我们本次尝试在1.19.2 Fabric中添加一个能够具有各种动画效果动作的生物实体。
效果展示 效果展示 效果展示
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modImplementation 'software.bernie.geckolib:geckolib-fabric-1.19:3.1.18'}
之后点击Refresh Gradle Project按钮重新构建项目
构建好了项目后在项目的ModMain类中添加一句geckolib的初始化语句：
ModMain.java
@Overridepublic void onInitialize() {ItemInit.registerModItems();//添加这个GeckoLib.initialize();}
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。
EntityGoose.json
package net.joy187.joyggd.entity;import net.minecraft.entity.EntityType;import net.minecraft.entity.ai.goal.LookAroundGoal;import net.minecraft.entity.ai.goal.SwimGoal;import net.minecraft.entity.ai.goal.WanderAroundFarGoal;import net.minecraft.entity.attribute.DefaultAttributeContainer;import net.minecraft.entity.attribute.EntityAttributes;import net.minecraft.entity.mob.MobEntity;import net.minecraft.entity.passive.ChickenEntity;import net.minecraft.world.World;import software.bernie.geckolib3.core.IAnimatable;import software.bernie.geckolib3.core.PlayState;import software.bernie.geckolib3.core.builder.AnimationBuilder;import software.bernie.geckolib3.core.controller.AnimationController;import software.bernie.geckolib3.core.event.predicate.AnimationEvent;import software.bernie.geckolib3.core.manager.AnimationData;import software.bernie.geckolib3.core.manager.AnimationFactory;public class EntityGoose extends ChickenEntity implements IAnimatable {private AnimationFactory factory = new AnimationFactory(this);public EntityGoose(EntityType<? extends ChickenEntity> entityType, World world) {super(entityType, world);// TODO Auto-generated constructor stub}//生物ai@Overrideprotected void initGoals() {this.goalSelector.add(1, new SwimGoal(this));this.goalSelector.add(3, new WanderAroundFarGoal(this, 0.75f, 1));this.goalSelector.add(4, new LookAroundGoal(this));}//生物一些属性public static DefaultAttributeContainer.Builder setAttributes() {return MobEntity.createMobAttributes().add(EntityAttributes.GENERIC_MAX_HEALTH, 10.0D).add(EntityAttributes.GENERIC_MOVEMENT_SPEED, 0.15f);}//生物动作状态机private <E extends IAnimatable> PlayState predicate(AnimationEvent<E> event) {//在空中时播放摔落动画if(!this.onGround){event.getController().setAnimation(new AnimationBuilder().addAnimation("animation.goose.fall", true));return PlayState.CONTINUE;}//移动时播放走路动画if (event.isMoving()) {event.getController().setAnimation(new AnimationBuilder().addAnimation("animation.goose.walk", true));return PlayState.CONTINUE;}//平时播放发呆动画event.getController().setAnimation(new AnimationBuilder().addAnimation("animation.goose.idle", true));return PlayState.CONTINUE;}//将状态机进行注册@Overridepublic void registerControllers(AnimationData data) {data.addAnimationController(new AnimationController<EntityGoose>(this, "controller",0, this::predicate));}@Overridepublic AnimationFactory getFactory() {return factory;}}
4.新建生物实体模型文件ModelGoose类：
ModelGoose.java
package net.joy187.joyggd.entity.model;import net.joy187.joyggd.ModMain;import net.joy187.joyggd.entity.EntityGoose;import net.minecraft.util.Identifier;import software.bernie.geckolib3.model.AnimatedGeoModel;public class ModelGoose extends AnimatedGeoModel<EntityGoose> {//模型文件地址@Overridepublic Identifier getModelResource(EntityGoose object) {return new Identifier(ModMain.MOD_ID, "geo/goose.geo.json");}//皮肤贴图文件地址@Overridepublic Identifier getTextureResource(EntityGoose object) {return new Identifier(ModMain.MOD_ID, "textures/entity/goose.png");}//动画文件地址@Overridepublic Identifier getAnimationResource(EntityGoose animatable) {return new Identifier(ModMain.MOD_ID, "animations/goose.animation.json");}}
5.模型部分结束，开始着手渲染类的编写。新建RenderGoose类。
RenderGoose.java
