# Custom Ore Gem - Developer Guide for Agents
This repository is a Minecraft **NeoForge 1.21.1** mod created with **MCreator**. Agents must follow these strict guidelines to ensure build stability and code preservation.
## 1. Build & Test Commands
Use the Gradle wrapper for all operations. Ensure you are using Java 21 (NeoForge 1.21.1 requirement).
- **Build Mod:**
```bash
./gradlew build
```
- Generates the mod JAR in `build/libs/`.
- Always run this after making changes to verify compilation.
- **Run Client:**
```bash
./gradlew runClient
```
- **Run Server:**
```bash
./gradlew runServer
```
- **Run Data Generation:**
```bash
./gradlew runData
```
- This generates resources (blockstates, models, loot tables) into `src/generated/resources`.
- **Run All Tests:**
```bash
./gradlew test
```
- **Run Single Test Class:**
```bash
./gradlew test --tests "net.mcreator.customoregen.OresCommandTest"
```
- **Run Single Test Method:**
```bash
./gradlew test --tests "net.mcreator.customoregen.OresCommandTest.testCommandRegistration_ShouldRegisterOresCommand"
```
- **Clean Project:**
```bash
./gradlew clean
```
## 2. MCreator & Code Preservation
**CRITICAL:** This project is partially generated by MCreator.
- **Generated Files:** Many files in `src/main/java` are regenerated on every build or MCreator export.
- **User Code Blocks:** You **MUST** only edit code within designated user code blocks in these files.
```java
// Start of user code block [block_name]
// ... YOUR CODE HERE ...
// End of user code block [block_name]
```
- If a file does not have these blocks, assume it is **UNSAFE** to edit unless you created it yourself.
- **Safe Files:**
- Files strictly created by you (e.g., in `src/test/java`).
- New utility classes or event handlers not managed by MCreator.
- **Do NOT** directly modify the following unless inside a user block:
- `CustomOreGenModBlocks.java`
- `CustomOreGenModItems.java`
- `CustomOreGenModTabs.java`
- Any file in `net.mcreator.customoregen.procedures` (unless explicitly safe).
## 3. Code Style & Conventions
### Formatting
- **Indentation:**
- **Source Code (`src/main`):** Use **TABS** (default MCreator style).
- **Tests (`src/test`):** Use **4 SPACES** (typical for JUnit tests).
- **Consistency:** Always check the current file's indentation before editing.
- **Encoding:** UTF-8.
### Naming
- **Classes:** PascalCase (e.g., `CustomOreGenMod`).
- **Methods:** camelCase (e.g., `queueServerWork`).
- **Constants:** UPPER_SNAKE_CASE (e.g., `MODID`, `COLD_BIOMES_TAG`).
- **Fields:** camelCase (e.g., `workQueue`, `oreGenConfig`).
- **Packages:** `net.mcreator.customoregen` (lowercase).
### Imports
- Group imports in this specific order:
1. Java/Standard Libraries (`java.*`, `javax.*`)
2. Third-party Libraries (e.g., `org.apache.logging.log4j.*`)
3. Minecraft/NeoForge (`net.minecraft.*`, `net.neoforged.*`)
4. Project Classes (`net.mcreator.customoregen.*`)
- Avoid `import *` unless there are many imports from the same package (e.g., `java.util.*` is acceptable if heavily used, but explicit imports are preferred for clarity).
### Logging
- Use `LogManager.getLogger(Class.class)` for loggers.
- Field name: `LOGGER`.
- Log levels: Use `debug` for dev info, `info` for general status, `error` for exceptions.
## 4. Architecture & Patterns
- **Framework:** NeoForge 1.21.1 (Java 21).
- **Registries:** Use `DeferredRegister` for all registries (Blocks, Items, Tabs, SoundEvents).
- Example: `public static final DeferredRegister.Blocks REGISTRY = DeferredRegister.createBlocks(CustomOreGenMod.MODID);`
- **Event Bus:**
- The `@Mod` class registers the `IEventBus`.
- Use `@SubscribeEvent` for event handling.
- Event handlers often reside in `net.mcreator.customoregen.event` or static inner classes annotated with `@EventBusSubscriber`.
- **Configuration:**
- Located in `net.mcreator.customoregen.config.ModConfigs`.
- Uses `ModConfig.Type.COMMON` built with `ModConfigSpec`.
