Minecraft 1.19.2 Forge模组开发 10.3D动画盔甲

我们本次在1.19.2的版本中实现具有动画效果的3D盔甲

$效果演示$

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:1.19.2-43.1.1'

    //添加这个
    modImplementation 'software.bernie.geckolib:geckolib-fabric-1.19:3.1.18'

}

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3D盔甲：

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:

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，接下来需要制作我们的盔甲类

在items包中新建armor包 -> armor包中新建我们的套装类`ChandlierArmorItem`

ChandlierArmorItem.java

package net.joy187.joyggd.item.armor;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

import net.joy187.joyggd.Main;
import net.joy187.joyggd.init.ItemInit;

import net.minecraft.world.entity.EquipmentSlot;
import net.minecraft.world.entity.LivingEntity;
import net.minecraft.world.entity.decoration.ArmorStand;
import net.minecraft.world.entity.player.Player;
import net.minecraft.world.item.ArmorItem;
import net.minecraft.world.item.ArmorMaterial;
import net.minecraft.world.item.Item;
import net.minecraft.world.item.ItemStack;
import net.minecraft.world.item.Item.Properties;
import net.minecraft.world.level.Level;
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;
import software.bernie.geckolib3.item.GeoArmorItem;


public class ChandlierArmorItem extends GeoArmorItem implements IAnimatable{
	private AnimationFactory factory = new AnimationFactory(this);

	public ChandlierArmorItem(ArmorMaterial materialIn, EquipmentSlot slot, Properties builder) {
		super(materialIn, slot, builder.tab(Main.ITEM_TAB));
	}
	
    //动画状态机，判断每个时刻我们的盔甲的动画状态
	@SuppressWarnings("unused")
	private <P extends IAnimatable> PlayState predicate(AnimationEvent<P> event) {
		List<EquipmentSlot> slotData = event.getExtraDataOfType(EquipmentSlot.class);
		List<ItemStack> stackData = event.getExtraDataOfType(ItemStack.class);
		LivingEntity livingEntity = event.getExtraDataOfType(LivingEntity.class).get(0);

		if(!event.isMoving())
		{
			event.getController().setAnimation(new AnimationBuilder().addAnimation("animation.chandlier.rotate", true));
		}

		// If the living entity is an armorstand just play the animation nonstop
		if (livingEntity instanceof ArmorStand) {
			return PlayState.CONTINUE;
		}


		else if (livingEntity instanceof Player) {
			Player player = (Player) livingEntity;

			// Get all the equipment, aka the armor, currently held item, and offhand item
			List<Item> equipmentList = new ArrayList<>();
			player.getAllSlots().forEach((x) -> equipmentList.add(x.getItem()));
			
            //我们本次只制作一个头盔，所以subList为(5,6)
			// elements 2 to 6 are the armor so we take the sublist. Armorlist now only
			// contains the 4 armor slots
			List<Item> armorList = equipmentList.subList(5, 6);

			boolean isWearingAll = armorList
					.containsAll(Arrays.asList(ItemInit.CHANDLIER.get()));
			return isWearingAll ? PlayState.CONTINUE : PlayState.STOP;
		}
		return PlayState.STOP;
	}
	
	//将我们的待机动画进行注册
	@SuppressWarnings({ "unchecked", "rawtypes" })
	@Override
	public void registerControllers(AnimationData data) {
		data.addAnimationController(new AnimationController(this, "controller", 20, this::predicate));
	}

	@Override
	public AnimationFactory getFactory() {
		return this.factory;
	}
	
	//穿上盔甲后是否给予我们特殊效果
//    @Override
//    public void onArmorTick(ItemStack stack, Level world, Player player) {
//        if(!world.isClientSide()) {
//            if(!player.getInventory().getArmor(3).isEmpty()) {
//                MobEffectInstance mapStatusEffect1 = new MobEffectInstance(MobEffects.MOVEMENT_SPEED, 20*60, 1);
//                MobEffectInstance mapStatusEffect2 = new MobEffectInstance(MobEffects.NIGHT_VISION, 20*60, 1);
//
//                ArmorItem helmet = ((ArmorItem)player.getInventory().getArmor(3).getItem());
//                if(helmet.getMaterial() == CustomArmorMaterial.ARMOR_MATERIAL_ADASUIT) {
//                    boolean hasPlayerEffect = player.hasEffect(mapStatusEffect1.getEffect());
//                    if(!hasPlayerEffect) {
//                        player.addEffect(new MobEffectInstance(mapStatusEffect1.getEffect(),mapStatusEffect1.getDuration(), mapStatusEffect1.getAmplifier()));
//                        player.addEffect(new MobEffectInstance(mapStatusEffect2.getEffect(),mapStatusEffect2.getDuration(), mapStatusEffect2.getAmplifier()));
//                    }
//                }
//            	//player.addEffect(new MobEffectInstance(EffectInit.ZENHEART.get(), 100, 1));
//            }
//        }
//    }
    
