Dupers United Addon

We will only be covering the public release of the mod in this section. Please do not ask for the private version of the addon, you will not get it. This is mostly due to the powerful exploits it holds, we do not want them to get patched. Though we'll gladly grant you access to the addon once we see some of your great contributions.

Any mod claiming to be a "leak" or a "crack" of the private release is fake! There are a lot of malicious mods (RATs) surrounding the addon, please make sure you download the real version here!

With that out of the way, let's begin!

The Dupers United Public Addon is a custom addon for Meteor Client maintained by LOLYAY. It's a collection of exploits, utilies and other things all packed up in a neat little package. We recommend everyone to install this mod due to the many useful features it has for macros.

---

Commands

This is where the addon shines. Most of the things here are designed to for macros to automate the annoying parts of exploiting.

Placeholders

These are a few placeholders you could use with the commands.

• %PLAYER% - Replaced by the player's current IGN.
  There shouldn't be much to explain here.
• %PLAYER_UUID% - Uses the player's UUID instead of the username.
  Same as %PLAYER% but it uses a string like this!
  069a79f444e94726a5befca90e38aaf5
• %INDEX% - The current number of the loop, starting at 0.
  For example if you used .foreachplayer /msg %PLAYER% You are player #%INDEX%, Player1 would recieve a You are player #0 message, Player2 would recieve a You are player #1 messgae and so on.

.foreachplayer

Runs a command/function for every player it finds!

For example you could run .foreachplayer /pay %PLAYER% 10000. That would pay every player on the server 10000.

By default the command excludes you from the loop. This can be changed in the ForEachSettings module.

Usage: .foreachplayer <command>

.repeat & .repeat-delay

Useful if you need to send the same command a few times.

For example, you could use .repeat 5 /ah, that would send the /ah command 5 times without a delay, though doing so could get you kicked from the server if you set the number too high.

That's why the .repeat-delay command exists, you can add a delay to commands that will be ran. The delay is in ms, that means using a command like .repeat 5000 5 /ah would send the /ah command 5 times, with a 5000ms (5 second) delay.

Usage: .repeat <count> <command> and .repeat-delay <ms> <times> <command>

.clickslot

Usually used in macros, allows you to click a slot in a GUI. Pretty useful for dupes that require perfect timing. Pretty much the most useful command from the whole mod if you know how to use it right.

It supports the following action types:

• Pickup (0) - A basic click on the slot.
  • Button 0 - Left mouse click
  • Button 0 (Slot -999) - Left click outside inventory (drop cursor stack)
  • Button 1 - Right mouse click
  • Button 1 (Slot -999) - Right click outside inventory (drop cursor single item)
• Quick Move (1) - The same as Shift-Clicking. Moves items instantly.
  • Button 0 - Shift + left mouse click
  • Button 1 - Shift + right mouse click (Same behavior)
• Swap (2) - Swaps the item in the selected slot with an item in your hotbar.
  • Button 0 - Numpad key 1
  • Button 1 - Numpad key 2
  • Button 2 - Numpad key 3
  • Button 3-8 - Numpad key 4-9
  • Button 9-39 - Used to allow swapping with arbitrary inventory slots. Ignored since 1.20.3.
  • Button 40 - F key, offhand swap
• Middle Click (3) - Middle click, only defined for creative players in non-player inventories.
  • Button 2 - The default, any other button gets ignored.
• Throw (4) - The same as pressing Ctrl+Q.
  • Button 0 - Q key, drop
  • Button 1 - Control + Q key, drops the stack of items
• Clone (5) - The same as middle clicking in creative mode properly, no it does not work in survival.
  • Button 0 (Slot -999) - Starting left mouse click drag
  • Button 1 - Add slot for left-mouse drag
  • Button 2 (Slot -999) - Ending left mouse click drag
  • Button 4 (Slot -999) - Starting left mouse click drag
  • Button 5 - Add slot for right mouse click drag
  • Button 6 (Slot -999) - Ending right mouse click drag
  • Button 8 (Slot -999) - Starting middle mouse drag, similar to action 3 (Middle click)
  • Button 9 - Add slot for middle mouse click drag, similar to action 3 (Middle click)
  • Button 10 (Slot -999) - Ending middle mouse click drag, similar to action 3 (Middle click)
• Pickup All (6) - The same as double clicking, used to collect all items of one type into a single stack.
  • Button 0 - Double click
  • Button 1 - Pickup all but check items in reverse order (impossible on vanilla clients)

Slot -999 is just a special "slot" that pretty much means that you're clicking outside of the inventory.

