods with Server and Client RPCs. By utilizing the CustomMessagingHandler of Netcode, it networks RPCs and their System.Serializable (Marked with [Serializable]) or INetworkSerializable parameters. While this is currently only in the Lethal Company directory, it can be expanded to other games upon request. Please reach out on Discord or via an issue here on Github for questions or contact.
To integrate Runtime Unity Netcode Patcher in your Unity project, follow these steps:
dotnet add package NicholaScott.BepInEx.RuntimeNetcodeRPCValidator --version 0.2.0 and add an [BepInDependency(RuntimeNetcodeRPCValidator.MyPluginInfo.PLUGIN_GUID, RuntimeNetcodeRPCValidator.MyPluginInfo.PLUGIN_VERSION)] attribute to your [BepInPlugin].NetcodeValidator and call NetcodeValidator.PatchAll(). When you wish to revert any patches applied call Dispose(), or UnpatchSelf() if you want to keep the instance for re-patching.For more robust examples check the Github Repo of the UnitTester plugin, which is used during development to verify codebase.
// Example of using NetcodeValidator
namespace SomePlugin {
[BepInPlugin("My.Plugin.Guid", "My Plugin Name", "0.1.1")]
[BepInDependency(RuntimeNetcodeRPCValidator.MyPluginInfo.PLUGIN_GUID, RuntimeNetcodeRPCValidator.MyPluginInfo.PLUGIN_VERSION)]
public class MyPlugin : BaseUnityPlugin {
private NetcodeValidator netcodeValidator;
private void Awake()
{
netcodeValidator = new NetcodeValidator("My.Plugin.Guid");
netcodeValidator.PatchAll();
}
// [[OPTIONAL DISPOSE TO UNPATCH]]
private void OnDestroy()
{
netcodeValidator.Dispose();
}
}
}
// Example of using Server or Client RPCs. Naming conventions require the method to end with the corresponding attribute name.
namespace SomePlugin {
// This assumes you've declared a BaseUnityPlugin and Harmony instance elsewhere. Including the previous snippet about NetcodeValidator.
[HarmonyPatch(typeof(Terminal), "Start")]
private static class Patch {
[HarmonyPrefix]
private static void AddToTerminalObject(Terminal __instance) {
__instance.gameObject.AddComponent<PluginNetworkingInstance>();
}
}
public class PluginNetworkingInstance : NetworkBehaviour {
[ServerRpc]
public void SendPreferredNameServerRpc(string name) {
// Log the received name
Debug.Log(name);
// Tell all clients what the sender told us
TellAllOtherClients(NetworkBehaviourExtensions.LastSenderId, name);
}
[ClientRpc]
public void TellAllOtherClients(ulong senderId, string name) {
Debug.Log(StartOfRound.Instance.allPlayerScripts.First(playerController => playerController.actualClientId == senderId).playerUsername + " is now " + name);
}
[ClientRpc]
public void RunClientRpc() {
// Send to the server what our preferred name is, f.e.
SendPreferredNameServerRpc("Nicki");
}
private void Awake()
{
// Are we a server instance?
if (IsHost)
StartCoroutine(WaitForSomeTime());
}
private IEnumerator WaitForSomeTime()
{
// We need to wait because sending an RPC before a NetworkObject is spawned results in errors.
yield return new WaitUntil(() => NetworkObject.IsSpawned);
// Tell all clients to run this method.
RunClientRpc();
}
}
}
Ensure you have the following components within the environment:
Utilize the NetworkBehaviourExtensions.LastSenderId property to retrieve the ID of the last RPC sender. This will always be NetworkManager.ServerClientId on the clients.
