HoR XLib

• VS 1.22 Compatibility
  Full migration to VS 1.22 APIs. All breaking changes resolved: Entity.Pos property conversion, ResolvedItemStack capitalization, PascalCase property access patterns, and GridRecipe/IRecipeBase signature updates.
• Current HoR Progression Stack
  Version alignment for the current HoR mod stack. This is the library layer used by HoR-XSkills and HoR-XSkills-Addon for skills, abilities, syncing, and status effects on 1.22.
• Maintained compatibility build
  The original mod has not been updated for 1.22, this fork ensures continued compatibility for the HoR modpack and any dependent mods.

The core skill/leveling engine powering all HoR progression systems

• Skill System
  Define skills with custom names, display names, groups, and experience equations. Each skill supports quadratic or logarithmic XP curves with configurable base values and class-specific multipliers. Skills can be grouped in the GUI and hidden from specific players.
• Ability System
  Each skill contains multiple abilities with tiered progression (1-N tiers). Abilities have minimum level requirements, descriptions with value interpolation, and requirements that can be combined with AND/OR/NOT logic. Ability types include StatAbility (auto-apply stats), TraitAbility (toggle traits), and StatsAbility (multiple stat modifiers).
• Requirement System
  Flexible requirement types: SkillRequirement (another skill at level X), ClassRequirement (specific VS class), DaytimeRequirement (time of day), KnowledgeRequirement (unlocked knowledge), ExclusiveAbilityRequirement (mutually exclusive perks), and LimitationRequirement (global perk limits). Custom requirement types can be registered by mods.
• Player Skill Sets
  Per-player persistent skill data stored via VS save system. Tracks current level, experience, earned abilities, and ability tiers for every skill. Supports save/load with backward compatibility for older save formats.
• Configuration System
  JSON-driven skill and ability definitions loaded from assets/[modid]/skills/. Supports custom skill configs (CustomSkillConfig), experience equation delegates, and global configuration via config files.
• Skill Dialog GUI
  Built-in skill dialog showing all skills and abilities with tier progress, requirements, and tooltips. Ability tooltips display interpolated values for each tier. Supports grouping and custom skill ordering.
• Skill Books
  ItemSkillBook implementation for granting XP via craftable/lootable books.
• Client/Server Sync
  XLevelingClient and XLevelingServer implementations handle network synchronization. Skill changes on the server propagate to clients via command packages (CommandPackage), experience packages (ExperiencePackage), and knowledge packages (KnowledgePackage).
