效 果 展 示 效果展示 效果展示
我们本次尝试在1.19.2中添加一个能够具有各种动画效果动作的生物实体。
1.首先，为了实现这些动画效果，我们需要首先使用到一个模组:geckolib(下载地址)
找到项目的build.gradle文件，在repositories和dependencies中添加依赖。
repositories {//添加这个maven { url 'https://dl.cloudsmith.io/public/geckolib3/geckolib/maven/' }}dependencies {minecraft 'net.minecraftforge:forge:1.19.2-43.1.1'//添加这个implementation fg.deobf('software.bernie.geckolib:geckolib-forge-1.19:3.1.36')}
之后点击Load Gradle按钮重新构建项目
构建好了项目后在项目的Main类中添加一句geckolib的初始化语句：
Main.java
public Main(){IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus();// Register the commonSetup method for modloadingbus.addListener(this::commonSetup);bus.addListener(this::setup);ItemInit.ITEMS.register(bus);BlockInit.BLOCKS.register(bus);EntityInit.ENTITY_TYPES.register(bus);//添加这个GeckoLib.initialize();MinecraftForge.EVENT_BUS.register(this);}
2.之后，与之前的教程一样，我们需要在blockbench中制作一个模组中的生物实体：
进入软件后我们要找到一个插件按钮，然后再搜索栏中输入GeckoLib Animation Utils，并下载这个插件
将我们制作好的生物实体进行模型转换工作，找到Convert Project，之后选择Geckolib Animated Model
在这之后，你会发现你的生物实体栏多了一个Animate栏，点击进去:
具体动作制作的视频：Blockbench动画制作
在制作好所有的动画后我们导出模型和动画json文件。
3.模型制作完成，接下来需要制作生物实体类，因为我们的生物的动作有很多，所以要在生物的不同状态时做出对应的动作。

4.新建生物实体模型文件ModelDund类
ModelSamca.java
package com.joy187.re8joymod.entity.model;import com.joy187.re8joymod.Main;import com.joy187.re8joymod.entity.EntitySamca;import net.minecraft.client.model.geom.ModelLayerLocation;import net.minecraft.resources.ResourceLocation;import software.bernie.geckolib3.model.AnimatedGeoModel;public class ModelSamca extends AnimatedGeoModel<EntitySamca>{public static final ModelLayerLocation LAYER_LOCATION = new ModelLayerLocation(new ResourceLocation(Main.MOD_ID, "samca"), "main");@Overridepublic ResourceLocation getModelResource(EntitySamca object) {return new ResourceLocation(Main.MOD_ID, "geo/samca.geo.json");}@Overridepublic ResourceLocation getTextureResource(EntitySamca object) {return new ResourceLocation(Main.MOD_ID, "textures/entity/dund2.png");}@Overridepublic ResourceLocation getAnimationResource(EntitySamca animatable) {return new ResourceLocation(Main.MOD_ID, "animations/samca.animation.json");}}
5.模型部分结束，开始着手渲染类的编写。新建RenderDund类。
RenderDund.java
package com.joy187.re8joymod.entity.render;import com.joy187.re8joymod.Main;import com.joy187.re8joymod.entity.EntitySamca;import com.joy187.re8joymod.entity.model.ModelSamca;import com.mojang.blaze3d.vertex.PoseStack;import com.mojang.blaze3d.vertex.VertexConsumer;import net.minecraft.client.renderer.MultiBufferSource;import net.minecraft.client.renderer.RenderType;import net.minecraft.client.renderer.entity.EntityRendererProvider;import net.minecraft.resources.ResourceLocation;import software.bernie.geckolib3.renderers.geo.GeoEntityRenderer;public class RenderSamca extends GeoEntityRenderer<EntitySamca>{public RenderSamca(EntityRendererProvider.Context renderManager) {super(renderManager, new ModelSamca());this.shadowRadius = 0.5f;}@Overridepublic ResourceLocation getTextureLocation(EntitySamca instance) {//return LOCATION_BY_VARIANT.get(instance.getVariant());return new