UKismetSystemLibrary::SetClassPropertyByName
#include "Kismet/KismetSystemLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintCallable
Description
Sets a named TSubclassOf<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.
- • Checks Value->IsChildOf(MetaClass) before writing, so passing a class that doesn't derive from the property's declared MetaClass is silently dropped rather than erroring.
