UKismetSystemLibrary::SetFieldPathPropertyByName

function Engine Blueprint Since 4.0

#include "Kismet/KismetSystemLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Sets a named TFieldPath property on Object to Value via reflection. Internal helper the Blueprint compiler generates for dynamic property-set nodes; not intended to be called directly.

Caveats & Gotchas

• Unlike the other SetXPropertyByName helpers (e.g. SetVectorPropertyByName), this one does not null-check the FFieldPathProperty it finds before calling SetPropertyValue_InContainer — a PropertyName that doesn't resolve to a field-path property on Object's class crashes instead of silently no-oping.
• Marked BlueprintInternalUseOnly, so it never appears in the Blueprint node picker directly.
