UKismetSystemLibrary::SnapshotObject
#include "Kismet/KismetSystemLibrary.h"
Access: public
Specifiers: staticBlueprintCallable
Description
Notifies the current transaction (if any) that this object should be snapshot for an intermediate update, without closing out the full undo record. Editor-only.
Caveats & Gotchas
- • Internally calls SnapshotTransactionBuffer, which is designed for high-frequency intermediate updates (e.g. dragging a slider in a details panel) rather than a single discrete edit — use TransactObject for one-off changes.
- • Only available in the editor and only meaningful while a transaction is active.
