Functions

  Type Name Description

UpdateClientPlayer_External ( int32 PhysicsStep
)

 Update client player on GT.
Public function void Cache the current netmode for use in PT.
Public function void

Overridden from IRewindCallback

  Type Name Description
Public function Virtual void

ApplyCallbacks_Internal ( int32 PhysicsStep,
const TArray< Chaos::ISimCallbackObject* >& SimCallbackObjects
)

 Called after any presim callbacks are triggered and after physics data has marshalled over in order to modify the sim callback outputs
Public function Virtual void

InjectInputs_External ( int32 PhysicsStep,
int32 NumSteps
)

 Rewind API.
Public function Virtual void

ProcessInputs_External ( int32 PhysicsStep,
const TArray< Chaos::FSimCallbackInputAndObject >& SimCallbackInputs
)

 Called before any inputs are marshalled over to the physics thread.
Public function Virtual void

ProcessInputs_Internal ( int32 PhysicsStep,
const TArray< Chaos::FSimCallbackInputAndObject >& SimCallbackInputs
)

 Called before any sim callbacks are triggered but after physics data has marshalled over This means brand new physics particles are already created for example, and any pending game thread modifications have happened See ISimCallbackObject for recording inputs to callbacks associated with this PhysicsStep
Public function Virtual void Register a sim callback onto the rewind callback
Public function Virtual int32

TriggerRewindIfNeeded_Internal ( int32 LatestStepCompleted
)

 Called after sim step to give the option to rewind.
