UKismetSystemLibrary::EndTransaction

function Engine Blueprint Since unknown

#include "Kismet/KismetSystemLibrary.h"

Access: public Specifiers: staticBlueprintCallable

Description

Attempts to end the current undo transaction. Only actually closes the transaction if its action counter is 1. Editor-only.

Caveats & Gotchas

• If BeginTransaction was called multiple times (nested), this only decrements the counter — the transaction stays open until the counter reaches 1 and this is called a final time.
• Returns -1 on failure (e.g. no active transaction); a return value of 1 confirms the transaction was actually closed.
• Only available in the editor.

}
