UKismetGuidLibrary::IsValid_Guid

function Engine Blueprint Since unknown

#include "Kismet/KismetGuidLibrary.h"

Access: public Specifiers: staticBlueprintPureBlueprintThreadSafe

Description

Checks whether a GUID is valid, i.e. not the default all-zero value.

Caveats & Gotchas

• A GUID only fails this check if all four internal components are zero — it does not verify that the GUID refers to any real object, asset, or registered identifier, only that it isn't the default-constructed value.
• FGuid::NewGuid() is guaranteed to produce a valid GUID, but a GUID read from user input or deserialized data should be checked with this before use.

Signature
