Stackables

Stackables

Make some non-stackable items stackable. Works for potions, soups, cakes, enchanted books, full buckets, boats, minecarts, saddles, beds, music discs, goat horns, and banner patterns! Everything is configurable with sensible defaults built-in. Even includes an option to add a cooldown timer to splash potions to prevent them from being too strong!

Versions for 1.20.5 and beyond

Minecraft 1.20.5 changed how max stack size is configured for each item, making it more data-driven. Because of this, modifying the max stack size dynamically as you modify the configuration file is VERY unstable. I am still working on an alternative, but I fear that starting with 1.20.5, this mod might not be feasible anymore without completely doing away with the dynamic configuration aspect.

A note about bugs and mod compatibility

Be aware that simply changing the maximum stack size for items is not enough. If you know how to program and take a peek at the source for this mod, you'll understand immediately that vanilla Minecraft (and a lot of mods by extension) makes a lot of assumptions about the maximum stack size of items.

For example, when you drink a milk bucket, the vanilla code finishes off by simply replacing the item(s) in that slot with an empty bucket, without checking the actual contents. If I only increase the max stack size of milk buckets, drinking from a stack will wipe out the whole stack. Therefore I have to also hook into vanilla code where it handles drinking milk and replace it with custom logic to give you an empty bucket instead.

As I said above, these kinds of quirks are everywhere in the vanilla code and in a lot of mods. I have tried to find all the examples of this in vanilla code, but if you find any that I missed please report it on GitHub and I will do my best to fix it ASAP. In some cases, the bug is actually a result of another mod modifying the same points in code, which makes fixing the bug much more difficult. Sometimes, like with the commonly reported Easy Anvils, the mods are simply incompatible unless that mod's author writes their newly-added mod code in the same way my fixes are written, where stack size and maximum stack size can always be any number.

Tags

As of version 2.0.0, Stackables functions via tags! Every max stack size is now controlled exclusively through the new tags. If you come across mods that add items you feel should be included in a particular category, you can add them to the appropriate tag with a data pack!

Configuration

You can configure the behavior of the mod from the stackables.toml file within your config folder. If you have ModMenu installed, you can also access the configuration through the UI in ModMenu's mod list (only affects single player worlds)!
