今天是1024程序员日，我们尝试在1.19.2的模组中实现物品栏、方块和物品
1.在项目主类Main.java中添加物品栏声明，同时将物品和方块的类进行注册：
Main.java
package com.joy187.re8joymod;import com.joy187.re8joymod.init.BlockInit;
import com.joy187.re8joymod.init.ItemInit;
import com.mojang.logging.LogUtils;
import net.minecraft.world.item.CreativeModeTab;
import net.minecraft.world.item.ItemStack;
import net.minecraft.world.level.block.Blocks;
import net.minecraftforge.common.MinecraftForge;
import net.minecraftforge.eventbus.api.IEventBus;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.event.lifecycle.FMLClientSetupEvent;
import net.minecraftforge.fml.event.lifecycle.FMLCommonSetupEvent;
import net.minecraftforge.fml.javafmlmod.FMLJavaModLoadingContext;
import net.minecraftforge.registries.ForgeRegistries;
import org.slf4j.Logger;// The value here should match an entry in the META-INF/mods.toml file
@Mod(Main.MOD_ID)
public class Main
{// Define mod id in a common place for everything to referencepublic static final String MOD_ID = "re8joymod"; //修改为你的模组名称// Directly reference a slf4j loggerprivate static final Logger LOGGER = LogUtils.getLogger();//物品栏声明public static final CreativeModeTab TUTORIAL_TAB = new CreativeModeTab(MOD_ID) {@Overridepublic ItemStack makeIcon() {//这个是物品栏的图标使用哪个物品来展示return new ItemStack(BlockInit.EXAMPLE_BLOCK.get());}};public Main(){IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus();// Register the commonSetup method for modloadingbus.addListener(this::commonSetup);bus.addListener(this::setup);//添加物品、方块的注册ItemInit.ITEMS.register(bus);BlockInit.BLOCKS.register(bus);// Register ourselves for server and other game events we are interested inMinecraftForge.EVENT_BUS.register(this);}private void setup(final FMLCommonSetupEvent event){}private void commonSetup(final FMLCommonSetupEvent event){// Some common setup codeLOGGER.info("HELLO FROM COMMON SETUP");LOGGER.info("DIRT BLOCK >> {}", ForgeRegistries.BLOCKS.getKey(Blocks.DIRT));}// You can use EventBusSubscriber to automatically register all static methods in the class annotated with @SubscribeEvent@Mod.EventBusSubscriber(modid = MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD)public static class ClientModEvents{@SubscribeEventpublic static void onClientSetup(FMLClientSetupEvent event){}}
}
2.Java包中新建init包，init包中新建一个我们的物品类ItemInit ：
ItemInit.java
package com.joy187.re8joymod.init;import com.joy187.re8joymod.Main;
import net.minecraft.world.item.Item;
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.ForgeRegistries;
import net.minecraftforge.registries.RegistryObject;import java.util.function.Supplier;public class ItemInit {public static final DeferredRegister<Item> ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, Main.MOD_ID);//我们的第一个物品public static final RegistryObject<Item> LEI = register("lei",() -> new Item(new Item.Properties().tab(Main.TUTORIAL_TAB)));//第二个物品//public static final RegistryObject<Item> FAKE = register("fake",// () -> new Item(new Item.Properties().tab(Main.TUTORIAL_TAB)));private static <T extends Item> RegistryObject<T> register(final String name, final Supplier<T> item) {return ITEMS.register(name, item);}
}
3.在init包中新建一个我们的方块类BlockInit:
BlockInit.java
package com.joy187.re8joymod.init;import com.joy187.re8joymod.Main;
import net.minecraft.core.BlockPos;
import net.minecraft.world.entity.EntityType;
import net.minecraft.world.item.BlockItem;
import net.minecraft.world.item.CreativeModeTab;
import net.minecraft.world.item.DyeColor;
import net.minecraft.world.item.Item;
import net.minecraft.world.level.BlockGetter;
import net.minecraft.world.level.block.Block;
import net.minecraft.world.level.block.SoundType;
import net.minecraft.world.level.block.StainedGlassBlock;
import net.minecraft.world.level.block.state.BlockBehaviour;
import net.minecraft.world.level.block.state.BlockState;
import net.minecraft.world.level.material.Material;
import net.minecraft.world.level.material.MaterialColor;
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.ForgeRegistries;
import net.minecraftforge.registries.RegistryObject;import java.util.function.Function;
