我的世界Minecraft1.12.2模组开发（10）生物实体1.制作模型2.创建生物类3.注册生物4.渲染生物注册渲染 5.测试1.制作模型
使用Blockbench制作我们的模型（需要一点美术功底）
选择文件-导出-导出为java实体
（导出为src\main\java\fenge\fmltutor\client\model\ModelKLwy.java）
模型机密：
package fenge.fmltutor.client.model;// Made with Blockbench 4.2.3// Exported for Minecraft version 1.7 - 1.12// Paste this class into your mod and generate all required importsimport net.minecraft.client.model.ModelBase;import net.minecraft.client.model.ModelBox;import net.minecraft.client.model.ModelRenderer;import net.minecraft.entity.Entity;import net.minecraft.util.math.MathHelper;public class ModelKLwy extends ModelBase {private final ModelRenderer leftleg;private final ModelRenderer rightleg;private final ModelRenderer body;private final ModelRenderer left;private final ModelRenderer cube_r1;private final ModelRenderer right;private final ModelRenderer head;public ModelKLwy() {textureWidth = 128;textureHeight = 128;leftleg = new ModelRenderer(this);leftleg.setRotationPoint(-4.0F, 12.0F, 0.0F);leftleg.cubeList.add(new ModelBox(leftleg, 0, 45, 7.0F, -4.0F, -5.0F, 5, 16, 6, 0.0F, false));rightleg = new ModelRenderer(this);rightleg.setRotationPoint(6.0F, 11.0F, -1.0F);rightleg.cubeList.add(new ModelBox(rightleg, 0, 45, -12.0F, -3.0F, -3.0F, 5, 16, 6, 0.0F, false));body = new ModelRenderer(this);body.setRotationPoint(2.0F, -3.5F, 0.5F);setRotationAngle(body, 0.0F, -1.5272F, 0.0F);body.cubeList.add(new ModelBox(body, 21, 0, -5.0F, -11.5F, -7.5F, 6, 23, 15, 0.0F, false));left = new ModelRenderer(this);left.setRotationPoint(-7.0F, -12.5F, -2.0F);cube_r1 = new ModelRenderer(this);cube_r1.setRotationPoint(-1.0F, -1.0F, 0.0F);left.addChild(cube_r1);setRotationAngle(cube_r1, 0.0F, 0.0F, 0.0F);cube_r1.cubeList.add(new ModelBox(cube_r1, 24, 50, -3.0F, -1.5F, -2.0F, 6, 23, 6, 0.0F, false));right = new ModelRenderer(this);right.setRotationPoint(11.0F, -10.5F, -10.0F);setRotationAngle(right, -0.0958F, 0.0186F, -2.4861F);right.cubeList.add(new ModelBox(right, 0, 39, -3.4243F, -4.0334F, 5.0413F, 6, 23, 6, 0.0F, false));head = new ModelRenderer(this);head.setRotationPoint(2.5F, -19.1667F, 1.0F);setRotationAngle(head, 0.0F, 0.0F, 0.0F);head.cubeList.add(new ModelBox(head, 68, 4, -7.5F, -6.8333F, -6.0F, 13, 11, 10, 0.0F, false));head.cubeList.add(new ModelBox(head, 0, 0, 0.5F, -8.8333F, -4.0F, 4, 2, 6, 0.0F, false));head.cubeList.add(new ModelBox(head, 0, 0, -6.5F, -8.8333F, -4.0F, 4, 2, 6, 0.0F, false));}@Overridepublic void render(Entity entity, float f, float f1, float f2, float f3, float f4, float f5) {leftleg.render(f5);rightleg.render(f5);body.render(f5);left.render(f5);right.render(f5);head.render(f5);}public void setRotationAngle(ModelRenderer modelRenderer, float x, float y, float z) {modelRenderer.rotateAngleX = x;modelRenderer.rotateAngleY = y;modelRenderer.rotateAngleZ = z;}//动画效果（涉及大量小学生看不懂的公式，请在中学生的陪同下谨慎观看）@Overridepublic void setRotationAngles(float limbSwing, float limbSwingAmount, float ageInTicks, float netHeadYaw, float headPitch, float scaleFactor, Entity entityIn) {this.head.rotateAngleX=(float) (Math.PI/180)*headPitch;this.head.rotateAngleY=(float) (Math.PI/180)*netHeadYaw;this.leftleg.rotateAngleX= MathHelper.cos(limbSwing*0.6662F)*limbSwingAmount*1.25F;this.rightleg.rotateAngleX=MathHelper.cos(limbSwing*0.6662F+(float) Math.PI)*limbSwingAmount*1.25F;this.left.rotateAngleX= MathHelper.cos(limbSwing*-0.6662F)*limbSwingAmount*1.25F;}}
2.创建生物类
在src\main\java\fenge\fmltutor\entity创建EntityKLwy.java
