What does Stackfinity do?

Stackfinity allows admins to adjust the maximum stack size for individual items or entire item groups. This lets you flexibly shape your server balancing, economy, and gameplay.

Features

Individual stack sizes for single items
Support for item groups via patterns (Regex)
Simple in-game command for direct adjustment
Changes are applied immediately
Automatic saving of all changes
Secure input with validation of invalid values

Important Notes

Item ID must match the registered name exactly.
After changes, a server restart is recommended to ensure clean synchronization of all inventories.

The 3 Variants at a Glance

There are three ways to configure stack sizes:

Variant	Timing	Method	Permanently Saved
Individual Items (`ItemIds`)	On server start	Edit configuration file	Yes
Item Groups (`Patterns`)	On server start	Regex pattern in configuration file	Yes
In-game Command	While server is running	`/stacksize item_id amount`	Yes

1. Individual Items via `ItemIds`

Set fixed stack sizes for specific items:

{
  "ItemIds": {
    "iron_ingot": 64,
    "diamond": 16,
    "emerald": 32
  }
}

2. Multiple Items via `Patterns`

Use regex patterns to adjust entire item groups at once. This is especially useful when many similar items should have the same stack size.

Instead of listing each item individually, you can capture multiple matching items with a single pattern.

{
  "Patterns": {
    ".*_ore": 64,
    ".*_ingot": 32,
    ".*_gem": 16
  }
}

Pattern Examples

Pattern	Description
`.*_ore`	All items ending in `_ore`, e.g., `iron_ore`, `gold_ore`, or `diamond_ore`
`.*_ingot`	All items ending in `_ingot`, e.g., `iron_ingot`, `gold_ingot`, or `copper_ingot`
`sword_.*`	All items starting with `sword_`
`.*_block`	All items ending in `_block`

3. Runtime Changes

Adjust stack sizes directly during server operation:

/stacksize iron_ingot 64
/stacksize diamond 16

Changes are applied immediately and automatically saved to the configuration file.

Command

Use the following command to change the stack size of an item:

/stacksize item_id amount

Examples

/stacksize iron_ingot 64
/stacksize diamond 16
/stacksize dirt 32

item_id is the ID of the item.
amount is the new maximum stack size and must be a positive integer.
