RollbackSim struct

#include <Runtime/Core/Public/Policies/RollbackPolicy.h>

TRollbackMode policy for LogicThread — owns all rollback state and logic.

Template method bodies live in Core/Private/RollbackImpl.h (included only by LogicThread.cpp, which instantiates them); non-template bodies in RollbackSim.cpp.

Public types

struct GroundTruthSnapshot

Snapshot of the ground-truth ECS frame captured before rollback resimulation.

Public static variables

static bool Enabled constexpr

Enables rollback paths in LogicThread.

static uint32_t RollbackFrameCount constexpr
