"how do i make a pickaxe that destroys 3x3 area"

To make a pickaxe that destroys a 3x3 area, you can override the `mineBlock` method in your custom pickaxe class. In this method, you can get the player's facing direction and mine the blocks in a 3x3 area based on that direction. Here's an example:

```java
public class CustomPickaxe extends PickaxeItem {
    public CustomPickaxe(ToolMaterial material, int attackDamage, float attackSpeed, Item.Settings settings) {
        super(material, attackDamage, attackSpeed, settings);
    }

@Override
    public boolean mineBlock(ItemStack stack, Level world, BlockState state, BlockPos pos, LivingEntity miner) {
        if (!world.isClientSide && state.getDestroySpeed(world, pos) != 0.0F) {
            stack.hurtAndBreak(1, miner, (player) -> player.broadcastBreakEvent(EquipmentSlot.MAINHAND));

Direction facing = miner.getDirection();
            int startX = -1;
            int startY = facing == Direction.UP || facing == Direction.DOWN ? 0 : -1;
            int startZ = -1;
            int endX = 1;
            int endY = facing == Direction.UP || facing == Direction.DOWN ? 0 : 1;
            int endZ = 1;

for (int x = startX; x <= endX; x++) {
                for (int y = startY; y <= endY; y++) {
                    for (int z = startZ; z <= endZ; z++) {
                        if (x == 0 && y == 0 && z == 0) continue; // Skip the center block as it's already mined

BlockPos newPos = pos.offset(x, y, z);
                        BlockState newState = world.getBlockState(newPos);
                        if (newState.isDestroyable(world, newPos)) {
                            world.destroyBlock(newPos, true, miner);
                        }
                    }
                }
            }
        }

return true;
    }
}
```

This code will create a custom pickaxe that mines a 3x3 area based on the player's facing direction. You can register this custom pickaxe in your mod just like any other item.

"create a npc companion on minecraft You will need to customize the behavior, AI, and rendering of your NPC by overriding methods and adding components as neede make a archer"

/* To create an NPC companion that is an archer in Minecraft Forge, you will need to create a custom entity class that extends a suitable base class like Monster or PathfinderMob. You will also need to register your custom entity, create a custom renderer for it, and define its AI tasks. */

    }
}

/* Step 4: Register the custom renderer */
// In your ClientEventBusSubscriber class, add the following code in the onClientSetup method:

/* Step 5: Define AI tasks for the archer */
// In your ArcherEntity class, override the registerGoals method to add custom AI tasks
@Override

"how do i make a pickaxe that destroys 3x3 area"

To make a pickaxe that destroys a 3x3 area, you would need to override the mineBlock method in your custom pickaxe class. In this method, you would loop through the surrounding blocks and break them as well. Here's an example of how you could do this:

```java
public class CustomPickaxe extends PickaxeItem {
    // Constructor and other methods

@Override
    public boolean mineBlock(ItemStack stack, Level world, BlockState state, BlockPos pos, LivingEntity miner) {
        if (!world.isClientSide && state.getDestroySpeed(world, pos) != 0.0F) {
            stack.hurtAndBreak(1, miner, (player) -> player.broadcastBreakEvent(EquipmentSlot.MAINHAND));

// Loop through the surrounding blocks in a 3x3 area
            for (int x = -1; x <= 1; x++) {
                for (int y = -1; y <= 1; y++) {
                    for (int z = -1; z <= 1; z++) {
                        // Skip the center block, as it's already being mined
                        if (x == 0 && y == 0 && z == 0) {
                            continue;
                        }

BlockPos targetPos = pos.offset(x, y, z);
                        BlockState targetState = world.getBlockState(targetPos);

// Check if the block can be destroyed by this pickaxe
                        if (targetState.getDestroySpeed(world, targetPos) > 0.0F && this.getTier().getLevel() >= targetState.getHarvestLevel()) {
                            world.destroyBlock(targetPos, true, miner);
                        }
                    }
                }
            }
        }

return true;
    }
}
```

This code will create a custom pickaxe that mines a 3x3 area around the targeted block. Remember to register your custom pickaxe in your mod's item registry.

"mods minecraft economie avec des billets et un distributeur"

/* Pour créer un mod économique avec des billets et un distributeur dans Minecraft Forge, vous pouvez suivre les étapes ci-dessous: */

1. Créez une classe pour les billets (par exemple, MoneyItem) qui étend la classe Item:

```java
public class MoneyItem extends Item {
    public MoneyItem(Properties properties) {
        super(properties);
    }
}
```

2. Enregistrez votre nouvel élément MoneyItem dans votre classe d'initialisation d'élément (par exemple, ModItems):

```java
public static final RegistryObject<Item> MONEY_ITEM = ITEMS.register("money_item", () -> new MoneyItem(new Item.Properties().tab(ItemGroup.TAB_MISC)));
```

