#include "Kismet/KismetGuidLibrary.h"

Description

Blueprint function library exposing FGuid operations: equality checks, validity, generation, and string conversion, for working with globally unique identifiers in Blueprints.

Caveats & Gotchas

• NewGuid() generates a new random/unique GUID on every call — it is not deterministic, so it's unsuitable for content that needs stable, reproducible identifiers across runs.
• Parse_StringToGuid returns Success=false on a malformed string rather than raising an error — always check the Success output rather than assuming OutGuid is valid.

Example

Generate a GUID and convert it to a string C++

const FGuid NewId = UKismetGuidLibrary::NewGuid();
const FString IdString = UKismetGuidLibrary::Conv_GuidToString(NewId);

Access	Type	Name	Description
public	function	UKismetGuidLibrary::Conv_GuidToString	Converts a GUID to its string representation, in the digits-only form 'AAAAAAAABBBBBBBBCCCCCCCCDDDDDDDD'.
public	function	UKismetGuidLibrary::EqualEqual_GuidGuid	Compares two GUIDs for equality, backing the Blueprint '==' operator node for the Guid type.
public	function	UKismetGuidLibrary::IsValid_Guid	Checks whether a GUID is valid, i.
public	function	UKismetGuidLibrary::NewGuid	Generates a new, statistically unique GUID.
public	function	UKismetGuidLibrary::NotEqual_GuidGuid	Compares two GUIDs for inequality, backing the Blueprint '!=' operator node for the Guid type.
public	function	UKismetGuidLibrary::Invalidate_Guid	Resets a GUID to its default, invalid (all-zero) value in place.
public	function	UKismetGuidLibrary::Parse_StringToGuid	Parses a string into a GUID, auto-detecting which of the standard EGuidFormats it's written in, and reports whether parsing succeeded.
