About this project
What does Stackable127 add?
Stackable
Stackable is a mod that increases all block stacking limits to any value for Minecraft 1.21.1+.
Why make this mod
I don't know; other mods already exist that allow for stack sizes above 64. This was more for experimentation with creating mixins and understanding Minecraft's code and modloaders a little better.
Will you update to X?
Maybe.
Will you backport to X?
Eh, not really.
There's a bug here?
I might fix bugs that are Vanilla specific, but mod compatibility is gonna be kinda hard to do
Mod support?
This mod should be compatible with most other mods. Some blocks will limit their storage size to 64, but they shouldn't crash. Most of my mixins to the code surround editing the interface that all inventory mods should implement to begin with, so if they call the stack size from that interface, they should receive the appropriate value.
