mcSkyblockCC

Lua scripts for a ComputerCraft / CC:Tweaked banking and casino support network in a Minecraft Skyblock world.

The project is built around a central rednet server that stores player account balances, with client computers for ATMs, teller desks, customer displays, door access, and casino-facing screens.

Features

• Central account server using rednet protocols.
• Debit-card style account lookup from disks containing a CheckSum.txt file.
• Simple ATM balance checker plus a larger menu-driven ATM interface.
• Teller desk script for writing account balances from an authorised bank computer.
• Customer leaderboard monitor that polls balances and ranks players.
• Door lock script with employee password access and a redstone output.
• Display and sound scripts for casino or shop atmosphere.
• Placeholder files for future gambling games.

Requirements

• Minecraft with ComputerCraft or CC:Tweaked.
• Computers or advanced computers for the server and client terminals.
• Wired or wireless modems configured for rednet.
• Disk drives and disks for debit cards.
• Monitors for customer-facing screens.
• Redstone output support for the door lock script.
• A speaker peripheral if using musicController.lua.

Project Layout

Path	Purpose
serverPassiveQuery.lua	Main rednet account server. Handles reads, writes, updates, transfers, registration, and checksum lookup.
ATM.lua	Simple ATM flow that reads a disk checksum and prints the account balance.
ATM2.lua	Menu-based ATM UI with balance checking and early transfer UI work.
tellerDesk.lua	Teller terminal for setting account balances through the Write protocol.
autoTeller.lua	Animated teller/customer screen.
doorLock.lua	Password-protected door control using a redstone output.
musicController.lua	Loops a speaker sound.
CustomerScreens/leaderboard.lua	Monitor leaderboard for account balances.
CustomerScreens/Pysop.lua	Casino-style idle display loop.
GambleGames/*.lua	Empty placeholder scripts for future gambling games.
Info.txt	Reference list of sample account checksums and network notes.

Data Model

The main server expects account data under /Data on the server computer.

Each account balance is stored in a file named after the account checksum:

/Data/CHz01G.txt

The file content should be the current numeric balance:

100

The server also refers to:

• /Data/registeredComputers.txt for computer ID to owner checksum mappings.
• /Data/info.txt for checksum lookup by name.

Debit card disks should contain:

/disk/CheckSum.txt

with the matching checksum as the first line, for example:

CHz01G

Rednet Protocols

serverPassiveQuery.lua listens for these protocol names:

Protocol	Message format	Result
Read	CHECKSUM	Returns the account balance from /Data/CHECKSUM.txt.
Write	CHECKSUM:VALUE	Sets an account balance. Intended for the authorised bank computer.
Update	CHECKSUM:DELTA	Adds DELTA to the current account balance.
Transaction	FROMCHECKSUM:TOCHECKSUM:VALUE	Moves value from one account to another.
Register	CHECKSUM	Registers the sender computer ID to a checksum.
getChecksum	Account name	Looks up a checksum from /Data/info.txt.

Most client scripts currently send requests to computer ID 5, which is noted in Info.txt as the main server.

Setup

1. Place serverPassiveQuery.lua on the main banking server computer.
2. Ensure the server computer's ID is 5, or update each client script to use the correct server ID.
3. Attach modems on the sides used by the scripts, or update the hard-coded rednet.open(...) sides.
4. Create /Data on the server computer.
5. Add one balance file per account, such as /Data/CHz01G.txt.
6. Create /Data/registeredComputers.txt and /Data/info.txt if you want registration and checksum lookup.
7. Place client scripts on the matching in-game computers.
8. Create debit card disks with /disk/CheckSum.txt containing a valid checksum.

Running

Run the server first:

serverPassiveQuery

Then run client scripts on their intended computers:

ATM
ATM2
tellerDesk
doorLock
CustomerScreens/leaderboard
CustomerScreens/Pysop

ComputerCraft normally lets you run a program by its filename without the .lua extension.

Configuration Notes

Several values are currently hard-coded and should be checked before deployment:

• Server computer ID: 5.
• ATM modem side: back.
• ATM disk drive side: Bottom in the current scripts.
• Server modem sides: top and left.
• Teller desk modem side: right.
• Leaderboard modem side: left.
• Leaderboard monitor name: monitor_2.
• Door lock redstone output side: left.
• Door lock employee and admin passwords.
• Account checksums and player names in Info.txt, ATM2.lua, and CustomerScreens/leaderboard.lua.

Current Status

• ATM.lua is a simple balance checker.
• ATM2.lua has a clickable menu and balance screen, but withdraw, deposit, and transfer behaviour is not fully implemented.
• GambleGames/slots.lua, GambleGames/roulette.lua, and GambleGames/csgoCaseUnboxing.lua are empty placeholders.
• Passwords and account checksums are stored in plain text, so this should be treated as an in-game project rather than a secure banking system.
