我们本次实现一个具有动画效果的物品，本次演示的模型代码均在文末给出

效果演示效果演示效果演示

首先，请确保你的开发包中引入了geckolib依赖，相关教程请参考:Minecraft 1.19.2 Forge模组开发 03.动画生物实体

1.首先我们要使用geckolib制作一个物品和对应的动画：

在blockbench中新建一个

之后我们找到Geckolib Model Settings并点击将模型转换为Block/Item：

之后导出物品模型文件，动画文件，展示文件：

将这些文件分别放入到resources包中的如下位置：

2.在items包中新建一个我们的物品类ItemTribody：

ItemTribody.java

package com.joy187.re8joymod.items;import com.joy187.re8joymod.Main;
import com.joy187.re8joymod.items.render.RenderTribody;
import net.minecraft.client.renderer.BlockEntityWithoutLevelRenderer;
import net.minecraft.world.item.Item;
import net.minecraftforge.client.extensions.common.IClientItemExtensions;
import software.bernie.example.GeckoLibMod;
import software.bernie.example.client.renderer.item.PistolRender;
import software.bernie.geckolib3.core.AnimationState;
import software.bernie.geckolib3.core.IAnimatable;
import software.bernie.geckolib3.core.PlayState;
import software.bernie.geckolib3.core.builder.AnimationBuilder;
import software.bernie.geckolib3.core.builder.ILoopType;
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;
import software.bernie.geckolib3.network.GeckoLibNetwork;
import software.bernie.geckolib3.network.ISyncable;
import software.bernie.geckolib3.util.GeckoLibUtil;import java.util.function.Consumer;public class ItemTribody extends Item implements IAnimatable {public AnimationFactory factory = new AnimationFactory(this);public ItemTribody() {super(new Item.Properties().tab(Main.TUTORIAL_TAB).stacksTo(1));}@Overridepublic void initializeClient(Consumer consumer) {super.initializeClient(consumer);consumer.accept(new IClientItemExtensions() {//物品渲染类private final BlockEntityWithoutLevelRenderer renderer = new RenderTribody();@Overridepublic BlockEntityWithoutLevelRenderer getCustomRenderer() {return renderer;}});}//动画控制器@Overridepublic void registerControllers(AnimationData data) {data.addAnimationController(new AnimationController(this, "controller",0, this::predicate));}//动画播放设定private  PlayState predicate(AnimationEvent event) {//这里我们默认循环播放名为"animation.tribody.run"的动画event.getController().setAnimation(new AnimationBuilder().addAnimation("animation.tribody.run", true));return PlayState.CONTINUE;}@Overridepublic AnimationFactory getFactory() {return this.factory;}
}

在ItemInit类中将我们的物品进行注册：

ItemInit.java

    public static RegistryObject DROP = register("tribody",()->{return new ItemTribody();});

3.在Item包中新建一个model包，model包中新建一个物品模型类ModelTribody，用于指定我们的物品模型：

ModelTribody.java

package com.joy187.re8joymod.items.model;import com.joy187.re8joymod.Main;
import com.joy187.re8joymod.items.ItemTribody;
import net.minecraft.resources.ResourceLocation;
import software.bernie.geckolib3.model.AnimatedGeoModel;public class ModelTribody extends AnimatedGeoModel{//模型文件在资源包中的路径@Overridepublic ResourceLocation getModelResource(ItemTribody object) {return new ResourceLocation(Main.MOD_ID, "geo/tribody.geo.json");}//贴图文件在资源包中的路径@Overridepublic ResourceLocation getTextureResource(ItemTribody object) {return new ResourceLocation(Main.MOD_ID, "textures/item/drop2.png");}//动画文件在资源包中的路径@Overridepublic ResourceLocation getAnimationResource(ItemTribody animatable) {return new ResourceLocation(Main.MOD_ID, "animations/tribody.animation.json");}
}

4.在Item包中新建一个render包，包中新建类RenderTribody，用于指定我们的物品渲染：

RenderTribody.java

package com.joy187.re8joymod.items.render;import com.joy187.re8joymod.items.ItemTribody;
import com.joy187.re8joymod.items.model.ModelTribody;
import software.bernie.geckolib3.renderers.geo.GeoItemRenderer;public class RenderTribody extends GeoItemRenderer {public RenderTribody() {//里面传入上一步中的物品模型类super(new ModelTribody());}
}

5.代码部分完成，由于第一步中我们已经将各种文件放好了，所以只需要在资源包的lang文件夹中添加物品的英文、中文名称：

en_us.json

"item.re8joymod.tribody": "Drop",

中文名称

zh_cn.json

"item.re8joymod.tribody": "水滴",

6.保存所有代码文件，运行游戏：

当我们把物品拿在手上：

本次演示物品的动画模型文件(参照第一步放入geo包)：
