织物的 Minecraft 编码错误:加载“myfirstmod"提供的入口点“main"条目时出现异常 [英] Minecraft coding error with fabric: Exception while loading entries for entrypoint 'main' provided by 'myfirstmod'

问题描述

package net.my.first.mod;

import net.fabricmc.api.ModInitializer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemGroup;
import net.minecraft.util.Identifier;
import net.minecraft.util.registry.Registry;
import net.minecraft.block.Block;

public class MyFirstMod implements ModInitializer {

    public static final Item FABRIC_ITEM = new FabricItem(new Item.Settings().group(ItemGroup.MISC), null);

    public static final Block FABRIC_BLOCK = new FabricBlock();

    @Override
    public void onInitialize() {
        Registry.register(Registry.ITEM, new Identifier("myfirstmod", "fabric_item"), FABRIC_ITEM);
        Registry.register(Registry.BLOCK, new Identifier("myfirstmod", "fabric_block"), FABRIC_BLOCK);
    }

}

package net.my.first.mod;

import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.ActionResult;
import net.minecraft.util.Hand;
import net.minecraft.util.TypedActionResult;
import net.minecraft.world.World;

public class FabricItem extends Item {

    public FabricItem(Settings settings, Settings item$Settings_1) {
        super(item$Settings_1);

    }

    @Override
    public TypedActionResult<ItemStack> use(World world, PlayerEntity playerEntity, Hand hand) {
        return new TypedActionResult<ItemStack>(ActionResult.SUCCESS, playerEntity.getStackInHand(hand));
    }

}

每当我尝试运行我的代码时，我都会遇到崩溃.我正在使用 Visual Studio 代码，但我不明白为什么会发生这种情况，我什至尝试重新编码整个过程.这是我得到的错误:

I keep running into a crash whenever I try to run my code. I am using visual studio code and I don't understand why this is happening I have even tried re-coding the whole thing. Here's the error I get:

推荐答案

你扔掉了真正的Settings，而是传递了null！改变这个:

You're throwing away the real Settings you have and passing null instead! Change this:

    public FabricItem(Settings settings, Settings item$Settings_1) {
        super(item$Settings_1);

    }

为此:

    public FabricItem(Settings settings, Settings item$Settings_1) {
        super(settings);

    }

您还可以从该定义和您在 MyFirstMod 中调用它的位置中删除第二个参数，现在您没有将它用于任何事情.

You can also get rid of the second parameter both from that definition and from where you call it in MyFirstMod, now that you're not using it for anything.
