Namespace: Unity.NetCode
Syntax
public struct NetworkSnapshotAck : IComponentData, IQueryTypeParameterFields
DeviationRTT
The round trip time average deviation from the EstimatedRTT. It is not a real standard deviation but an approximation using a simpler exponential smoothing average.
Declaration
public float DeviationRTTField Value
| Type | Description |
|---|---|
| Single |
EstimatedRTT
The calculated exponential smoothing average connection round trip time.
Declaration
public float EstimatedRTTField Value
| Type | Description |
|---|---|
| Single |
LastReceivedRemoteTime
The last remote time stamp received by the connection. The remote time is sent back (via command for the client or in the snapshot for the server) and used to calculate the round trip time for the connection.
Declaration
public uint LastReceivedRemoteTimeField Value
| Type | Description |
|---|---|
| UInt32 |
LastReceivedSnapshotByLocal
The field has a different meaning on the client vs on the server:
Client: it is the last received ghost snapshot from the server.
Server: record the last command tick that has been received. Used to discard either out of order or late commands.
Declaration
public NetworkTick LastReceivedSnapshotByLocalField Value
| Type | Description |
|---|---|
| NetworkTick |
LastReceivedSnapshotByRemote
The last snapshot (tick) received from the remote peer.
For the client, it respresent the last received snapshot received from the server.
For the server, it is the last acknowledge packet that has been received by client.
Declaration
public NetworkTick LastReceivedSnapshotByRemoteField Value
| Type | Description |
|---|---|
| NetworkTick |
LastReceiveTimestamp
The local time stamp at which the connection has received the last message. Used to calculate the elapsed "processing" time and reported to the remote peer to correctly update the round trip time.
Declaration
public uint LastReceiveTimestampField Value
| Type | Description |
|---|---|
| UInt32 |
NumLoadedPrefabs
Server-only, the number of ghost prefabs loaded by remote client. On the client is not used and it is always 0.
Declaration
public uint NumLoadedPrefabsField Value
| Type | Description |
|---|---|
| UInt32 |
ReceivedSnapshotByLocalMask
Client-only, a bitmask that indicates which of the last 32 snapshots has been received from the server. On the server it is always 0.
Declaration
public uint ReceivedSnapshotByLocalMaskField Value
| Type | Description |
|---|---|
| UInt32 |
RemoteInterpolationDelay
The reported interpolation delay reported by the client (in number of ticks).
Declaration
public uint RemoteInterpolationDelayField Value
| Type | Description |
|---|---|
| UInt32 |
ServerCommandAge
How late the commands are received by server. Is a negative fixedPoint Q24:8 number that measure how many ticks behind the server was when he received the command, and it used as feedback by the NetworkTimeSystem to synchronize the ServerTick such that the client always runs ahead of the server. A positive number indicates that the client is running behind the server. A negative number indicates that the client is running ahead of the server.
Declaration
public int ServerCommandAgeField Value
| Type | Description |
|---|---|
| Int32 |
Methods
IsReceivedByRemote(NetworkTick)
Return true if the snapshot for tick tick has been received (from a client perspective)
or acknowledged (from the servers POV)
Declaration
public bool IsReceivedByRemote(NetworkTick tick)Parameters
| Type | Name | Description |
|---|---|---|
| NetworkTick | tick |
Returns
| Type | Description |
|---|---|
| Boolean |
