在项目根目录下创建creativetab包新建TabReg.javaimport craftedegg.rbw.item.ItemReg; import java.util.Iterator; import java.util.Random; import net.minecraft.core.registries.Registries; import net.minecraft.network.chat.Component; import net.minecraft.world.item.CreativeModeTab; import net.minecraft.world.item.CreativeModeTabs; import net.minecraft.world.item.Item; import net.minecraftforge.registries.DeferredRegister; import net.minecraftforge.registries.RegistryObject; public class TabReg { public static final DeferredRegisterCreativeModeTab CREATIVE_MODE_TABDeferredRegister.create(Registries.CREATIVE_MODE_TAB, rbw); public static final RegistryObjectCreativeModeTab MOD_TAB CREATIVE_MODE_TAB.register(tab, () - CreativeModeTab.builder().withTabsBefore(CreativeModeTabs.COMBAT).title(Component.translatable(creativetab.rbw.tab)).icon(() - ((Item)((RegistryObject)ItemReg.rbwItems.get((new Random()).nextInt(ItemReg.rbwItems.size()))).get()).getDefaultInstance()).displayItems((parameters, output) - { output.accept(ItemReg.BOMB_BENCH_ITEM.get()); output.accept(ItemReg.GUARANTEE.get()); Iterator var2 ItemReg.rbwItems.iterator(); while(var2.hasNext()) { RegistryObjectItem item (RegistryObject)var2.next(); output.accept(item.get());} }).build());; }也是直接用循环直接注册数组里的物品到物品栏在主类的构造方法里加上TabReg.CREATIVE_MODE_TAB.register(modEventBus);注册到事件总线。接下来讲解如何注册实体新建entity包新建EntityReg.javapackage craftedegg.rbw.entity; import craftedegg.rbw.Main; import net.minecraft.world.entity.EntityType; import net.minecraft.world.entity.MobCategory; import net.minecraftforge.registries.DeferredRegister; import net.minecraftforge.registries.ForgeRegistries; import net.minecraftforge.registries.RegistryObject; public class EntityReg { public static final DeferredRegisterEntityType?
