AActor::DebugShowOneComponentHierarchy
#include "GameFramework/Actor.h"
Access: public
Description
Prints the hierarchy of a single scene component and its children to the log. Called recursively by DebugShowComponentHierarchy to build the full tree output.
Caveats & Gotchas
- • NestLevel is passed by reference and mutated during recursion; if you call this directly, pass a local int32 initialised to 0 to avoid misaligned indentation.
- • Prefer DebugShowComponentHierarchy for printing the full actor hierarchy — this function is the recursive worker and is not meant to be the entry point.
