Minecraft 1.19.2 Forge模组开发 02.物品栏+方块+物品

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 reference
    public static final String MOD_ID = "re8joymod"; //修改为你的模组名称
    // Directly reference a slf4j logger
    private static final Logger LOGGER = LogUtils.getLogger();

	//物品栏声明
    public static final CreativeModeTab TUTORIAL_TAB = new CreativeModeTab(MOD_ID) {
        @Override
        public 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 modloading
        bus.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 in
        MinecraftForge.EVENT_BUS.register(this);
    }

    private void setup(final FMLCommonSetupEvent event)
    {

    }

    private void commonSetup(final FMLCommonSetupEvent event)
    {
        // Some common setup code
        LOGGER.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
    {
        @SubscribeEvent
        public 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 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 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:

Minecraft 1.19.2 Forge模组开发 02.物品栏+方块+物品_第1张图片

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"
}

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"
		}
	}
}

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"
	}
}

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"
	}
}

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
