Public function Virtual    

Functions

  Type Name Description
Public function Virtual void

ApplyCallbacks_Internal ( int32 PhysicsStep,
const TArray< 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
)

 Called before inputs are split into potential sub-steps and marshalled over to the physics thread.
Public function Virtual void

PostResimStep_Internal ( int32 PhysicsStep
)

 Called after each rewind step.
Public function Virtual void

PreResimStep_Internal ( int32 PhysicsStep,
bool bFirstStep
)

 Called before each rewind step.
Public function Virtual void

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

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

ProcessInputs_Internal ( int32 PhysicsStep,
const TArray< 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 void

SetResimDebugInfo_Internal ( const FResimDebugInfo& ResimDebugInfo
)

 Called When resim is finished with debug information about the resim
Public function Virtual int32

TriggerRewindIfNeeded_Internal ( int32 LatestStepCompleted
)

 Called after sim step to give the option to rewind.