Figuring out which slot to click is pretty difficult as most GUIs in the game do it differently, that's why we recommend using our texture pack! Download it here!

Usage: .clickslot <slot> <button> <action>

.wait

Pretty useless by itself, might seem like a joke, but it's really useful when paired with macros.

The only thing the command does by default is.. wait! This could be useful when trying to execute commands in a specific order or to have specific timings between them!

Usage: .wait <ms>

Server Crashes

Just as the title says, these modules can crash the server. Pretty useful when you can't find a working dupe and instead you just want to put it down.

Bundle Crash

It works by sending a BundleItemSelected packet with an invalid slot ID (-1337).

To use it you just need to hold a bundle in your hand and toggle the module. The server should crash pretty quickly, if it doesn't, it's patched.

Server Dupes

Possibly one of the less useful parts of the mod believe it or not. Mostly because most of the working dupes don't require you to have a seperate mod just for them, and instead require something like UI-Utils. Implementing these dupes into the mod simply takes more time, and besides, they get patched even faster.

Book & Quill Dupe

It works by sending a BookUpdate packet with a reeeeeeeeeally long title, that causes the server to fail saving your player data, effectively "freezing" your inventory state.

To use it you just need to hold a writable book in your hand and toggle the module. You should get kicked, that is fine. Log back in onto the server and you should see all of your items dropped on the ground and in your inventory.

Trident Dupe

It works by charging the trident, desyncing the release packet while swapping slots. This makes the server think you still have the item while throwing it at the same time.

To use it you just need to hold a trident in your hand and toggle the module. You should automatically start throwing tridents! When you think you threw enough of them, just turn off the module and pick them up.

Shulker Dupe

We'll be honest, we have no idea why this part of the mod is still left in. It's ancient history. Even if it works, it's definitely patched on every server that decided to update in the last 2 years.

It works by sending a STOP_DESTROY_BLOCK packet while also quickly moving items from the shulker box GUI.

To use it you just need to place and open a shulker box and toggle the module. You should now see a Dupe and a Dupe All button. Click any of them and then break the shulker box with a pickaxe. The items should appear both in your inventory and on the ground.

Trade Dupe

Another module which is mostly just kept in here for the sake of preservation, this has been patched pretty much everywhere.

It works by sending an UpdateSign packet, this lets trades to complete without removing items from the player's inventory. Requires the server to have the AxTrade plugin.

To use it you just need to upen the trade menu's sign GUI and click the AxTrade Dupe or LoverFella Dupe button. If everyting worked out correctly, you should now have the items on both accounts.

Movement

Ways to move that you definitely shouldn't be able to.

Super Reach

It works by desyncing your movement packets allowing you to hit players from a mile away.

To use it you just need to toggle the module. It really is that simple.

Anti Set Server Position

It works by intercepting the PlayerPositionLook (S2C) packet, effectively telling the server "I reject your reality.".

To use it you just need to toggle the module. Again, it really is that simlpe. But again, please keep in mind that this usually doesn't work if the server has a good anticheat.

Utility

Quality of Life things that don't really make a difference when duping, but they're still pretty useful.

Version Keeper

It works by using SelectKnownPacks to get the server version and then overriding that version in the .server info command.

It seems pretty useless at first, though most servers use a common plugin called ViaVersion which lets players join on multiple Minecraft versions to the same server. But a side effect of the plugin is that it hides the true server version from the player.

Channel Keeper

It works by looking at the server Brand and PluginChannels that the client gets sent every time it logs onto the server.

Normally, when you join a server, the server only sends you what it needs you to know. Channel Keeper parses out the noise to see what's actually running.

To put it simply, all it does is just let you see the plugin channels. It's useless in most situations.

GUI Slot NBT

It works by looking at the item data and then it adds a small tooltip to the item with some info about the item.

This lets you hover over any item and instantly copy its NBT data to your clipboard. A pretty common use for this is to see if an item is "marked" or to see the items in a shulker box.
