2.0.0-alpha.8

New features

• Updated to 1.21.5
• Added CrafterWindow, MerchantWindow, StonecutterWindow
• Added methods to change/update items/slot elements in GUIs based on the ingredient key that was used in the structure
• Content lists slots can now be changed after GUI creation
• Items can now have bundle select handlers (triggered when scrolling through a bundle and when the cursor leaves the bundle item)
• GUI-embedded inventories can now handle bundle interactions
• Inventories can now define a custom iteration order that is used for methods like addItem
• Windows can now have a "fallback window", which is a window that will be opened if the previous window was closed by the player (by pressing ESC or E). Unlike opening a window in a close handler, this will carry the cursor item stack over to the new window.

Changes

• Reworked animations. Animations can now be created via Animation.builder() and consist of 5 components:
  1. Slot filter: Defines which slots are part of the animation.
  2. Slot selector: Selects the slots that are shown in each frame.
  3. Intermediary generator: Creates intermediary SlotElements that are displayed before the slots pop in.
  4. Show handler: Called when slot(s) are shown, for example to play a sound effect.
  5. Finish handler: Called when the animation is finished.
• All windows are now packet-based
  • This should resolve #84 and #107
  • Click and PlayerUpdateReason no longer contain the Bukkit event / other information predicted by Bukkit, as no click event is actually fired.
  • There is no longer a difference between "single" and "split" windows. Instead, all windows are now what was previously considered a split window, with the bottom GUI defaulting to a ReferencingInventory that references the player inventory.
• GUI-embedded ReferencingInventories now automatically notify windows when the referenced contents change
• Reworked CartographyWindow
• Replacing the open window will now carry the cursor item stack to the new window
• Window close handlers now receive a close reason
• Renamed builder factory functions to be more consistent. If there is only a single builder available, the function is now named .builder (for example in AnvilWindow.builder()). Specialized builder factory functions are prefixed by their specialty (e.g. PagedGui.itemsBuilder())
• Updated the naming of some methods in PagedGui / ScrollGui
• Removed superfluous methods in PagedGui and ScrollGui, such as hasPreviousPage or goForward
• Replaced supplier-based GUI/window state with Property / MutableProperty, which are supposed to serve as an adapter interface for such data structures.
• invui-kotlin: Removed provider-combining overloads

Fixes

• Reverted GUI-/inventory slot element suppliers to the old looping behavior. This is required for cases where a GUI builder's build method is called multiple times.
• Fixed an issue where the GUI background would not work for non-nested GUIs
• Fixed an issue where Inventory#collectSimilar would not take from full stacks