}

之后我们需要在armor包中新建model包->model包中新建我们的盔甲的模型类`ModelChandlier`：

ModelChandlier.java

package net.joy187.joyggd.item.armor.model;


import net.joy187.joyggd.Main;
import net.joy187.joyggd.item.armor.ChandlierArmorItem;
import net.minecraft.resources.ResourceLocation;
import software.bernie.geckolib3.model.AnimatedGeoModel;


public class ModelChandlier extends AnimatedGeoModel<ChandlierArmorItem> {
	//盔甲模型文件地址
	@Override
	public ResourceLocation getModelResource(ChandlierArmorItem object) {
		return new ResourceLocation(Main.MOD_ID, "geo/chandlier.geo.json");
	}
	
    //盔甲材质文件地址
	@Override
	public ResourceLocation getTextureResource(ChandlierArmorItem object) {
		return new ResourceLocation(Main.MOD_ID, "textures/models/armor/chandlier_layer_1.png");
	}
	
    //盔甲动画文件地址
	@Override
	public ResourceLocation getAnimationResource(ChandlierArmorItem animatable) {
		return new ResourceLocation(Main.MOD_ID, "animations/chandlier.animation.json");
	}
}

之后我们需要在armor包中新建render包->render包中新建我们的盔甲的渲染类`RenderChandlier`：

RenderChandlier.java

package net.joy187.joyggd.item.armor.render;


import net.joy187.joyggd.item.armor.ChandlierArmorItem;
import net.joy187.joyggd.item.armor.model.ModelChandlier;
import software.bernie.geckolib3.renderers.geo.GeoArmorRenderer;


public class RenderChandlier extends GeoArmorRenderer<ChandlierArmorItem> {
	//渲染盔甲穿在身上的每一个部位的效果
	public RenderChandlier() {
		super(new ModelChandlier());
        //这里要和第二步你blockbench中建模的名称一一对应
		this.headBone = "Head";
		this.bodyBone = "chestplate";
		this.rightArmBone = "rightArm";
		this.leftArmBone = "leftArm";
		this.rightLegBone = "rightLeg";
		this.leftLegBone = "leftLeg";
		this.rightBootBone = "rightBoot";
		this.leftBootBone = "leftBoot";
	}
	
}

4.在`ClientModEventSubscriber`类中将我们的盔甲渲染类进行注册：

ClientModEventSubscriber.java

@Mod.EventBusSubscriber(modid = Main.MOD_ID, value = Dist.CLIENT, bus = Mod.EventBusSubscriber.Bus.MOD)
public class ClientModEventSubscriber extends ModEventSubscriber{
	
    @SubscribeEvent
    public static void registerRenderers(final EntityRenderersEvent.AddLayers event) {
        //渲染类进行注册
        GeoArmorRenderer.registerArmorRenderer(ChandlierArmorItem.class, RenderChandlier::new);
    }
}

5.在ItemInit类中将我们的盔甲进行声明，盔甲属性请参考1.18的教程，一模一样：1.18.2 盔甲套装：

ItemInit.java

    //头盔
    public static final RegistryObject<ChandlierArmorItem> CHANDLIER = ITEMS.register("chandlier",
            () -> new ChandlierArmorItem(CustomArmorMaterial.ARMOR_MATERIAL_CHANDLIER, EquipmentSlot.HEAD, new Item.Properties()));

6.代码部分结束，之后来到材质包制作环节：

在resources\assets\你的modid中的lang包中的en_us.json添加盔甲的英文名称：

"item.joyggd.chandlier":"Chandlier",

在`models\item`包中添加所有盔甲的模型文件：

chandlier.json

{
  "parent":"minecraft:item/generated",
  "textures":{
    "layer0":"joyggd:item/chandlier"
  }
}

在`textures\item`中添加盔甲的手持贴图：

在`textures\models\armor`中添加盔甲的穿戴后贴图：

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
