Classes

  Type Name Description
Public struct FAllSolverTasks Container for all steps required to fully update a solver.  
Public struct FChaosClusterUnionInterpolationData    
Public struct FChaosGeometryCollectionInterpolationData    
Public struct FChaosInterpolationResults    
Public class FChaosResultsManager    
Public struct FChaosRigidInterpolationData    
Public struct FClusterUnionProxyTimestamp    
Public class FDebugSubstep Debug only class used to control the pausing/stepping/substepping of a debug solver thread.  
Public class FDoubleBuffer Double Buffer Implementation - Not thread-safe requires external locks  
Public struct FGeometryCollectionProxyTimestamp    
Public class FGuardedTripleBuffer Triple buffer based on a single atomic variable, that guards against the consumer thread using old values.  
Public class FMultiBufferFactory    
Public class FPhysicsSolverAdvanceTask Task responsible for advancing the solver once data has been prepared and GT callbacks have fired  
Public class FPhysicsSolverBase    
Public class FPhysicsSolverEvents Base solver class storing events that will be used by the derived solver during the solve.  
Public class FPhysicsSolverFrozenGTPreSimCallbacks Task responsible for triggering any game thread callbacks before solver can advance (not scheduled if none are registered)  
Public class FPhysicsSolverProcessPushDataTask Task responsible for processing the command buffer of a single solver and preparing data before solver task and callbacks are run  
Public struct FProxyInterpolationBase    
Public struct FProxyInterpolationError Render interpolation that can correct errors from resimulation / repositions through a linear decay over N simulation tick.  
Public struct FProxyInterpolationErrorVelocity Render Interpolation that both perform the linear error correction from FProxyInterpolationError and takes incoming velocity into account to make a smoother and more organic correction of the error.  
Public struct FProxyTimestampBase    
Public class FScopedTraceSolverCallback    
Public class FScratchBuffer    
Public class FSingleBuffer Single Buffer Implementation  
Public struct FSingleParticleProxyTimestamp    
Public struct FSolverTasksPTOnly Container for all physics-thread steps required to update a solver This leaves out the game thread callbacks for situations that require and update only in a physics-thread context  
Public struct FSubStepInfo    
Public class FTripleBuffer Triple Buffer Implementation - Not thread-safe requires external locks  
Public class FUncheckedHeapAllocator    
Public class IBufferResource    
Public class IPhysicsProxyBase    
Public struct PhysicsProxyWrapper    
Public class TBufferedData Container type for double buffered physics data.  
Public class TChaosChunkedArray    
Public class TChaosReadWriteResource Lockable resource for use with chaos data.  
Public class TConstContainerItemHandle A handle to an item held by index in a container.  
Public class TConstHandle    
Public class TContainerItemHandle Same as TConstContainerItemHandle but for non-const containers/items  
Public class THandle    
Public class THandleArray    
Public class THandleData    
Public class THandleHeap    
Public class THashMappedArray A HashMap using FHashTable to index an array of elements of type TElementType, whcih should be uniquely identified by an object of type TIDType.  
Public struct THashMappedArrayTraits Default traits for THashMappedArray that works for all ID/Element pairs where the ID has a MurmurFinalize32 implementation and we can compare equality of Elements and IDs.  
Public class TPhysicsProxy Base object interface for solver objects.  
Public class TPoolBackedArray An array of (pointers to) Items with items allocated from an ObjectPool.  
Public struct TPoolBackedItemAdapter An adapter to allow use of types with the TPoolBackedArray.  
Public struct TTimestampProperty    
Public class TUncheckedFixedAllocator A fixed allocator without array bounds checking except in Debug builds.
