To check if your local player is authorized on a Tool Cupboard (TC) or detect enemy player IDs authorized on nearby bases:

1. Locate BuildingPrivlidge entity in entity list.
2. Read authorizedPlayers list (List<PlayerNameID> at offset 0x2A8).
3. Iterate the authorized SteamID64 array.

int authCount = Read<int>(authList + 0x18);
uintptr_t itemsArray = Read<uintptr_t>(authList + 0x10);
for (int i = 0; i < authCount; i++) {
    uint64_t steamId = Read<uint64_t>(itemsArray + 0x20 + (i * 0x18));
    std::string playerName = ReadUnicodeString(Read<uintptr_t>(itemsArray + 0x28 + (i * 0x18)));
    printf("[TC AUTH]: %s (%llu)\n", playerName.c_str(), steamId);
}

Useful for base raiding to see who lives in a base and check if they are currently online.

Confirmed working. List structure is standard .NET List<T> layout.
