cr0.jpg

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

cr1.jpg

之后导出物品模型文件，动画文件，展示文件：

cr2.jpg

将这些文件分别放入到resources包中的如下位置：

cr3.jpg

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));
    }

    @Override
    public void initializeClient(Consumerconsumer) {super.initializeClient(consumer);
        consumer.accept(new IClientItemExtensions() {//物品渲染类
            private final BlockEntityWithoutLevelRenderer renderer = new RenderTribody();

            @Override
            public BlockEntityWithoutLevelRenderer getCustomRenderer() {return renderer;
            }
        });
    }
    
    //动画控制器
    @Override
    public void registerControllers(AnimationData data) {data.addAnimationController(new AnimationController(this, "controller",
                0, this::predicate));
    }

    //动画播放设定
    privatePlayState predicate(AnimationEventevent) {//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;
    }

    @Override
    public AnimationFactory getFactory() {return this.factory;
    }
}
在ItemInit类中将我们的物品进行注册：

ItemInit.java

public static RegistryObjectDROP = 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
    @Override
    public 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
    @Override
    public 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
    @Override
    public 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：

tri2.gif

本次演示物品的动画模型文件(参照第一步放入geo包)：
