UBlueprintInstancedStructLibrary::EqualEqual_InstancedStruct

function Engine Blueprint Since 5.0

#include "Kismet/BlueprintInstancedStructLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Checks whether two FInstancedStructs hold the same struct type and equal values, backing the "==" compact node in Blueprint.

Caveats & Gotchas

• Equality requires both the stored UScriptStruct type and the underlying data to match — two instanced structs holding equal values of different types are not equal.
• Struct comparison ultimately relies on the contained UScriptStruct's own equality behaviour (native operator== or CPF_IsPlainOldData memberwise compare); custom structs without proper equality support may compare in unexpected ways.
• This is defined inline in the header, so calling it from C++ is identical to writing `A == B` directly on the FInstancedStructs.

Signature

static bool EqualEqual_InstancedStruct(UPARAM(Ref) const FInstancedStruct& A, UPARAM(Ref) const FInstancedStruct& B) { return A == B; }

Parameters

Name	Type	Description	Default
A	const FInstancedStruct&	First instanced struct to compare.	—
B	const FInstancedStruct&	Second instanced struct to compare.	—

Return Type

bool

Example

Compare two instanced structs C++

FInstancedStruct A = FInstancedStruct::Make(FVector(1, 2, 3));
FInstancedStruct B = FInstancedStruct::Make(FVector(1, 2, 3));
bool bEqual = UBlueprintInstancedStructLibrary::EqualEqual_InstancedStruct(A, B); // true
