UKismetSystemLibrary::SetObjectPropertyByName
#include "Kismet/KismetSystemLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintCallable
Description
Sets a named UObject* 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.
- • Validates Value's type against the property's declared PropertyClass with IsA before writing — assigning an object of an incompatible class is silently ignored rather than producing a type-mismatch error.