3. Créez une classe pour le distributeur (par exemple, MoneyDispenserBlock) qui étend la classe Block et implémente EntityBlock:

```java
public class MoneyDispenserBlock extends Block implements EntityBlock {
    public MoneyDispenserBlock(AbstractBlock.Properties properties) {
        super(properties);
    }

@Nullable
    @Override
    public BlockEntity newBlockEntity(BlockPos pos, BlockState state) {
        return TileEntityInit.MONEY_DISPENSER.get().create(pos, state);
    }
}
```

4. Enregistrez votre nouveau bloc MoneyDispenserBlock dans votre classe d'initialisation de bloc (par exemple, ModBlocks):

```java
public static final RegistryObject<Block> MONEY_DISPENSER = BLOCKS.register("money_dispenser", () -> new MoneyDispenserBlock(Block.Properties.copy(Blocks.DISPENSER)));
```

5. Créez une classe pour l'entité de bloc du distributeur (par exemple, MoneyDispenserTileEntity) qui étend la classe BlockEntity:

```java
public class MoneyDispenserTileEntity extends BlockEntity {
    public MoneyDispenserTileEntity(BlockPos pos, BlockState state) {
        super(TileEntityInit.MONEY_DISPENSER.get(), pos, state);
    }

// Ajoutez ici la logique pour gérer l'économie, les transactions, etc.
}
```

6. Enregistrez votre entité de bloc MoneyDispenserTileEntity dans votre classe d'initialisation d'entité de bloc (par exemple, TileEntityInit):

```java
public static final RegistryObject<BlockEntityType<MoneyDispenserTileEntity>> MONEY_DISPENSER = TILE_ENTITY_TYPES.register("money_dispenser", () -> BlockEntityType.Builder.of(MoneyDispenserTileEntity::new, ModBlocks.MONEY_DISPENSER.get()).build(null));
```

Ceci est un exemple de base pour créer un mod économique avec des billets et un distributeur. Vous devrez ajouter la logique pour gérer l'économie, les transactions et les interactions avec les autres éléments et blocs du jeu.

"create a npc companion on minecraft You will need to customize the behavior, AI, and rendering of your NPC by overriding methods and adding components as neede make a archer, copy and páste ready to use, and how make it work or spawn on world"

/* ScripterAI can help you get started with creating a custom NPC archer in Minecraft Forge, but providing a complete copy-paste solution is beyond the scope of this response. Here's an outline of the steps you need to take to create your custom NPC archer. */

1. Create a new custom entity class that extends LivingEntity or a specific entity class like AbstractArcher. You can use the following code as a starting point:

```java
public class CustomArcherEntity extends AbstractArcher {
    public CustomArcherEntity(EntityType<? extends AbstractArcher> entityType, Level world) {
        super(entityType, world);
    }

// Override methods and add custom behavior here
}
```

2. Register your custom entity in your mod's main class or a dedicated entity registry class:

```java
public static final EntityType<CustomArcherEntity> CUSTOM_ARCHER = EntityType.Builder
    .of(CustomArcherEntity::new, MobCategory.CREATURE)
    .sized(0.6F, 1.99F)
    .build("custom_archer");

public static void registerEntities() {
    Registry.register(Registry.ENTITY_TYPE, new ResourceLocation(MOD_ID, "custom_archer"), CUSTOM_ARCHER);
}
```

3. Create a custom renderer class for your NPC archer. This class will handle the rendering of your custom entity:

```java
public class CustomArcherRenderer extends MobRenderer<CustomArcherEntity, CustomArcherModel> {
    public CustomArcherRenderer(EntityRendererProvider.Context context) {
        super(context, new CustomArcherModel(context.bakeLayer(CustomArcherModel.LAYER_LOCATION)), 0.5f);
    }

@Override
    public ResourceLocation getTextureLocation(CustomArcherEntity entity) {
        // Return the texture location for your custom archer
        return new ResourceLocation("your_mod_id", "textures/entity/custom_archer.png");
    }
}
```

4. Register the custom renderer in your mod's client-side setup method:

```java
private void doClientStuff(final FMLClientSetupEvent event) {
    RenderingRegistry.registerEntityRenderingHandler(CUSTOM_ARCHER, CustomArcherRenderer::new);
}
```

5. Create a custom spawn egg item for your NPC archer, so you can spawn it in the world:

```java
public static final Item CUSTOM_ARCHER_SPAWN_EGG = new SpawnEggItem(CUSTOM_ARCHER, eggColor1, eggColor2, (new Item.Properties()).tab(CreativeModeTab.TAB_MISC));
```

6. Register the custom spawn egg item in your mod's item registry:

```java
public static void registerItems() {
    Registry.register(Registry.ITEM, new ResourceLocation(MOD_ID, "custom_archer_spawn_egg"), CUSTOM_ARCHER_SPAWN_EGG);
}
```

Once you've followed these steps and filled in the required custom behavior, AI, and rendering, you can use the custom spawn egg item to spawn your custom NPC archer in the world.