- Access configs via the public static fields (e.g., `ModConfigs.ORE_GEN.shardDiamondOreCount.get()`).
- **Commands:**
- Registered via `RegisterCommandsEvent`.
- Use Brigadier (`CommandDispatcher`, `CommandContext`).
- See `OresCommand.java` for the reference implementation.
## 5. Testing Guidelines
- **Framework:** JUnit 5 (Jupiter) + Mockito.
- **Location:** `src/test/java`.
- **Mocking Strategy:**
- Since a full Minecraft environment is not available in unit tests, you **MUST** mock Minecraft classes.
- Use `@ExtendWith(MockitoExtension.class)`.
- Mock critical classes: `@Mock ServerPlayer player`, `@Mock Level level`, `@Mock BlockPos pos`.
- Stub methods: `when(level.getBiome(pos)).thenReturn(biomeHolder);`.
- **Assertions:** Use `org.junit.jupiter.api.Assertions` (e.g., `assertEquals`, `assertDoesNotThrow`).
## 6. Common Tasks
- **Adding a New Ore:**
1. Create Block & Item (MCreator/Manual).
2. Add JSONs: Loot Table, Configured Feature, Placed Feature, Biome Modifier.
3. Register in `CustomOreGenModBlocks` and `CustomOreGenModItems`.
4. Update `OresCommand.java` lists (e.g., `COLD_ORES`, `HOT_ORES`) to make it discoverable.
5. Update `OreBreakEventHandler.java` if it has custom drops logic.
6. Add to `ModConfigs.java` for generation parameters (vein size, count, etc.).
- **Modifying Logic:**
- Check `procedures/` for game logic (often MCreator generated).
- Check `event/` for event-driven logic.
- Always verify if logic changes need a corresponding test update.
## 7. Safety & Verification
- **Backups:** If you are unsure about MCreator regeneration, backup the file before editing.
- **Verification:**
- Always run `./gradlew build` after changes to ensure no compilation errors.
- If you touch config files, ensure `ModConfigsTest` still passes.
- If you touch commands, ensure `OresCommandTest` still passes.

**Important**: Custom items like the Ore Biome Finder, Shard Diamond armor, and Paxel are registered in this protected section and will survive MCreator rebuilds.
## Event Handlers
The mod uses NeoForge's event system for ore processing:
### OreBreakEventHandler
- Listens to `BlockEvent.BreakEvent` with `@SubscribeEvent`
- Maps custom ore blocks to ore type strings (`shard_diamond`, `concentrated_coal`, `pure_golden`, etc.)
- Calls `ConfigurableOreDropsProcedure.execute()` with ore type when player breaks ore with correct tool
- Supports 10 ore types: shard_diamond, concentrated_coal, pure_golden, impure_iron, concentrated_diamond, lapis, redstone, emerald, copper
### EnchantabilityFix
- Uses `ModifyDefaultComponentsEvent` to set enchantability values on tools and armor
- Currently **commented out** - enchantability not yet applied
- When active, should set `DataComponents.ENCHANTABLE` with value 9 (tools) or 14 (armor)
## Loot Table Format
NeoForge 1.21 uses `loot_table` (singular) instead of `loot_tables` (plural):
- Location: `src/main/resources/data/custom_ore_gen/loot_table/blocks/{orename}.json`
- Includes Silk Touch support via `match_tool` condition
- Uses `random_sequence` for loot table randomization
- Example structure in `deepslatesharddiamondore.json` shows Silk Touch → drop block, otherwise drops handled by `OreBreakEventHandler`
## Vanilla Ore Removal
The mod removes vanilla ores via NeoForge biome modifiers (NOT KubeJS anymore):
- `src/main/resources/data/custom_ore_gen/neoforge/biome_modifier/remove_vanilla_ores.json`
- Uses `neoforge:remove_features` type to remove vanilla ore generation
- This replaces the old KubeJS automatic script system from Forge 1.20.1

## Enchantment Tags
The mod includes enchantment tags at `src/main/resources/data/minecraft/tags/item/enchantable/`:
- **armor.json** - Marks Shard Diamond armor pieces as enchantable
- **durability.json** - Marks tools and armor for durability enchantments
- **mining.json** - Marks pickaxes, shovels, and paxel as mining tools
- **weapon.json** - Marks axes as weapons
These tags enable proper enchantment behavior for custom items in the enchanting table and anvil.
