Declaration
inline bool class_is_a(ClassId child, ClassId parent)Performs `class is a` as part of compiled Blueprint execution and object interaction.
| Parameter | Type | Meaning |
|---|---|---|
child | ClassId | Value supplied for child. Keep referenced or pointed-to data valid for the complete call. |
parent | ClassId | Value supplied for parent. Keep referenced or pointed-to data valid for the complete call. |

Example
C++ example
#include "blueprint_spawn.hpp"
// Assume these named values have been initialized with valid data:
// ClassId child
// ClassId parent
auto result = epok::bp::class_is_a(child, parent);Trade-offs and warnings
Check the return value; `false` is part of normal control flow for many PSX resource operations.
