Detailed Description

Project configuration settings specific to how the Simulation class behaves.

Member Enumeration Documentation

DataConsistency

enum DataConsistency

strong

Enumerator
Full	When a NetworkBehaviour's data changes, the server will send all properties whose changes have not been acknowledged. This option consumes more bandwidth, but guarantees that each NetworkBehaviour has consistent state.
Eventual	When a NetworkBehaviour's data changes, the server will only send the newly changed properties. This option consumes less bandwidth, but a NetworkBehaviour may have inconsistent state at times (some properties up-to-date but not others).

InputTransferModes

enum InputTransferModes

strong

Enumerator
Redundancy	Send delta compressed and redundant input, used for most games
RedundancyUncompressed	Send redundant input, use for games with small input structs (like fps games) and high player count
LatestState	Only send latest input state, useful for VR, etc.

SimulationTimeMode

enum SimulationTimeMode

strong

The time mode that the NetworkRunnerUpdaterDefault uses to calculate the delta time for the simulation update.

Enumerator
UnscaledDeltaTime	Use Time.UnscaledDeltaTime. Time is not affected by timescale and keeps running when the editor is paused.
DeltaTime	Use Time.DeltaTime. Only for GameMode.Single. Can be used to allow for timescale changes in gameplay or to pause the game and continue without interruption when stopping at a debug breakpoint.

HostMigration

bool HostMigration

If, in host mode, we should allow host migration if the current host leaves.

InputDataWordCount

int InputDataWordCount

Input Data Word Count

InputTransferMode

InputTransferModes InputTransferMode

The way which input is transferred

MaxObjectDestroysSentPerPacket

byte MaxObjectDestroysSentPerPacket = 32

The amount of object destroys Fusion sends per packet. Increasing this value means Fusion prioritizes sending more destroys before regular state changes. Setting this value to 255, can help with problems when unloading scenes with many runtime spawned objects (such as Spawned/Despawned being called on those objects multiple times).

ObjectDataConsistency

DataConsistency ObjectDataConsistency

How the server chooses to send NetworkObject updates to balance consistency and bandwidth consumption.

PlayerCount

int PlayerCount = 10

The default number of players allowed to join a game instance. Can also be changed in code when starting Fusion.

ReplicationFeatures

NetworkProjectConfig.ReplicationFeatures ReplicationFeatures = NetworkProjectConfig.ReplicationFeatures.Scheduling

Scheduling is the default.

SimulationUpdateTimeMode

SimulationTimeMode SimulationUpdateTimeMode = SimulationTimeMode.UnscaledDeltaTime

The time mode that the Runner uses to update the simulation.

-

TickRateSelection

TickRate.Selection TickRateSelection = TickRate.Default

The default tick rate to use. Can also be changed in code when starting Fusion.

Topology

Topologies Topology

The topology used
