Skript 2.16.0

Supports: Paper 1.21.4 - 26.2

Today, we're excited to be releasing Skript 2.16! This release, while a bit smaller, includes a handful of new features to work with as we continue to lay the groundwork for even more exciting features later this year.

In accordance with supporting the last 18 months of Minecraft updates, Skript 2.16.0 supports Minecraft 1.21.4 to 26.2. Newer versions may also work but were not tested at time of release. Paper is required.

Below, you can familiarize yourself with the changes. Additionally, by clicking here, you can view the list of new syntax on our documentation site. As always, report any issues to our issues page!

Per our release model, we plan to release 2.16.1 on August 1st. We may release additional emergency patch releases before then should the need arise.

Happy Skripting!

Release Highlights

Boss Bars

At last, support has been added for creating and interacting with boss bars. There is full support for a bar's title, progress, color, and more:

:::applescript
on join:
    set {_bar} to a white boss bar titled "<green>Welcome %player%!":
        set the progress of event-boss bar to 50%
        set the style of event-boss bar to 6 notches
        make event-boss bar darken the sky
    add the player to the viewers of {_bar}
    wait 5 seconds
    remove the player from the viewers of {_bar}

It is also possible to create keyed bars that persist through restarts and are available in the /bossbar command:

:::applescript
command /create-ad <text> <color> <text>:
    trigger:
        set {_ad} to a keyed boss bar with id arg 1
        set the color of {_ad} to arg 2
        set the title of {_ad} to arg 3

every 30 seconds:
    # hide any other ads
    remove all players from the viewers of all keyed boss bars
    # show an ad
    set {_bar} to a random boss bar out of all keyed boss bars
    add all players to the viewers of {_bar}

The ability to interact with the boss bar of actual bosses is available too:

:::applescript
on spawn of wither:
    set the title of the boss bar of the event-entity to "<red>Angry Wither"

Stored Enchantments

A 'stored enchantments' expression has been added for working with enchanted books. This enables the creation of enchanted books that can be applied onto items.

Here's an example for creating a book to apply to a sword:

:::applescript
command /godbook:
    trigger:
        set {_item} to minecraft:enchanted_book
        add mending to stored enchants of {_item} # adds mending 1
        add knockback 12 to stored enchants of {_item}
        add fire aspect 3 to stored enchants of {_item}
        give {_item} to player

Text Component Resolution

A 'resolved component' expression has been added which provides support for using certain MiniMessage tags such as selector, score, and nbt.

Consider this example:

:::applescript
send formatted "My name is <selector:@s>!"

The component must be resolved with a player so that the @s selector can be identified. Simply using the syntax:

:::applescript
send formatted "My name is <selector:@s>!" resolved for player

You can get an actual input, such as My name is Njol!

Wait Section

The 'wait' effect can used as a section to delay the code within it. The code after the section will continue to run as normal, without a delay.

Consider this example:

:::applescript
broadcast "A"
wait 1 second:
    broadcast "B"
broadcast "C"

Running this would result in A and then C being broadcast, followed by B after 1 second.

⚠ Breaking Changes

• Skript's support for tree types has been significantly overhauled internally. Functionality within scripts should generally rename the same, though some names have changed.
• Note for Addon Developers: the syntax usage name has changed from structuretype to treetype.

Experimental Features

Experimental features can be used to enable syntax and other behavior on a per-script basis. Some of these features are new proposals that we are testing while others may have unsafe or complex elements that regular users may not need.

While we have tested the available experiments to the best of our ability, they are they are still in development. As a result, they are subject to change and may contain bugs. Experiments should be used at your own discretion.

Additionally, example scripts demonstrating usage of the available experiments can be found here.

Click to reveal the experiments available in this release

### Queue **Enable by adding `using queues` to your script.** A collection that removes elements whenever they are requested. This is useful for processing tasks or keeping track of things that need to happen only once. :::applescript set {queue} to a new queue of "hello" and "world" broadcast the first element of {queue} # "hello" is now removed broadcast the first element of {queue} # "world" is now removed # queue is empty :::applescript set {queue} to a new queue of all players set {player 1} to a random element out of {queue} set {player 2} to a random element out of {queue} # players 1 and 2 are guaranteed to be distinct Queues can be looped over like a regular list. ### Script Reflection **Enable by adding `using script reflection` to your script.** This feature includes: - The ability to reference a script in code. - Finding and running functions by name. - Reading configuration files and values. ### Local Variable Type Hints **Enable by adding `using type hints` to your script.** Local variable type hints enable Skript to understand what kind of values your local variables will hold at parse time. Consider the following example: :::applescript set {_a} to 5 set {_b} to "some string" ... do stuff ... set {_c} to {_a} in lowercase # oops i used the wrong variable Previously, the code above would parse without issue. However, Skript now understands that when it is used, `{_a}` could only be a number (and not a text). Thus, the code above would now error with a message about mismatched types. Please note that this feature is currently only supported by **simple local variables**. A simple local variable is one whose name does not contain any expressions: :::applescript {_var} # can use type hints {_var::%player's name%} # can't use type hints ### Runtime Error Catching **Enable by adding `using error catching` to your script.** A new `catch [run[ ]time] error[s]` section allows you to catch and suppress runtime errors within it and access them later with `[the] last caught [run[ ]time] errors`. :::applescript catch runtime errors: ... set worldborder center of {_border} to {_my unsafe location} ... if last caught runtime errors contains "Your location can't have a NaN value as one of its components": set worldborder center of {_border} to location(0, 0, 0) ### Equippable Components **Enable by adding `using equippable components` to your script.** Equippable components allows retrieving and changing the data of an item in the usage as equipment/armor. Below is an example of creating a blank equippable component, modifying it, and applying it to an item: :::applescript set {_component} to a blank equippable component: set the camera overlay to "custom_overlay" set the allowed entities to a zombie and a skeleton set the equip sound to "block.note_block.pling" set the equipped model id to "custom_model" set the shear sound to "ui.toast.in" set the equipment slot to chest slot allow event-equippable component to be damage when hurt allow event-equippable component to be dispensed allow event-equippable component to be equipped onto entities allow event-equippable component to be sheared off allow event-equippable component to swap equipment set the equippable component of {_item} to {_component} Changes can be made directly on to the existing equippable component of an item whether using the item itself or the retrieved equippable component :::applescript set the equipment slot of {_item} to helmet slot set {_component} to the equippable component of {_item} allow {_component} to swap equipment For more details about the syntax, visit [equippable component](https://docs.skriptlang.org/docs.html?search=equippable%20component) on our documentation website.
