Class NetworkConfig

The configuration object used to start server, client and hosts

Inheritance

NetworkConfig

Namespace: Unity.Netcode

Syntax

[Serializable]
public class NetworkConfig

Fields

ClientConnectionBufferTimeout

The amount of seconds for the server to wait for the connection approval handshake to complete before the client is disconnected.

If the timeout is reached before approval is completed the client will be disconnected.

Declaration

[Tooltip("The amount of seconds for the server to wait for the connection approval handshake to complete before the client is disconnected")]
public int ClientConnectionBufferTimeout

Field Value

Type	Description
Int32

Remarks

The period begins after the Connect is received on the server. The period ends once the server finishes processing a Unity.Netcode.ConnectionRequestMessage from the client.

This setting is independent of any Transport-level timeouts that may be in effect. It covers the time between the connection being established on the Transport layer, the client sending a Unity.Netcode.ConnectionRequestMessage, and the server processing that message through ConnectionApproval.

This setting is server-side only.

ConnectionApproval

Whether or not to use connection approval

Declaration

[Tooltip("Whether or not to force clients to be approved before they connect")]
public bool ConnectionApproval

Field Value

Type	Description
Boolean

ConnectionData

The data to send during connection which can be used to decide on if a client should get accepted

Declaration

[Tooltip("The connection data sent along with connection requests")]
public byte[] ConnectionData

Field Value

Type	Description
Byte[]

EnableNetworkLogs

Whether or not to enable network logs.

Declaration

public bool EnableNetworkLogs

Field Value

Type	Description
Boolean

EnableSceneManagement

Enables scene management. This will allow network scene switches and automatic scene difference corrections upon connect. SoftSynced scene objects wont work with this disabled. That means that disabling SceneManagement also enables PrefabSync.

Declaration

[Tooltip("Enables scene management. This will allow network scene switches and automatic scene difference corrections upon connect.\nSoftSynced scene objects wont work with this disabled. That means that disabling SceneManagement also enables PrefabSync.")]
public bool EnableSceneManagement

Field Value

Type	Description
Boolean

EnableTimeResync

If your logic uses the NetworkTime, this should probably be turned off. If however it's needed to maximize accuracy, this is recommended to be turned on

Declaration

[Tooltip("Enable this to re-sync the NetworkTime after the initial sync")]
public bool EnableTimeResync

Field Value

Type	Description
Boolean

EnsureNetworkVariableLengthSafety

Whether or not to ensure that NetworkVariables can be read even if a client accidentally writes where its not allowed to. This costs some CPU and bandwidth.

Declaration

[Tooltip("Ensures that NetworkVariables can be read even if a client accidental writes where its not allowed to. This will cost some CPU time and bandwidth")]
public bool EnsureNetworkVariableLengthSafety

Field Value

Type	Description
Boolean

ForceSamePrefabs

Whether or not the netcode should check for differences in the prefabs at connection. If you dynamically add prefabs at runtime, turn this OFF

Declaration

[Tooltip("Whether or not the netcode should check for differences in the prefab lists at connection")]
public bool ForceSamePrefabs

Field Value

Type	Description
Boolean

LoadSceneTimeOut

The amount of seconds to wait for all clients to load or unload a requested scene

Declaration

[Tooltip("The amount of seconds to wait for all clients to load or unload a requested scene (only when EnableSceneManagement is enabled)")]
public int LoadSceneTimeOut

Field Value

Type	Description
Int32

NetworkIdRecycleDelay

The amount of seconds a NetworkId has to be unused in order for it to be reused.

Declaration

[Tooltip("The amount of seconds a NetworkId has to unused in order for it to be reused")]
public float NetworkIdRecycleDelay

Field Value

Type	Description
Single

NetworkTransport

The transport hosts the sever uses

Declaration

[Tooltip("The NetworkTransport to use")]
public NetworkTransport NetworkTransport

Field Value

PlayerPrefab

The default player prefab

Declaration

[Tooltip("When set, NetworkManager will automatically create and spawn the assigned player prefab. This can be overridden by adding it to the NetworkPrefabs list and selecting override.")]
public GameObject PlayerPrefab

Field Value

Type	Description
GameObject

ProtocolVersion

The protocol version. Different versions doesn't talk to each other.

Declaration

[Tooltip("Use this to make two builds incompatible with each other")]
public ushort ProtocolVersion

Field Value

Type	Description

Declaration

public const int RttWindowSize = 64

Field Value

Type	Description

SpawnTimeout

The amount of time a message should be buffered if the asset or object needed to process it doesn't exist yet. If the asset is not added/object is not spawned within this time, it will be dropped.

TickRate

The tickrate of network ticks. This value controls how often netcode runs user code and sends out data.

Declaration

[Tooltip("The tickrate. This value controls how often netcode runs user code and sends out data. The value is in 'ticks per seconds' which means a value of 50 will result in 50 ticks being executed per second or a fixed delta time of 0.02.")]