ResourceLocation(Main.MOD_ID, "textures/entity/dund2.png");}@Overridepublic RenderType getRenderType(EntitySamca animatable, float partialTicks, PoseStack stack,MultiBufferSource renderTypeBuffer, VertexConsumer vertexBuilder, int packedLightIn,ResourceLocation textureLocation) {// if(animatable.isBaby()) {// stack.scale(0.4F, 0.4F, 0.4F);// } else {// stack.scale(0.8F, 0.8F, 0.8F);// }stack.scale(1F, 1F, 1F);return super.getRenderType(animatable, partialTicks, stack, renderTypeBuffer, vertexBuilder, packedLightIn, textureLocation);}}
6.在EntityInit.java中添加我们的生物信息:
package com.joy187.re8joymod.init;import com.joy187.re8joymod.Main;import com.joy187.re8joymod.entity.EntitySamca;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.ENTITY_TYPES,Main.MOD_ID);public static final RegistryObject<EntityType<EntitySamca>> SAMCA = ENTITY_TYPES.register("samca",() -> EntityType.Builder.of(EntitySamca::new, MobCategory.MONSTER).sized(1f,1.8f).setTrackingRange(20).build(new ResourceLocation(Main.MOD_ID, "samca").toString()));}
在ClientModEventSubscriber.java中添加我们的模型渲染、属性注册语句：
@Mod.EventBusSubscriber(modid = Main.MOD_ID, value = Dist.CLIENT, bus = Mod.EventBusSubscriber.Bus.MOD)public class ClientModEventSubscriber{@SubscribeEventpublic static void onRegisterRenderer(EntityRenderersEvent.RegisterRenderers event) {//添加渲染注册语句event.registerEntityRenderer(EntityInit.SAMCA.get(), RenderSamca::new);//event.registerEntityRenderer(EntityInit.DETONATOR_ENTITY.get(), RenderDetonatorEntity::new);}@SubscribeEventpublic static void onAttributeCreate(EntityAttributeCreationEvent event) {//添加属性注册语句event.put(EntityInit.SAMCA.get(), EntitySamca.prepareAttributes().build());}}
7.生物实体部分结束，接下来我们要给生物制作一个刷怪蛋：
在ItemInit类中添加我们的刷怪蛋物品：
public static final RegistryObject<Item> SAMCA_SPAWN_EGG = ITEMS.register("samca_spawn_egg",() -> new ForgeSpawnEggItem(EntityInit.SAMCA, 3093009, 4390912, new Item.Properties().tab(Main.TUTORIAL_TAB)));
8.代码部分结束，来到资源包制作环节
在resources\assets\你的modid中的lang包中的en_us.json添加刷怪蛋和生物实体英文名称：
"item.re8joymod.samca_spawn_egg": "Mob Spawn Egg","entity.re8joymod.samca": "Mob",
在models\item包中添加刷怪蛋模型文件：
samca_spawn_egg.json
{"parent": "item/template_spawn_egg"}
在textures\entity中添加生物实体的皮肤贴图
新建一个geo包和animation包，把第二步中的模型和动画文件分别放进去
9.最后我们还要给这个生物设定其掉落物
在resources\data\你的modid中新建loot_tables包->loot_tables包中新建entities包 ->entities包中新建我们的战利品文件samaca.json
战利品文件中参数含义：
name为物品名称，weight为掉落权重，越大掉这个物品的概率越高，count为掉落个数，min为最小掉几个,max为最大掉几个。
samaca.json
{"pools": [{"rolls": 1.0,"bonus_rolls": 0.0,"entries": [{"type": "item","name": "re8joymod:lei","weight": 5,"functions": [{"function": "set_count","count": {"min": 1,"max": 3}},{"function": "looting_enchant","count": {"min": 0,"max": 1}}]},{"type": "item","weight": 10,"name": "minecraft:iron_nugget","functions": [{"function": "set_count","count": {"min": 2,"max": 3}}]},{"type": "item","weight": 10,"name": "minecraft:rotten_flesh","functions": [{"function": "set_count","count": {"min": 0,"max": 2}}]},{"type": "item","weight": 5,"name": "re8joymod:blacksheephead","functions": [{"function": "set_count","count": {"min": 0,"max": 2}}]}]}]}
