1.18.2动画生物实体教程
今天我们尝试在1.16.5中添加一个能够做各种动作的生物实体,由于使用的是geckolib进行开发，所以代码方面和1.18.2没有太大差别。
1.首先，为了实现这些效果，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:1.16.5-36.2.34'//添加这个implementation fg.deobf('software.bernie.geckolib:geckolib-forge-1.16.5:3.0.56')}
之后我们重新构建gradle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();ItemInit.ITEMS.register(bus);//添加GeckoLib初始化函数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，我们的生物的动画事件类似于状态机，所以要对生物实体的状态进行枚举。

true));return PlayState.CONTINUE;}//不走路就不放闲置动画event.getController().setAnimation(new AnimationBuilder().addAnimation("animation.ada.idle", true));return PlayState.CONTINUE;}private <E extends

{event.getController().setAnimation(new AnimationBuilder().addAnimation("animation.ada.attack", true));//System.out.println("打！");return PlayState.CONTINUE;}//生物攻击状态为1就播放攻击2动画if (this.entityData.get(STATE) == 2 && !(this.dead || this.getHealth() < 0.01 || this.isDeadOrDying())) {event.getController().setAnimation(new AnimationBuilder().addAnimation("animation.ada.attack2",

"controller",0, this::predicate));data.addAnimationController(new AnimationController(this, "controller1",0, this::predicate1));}@Overridepublic AnimationFactory getFactory() {return this.factory;}}
4.新建生物实体模型文件ModelAdawang类
ModelAdawang.java
import com.joy187.re8joymod.Utils;import net.minecraft.util.ResourceLocation;import software.bernie.geckolib3.model.AnimatedGeoModel;public class ModelAdawang extends AnimatedGeoModel {//获取geo模型文件地址@Overridepublic ResourceLocation getModelLocation(Object object) {return new ResourceLocation(Utils.MOD_ID, "geo/ada.geo.json");}//获取贴图文件地址@Overridepublic ResourceLocation getTextureLocation(Object object) {return new ResourceLocation(Utils.MOD_ID, "textures/entity/ada.png");}//获取动画文件地址@Overridepublic ResourceLocation getAnimationFileLocation(Object animatable) {return new ResourceLocation(Utils.MOD_ID, "animations/ada.animation.json");}}
5.模型部分结束，开始着手渲染类的编写。新建RenderAda类。
RenderAda.java
import com.joy187.re8joymod.Utils;import com.mon.entity.EntityAda;import com.mon.entity.model.ModelAdawang;import com.mojang.blaze3d.matrix.MatrixStack;import com.mojang.blaze3d.vertex.IVertexBuilder;import net.minecraft.client.renderer.IRenderTypeBuffer;import net.minecraft.client.renderer.RenderType;import net.minecraft.client.renderer.entity.EntityRendererManager;import net.minecraft.client.renderer.entity.MobRenderer;import net.minecraft.util.ResourceLocation;import software.bernie.example.client.model.entity.BikeModel;import software.bernie.example.entity.BikeEntity;import software.bernie.geckolib3.renderers.geo.GeoEntityRenderer;public class RenderAda extends GeoEntityRenderer<EntityAda> {public RenderAda(EntityRendererManager renderManager) {super(renderManager, new ModelAdawang());this.shadowRadius = 0.7f;}@Overridepublic ResourceLocation getTextureLocation(EntityAda instance) {return new ResourceLocation(Utils.MOD_ID, "textures/entity/ada.png");}@Overridepublic RenderType getRenderType(EntityAda animatable, float partialTicks, MatrixStack stack,IRenderTypeBuffer renderTypeBuffer, IVertexBuilder vertexBuilder, int packedLightIn,ResourceLocation textureLocation) {//生物按多少比例渲染如果是2F,2F,2F就是按照原有模型的2倍大小进行渲染stack.scale(1F, 1F, 1F);return RenderType.entityTranslucent(getTextureLocation(animatable));}}
6.在EntityInit.java中添加我们的生物信息:
public static final RegistryObject<EntityType<EntityAda>> ADA = ENTITY_TYPES.register("ada",() -> EntityType.Builder.of(EntityAda::new, EntityClassification.MONSTER).sized(1.5f,1.8f).setTrackingRange(30).build(new ResourceLocation(Utils.MOD_ID, "ada").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 onFMLClientSetupEvent(final FMLClientSetupEvent event) {//添加渲染注册语句RenderingRegistry.registerEntityRenderingHandler(EntityInit.ADA.get(), RenderAda::new);//RenderingRegistry.registerEntityRenderingHandler(EntityInit.MIA.get(), RenderMia::new);}}
在项目主类的setup函数的中添加属性注册:
Main.java
private void setup(final FMLCommonSetupEvent event) {DeferredWorkQueue.runLater(() -> GlobalEntityTypeAttributes.put(EntityInit.ADA.get(), EntityAda.setAttributes().build()));//DeferredWorkQueue.runLater(() -> GlobalEntityTypeAttributes.put(EntityInit.MIA.get(), EntityMia.setAttributes().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<SpawnEggItem> ADA_SPAWN_EGG = ITEMS.register("ada_spawn_egg",() -> new CustomSpawnEggItem(EntityInit.ADA, 14496298 , 3000,new Item.Properties().tab(RegistryEvents.RE8GROUP)));
7.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.ada_spawn_egg": "Mob Spawn Egg","entity.re8joymod.ada": "Mob",
在models\item包中添加刷怪蛋模型文件：
ada_spawn_egg.json
{"parent": "item/template_spawn_egg"}