package fenge.fmltutor.entity;import fenge.fmltutor.ExampleMod;import net.minecraft.entity.SharedMonsterAttributes;import net.minecraft.entity.ai.*;import net.minecraft.entity.monster.EntityMob;import net.minecraft.entity.player.EntityPlayer;import net.minecraft.init.Biomes;import net.minecraft.world.World;import net.minecraft.world.biome.Biome;//我们 开朗的网友 继承自EntityMob(绝大多数都是这样)public class EntityKLwy extends EntityMob {public static final String ID = "kl_wy";//生物id@Overrideprotected void initEntityAI() {//设置生物IDthis.tasks.addTask(0,new EntityAISwimming(this));//游泳AI this.tasks.addTask(1,new EntityAIAttackMelee(this,1.0,false));//攻击方式：近战this.tasks.addTask(2,new EntityAIWanderAvoidWater(this,0.8));//散步避免水this.tasks.addTask(4,new EntityAIWatchClosest(this, EntityPlayer.class,0.8F));//观察（跟随）附近的生物this.tasks.addTask(5,new EntityAILookIdle(this));//随处看（愣神）this.targetTasks.addTask(0,new EntityAIHurtByTarget(this,true));//仇恨攻击他的生物}@Override//设置生物属性protected void applyEntityAttributes(){super.applyEntityAttributes();this.getEntityAttribute(SharedMonsterAttributes.MAX_HEALTH).setBaseValue(20F);//最大血量（20）this.getEntityAttribute(SharedMonsterAttributes.ATTACK_DAMAGE).setBaseValue(5.0F);//攻击伤害this.getEntityAttribute(SharedMonsterAttributes.MOVEMENT_SPEED).setBaseValue(0.8F);//移动速度/格}public static final String NAME = ExampleMod.MODID+".KLWY";//名字（未本地化名称）public static final Biome[] BIOMES = {Biomes.PLAINS,Biomes.SAVANNA,Biomes.SAVANNA_PLATEAU,Biomes.MUTATED_PLAINS};//会在那些区块生成public EntityKLwy(World worldIn){super(worldIn);this.setSize(1.0F,1.8F);//设置碰撞箱大小}}
3.注册生物
在src\main\java\fenge\fmltutor\entity建立EntityRegistryHandler
package fenge.fmltutor.entity;import net.minecraft.entity.EnumCreatureType;import net.minecraftforge.event.RegistryEvent;import net.mon.Mod;import net.mon.eventhandler.SubscribeEvent;import net.mon.registry.EntityEntry;import net.mon.registry.EntityEntryBuilder;import net.minecraftforge.registries.IForgeRegistry;@Mod.EventBusSubscriberpublic class EntityRegistryHandler {/*EntityEntryBuilder.create().entity(EntityKLwy.class).id(EntityKLwy.ID,你的第几个生物).name(EntityKLwy.NAME).tracker(80,3,true（这个一般不改）).egg(0xffffff,0x000000（蛋的颜色）).spawn(EnumCreatureType.MONSTER,5,4,4,EntityKLwy.BIOMES（生物会出现的生物群系）).build();**/public static final EntityEntry KL_WY=EntityEntryBuilder.create().entity(EntityKLwy.class).id(EntityKLwy.ID,0).name(EntityKLwy.NAME).tracker(80,3,true).egg(0xffffff,0x000000).spawn(EnumCreatureType.MONSTER,5,4,4,EntityKLwy.BIOMES).build();@SubscribeEventpublic static void onRegistry(RegistryEvent.Register<EntityEntry> event){IForgeRegistry<EntityEntry> registry=event.getRegistry();registry.register(KL_WY);//注册你的生物}}
4.渲染生物
创建src\main\java\fenge\fmltutor\client\renderer\RenderKLwy.java
package fenge.fmltutor.client.renderer;import fenge.fmltutor.ExampleMod;import fenge.fmltutor.client.model.ModelKLwy;import fenge.fmltutor.entity.EntityKLwy;import net.minecraft.client.renderer.entity.RenderLiving;import net.minecraft.client.renderer.entity.RenderManager;import net.minecraft.entity.Entity;import net.minecraft.util.ResourceLocation;public class RenderKLwy extends RenderLiving {private static final ResourceLocation ENTITY_KL_WY_TEXTURE = new ResourceLocation(ExampleMod.MODID + ":textures/entity/" + EntityKLwy.ID + "/" + EntityKLwy.ID + ".png");//声明贴图位置public RenderKLwy(RenderManager manager){super(manager, new ModelKLwy(), 0.5F);//声明要渲染的模型（manager,new Model(),影子半径）}@Overrideprotected ResourceLocation getEntityTexture(Entity entity) {return ENTITY_KL_WY_TEXTURE;//输出贴图}}
把贴图保存为src\main\resources\assets\fmltutor\textures\entity\kl_wy\kl_wy.png
注册渲染
src\main\java\fenge\fmltutor\client\renderer\RenderRegistryHandler.java
package fenge.fmltutor.client.renderer;import fenge.fmltutor.entity.*;import net.minecraftforge.fml.client.registry.RenderingRegistry;public class RenderRegistryHandler {public static void register(){RenderingRegistry.registerEntityRenderingHandler(EntityKLwy.class,RenderKLwy::new);}}
然后在主类（有@MOD注解的类）中的preInitClient方法中注册
@EventHandler@SideOnly(Side.CLIENT)public void preInitClient(FMLPreInitializationEvent event){RenderRegistryHandler.register();}
5.测试
打开游戏：
嗯，开朗的网友出现在了游戏中！
