RollbackSim::GroundTruthSnapshot struct
#include <Runtime/Core/Public/Policies/RollbackPolicy.h>

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

Stores field bytes plus the entity counts from TemporalFrameHeader and the per-field CurrentUsed values so the comparator can detect entity-count drift independently of the raw data check (e.g. correct resim values but fewer entities).

Public variables

std::vector<uint8_t> Data
Raw field bytes (one frame, header excluded).
uint32_t ActiveEntityCount
TemporalFrameHeader::ActiveEntityCount at capture.
uint32_t TotalAllocated
TemporalFrameHeader::TotalAllocatedEntities at capture.
std::vector<size_t> FieldUsed

Variable documentation

std::vector<size_t> RollbackSim::GroundTruthSnapshot::FieldUsed

FieldCompareInfo::CurrentUsed per field at capture, parallel to GetValidFieldInfos() order.
