Welcome to SkQuery 4.1, this is the complete SkQuery story, adding all elements from the SkQuery 4 (pre1 and pre2) (Except Advancements and Npcs (Ok it's hard to maintain NMS)).

Added:

• Added the ability for Tab Completions to work regardless of their capitalization. (Thanks PanGargamel #12)
• Added Expression to get characters at indices from strings:
  • Code (Text):

    1. char[acter][s] at [index] %numbers% (within|in) %strings%
• Added inventory name event expression:
  • Code (Text):

    1. inventory name
  • Example:
    Code (Text):

    1. on inventory click:
    2.     broadcast "%inventory name%"
• Added WorldBorder expressions. Type name: worldborder
  • World border center:
    • Code (Text):

      1. center of [world[ ]border[s]] %worldborders%
      2.  
      3. %worldborders%'[s] [world[ ]border[s]] center
• World border time:
  • Code (Text):

    1. warning time of [world[ ]border[s]] %worldborders%
    2.  
    3. %worldborders%'[s] [world[ ]border[s]] warning time
• World border distance:
  • Code (Text):

    1. warning distance of [world[ ]border[s]] %worldborders%
    2.  
    3. %worldborders%'[s] [world[ ]border[s]] warning distance
• World border damage amount:
  • Code (Text):

    1. damage [amount] of [world[ ]border[s]] %worldborders%
    2.  
    3. %worldborders%'[s] [world[ ]border[s]] damage [amount]
• World border damage buffer:
  • Code (Text):

    1. [damage] buffer of [world[ ]border[s]] %worldborders%
    2.  
    3. %worldborders%'[s] [world[ ]border[s]] [damage] buffer
• World border size:
  • Code (Text):

    1. (size|diameter) [over [a [(time|period) of]] %-timespan%] of [world[ ]border[s]] %worldborders%
    2.  
    3. %worldborders%'[s] [world[ ]border[s]] (size|diameter) [over [a [(time|period) of]] %-timespan%]
• Added WorldBorder locations within condition:
  • Code (Text):

    1. %locations% is [with]in [world[ ]border[s]] %worldborder%
    2.  
    3. %locations% (isn't|is not) [with]in [world[ ]border[s]] %worldborder%
• Added trail projectile:
  • Can only be used within the on shoot event
  • Data's aren't supported because the VisualEffect isn't accessible without parsing an expression to addons, and I haven't made a particle library yet.
  • Code (Text):

    1. trail projectile with %particles%

Fixed:

• Fixed "Entity has potioneffect" condition to support multiples:
  • Before:
    
    Code (Text):

    1. %livingentity% (has|have) %potioneffecttype%
    2.  
    3. %livingentities% does(n't| not) (has|have) %potioneffecttype%
    Before
  • After:
    
    Code (Text):

    1. %livingentities% (has|have) [potion [effect]] %potioneffecttypes%
    2.  
    3. %livingentities% (doesn't|does not|do not|don't) have [potion [effect]] %potioneffecttypes%

• Fixed Divisible condition to support multiples:
  • Before:
    
    Code (Text):

    1. %number% is divisible by %number%
    2.  
    3. %number% is not divisible by %number%
  • After:
    
    
    Code (Text):

    1. %numbers% (is|are) divisible by %number%
    2.  
    3. %number% (isn't|is not|aren't|are not) divisible by %number%

• Fixed Prime condition to support multiples:
  • Before:
    
    Code (Text):

    1. %number% is [a] prime [number]
    2.  
    3. %number% %number% is not [a] prime [number]
  • After:
    
    Code (Text):

    1. %numbers% (is|are) [a] prime [number]
    2.  
    3. %numbers% (isn't|is not|aren't|are not) [a] prime [number]

• Fixed a syntax mistake where "not" in:
  
  Code (Text):

  1. %itemtype% (isn't|is not) not [a] block
  • should be:
    
    Code (Text):

    1. %itemtype% (isn't|is not) [a] block
  • My guess is that this has always existed in SkQuery.

• Fixed inventory name in 1.13+ with some changes to how you are going to be able to get it.
  • So in 1.13+ Spigot removed the ability to get the title of inventories, unless they're a container or an InventoryView.
  • Meaning SkQuery can only implement those ways, so the new ways to get the inventory name are the event value "inventory name" within the inventory click event.
  • Example:
    
    Code (Text):

    1. on inventory click:
    2.     event-inventory is not player's inventory
    3.     inventory name is "example"
    4.     cancel event
  • The other way it's implemented is if the inventory has a holder aka a container being a block:
    
    Code (Text):

    1. on block break:
    2.     if inventory name of inventory of event-block is "example":
    3.         cancel event
  • Keep in mind doing name of %inventories% will go to Skript in which the newest Skript versions just outright removed the ability to grab the name.
    • So be advised it's not SkQuery not working if you don't add inventory name before.
  • Using the inventory name expression in versions lower than <1.13 will act normal prior to this update.
  • This should still work assuming it's the event-inventory in an inventory click event as well:
    
    Code (Text):

    1. on inventory click:
    2.     event-inventory is not player's inventory
    3.     broadcast inventory name
    4.     broadcast inventory name of event-inventory
  • It's a bad way to check inventories against their name, so as an alternative you can add a player to a variable list:
    
    Code (Text):

    1. on script unload:
    2.     delete {inventories::temp::*}
    3.  
    4. command /example:
    5.     trigger:
    6.         set {_inventory} to chest with 2 rows named "example"
    7.         set slots 4 and 13 of {_inventory} to light green stained glass pane named "&bSkQuery" with lore "&2&lLine 1" and "&6Line 2"
    8.         add player to {inventories::temp::example-opened::*}
    9.         open {_inventory} to player
    10.  
    11. on inventory click:
    12.     event-inventory is not player's inventory
    13.     broadcast inventory name
    14.     broadcast inventory name of event-inventory
    15.     {inventories::temp::example-opened::*} contains player
    16.     cancel event
    17.     if index of clicked slot is 4 or 13:
    18.         broadcast "&bYou clicked the SkQuery example."
    19.  
    20. on inventory close:
    21.     remove player from {inventories::temp::example-opened::*}
    22.  
    23. on disconnect:
    24.     remove player from {inventories::temp::example-opened::*}

Hope you enjoyed this semi-big update. Let us know if you find any bugs at https://github.com/SkQuery/SkQuery/issues

If you're a developer and wanna contribute to SkQuery you can do so at our repo https://github.com/SkQuery/SkQuery/pulls

Version naming is 4.1 as 4 already exists and this includes all of v4 which wasn't that much to be honest. Most of it is in vanilla Skript now.

Enjoy.
