MBuild

🆕 Added

Brush System (15 types)

• Generative: /brush sphere, /brush cylinder
• Terrain: /brush smooth, /brush erode, /brush melt, /brush raise, /brush lower, /brush flatten, /brush cliff
• Environmental: /brush snow, /brush gravity
• Stylistic: /brush paint, /brush scatter, /brush splatter, /brush overlay
• Management: /brush info, /brush unbind, /brush list
• Mechanics:
  • Brushes are bound per-item using PersistentDataContainer (persists across relogs)
  • Item lore auto-updated to show current brush type, radius, pattern, mask
  • Right-click on block or in air triggers brush
  • Per-player 100ms cooldown prevents double-fires
  • All brush operations are fully undoable

Noise Engine & Masks

• Implementations: Perlin, Simplex (OpenSimplex2S), Voronoi, Worley, Ridged, FBM (pure Java, zero dependencies)
• Global Mask: /gmask <mask|reset|off> (persistent, combines with local masks using AND logic, clears on quit)
• Noise Masks: Syntax noise(type,scale[,octaves])>threshold (works in all commands)

New Commands

• Generation: /sphere, /cyl, /pyramid, /line
• Modification: /replace, /walls, /ceil, /hollow, /smooth, /drain, /terrace, /erode, /overgrow, /rubble, /crumble
• Transform: /stack, /move, /rotate, /flip, /copy, /paste [-a]
• Selection/Utility: /selinfo, /selexpand, /selcontract, /count, /distr

Core Systems

• Internationalization: Full multilingual system (lang/en.yml, lang/fr.yml)
• Configuration: MBuildConfig (history size, block limits, language)
• Undo/Redo: Multi-level per player using Deque stacks (redo clears on new action)
• Pattern/Mask API: Weighted random mixes (30%stone,70%dirt), #surface, #solid, #liquid, !block support
• Technical: BaseCommand abstract system, Direction enum with me support, OperationUtil timing/limit helpers

🔄 Changed

• Rotation: Now supports any angle (45°, 135°, etc.) via nearest-neighbor interpolation
• Masks: Updated with #floor type, ; OR operator, and %N random percentage
• Management: SelectionManager migrated to Map<UUID, …> to prevent memory leaks
• Undo System: Completely rewritten from single Undo object to Deque<HistoryEntry>
• UX: Tab completion made context-aware; added aliases /br and /wand
• Metadata: plugin.yml updated to api-version: 1.18 (1.18→1.21 compatibility)

🗑️ Removed

• Old Undo.java and single-action undo system
