Jacks Server Side Tweaks

A collection of gameplay features that are not required on a client.

All features can be configured via the /jsst command.

Features

All features can be enabled or disabled using /jsst <feature> (enable/disable).

Item Editor

By far the largest feature, this provides an easy-to-use, extensive interface for modifying items.

Currently supports the following:

  • Names, including multi-component texts and custom gradient support
  • Lores, with the same features
  • Enchantment, with tooltip fix for levels > 10
  • Potions (Drinkable, Splash, Lingering, Tipped Arrows, Suspicious Stew)
  • Attribute Modifiers
  • Container Locks
  • Banner/Shields, with support for PlanetMinecraft's Banner Editor.
  • Durability Editor, including unbreakable modifiers
  • Book Author Editor
  • Book Unsigner
  • Head Owner Changer
  • Leather Armour Colour Editor
  • Firework & Firework Star Editors
  • Armour Trim Editor

and more as ideas come in.

To begin, run the command /jsst itemEditor hand to change the item in your hand, or .. itemEditor item <item> to use a template.

This feature will only show editors possibly usable with the given item.

Labels

Enchantments, Potion Effects and Attribute Modifiers have been given custom labels to help see them at a glance; however I can not provide defaults to every modded enchantment out there. If you want to add your own (either in your mod or a datapack), you can create a corresponding JSON file under data/jsst/item_editor_labels/<category>.json.

In this JSON file, there is a single JSON object with another JSON object under the key values. In this values object, there should be a list of ID: LabelDefinition pairs; you can find the ID by enabling enabledDevTools and browsing said menu.

LabelDefinition is defined as either a minecraft item ID such as minecraft:diamond_pickaxe, or a full ItemStack JSON which you can get from an existing stack by the enabledDevTools-only Stack JSON Printer.

You can replace the entire vanilla set by adding replace: true alongside the values tag at the top level.

For a better explained example, see JSST's base files.

Config

Option Description Default Valid Options
enabledDevTools Enable dev-specific editors. true true, false

Portable Crafting

Lets you use crafting tables by right-clicking with them.

Valid items to check are contained in the jsst:items/crafting_tables tag, which can be extended using data packs or the Command Defined Datapack feature below.

Config

Option Description Default Valid Options
sneakOnly Whether players need to sneak to use crafting tables as items. false true, false

World Container Names

A collection of named containers with their names floating above, along with a diamond sword above a barrel

Adds floating labels above containers from either the container name or item count.

Uses the new Display Entities from 23w06a.

To give a name to a container, rename it in an anvil. You can use the format [item:<ITEM_STACK>] to display an item instead, using the same syntax as the /give command. Examples:

  • [item:minecraft:golden_apple]
  • [item:potion{Potion:"night_vision"}]

If you give a container the name [max-count], the item displayed will update to the highest-count item in the container every time it is opened.

Admin

To clean up if you ever remove JSST, you can run the following command to remove lingering display entities:

/kill @e[tag=jsst_world_container_name]

Config

Option Description Default Valid Options
facingMode How labels should face the player. CENTER CENTER, VERTICAL
labelRangeMultiplier Multiplier for the distance labels are shown. 1 [0.25, 4]

Display Items

A collection of colour wool on pedestals that do not despawn.

Lets you make items for display that don't despawn by renaming them to [display] in an anvil.

Useful for shops or showcases. Plays a chime sound if a display item is successfully made.

Warning: This does not prevent the item from being destroyed in other ways, such as cactus, lava, /kill, cleanup plugins, or being moved with hoppers or water.

Admin

To 'take ownership' of nearby items, run the following command:

/execute as @e[type=item,tag=jsst_display_item,distance=..5] run data modify entity @s Owner set from entity @p UUID

Config

Option Description Default Valid Options
ownerPickupOnly Should only the player who dropped the item be able to pick it back up. true true, false
operatorOnly Should only server operators be allowed to create display items? Does not apply in single player. Recommended to enable ownerPickupOnly if this is true. false true, false

Command Defined Datapack

Lets you create and manage a datapack folder via in-game commands.

Currently, only supports tags. Designed to help configure mods game features using tags such as minecraft:enderman_holdable, or jsst:crafting_tables, or just creating tags for your server easier.

/jsst cdd save - Manually saves a copy of the current datapack in-memory. Should not be required in most cases as other commands that modify the pack call this directly.

Tags

See also: Tag JSON Format

Base command: /jsst cdd tag <registry>

<registry> defines which registry the tags should be looked up through. For example, you'll want minecraft:item to modify item tags or minecraft:block for block tags.

  • .. listTags [filter] - Lists all tags that are registered for this registry.
  • .. list <tag> - Lists all elements in a given tag. This is after tags have been 'flattened' i.e. tags referenced by other tags are not shown.
  • .. add <tag> value <element> [isOptional] - Adds an element to a <tag> in the datapack.
  • .. add <tag> tag <newTag> [isOptional] - Adds a reference to <newTag> in <tag> in the datapack.
  • .. remove <tag> <element> - Removes an element from <tag> in the datapack. This does not let you remove items from tags defined elsewhere; use setReplace below to overwrite them.
  • .. setReplace <tag> <shouldReplace> - Marks <tag> to overwrite other tags with the same name.
Example (Adding nether stars to the crafting table list for Portable Crafting above)
  1. /jsst cdd tag minecraft:item add jsst:crafting_tables value minecraft:nether_star
  2. /datapack enable "file/jsstCDD" on first generation
  3. /reload

Banner Writing

Easily write sentences with a stack of blank banners and a command.

Running a command and writing 'kingdom' effortlessly.

To start, simply use the command /jsst bannerWriter start <text>. This will add a tag to the banners you are holding, which lets the mod know what to replace.

Uses the letters and numbers from https://www.gamergeeks.net/apps/minecraft/banners/.

Supported letters:

abcdefghijklmnopqrstuvwxyz0123456789 .,+-*/'"=!:

Sapling Replanter

Sapling items try to plant themselves instead of de-spawning. Tries to space them out, and includes support for dark oak saplings.

Example of replanted saplings, spaced out by a block.

Config

Option Description Default Valid Options
spacingEnabled Should saplings try to space themself out? true true, false
minimumDistance Minimum blocks between saplings. Requires spacingEnabled. Dark Oak has it's own handling. 1 [1, 3]
searchRange Horizontal distance that saplings search for a valid position. Vertically, always checks layer above and below. 3 [1, 4]
maxPerStack Maximum number of saplings to plant per dropped stack; the rest are discarded. 5 [1, 64]

Beacon Range Multiplier

Beacons can have a multiplier to their range added.

A beacon granting it's effect well over the vanilla 20 block range

For reference, various ranges for beacons are:

Level Vanilla Range in Blocks 1.5x (mod default) 4x 8x
1 20 30 80 160
2 30 45 120 240
3 40 60 160 320
4 50 75 200 400

Config
