創建自定義項組時結構實例崩潰

Question

我嘗試為我的模組制作一個自定義項目組，但當我運行代碼時，游戲立即崩潰。

面料 1.19.2

package com.end3r.cripplingteas.item;

import com.end3r.cripplingteas.CripplingTeasMod;
import com.end3r.cripplingteas.Registry.ModItems;
import net.fabricmc.fabric.api.client.itemgroup.FabricItemGroupBuilder;
import net.minecraft.item.ItemGroup;
import net.minecraft.item.ItemStack;
import net.minecraft.util.Identifier;

public class ModItemGroup {
    public static final ItemGroup CRIPPLINGTEAS = FabricItemGroupBuilder.build(
            new Identifier(CripplingTeasMod.teas, "Crippling Teas"), () -> new ItemStack(ModItems.BASIC_TEA))
            ;

}

我嘗試使用 FabricItemGroupBuilder 為我的模組編寫自定義項目組

Answer 1

您應該遵循標識符規則。 Crippling Teas無效，因為：

• 包含一個空格
• 大寫字母

實際上，標識符應該只像crippling_teas 。