package net.joy187.joyggd.entity.render;import net.joy187.joyggd.ModMain;import net.joy187.joyggd.entity.EntityGoose;import net.joy187.joyggd.entity.model.ModelGoose;import net.minecraft.client.render.RenderLayer;import net.minecraft.client.render.VertexConsumer;import net.minecraft.client.render.VertexConsumerProvider;import net.minecraft.client.render.entity.EntityRendererFactory;import net.minecraft.client.util.math.MatrixStack;import net.minecraft.util.Identifier;import software.bernie.geckolib3.renderers.geo.GeoEntityRenderer;public class RenderGoose extends GeoEntityRenderer<EntityGoose> {public RenderGoose(EntityRendererFactory.Context ctx) {super(ctx, new ModelGoose());this.shadowRadius = 0.4f;}//贴图文件地址@Overridepublic Identifier getTextureResource(EntityGoose instance) {return new Identifier(ModMain.MOD_ID, "textures/entity/goose.png");}@Overridepublic RenderLayer getRenderType(EntityGoose animatable, float partialTicks, MatrixStack stack,VertexConsumerProvider renderTypeBuffer, VertexConsumer vertexBuilder,int packedLightIn, Identifier textureLocation) {//让你的生物体型放大多少倍（x，y，z三个方向）stack.scale(1f, 1f, 1f);return super.getRenderType(animatable, partialTicks, stack, renderTypeBuffer, vertexBuilder, packedLightIn, textureLocation);}}
6.在EntityInit.java中注册我们生物信息:
EntityInit.java
package net.joy187.joyggd.init;import net.fabricmc.fabric.api.object.builder.v1.entity.FabricEntityTypeBuilder;import net.joy187.joyggd.ModMain;import net.joy187.joyggd.entity.EntityGoose;import net.minecraft.entity.EntityDimensions;import net.minecraft.entity.EntityType;import net.minecraft.entity.SpawnGroup;import net.minecraft.util.Identifier;import net.minecraft.util.registry.Registry;public class EntityInit {public static final EntityType<EntityGoose> GOOSE = Registry.register(Registry.ENTITY_TYPE, new Identifier(ModMain.MOD_ID, "goose"), //你的modid，生物名称FabricEntityTypeBuilder.create(SpawnGroup.CREATURE, EntityGoose::new) //我们的生物属于CREATURE型.dimensions(EntityDimensions.fixed(0.6F, 1.5F)).build()); //EntityDimensions用于设置碰撞箱大小}
在ModClient.java中添加我们的模型渲染注册语句：
ModClient.java
package net.joy187.joyggd;import net.fabricmc.api.ClientModInitializer;import net.fabricmc.fabric.api.client.rendering.v1.EntityRendererRegistry;import net.joy187.joyggd.entity.render.RenderGoose;import net.joy187.joyggd.init.EntityInit;public class ModClient implements ClientModInitializer{@Overridepublic void onInitializeClient() {//添加渲染注册语句 第一个是我们的生物，第二个是渲染文件EntityRendererRegistry.register(EntityInit.GOOSE, RenderGoose::new);}}
在项目主类ModMain中添加生物属性注册语句：
ModMain.java
package net.joy187.joyggd;public class ModMain implements ModInitializer {public static final String MOD_ID = "joyggd";public static final Logger LOGGER = LoggerFactory.getLogger(MOD_ID);public static final ItemGroup ITEMTAB = FabricItemGroupBuilder.build(new Identifier(MOD_ID, "itemtab"), () -> new ItemStack(ItemInit.SHERIFF));@Overridepublic void onInitialize() {ItemInit.registerModItems();GeckoLib.initialize();//添加生物属性注册语句FabricDefaultAttributeRegistry.register(EntityInit.GOOSE, EntityGoose.setAttributes());}}
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：
//SpawnEggItem参数：生成的生物，刷怪蛋主颜色，刷怪蛋副颜色，放在哪个物品栏中public static final Item GOOSE_SPAWN_EGG = registerItem("goose_spawn_egg",new SpawnEggItem(EntityInit.GOOSE,0x22b341, 0x19732e,new FabricItemSettings().group(ModMain.ITEMTAB)));
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.joyggd.goose_spawn_egg": "Mob Spawn Egg","entity.joyggd.goose": "Mob",
在models\item包中添加刷怪蛋模型文件：
goose_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goose.json：
战利品文件中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。
goose.json
{"pools": [{"rolls": 1.0,"bonus_rolls": 0.0,"entries": [{"type": "item","name": "joyggd: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": "joyggd:blacksheephead","functions": [{"function": "set_count","count": {"min": 0,"max": 2}}]}]}]}
