Remarks

Replication Controllers

The RepControllers are the pieces of the TNetworkedSimulationModel that make up the role-specific functionality (Server, Autonomous Client, and Simulated Client). Mainly they NetSerialize, Reconcile, and have Pre/Post sim tick functions. The TNetworkedSimulationModel is still the core piece that ticks the sim, but the Replicators do everything else in a role-specific way.

Functions

Name Description

Public function Const

int32

 

GetProxyDirtyCount

(
    TNetworkSimBufferContainer< Model >...
)

Used for client shadowstate compares. Should just call GetDirtyCount() on the buffer you are replicating.

Public function

void

 

NetSerialize

(
    const FNetSerializeParams& P,
    TNetworkSimBufferContainer< Model >...,
    const TSimulationTicker< TTickSetti...
)

NetSerialize: just serialize the network data. Don't run simulation steps. Every replicator will be NetSerialized before moving on to Reconcile phase.

Public function

void

 

PostSimTick

(
    TDriver* Driver,
    const TNetworkSimBufferContainer< M...,
    const TSimulationTicker< TTickSetti...,
    const FNetSimTickParameters& TickP...
)

Called after input processing. Should finalize the frame and do any smoothing/interpolation. This function is not allowed to modify the buffers or tick state, or even call the simulation/Update function.

Public function

void

 

PreSimTick

(
    TDriver* Driver,
    TNetworkSimBufferContainer< Model >...,
    TSimulationTicker< TTickSettings > ...,
    const FNetSimTickParameters& TickP...
)

Called prior to input processing. This function must update Ticker to allow simulation time (from TickParameters) and to possibly get new input.

Public function

void

 

Reconcile

(
    TSimulation* Sim,
    TDriver* Driver,
    TNetworkSimBufferContainer< Model >...,
    TSimulationTicker< TTickSettings > ...
)

Reconcile: called after everyone has NetSerialized. "Get right with the server": this function is about reconciling what the server told you vs what you have extrapolated or forward predicted locally.
