找不到合适的构造函数 1.18 java mod

Question

我正在编写 Minecraft 1.18.2 模组（Forge 40.1.80）。 由于这是我正在编写的第一个 Minecraft 模组，我在该领域没有太多经验，也不知道是什么导致了这个问题。 当我尝试运行代码时，我收到此错误（4 次）：java: no suitable constructor found for Block(net.minecraft.world.level.block.state.BlockBehaviour.Properties)。 任何帮助将不胜感激。 错误出现在这里：“（）->新块（ORE_PROPERTIES <-Here”

package com.example.factorytechv0_1.startup;

import net.minecraft.resources.ResourceLocation;
import net.minecraft.world.item.BlockItem;
import net.minecraft.world.item.Item;
import net.minecraft.world.level.block.state.BlockBehaviour;
import net.minecraft.world.level.material.Material;
import net.minecraftforge.eventbus.api.IEventBus;
import net.minecraftforge.fml.javafmlmod.FMLJavaModLoadingContext;
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.ForgeRegistries;
import net.minecraftforge.registries.RegistryObject;
import org.openjdk.nashorn.internal.ir.Block;

public class Registration {
    private static final DeferredRegister<Block> BLOCKS = DeferredRegister.create((ResourceLocation) ForgeRegistries.BLOCKS, "factorytechv0_1");
    private static final DeferredRegister<Item> ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, "factorytechv0_1");
    public static void init() {
        IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus();
        BLOCKS.register(FMLJavaModLoadingContext.get().getModEventBus());
        ITEMS.register(FMLJavaModLoadingContext.get().getModEventBus());
    }

    public static final BlockBehaviour.Properties ORE_PROPERTIES = BlockBehaviour.Properties.of(Material.STONE).strength(2f);
    public static final Item.Properties ITEM_PROPERTIES = new Item.Properties().tab(ModSetup.ITEM_GROUP);
    public static final RegistryObject<Block> CHROME_ORE_OVERWORLD = BLOCKS.register("chrome_ore_overworld", () -> new Block(ORE_PROPERTIES));
    public static final RegistryObject<Item> CHROME_ORE_OVERWORLD_ITEM = fromBlock(CHROME_ORE_OVERWORLD);
    public static final RegistryObject<Block> CHROME_ORE_DEEPSLATE = BLOCKS.register("chrome_ore_deepslate", () -> new Block(ORE_PROPERTIES));
    public static final RegistryObject<Item> CHROME_ORE_DEEPSLATE_ITEM = fromBlock(CHROME_ORE_DEEPSLATE);
    public static final RegistryObject<Block> HAFNIUM_ORE_NETHER = BLOCKS.register("hafnium_ore_nether", () -> new Block(ORE_PROPERTIES));
    public static final RegistryObject<Item> HAFNIUM_ORE_NETHER_ITEM = fromBlock(HAFNIUM_ORE_NETHER);
    public static final RegistryObject<Block> TECHNETIUM_ORE_END = BLOCKS.register("technetium_ore_end", () -> new Block(ORE_PROPERTIES));
    public static final RegistryObject<Item> TECHNETIUM_ORE_END_ITEM = fromBlock(TECHNETIUM_ORE_END);

    public static <B extends Block> RegistryObject<Item> fromBlock(RegistryObject<B> block)
    {
        return ITEMS.register(block.getId().getPath(), () -> new BlockItem(block.get(), ITEM_PROPERTIES));
    }
}

这是mod的主要初始化文件（如果需要）

package com.example.factorytechv0_1;

import com.example.factorytechv0_1.startup.ClientSetup;
import com.example.factorytechv0_1.startup.ModSetup;
import com.example.factorytechv0_1.startup.Registration;
import com.mojang.logging.LogUtils;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.eventbus.api.IEventBus;
import net.minecraftforge.fml.DistExecutor;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.javafmlmod.FMLJavaModLoadingContext;
import org.slf4j.Logger;

// The value here should match an entry in the META-INF/mods.toml file
@Mod("factorytechv0_1")
public class factorytechv0_1 {

    // Directly reference a slf4j logger
    private static final Logger LOGGER = LogUtils.getLogger();

    public factorytechv0_1() {

        // Register the deferred reg
        Registration.init();

        // Register the setup method for Modloading
        IEventBus modbus = FMLJavaModLoadingContext.get().getModEventBus();
        modbus.addListener(ModSetup::init);
        DistExecutor.unsafeRunWhenOn(Dist.CLIENT, () -> () -> modbus.addListener(ClientSetup::init));
    }
}

Answer 1

我认为您可能有错误的导入，也许 intellij/eclipse 为您建议了错误的导入。

import org.openjdk.nashorn.internal.ir.Block

此导入看起来很奇怪，请将其删除并替换为以net.minecraft.world.item开头的内容。

快速查看 API 1.18.2，class 是抽象的。 如果您确实制作了一个新的，您可以从它扩展以制作一个新的或在合适的情况下依赖强制转换类型。 它似乎是一个封闭的 static class 包装器，但它有自己的方法。 但是，它确实包含 static 类，这些类只是使用它们的使用方法调用，而不是实例化新的。
