Minecraft 1.18.1、1.18.2模组开发 03.生物实体

注:1.16.5的实体教程和本文基本类似，只是一些类中的函数名称有所不同。

我们今天在1.18.1的模组中添加一个生物实体

1.新建entity文件夹 -> 文件夹中新建一个model文件夹，一个render文件夹，一个我们的生物类(以EntityRe8Dimi.java为例)

我们本次要制作一个boss类怪物，类似于凋零，具有boss血条

打开我们的blockbench -> 制作boss的3D模型 -> 导出制作好的模型

把我们的模型文件放入上面新建的model文件夹中

}

为了让我们的生物在游戏中可以显示出来，我们需要编写生物的渲染文件

在render文件夹中新建渲染类(以RenderRe8Dimi.java为例)
RenderRe8Dimi.java

package com.joy187.re8joymod.entity.render;import com.joy187.re8joymod.Main;
import com.joy187.re8joymod.entity.EntityRe8Dimi;
import com.joy187.re8joymod.entity.model.ModelRe8Dimi;
import net.minecraft.client.renderer.entity.EntityRendererProvider;
import net.minecraft.client.renderer.entity.MobRenderer;
import net.minecraft.resources.ResourceLocation;public class RenderRe8Dimi extends MobRenderer<EntityRe8Dimi, ModelRe8Dimi<EntityRe8Dimi>> {//注意这个路径，要和上面model文件中的路径保持一致public static final ResourceLocation TEXTURE = new ResourceLocation(Main.MOD_ID, "textures/entity/re8dimi.png");public RenderRe8Dimi(EntityRendererProvider.Context manager) {super(manager, new ModelRe8Dimi<>(manager.bakeLayer(ModelRe8Dimi.LAYER_LOCATION)), 0.7F);}@Overridepublic ResourceLocation getTextureLocation(EntityRe8Dimi p_110775_1_) {return TEXTURE;}
}

2.在init包中新建一个EntityInit类用于初始化我们所有的生物

EntityInit.java

package com.joy187.re8joymod.init;import com.joy187.re8joymod.Main;
import com.joy187.re8joymod.entity.EntityRe8Dimi;import net.minecraft.resources.ResourceLocation;
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 EntityInit {public static final DeferredRegister<EntityType<?>> ENTITY_TYPES = DeferredRegister.create(ForgeRegistries.ENTITIES,Main.MOD_ID);//我们的生物类型为MONSTER(怪物)，你可以定义其他类型MOB等，两个字符串要一样比如"re8dimi"public static final RegistryObject<EntityType<EntityRe8Dimi>> RE8DIMI = ENTITY_TYPES.register("re8dimi",() -> EntityType.Builder.of(EntityRe8Dimi::new, MobCategory.MONSTER).sized(0.8f,3.0f).setTrackingRange(30).build(new ResourceLocation(Main.MOD_ID, "re8dimi").toString()));//你可以往下续写
}

3.新建一个ClientModEventSubscriber类用于提交我们的渲染信息

ClientModEventSubscriber.java

package com.joy187.re8joymod;import net.minecraftforge.fml.common.Mod;import net.minecraftforge.fml.common.Mod.EventBusSubscriber;
import net.minecraftforge.fml.event.lifecycle.FMLClientSetupEvent;import com.joy187.re8joymod.entity.EntityRe8Dimi;
import com.joy187.re8joymod.entity.model.ModelRe8Dimi;
import com.joy187.re8joymod.entity.render.RenderRe8Dimi;
import com.joy187.re8joymod.init.EntityInit;import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.client.event.EntityRenderersEvent;
import net.minecraftforge.event.entity.EntityAttributeCreationEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;@Mod.EventBusSubscriber(modid = Main.MOD_ID, value = Dist.CLIENT, bus = Mod.EventBusSubscriber.Bus.MOD)
public class ClientModEventSubscriber
{//将所有的生物的皮肤贴图信息写在这个函数里，有几个写几个@SubscribeEventpublic static void onRegisterLayers(EntityRenderersEvent.RegisterLayerDefinitions event) {event.registerLayerDefinition(ModelRe8Dimi.LAYER_LOCATION, ModelRe8Dimi::createBodyLayer);}//将所有的生物的渲染信息写在这个函数里，有几个写几个@SubscribeEventpublic static void onRegisterRenderer(EntityRenderersEvent.RegisterRenderers event) {event.registerEntityRenderer(EntityInit.RE8DIMI.get(), RenderRe8Dimi::new);}//将所有的生物的属性信息写在这个函数里，有几个写几个@SubscribeEventpublic static void onAttributeCreate(EntityAttributeCreationEvent event) {event.put(EntityInit.RE8DIMI.get(), EntityRe8Dimi.prepareAttributes().build());}}

4.在Main.java中添加:

 public Main() {IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus();ItemInit.ITEMS.register(bus);BlockInit.BLOCKS.register(bus);//把生物初始化语句加入EntityInit.ENTITY_TYPES.register(bus);MinecraftForge.EVENT_BUS.register(this);}

5.在textures包下新建一个entity文件夹存放我们的生物皮肤贴图，将.png贴图放入其中:

在en_us.lang文件中添加游戏中的生物名称

"entity.re8joymod.re8dimi": "Alcina Dimitrescu",

怪物掉落物:

在resources\data\re8joymod\loot_tables下新建一个entities文件夹 -> 在文件夹中新建我们的生物掉落物.json文件(文件名称与EntityInit.java中保持一致)

{"type": "minecraft:entity","pools": [{"rolls": 1.0,       "bonus_rolls": 0.0,"entries": [{"type": "item","name": "re8joymod:blackfeather", //掉落物格式: 模组名称:物品名称"weight": 6,"functions": [{"function": "set_count",    //掉落个数"count": {"min": 0,   //最少掉几个"max": 2    //最多掉几个}},{"function": "looting_enchant","count": {"min": 0,"max": 1}}]},{"type": "item","weight": 5,"name": "minecraft:totem_of_undying",   //原版掉落物格式: minecraft:物品名称"functions": [{"function": "set_count","count": {"min": 2,"max": 3}}]},{"type": "item","weight": 5,"name": "minecraft:nether_star","functions": [{"function": "set_count","count": {"min": 3,"max": 5}}]}]},{"name": "pool1","rolls": 1,"entries": [{"type": "item","name": "minecraft:bone","weight": 10},{"type": "item","name": "minecraft:ghast_tear","weight": 4},{"type": "item","weight": 5,"name": "minecraft:nether_star","functions": [{"function": "set_count","count": {"min": 3,"max": 5}}]}]}]
}

6.生物蛋制作

在ItemInit中添加:

        //刷怪蛋格式:ForgeSpawnEggItem(生物类,颜色1,颜色2,放在哪个物品栏)
public static final RegistryObject<Item> THIEF_EGG = ITEMS.register("re8dimi_spawn_egg", () -> new ForgeSpawnEggItem(EntityInit.RE8DIMI, 9577503, 13423070, new Item.Properties().tab(Main.TUTORIAL_TAB)));

在resources\assets\re8joymod\models\item中新建一个刷怪蛋.json文件(名称与ItemInit中的名称保持一致)

re8dimi_spawn_egg.json

{"parent": "item/template_spawn_egg"
}

在en_us.lang中添加语言信息:

"item.re8joymod.re8dimi_spawn_egg": "Alcina Dimitrescu Spawn Egg",

7.保存所有文件，刷新项目 -> 启动游戏

我们的Boss成功生成！
