TSubclassOf
#include "Templates/SubclassOf.h" Description
A UClass wrapper that enforces a type constraint at edit time and in C++. Use it in UPROPERTYs to restrict what class the user can assign in the editor.
Caveats & Gotchas
- • A null TSubclassOf is valid and common — always null-check before using it to spawn or CDO-access.
- • Assigning a class that doesn't inherit from T at runtime will fail silently in shipping builds but assert in debug.
- • Works with Blueprint classes — if you assign a Blueprint subclass of T, TSubclassOf will hold its UClass.
