UKismetSystemLibrary::SetVector3fPropertyByName
#include "Kismet/KismetSystemLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintCallable
Description
Sets a named const FVector3f& 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
- • Marked BlueprintInternalUseOnly, so it never appears in the Blueprint node picker — the compiler emits a call to it automatically when a Blueprint node writes to this property type by name; you can't drag it onto a graph directly.
- • Targets FVector3f (single-precision) properties specifically, checked against TVariantStructure<FVector3f>::Get() — it will not write into a regular double-precision FVector property of the same name.
- • FVector3f is mainly used for GPU-facing or memory-compact data (e.g. Niagara, mesh data); most gameplay code should use SetVectorPropertyByName instead.
