Undo & Redo

Press Ctrl+Z to immediately undo the previous operation, making it much more convenient to develop redstone machines!
For more information, please check our wiki page.

All blocks, block entities and entities are undoable.
Undo is available only if that change is caused by a player, for example, placing blocks and commands.

RVC

WIP

RVC, Redstone Version Control, machine history and diff analysis based on git.

RVC can upload your machines to GitHub if you have bound your GitHub account at https://redenmc.com.
So, RVC machines can be shared easily with others, all you need to do is to copy a GitHub link.
RVC supports subregions and submodules, so you can use other people's work in your own creations.

RVC: Selection

Almost done

RVC brings a totally new way of selecting blocks that is much easier.
You can hold a blaze rod in your hand, then left click to select a group of blocks, and right click to ignore.

RVC Package Manager

Planing

RVC Package Manager is a package manager for redstone machines, it can help you:

  • Manage the dependencies of your machines
  • Update the dependencies to the latest version
  • Publish your machines to the RVC repository
  • Allow other people to use your machines with ease
  • Give credit to everyone who contributes to your machines

It uses git submodules to manage the dependencies, so you can use other people's work in your own creations.

RVC: Activity

Planing

When you link your GitHub account, reden can automatically track your activities on GitHub,
such as creating a new repository, pushing a new commit, and creating a new release.
And your activities will be sent to your followers in the game, so people can get notified when their dependencies are
updated.

RVC: Reference

WIP

For many fields such as storage tech, people will make some slices that,
for example, each slice can filter a single type of item.

However, when you want to test them, you have to stack them together, which is very inconvenient.
RVC Reference can help you to place a "reference" of a slice, once you finished your slice,
you can press a hotkey, and the reference will be updated to the latest version of the slice.
Happy debugging!

RDebugger

WIP

Micro-timing analysis and simulation: block update breakpoints (NC, PP, CU, BE), BED debugger, step-by-step update, step-by-step tick, update reset

RVC with RDebugger

Planning

R-Debugger can be used with RVC, you can configure a flow to debug your machine,
and the flow will be saved in the RVC history.
A flow might look like this, for example:

[steps]
Use: button at 0 0 0
Use: lever  at 1 3 5
Fill-Area:  name=area1  from=0 0 0  to=10 10 10  with=stone
Wait: 10 ticks

[check]
Require: block at 0 0 0   is stone
Require: block at 1 3 5   is lever
Has-Item:chest at 0 0 0   has 1 diamond

Our Wishes

Provide a one-stop working environment for redstone machine developers and become the best redstone debugging and teaching tool.

Other Features

  • Command Hotkeys: Super Right -> runCommand use masa-style hotkeys to run commands
  • Force Sync Entity Pos: Micro Ticking -> toggleForceEntityPosSync force sync entity pos to clients, maybe useful when you freeze the game
  • No Time Out: General -> noTimeout disable timeout on clients, if you are debugging the server, you probably need this
  • Item Shadowing Detector: carpet redenDebuggerItemShadow Detect if there are shadowed items in the inventory, wip, it will support to disable operations that may break the link in the future
  • Structure Block Hotkey: Ctrl+S to save and Ctrl+L to load for you last interacted struct block.

Bug fixes

  • carpet fixInvisibleShadowingItems: fix invisible shadowing item entity, for more information, check Igna's video

Reden server crashes on startup – what to do?

Reden officially supports fabric, quilt for Minecraft 1.21.8, 1.21.7, 1.21.6. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Reden – how to optimize performance?
