BTW ENTITY::IS_ENTITY_DEAD is:
    static bool IS_ENTITY_DEAD(Entity entity) { static tIS_ENTITY_DEAD oIS_ENTITY_DEAD = (tIS_ENTITY_DEAD)(Memory::pattern("48 89 5C 24 ? 48 89 74 24 ? 57 48 83 EC 20 40 8A FA E8 ? ? ? ? 33 DB").count(1).get(0).get<void>()); return oIS_ENTITY_DEAD(entity); }

and

ENTITY::tIS_ENTITY_DEAD is:
typedef bool(__cdecl* tIS_ENTITY_DEAD)(Entity entity);
