Struct ClientServerTickRate
Namespace: Unity.NetCode
Syntax
public struct ClientServerTickRate : IComponentDataFields
MaxSimulationLongStepTimeMultiplier
If the server cannot keep up with the simulation frequency with running MaxSimulationStepsPerFrame
ticks it is possible to allow each tick to run with a longer delta time in order to keep the game
time updating correctly. This means that instead of running two ticks with delta time N each, the
system will run a single tick with delta time 2*N. It is a less expensive but more inacurate way
of dealing with server performance spikes, it also requires the game logic to be able to handle it.
Declaration
public int MaxSimulationLongStepTimeMultiplierField Value
| Type | Description |
|---|---|
| Int32 |
MaxSimulationStepsPerFrame
If the server updates at a lower rate than the simulation tick rate it will perform multiple ticks in the same frame. This setting puts a limit on how many such updates it can do in a single frame. When this limit is reached the simulation time will update slower than real time. The network tick rate only applies to snapshots, the frequency commands and RPCs is not affected by this setting.
Declaration
public int MaxSimulationStepsPerFrameField Value
| Type | Description |
|---|---|
| Int32 |
NetworkTickRate
The rate at which the server sends snapshots to the clients. This can be lower than than the simulation frequency which means the server only sends new snapshots to the clients every N frames. The effect of this on the client is similar to having a higher ping, on the server it will save CPU time and bandwidth.
Declaration
public int NetworkTickRateField Value
| Type | Description |
|---|---|
| Int32 |
SendSnapshotsForCatchUpTicks
If the server has to run multiple simulation ticks in the same frame the server can either send snapshots for all those ticks or just the last one.
Declaration
public bool SendSnapshotsForCatchUpTicksField Value
| Type | Description |
|---|---|
| Boolean |
SimulationTickRate
The fixed simulation frequency on the server and prediction loop. The client can render at a higher or lower rate than this.
Declaration
public int SimulationTickRateField Value
| Type | Description |
|---|---|
| Int32 |
TargetFrameRateMode
If the server is capable of updating more often than the simulation tick rate it can either
skip the simulation tick for some updates (BusyWait) or limit the updates using
Application.TargetFrameRate (Sleep). Auto makes it use Sleep for dedicated server
builds and BusyWait for client and server builds (as well as the editor).
Declaration
public ClientServerTickRate.FrameRateMode TargetFrameRateModeField Value
| Type | Description |
|---|---|
| ClientServerTickRate.FrameRateMode |