import java.util.function.Supplier;public class BlockInit {public static DeferredRegister<Block> BLOCKS = DeferredRegister.create(ForgeRegistries.BLOCKS, Main.MOD_ID);public static final DeferredRegister<Item> ITEMS = ItemInit.ITEMS;//第一个方块 of(方块和什么类似,方块颜色) strength(挖掘时长(越大时间越长),防爆等级(越大越防爆)) sound(挖方块的声音) public static final RegistryObject<Block> EXAMPLE_BLOCK = register("example_block",() -> new Block(BlockBehaviour.Properties.of(Material.METAL, MaterialColor.COLOR_PURPLE).strength(5f, 6f).sound(SoundType.METAL).requiresCorrectToolForDrops()),object -> () -> new BlockItem(object.get(), new Item.Properties().tab(Main.TUTORIAL_TAB)));//第二个方块//public static final RegistryObject<Block> HOT_BLOCK = register("hot_block",// () -> new Block(BlockBehaviour.Properties.of(Material.METAL, MaterialColor.COLOR_PURPLE).strength(5f, 6f)// .sound(SoundType.METAL).requiresCorrectToolForDrops()),// object -> () -> new BlockItem(object.get(), new Item.Properties().tab(Main.TUTORIAL_TAB)));private static <T extends Block> RegistryObject<T> registerBlock(final String name,final Supplier<? extends T> block) {return BLOCKS.register(name, block);}private static <T extends Block> RegistryObject<T> register(final String name, final Supplier<? extends T> block,Function<RegistryObject<T>, Supplier<? extends Item>> item) {RegistryObject<T> obj = registerBlock(name, block);ITEMS.register(name, item.apply(obj));return obj;}private static <T extends Block> RegistryObject<T> registerBlock(String name, Supplier<T> block, CreativeModeTab tab) {RegistryObject<T> toReturn = BLOCKS.register(name, block);registerBlockItem(name, toReturn, tab);return toReturn;}private static <T extends Block> RegistryObject<Item> registerBlockItem(String name, RegistryObject<T> block,CreativeModeTab tab) {return ItemInit.ITEMS.register(name, () -> new BlockItem(block.get(),new Item.Properties().tab(tab)));}private static <T extends Block> RegistryObject<T> registerBlockWithoutBlockItem(String name, Supplier<T> block) {return BLOCKS.register(name, block);}public static Supplier<Block> createStainedGlassFromColor(DyeColor color) {return () -> new StainedGlassBlock(color, BlockBehaviour.Properties.of(Material.GLASS, color).strength(0.3F).sound(SoundType.GLASS).noOcclusion().isValidSpawn(BlockInit::never).isRedstoneConductor(BlockInit::never).isSuffocating(BlockInit::never).isViewBlocking(BlockInit::never));}public static boolean always(BlockState state, BlockGetter reader, BlockPos pos) {return true;}public static boolean never(BlockState state, BlockGetter reader, BlockPos pos) {return false;}public static boolean always(BlockState state, BlockGetter reader, BlockPos pos, EntityType<?> entityType) {return true;}public static boolean never(BlockState state, BlockGetter reader, BlockPos pos, EntityType<?> entityType) {return false;}
}
4.代码部分结束，进入资源包制作环节：
在resources/assets/lang/你的模组名称包中的en_us.json中添加英文名称：
en_us.json
{"item.re8joymod.lei":"125 Lei","block.re8joymod.example_block": "Umbrella Block","itemGroup.re8joymod": "RE8 Item"
}
在zh_cn.json中添加中文名称：
zh_cn.json
{"item.re8joymod.lei":"125 物品","block.re8joymod.example_block": "方块","itemGroup.re8joymod": "RE8 物品栏"
}
在blockstates包中新建一个我们的方块文件，指明其模型位置：
example_block.json
{"variants": {"": {"model": "re8joymod:block/example_block"}}
}
在models/block中添加方块的模型文件：
example_block.json
{"parent": "block/cube_all","textures": {"all": "re8joymod:block/example_block"}
}
在models/item中添加方块和物品的手持模型文件：
添加方块的手持模型文件：
example_block.json
{"parent": "re8joymod:block/example_block"
}
添加物品的手持模型文件：
lei.json
{"parent": "item/generated","textures": {"layer0": "re8joymod:item/lei"}
}
在textures/block中添加方块的贴图，在textures/item中添加物品的贴图：
5.在resources/data文件夹下新建2个文件夹，一个叫minecraft，另一个是你的模组名称(以re8joymod为例)
在minecraft文件夹中新建 -> tags文件夹 -> tags包中新建blocks文件夹 -> blocks包中新建mineable文件夹 ->在mineable中新建 pickaxe.json(定义方块是否可挖掘)
pickaxe.json
{"replace": false,"values": ["re8joymod:example_block" //这里面的方块都是可以被挖掘的]
}
在re8joymod中新建loot_tables文件夹 -> 在loot_tables中新建blocks文件夹 -> 在blocks文件夹中新建 方块名.json(名称与BlockInit.java中你自定义的方块名称保持一致)
example_block.json(挖掉之后方块的掉落物)
{"type": "minecraft:block","pools": [{"rolls": 1.0,"entries": [{"type": "minecraft:item","name": "re8joymod:example_block" //掉落物格式:模组名称:物品、方块的名称，原版默认是minecraft:xxx}]}]
}
6.保存所有文件，刷新项目，启动游戏
