Animal Pen

## [0.3.0] - Individual Animals & Interface Rework ### Highlights - Animal Pens now retain every animal as an individual instead of representing the entire pen with one shared NBT template - Sheep of different colors retain their own color and produce the correct wool when sheared or killed - The Animal Pen information screen has been redesigned into a compact, coherent, responsive interface ### Added - **Individual Animal Storage** - Stores complete NBT, health, age, appearance, name, ownership, and variant data for every animal in a pen - Preserves differently colored sheep and other same-type animal variants in one pen - Includes migration support for existing count-based Animal Pen saves - Uses compact client update data so full NBT for all 64 animals is not sent with every visual update - **Per-Animal Sheep Drops** - Shearing evaluates every stored adult sheep individually - Mixed-color pens produce the corresponding wool colors rather than copying the front sheep's color - Wool of matching colors is merged into stacks before being given to the player - Baby sheep are excluded from shearing - **Improved Capture Safety** - Prevents players from capturing another player's owned animals - Prevents capture while an animal is mounted, carrying passengers, or leashed - Keeps the animal in the world if the captured item cannot be inserted or spawned safely - Validates captured entity data before deposit or release - Prevents releasing animals into obstructed spaces - **Passive Resource Collection** - Empty-hand right-click now collects stored passive resources - Resource changes synchronize to the Animal Pen screen - Resource icons in the screen include counts and hover tooltips ### Changed - **Breeding Rework** - Breeding now feeds at most two pairs (2-4 animals) per cycle - Baby capacity is reserved when food is consumed, preventing deposits from filling those slots mid-cycle - Full pens no longer consume breeding food without producing offspring - Breeding creates real offspring NBT from individual parents instead of incrementing a shared adult count - Stored babies continue growing inside the pen - Individual vanilla age and post-breeding cooldown values continue ticking while stored - Breeding timing now uses level game time for consistent server/client progress and unload behavior - **Combat Rework** - Sneak-attack targets the front animal while ordinary attacks remain available for breaking the pen - Sneak-attacking an occupied pen no longer progresses block mining - Damage is calculated from the player's attack-damage attribute and attack strength - Loot tables receive the actual killed animal and its individual NBT state - **Tool Interactions** - Bucket interactions dispatch directly to chickens or milkable animals without contradictory messages - Buckets, bottles, and bowls now use vanilla-style filled-container handling - Creative-mode interactions no longer consume captured animals or empty containers - Milking, stewing, shearing, and brushing respect the targeted animal's adult state - Tool failures are treated as handled pen interactions and no longer fall through to unrelated item behavior - **Animal Pen Screen** - Replaced the oversized split overlay with one centered, bounded panel - Added consistent preview, pen status, breeding, and stored-resource cards - Improved spacing, alignment, typography hierarchy, progress bars, and footer controls - Added responsive sizing for different window and GUI scales - Reduced the animal preview size and refreshes it when the front animal changes - Moved all screen text to localization keys - **Captured Animal Rendering** - Captured items are cached by entity type and individual NBT instead of entity type alone - Different sheep colors and other variants now render correctly in inventories, hands, item frames, and as dropped items - Added a bounded render cache that is cleared when changing worlds ### Fixed - Same-type animals losing or duplicating names, colors, owners, ages, health, and variant data - Damaged animals using their current health as their permanent maximum health - Extracting a damaged animal restoring health from an unrelated shared template - Stale breeding state carrying across extraction, death, or replacement with another species - Breeding progress and passive resources appearing stale in the client screen - Passive honey and other generated resources being inaccessible without breaking the pen - Chicken egg collection showing an incorrect "cannot milk" message first - Entity loot conditions evaluating against the attacking player instead of the killed animal - Client and server disagreeing about whether arbitrary held-item interactions succeeded - Client-only ghost resource drops when an Animal Pen was removed - Partial inventory insertion potentially duplicating passive resource drops - Item removal utilities removing incorrect quantities across multiple stacks - Captured Animal items reusing the first-rendered animal's appearance - Renderer shadow state remaining disabled after a rendering exception ### Technical - Replaced deprecated item client-extension initialization with `RegisterClientExtensionsEvent` - Added per-animal save serialization with backward-compatible legacy migration - Added compact front-animal serialization for block entity update packets - Centralized entity validation and safer NBT copying - Improved render entity cleanup when caches, screens, block entities, or worlds are removed
