我的世界Minecraft1.12.2模组开发（10）生物实体
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 imports
import 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));
}
@Override
public 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）
@Override
public 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
@Override
protected void initEntityAI() {
//设置生物ID
this.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.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.common.registry.EntityEntry;
import net.minecraftforge.fml.common.registry.EntityEntryBuilder;
import net.minecraftforge.registries.IForgeRegistry;
@Mod.EventBusSubscriber
public 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();
@SubscribeEvent
public 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）
}
@Override
protected 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！
