About this Mod

Stacks Are Stacks

This mod is rather simple, just like many before it. It makes all items (except tools) stackable up to 64. This includes items like shulker boxes, beds, water buckets, potions, enchanted books and totems of dying as well as any modded items.

Due to how simple and compact the mod actually is, there is little to no configuration involved. Just install, launch and like that. All your items will stack up to 64 now, what happens when you remove the mod? Well nothing, those stacks should still remain stacked until you touch them. (Just don't throw them into the world, because Mojang hates that)

Requirements

Requires Fabric API & oωo (owo-lib)

Of course a mod like this isn't without it's issues, due to how Minecraft was written a lot of the Item handling is hardcoded meaning something like emptying a Water Bucket doesn't bother to check if it's a stack or not, it just gives you an Empty Bucket resulting in losing that whole stack but don't worry. I've gone through and applied fixes to a lot of the common issues typically faced with having stacked items however I most likely didn't find all the possible issues so if you find one, feel free to open an issue

I will of course try add compatibility for any mods that require it, though if that mod is changing vanilla code it is more up to them to not follow the poor example and account for stacks of any size

A lot of the above is being improved and changed with 1.20.5 and above with NBT removal and Component Usage but still some are lacking fixes

tl;dr: Minecraft code = bad, if you find issues with stacks disappearing please open an issue

Use at your own risk

Known Issues

  • When Bucketing an Axolotl you'll get a ghost bucket
    • This is completely fine and is caused by the way the data is saved to the bucket, simply clicking on it in your inventory will cause it to vanish.
    • It's not fixable without making heavy changes to the Axolotl Entity

Feel free to use this mod in other modpacks but keep the download within the Modrinth Ecosystem and do not reupload
