This commit implements the full crafting system for Steve entities, enabling autonomous crafting of Minecraft items with recipe validation, ingredient checking, and crafting table management. ## Changes ### 1. SteveEntity (entity/SteveEntity.java) - Added ItemStackHandler inventory (36 slots, same as player) - Implemented NBT serialization for inventory persistence - Added getInventory() accessor method ### 2. InventoryHelper (util/InventoryHelper.java) - Complete implementation of inventory management utilities - Item query methods: hasItem(), getItemCount(), getInventoryFullness() - Item manipulation: addItem(), removeItem() - Tool management: findBestTool(), needsToolRepair(), hasRequiredTool() - Chest operations: findNearestChest(), transferToChest(), retrieveFromChest() - Helper methods: isInventoryFull(), getEmptySlotCount() ### 3. RecipeHelper (util/RecipeHelper.java) - Full Minecraft recipe system integration - Recipe lookup: hasRecipe(), findRecipe() - Ingredient extraction: getRequiredIngredients(), getMissingIngredients() - Crafting table detection: requiresCraftingTable() - Recursive crafting chain analysis: getFullCraftingChain() - Recipe validation: hasAllIngredients(), getRecipeResultCount() - Recipe metadata: isShapedRecipe(), getRecipeDimensions() ### 4. CraftItemAction (action/actions/CraftItemAction.java) - Complete crafting workflow implementation with 6 phases: 1. VALIDATING - Check recipe exists and ingredients available 2. FINDING_TABLE - Search for crafting table within 16 blocks 3. PLACING_TABLE - Place crafting table if not found 4. NAVIGATING_TO_TABLE - Navigate to crafting table location 5. CRAFTING - Execute crafting operations 6. COMPLETED - Finish action - Intelligent crafting table management (find, place, navigate) - Multi-quantity crafting support with progress tracking - Ingredient validation with detailed error messages - Inventory rollback on failure - Timeout handling (10 minutes max, 30s navigation) ### 5. Development Roadmap (DEVELOPMENT_ROADMAP.md) - Comprehensive 5-phase development plan - Detailed specifications for all future features - Implementation checklists and success criteria - Risk management and best practices documentation ## Features - ✅ Steve entities can now craft any Minecraft item with a recipe - ✅ Automatic ingredient checking before crafting - ✅ Intelligent crafting table finding and placement - ✅ Full inventory management (add, remove, transfer to chests) - ✅ Tool durability tracking and selection - ✅ Persistent inventory across world reloads - ✅ Support for both shaped and shapeless recipes - ✅ Multi-quantity crafting (e.g., "craft 10 sticks") - ✅ Detailed error messages for missing ingredients ## Technical Details - Uses Minecraft Forge 1.20.1 RecipeManager API - Leverages ItemStackHandler for robust inventory handling - Implements NBT serialization for data persistence - State machine pattern for crafting workflow - Comprehensive Javadoc documentation ## Testing Required Build the project locally: ```bash ./gradlew build ``` Test crafting in-game: ``` /steve spawn TestSteve /steve tell TestSteve "craft wooden_pickaxe" ``` ## Next Steps (Phase 1.2) - Implement advanced inventory management (auto-storage, sorting) - Add persistent memory system - Integrate real vector store for semantic memory - Implement async action execution --- Related to: DEVELOPMENT_ROADMAP.md Phase 1.1 Implements: Crafting System (YuvDwi#1 Priority Feature)
