About this Mod

CVTweaks is a collection of features designed to make playing on the Cubeville minecraft server (cubeville.org) more efficient.

CVTweaks is not affiliated with Cubeville in any way, this is an unofficial, player-made mod and is not endorsed by Cubeville

Features:

  • RegionScript - a simple scripting language that allows you to make specific regions do different actions, like showing titles, playing music, and creating basic minigames, all on the client
  • Toggle gamemode keybind - (default key is Y) lets you quickly change your Creative gamemode with the press of a key
  • Fly speed changer - use the - and + keys to increase or decrease your creative fly speed, you can also press both to reset it to the default
  • /cvwiki <search> - allows you to search for any topic on the unofficial Cubeville wiki and get a link to it
  • AutoHome - when enabled with /autohome <on/off>, it will automatically set your home in the Survival world when your health is low, to allow you to easily TP back incase you die
  • WCSafety - when toggled with /wcsafety, if you are chatting in a group chat or private message and after send a message in global, it will make you send it twice to confirm whether you want to send it in global
  • Warp Menu - (default key is H) when pressed in the Creative world, it brings up a popup which allows you to quickly type the username of any person to warp to their plot
  • /ignore <add/remove/list> - allows you to ignore players, hiding any global messages sent by them (does not hide private messages! if you're having issues with someone in your private messages, it's time to talk to staff instead)
  • Channel Toggle - you can use /group or /global to toggle on and off only chatting in your group chat or global chat channels, without you needing to type /p or /y before the message
  • Nearest Drop - you can use the command /nearestdrop [coordinates] to get the closest drop or warpable location to those coordinates
  • And more to be added later!

RegionScript

RegionScript is a custom-coded, extremely basic, scripting language which you are able to apply to regions or subzones by using a greeting message
For instance:
/rg flag AllergenX greeting !showTitle welcome to my plot | 1 | !showActionBar 1 second after wow
will show a title on the player's screen when they enter my plot, wait 1 second, and then show a message in the action bar as well

There are tons of other commands you can use

RegionScript Commands:

  • !playsong - plays sound from the url (url must be a direct link to an mp3 file!)
  • !stopall - stops all currently playing sounds from !playsong
  • !showtitle - shows a title
  • !showactionbar - shows a message in the actionbar (the space above the player's hotbar)
  • !showsubtitle - shows a subtitle
  • !gotohome - goes to the player's creative plot
  • !showtimer - shows a timer which is displayed in the player's actionbar and counts down in seconds based on the duration
  • !toggle
  • !shake <duration (in ticks)> - shakes the camera (for 1 second, the duration should be set to 20 as it is in ticks)
  • !popup - shows a popup on the player's screen with an ok button
  • And more to come!

RegionScript 2 Lua Scripting

RegionScript 2 allows you to run custom Lua scripts directly in the client. Scripts are loaded from Pastebin and run in a sandboxed environment.

Getting Started

  1. Write your Lua script and upload it to Pastebin.
  2. Get the raw link for your paste.
  3. In game, type !script to load and run your code.
  4. To reload the script after making changes, type !reloadlua.
  5. To stop all scripts and audio, type !stopall.

Your script must include a tick() function if you want code to run repeatedly 20 times per second.

Frequently Asked Questions

CVTweaks server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.8). You can switch loaders with one click in the panel.

Is CVTweaks compatible with fabric?

CVTweaks officially supports fabric for Minecraft 1.21.8. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with CVTweaks – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if CVTweaks consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
