Upgrade Guide

v2.2

Core Improvements:

• Multi-threading Support: The entire system has been refactored for thread-safety, ensuring robust and stable operation in projects utilizing multi-threaded environments.
• New Asset Loading System: Introduced three distinct methods for loading icons and custom data objects associated with your items, providing greater flexibility in memory management and asset delivery:
  Direct Reference:Description: The data object (e.g., Texture2D for an icon, GameObject for a model) is directly assigned and stored within the item's data.
  Pros: Simplest and most straightforward setup. The object is immediately available once the item data is loaded.
  Cons: All directly referenced objects will be loaded into memory at game launch, potentially increasing initial loading times. This memory cannot be easily freed as long as the item data remains in memory.
  
  Resources Folder:Description: The object is loaded from a Resources folder at runtime, specifically when a script attempts to access it.
  Pros: Offers more flexible memory management as you can explicitly load assets only when needed and release them using Item.ReleaseLoadedAsset(). This method generally uses less initial memory at launch.
  Setup: Requires you to provide the relative path to the object within any Resources folder (e.g., "Icons/MySwordIcon").
  
  Custom Loader (AssetLoader):Description: The object is loaded via the AssetLoader component. By default, this component is configured to load assets from AssetBundles.
  Flexibility: You can extend this functionality by inheriting from the AssetLoader class to create your own custom loading script (e.g., for Addressables, web requests, or other custom asset management systems).
  Integration: Attach your custom loader script to the InventoryEngine prefab to replace the default AssetLoader component.
  

Modding & Editor Enhancements:

• JSON Data Import/Export: Added new inspector buttons and API calls for the ItemManager component, allowing you to easily export and import Item, Attribute, and Enchantment settings in JSON format. This greatly simplifies external data management and modding workflows.Important Note for Modding: If you intend for modders to easily modify or swap out icon or custom data, it is strongly recommended not to use the "Direct Reference" loading method. Direct references embed asset data, making external modification or swapping difficult. Instead, consider using the "Resources Folder" or "Custom Loader" methods for moddable assets.
  
• Improved Editor UI Performance: Significant optimizations have been made to the editor user interface, resulting in a smoother and more responsive experience, particularly when managing large inventories.

New Features & Refinements:

• Merchant Specific Pricing: Introduced a 'Specific Price Multiplier' feature to Merchant components, allowing you to define unique price adjustments for individual items on a per-merchant basis.
• Enchantments Pool: Added enchantments pool in LootPack settings, so you can speicify which enchantments the items from each lootpack can randomly get.
• Modular Attribute System: The Attribute class has been refactored into a separate, modular component, enhancing reusability and future compatibility with other packages, including our upcoming "CombatCore."

v2.11 (Small patch)

Bug Fix: Drag any equipment back to an empty inventory slot throws an error.

Bug Fix: Custom data mistakenly linked when copying item's data.

Bug Fix: The HP value of the player and monster are not correctly displayed in the example scene.

Improvements: Added support to make all interface works when Time.timeScale==0. (Game Pause)

Demo Improvements: Added stun effect.

Notes:

• Version 2.1 significantly enhances the usability of v2.0's new features.
• The Included demo scene will allow the user to easily learn how to use the package.
• The detailed example empowers developers to quickly implement core RPG mechanics.

v2.0

Major New Features & Enhancements:

• Randomized Item Stats:Items now generate with randomized, non-static stats, perfect for creating dynamic loot and enhancing rogue-like gameplay.
  Configure stat ranges and unlock chances for endless item variations.
  
• Item Cool-Down Functionality:Implement cool-down periods for items, affecting usage across all inventory locations (Action Bar, Inventory, Equipment).
  Adds strategic depth to item usage.

  Provides flexible control over character stats via the "Base Stats" of InventoryHolder component.
  
• Enhanced Stat Display Customization:Expanded customization options for stat presentation, allowing for tailored UI/UX.
  
• Item Use/Equip Restrictions:Implement attribute-based restrictions for item usage and equipment.
  Example: Require a character level of 5 or higher to equip an item.
  
• Custom Item Data List:Attach any data format (AudioClip, Prefab, Texture, etc.) to items.
  Enables advanced item behaviors and interactions.
  

Notes:

• Version 2.0 introduces significant gameplay enhancements, including randomized item stats, cool-down functionality, and attribute-based restrictions.
• The added Custom Data List allows for massive expansion of what kinds of data can be tied to inventory items.
• The enhanced stat customization and character stat binding offer greater flexibility in UI/UX design.

v1.91

• Player Stats UI Prefab:Added a pre-built Stats interface prefab for easy integration.
  Location: Assets\SoftKitty\InventoryEngine\Prefabs\Ui\PlayerStats.prefab
  
• Filter-Aware Drag/Split Restrictions:Enhanced filter functionality to prevent drag/split actions on items that do not match the current filter (visually represented by half-transparent items).
  
• InventoryHolder Item List Expansion/Shrinkage:Implemented "Expand All" and "Shrink All" buttons for the InventoryHolder component's item list, streamlining workflow.

• Corrected an issue where splitting non-deletable items would result in item duplication.
• Fixed a bug that caused the merchant interface to malfunction when the player possessed fewer than three currency types.
• Resolved an issue preventing NPCs from equipping items when a Player InventoryHolder was absent from the scene.
