- Vanilla buckets
- Dispensers
- Lumisene bucket (Supplementaries)
- Wooden buckets (Let's Do Meadow)
Actually reloads: Changes apply when reloading datapacks (clients need to rejoin to see changes).
How to Use
- Create a datapack
- Add items to the appropriate tag in
data/tag_stack/tags/items/if you are on versions above1.21, it'd be placed indata/tag_stack/tags/item/ - Reload datapacks (
/reload) - Let players rejoin to see changes
Example tag file (data/tag_stack/tags/items/stackable_to_16.json):
{
"replace": false,

]
