UKismetSystemLibrary::SetVectorPropertyByName
#include "Kismet/KismetSystemLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintCallable
Description
Sets a named const FVector& 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.
- • Verifies the found FStructProperty's Struct pointer matches TBaseStructure<FVector>::Get() before writing, so a same-named property of a different struct type (e.g. FRotator or a custom struct) is safely skipped instead of corrupting memory.
