Supplementaries adds many animated and functional decorations and redstone blocks that fit in well with vanilla minecraft.

Supplementaries Minecraft Mod



Wind vane:

cool decoration blocks that swings depending on the weather and will give off a redstone signal depending if it's raining (1) or thundering (2). If you're wondering the scribbles on its base are the cardinal directions initials in the enchanting table language.

Wind Vane

Hanging sign:

very cool decorative item perfect for you medieval build or for labeling. You can write text or hand an item on it: It's animated and it will swing an entity passes through it! You can also display maps on them. Can be placed both on a wall or under a block. Will connect and can be placed on fences and walls.

Hanging signs


Most complicated block added so far, they can do a lot: they can store 4 buckets or 12 bottles of any vanilla liquids (like honey, milk, lava, potions, soups, dragon breath or xp) as well as and fireflies. It basically functions as a shulker box for liquids or a rudimental tank. You can now also store cookies and fishes! Not compatible with the forge fluid system and with other fluid mods, meant to complement vanilla only.

Jars can also store small mobs like slimes, slimes and bees. To catch vexes and endermites you'll have to use tinted ones. Shift right click to place a mob jar instead of releasing its mob.



when turned on it will starts spilling on the ground the inventory of up to two blocks behind it. If you place it in front of a water block (cauldron, water/waterlogged), it will start dripping water particles and will display a cosmetic only falling water effect that depends on the liquid color of what's behind it. You can use it to pour liquids to and from jars. Since it can extract items from the side of a block it enables some sort of automation not possible with vanilla. It will also interact with other blocks like hives and concrete powder. Its water color will depend on what's behind it.


Spring Launcher:

I've added this one because it's been 5 years and slime blocks + pistons are still inconsistent and bugged as hell. This block does one thing, it push entities about twice as far as the vanilla setup(when it works). It also works as a spring and will proper you upwards if you fall on it with enough force provided it's extended. Try it out, it's really fun!

Spring Launcher

Notice Board:

Simple block that lets you insert a book it it and will display the content of its first page. You can interact with it with hoppers meaning you can make some interesting contraptions that display a specified text dynamically. Note that the algorithm that displays the first page tries to fill as much space as possible resizing the font accordingly so if it doesn't display as you would want try adding spaces. You can now use it to display maps and cycle trough them with hoppers to make some sort of tv!

Notice Board

Speaker Block:

Use it to send a message to all players around either trough chat or narrator. Rename it "" in an anvil to get rid of its name at the start of each message.

Speaker Block

Wall lanterns:

You can now place vanilla lanterns on a wall| Should work with modded ones too like "skinned lantern" mod.

Wall lanterns

Sign post:

you can place up to two of them on any fence block. They will function just like a normal sign. You can shift right click to reverse its orientation. You can also use a compass to make them point to a lodestone or spawn point position.
Sign Posts

Turn Table:

when powered it will keep rotating the block that it's facing (if it's a directional block of course) or the entities that are standing (meaning it has to face up) on it. For a single rotation provide him a short pulse. You can toggle it to reverse the direction.

Turn Table


used for growing crops without the need of a water source block. Now you can grow them even in the nether and you won't have to worry about animals trampling your crops!


Clock Block:

I'm sure I don't have to explain this one. I'll just say that you can read the hour with a comparator (hello automation!). If right clicked will display the time in chat.

Clock Block


will keep refreshing fire blocks that are closer to it (so you can keep them alive indefinitely without netherrack but you will still need to protect from rain) and will push entities that are up to 5 blocks from it. Will also speed up furnaces and campfires that are next to it. Pulsing speed depends on power received and everything it does will be more intense the more power it has.



basically more powerful version of a lever that lets you choose between 16 different power states as you turn it


Redstone Illuminator:

simple variable light source that stays on by default and decreases its light level depending on the power it receives

Redstone Illuminator


acts as an item display and doubles as a column. Try placing one on top of the other! It also displays the item custom name.



a 1.17 ready fancy new light source. You can place them on the floor, wall or even ceiling



a passive mob that spawns in plains, roofed forest and swamps. They do nothing except flying around. you can put them in a jar by right clicking one with it. Will only be present at night and will despawn during the day.

FirefliesFirefly jar


aren't you tired of spamming those ugly torches everywhere? Well now you have a more elegant alternative to light up your medieval builds! They act as a torch upgraded and can be lit and unlit just like campfire: try throwing water bottles on them of light them up with flaming arrows . Additionally their solid iron mount prevents when from accidentally being washed away by water


Item Shelves:

They act sort of like item frames. Place them on chests to label them and you still be able to click through them, unlike its vanilla cunterpart. They also are a block and not an entity and that means they should overall cause less lag.

Cog block:

Still a work in progress. A 1.17 ready item that will act as a form of upgraded redstone. Pretty intutive to use, just power one and it will power adiacent cog blocks up to 14 blocks away, just like redstone. Pretty op at the moment and might need some tweaks like reducing its radius. Texture is a placeholder

Flag(s): Still a work in progress and not in creative menu yet. They will be just a decorative item. Currently I've added a green one with 3 experimental animations on the 3 graphics settings. Feedback needed.

Read me!

TLDR: If you would like to help in any shape or form, like proving screenshots, tweaking config values, provide feedback or suggestion contact me.

Please if you find any bugs, inconsistency or oversight, as small as they may be, be sure to report them here or send me the crash report in private.

Other feedback on animations, textures and so on is also welcome.

I'm starting to add a lot of configs to tweak a bunch of parameters like animations and so on. Feel free to try them out and If you find a configuration that looks better than mine please send it to me so I'll add as a new default.

I'm also open to suggestions, If you have any idea that I think will fit with the theme with them mod post them here and I'll consider adding them.

Finally if you would like to help please contact me. I could use somebody that knows how to make custom sounds.

Also if you can get some nicer screenshots or thumbnail for the mod page be my guest :D

Also I just looked into it and basically making and maintaining a fabric version would mean basically rewriting the whole mod, so please don't ask for a fabric version unless you know an easy way to at least translate the mappings.

Pleas don't ask to port to older versions. maintaining this one already takes up alot of time and I'm non interested in supporting older obsolete versions.

Update: I've been releasing updates like crazy couple last months and I think I'll take a break for a while. I have a lot of suggestions and ideas on my plate so don't worry, more will come in due time.

Possible future additions:

(ideas about their implementation are welcome)
  • laser block, flags: they are already partially added but I got stuck with them and who know when they will be finishes
  • display case
  • label
  • fishing net
  • launcher rail
  • blackboard
  • plate
  • block activator
  • bamboo spikes
  • gauge
  • door mat
  • bird cage
  • cogs
  • some kind of teleportation block
  • xp collector block: I don't want to do something boring like a retextured hopper so I was thinking of some sort of nether artifact or something like that. Creative ideas and names are very welcome
  • rework a lot of textures, add many sounds (help needed here)


You might notice that I've included a couple of blocks similar to the ones added from other mods. I wanted to point out that everything here, assets included was made by myself (of mojang of course) and I only took some inspirations and ideas which I really liked from other mods that, unfortunately, aren't available for 1.15.

as far as I remember there are more mobs that just that. you can find an extensive list of them in client configs. But generally yes the newer fish from the mod are missing (even if they should still get the default 2d generic fish texture).

I haven't made those tho, they were made on the mod compat channel on my discord by some contributors there so if you would want to contribute yourself by providing those textures you can join the discord.
