Stack Tags

Stack Tags lets you control item stack sizes using data packs. Place items into one of several tags to set their exact max stack size.

What it does

• Adds item tags that set exact max stack sizes: stack_tags:stackable_to_1, stack_tags:stackable_to_2, stack_tags:stackable_to_4, stack_tags:stackable_to_8, stack_tags:stackable_to_16, stack_tags:stackable_to_32, stack_tags:stackable_to_64.
• If an item is present in multiple tags, the largest value wins.
• Values are clamped to 64.

How to use

Add your items to the desired tag(s) via a data pack:

data/stack_tags/tags/items/stackable_to_16.json
{
  "replace": false,
  "values": [
    "minecraft:lava_bucket",
    "minecraft:water_bucket"
  ]
}

Or replace the default behavior of the mod to set up your custom max stack sizes:

data/stack_tags/tags/items/stackable_to_16.json
{
  "replace": true,
  "values": [
    "minecraft:golden_apple",
    "minecraft:enchanted_golden_apple"
  ]
}

You can create similar files for stackable_to_1, 2, 4, 8, 32, and 64.
