Syntax
USTRUCT&40;&41;
struct FActorSnapshotHash
Remarks
Every actor is hashed when it is saved so we can quickly check whether an actor has changed.
Variables
| Type | Name | Description | |
|---|---|---|---|
  |
uint32 | Crc32 | Crc32 hash of actor when it was snapshot. |
  |
int32 | Crc32DataLength | How many bytes of data were in the data were used for CRC32. Used to avoid computing hash. |
 |
FMD5Hash | MD5 | MD5 hash of actor when it was snapshot. |
  |
int32 | MD5DataLength | How many bytes of data were in the data were used for MD5. Used to avoid computing hash. |
  |
double | MicroSecondsForCrc | How many micro seconds it took to compute the actor CRC32 during saving. |
  |
double | MicroSecondsForMD5 | How many micro seconds it took to compute the MD5 hash. |
