Methods

CleanUpHandlers()

Call this to clean up the IntegrationTestSceneHandler and destroy the s_CoroutineRunner. Note: If deriving from NetcodeIntegrationTest or using Destroy() then you typically won't need to do this.

Declaration

public static void CleanUpHandlers()

Create(int, out NetworkManager, out NetworkManager[], int, bool, bool)

Creates NetworkingManagers and configures them for use in a multi instance setting.

Declaration

public static bool Create(int clientCount, out NetworkManager server, out NetworkManager[] clients, int targetFrameRate = 60, bool serverFirst = true, bool useMockTransport = false)

Parameters

Type	Name	Description
int	clientCount	The amount of clients
NetworkManager	server	The server NetworkManager
NetworkManager[]	clients	The clients NetworkManagers
int	targetFrameRate	The targetFrameRate of the Unity engine to use while the multi instance helper is running. Will be reset on shutdown.
bool	serverFirst	This determines if the server or clients will be instantiated first (defaults to server first)
bool	useMockTransport

Returns

Type	Description
bool

MakeNetworkObjectTestPrefab(NetworkObject, uint)

Normally we would only allow player prefabs to be set to a prefab. Not runtime created objects. In order to prevent having a Resource folder full of a TON of prefabs that we have to maintain, MultiInstanceHelper has a helper function that lets you mark a runtime created object to be treated as a prefab by the Netcode. That's how we can get away with creating the player prefab at runtime without it being treated as a SceneObject or causing other conflicts with the Netcode.

Declaration

public static void MakeNetworkObjectTestPrefab(NetworkObject networkObject, uint globalObjectIdHash = 0)

Parameters

Type	Name	Description
NetworkObject	networkObject	The networkObject to be treated as Prefab
uint	globalObjectIdHash	The GlobalObjectId to force

Parameters

Type	Name	Description
GameObject	networkObjectRoot

NetworkManager[]	clients

RegisterHandlers(NetworkManager, bool)
