Minecraft 1.16.5模组开发(三十一) 自定义建筑生成(structure) (新)

如果你学习过我们之前在1.12.2的建筑生成教程,那么对本次的教程的理解可能会相对轻松。

往期回顾

Minecraft 1.12.2模组开发(十四) 建筑生成 (structure generation)
Minecraft 1.12.2模组开发(二十二) 多种建筑生成

我们本次将在1.16.5版本中实现建筑的自动生成。

1.首先我们需要生成一个建筑的.nbt文件

创建一个新世界

通过命令让我们获得一个建筑方块:

/give @s minecraft:structure_block

之后我们建造一个建筑

通过对建筑操作的坐标变换,将我们这个建筑完全包裹在区域内:

点击’Save’,建筑成功保存下来

保存的建筑会生成一个.nbt文件,我们需要将这个文件找到,路径为
开发包\run\saves\1_8version_test(你的存档名称)\generated\minecraft\structures

2.在data包中新建structures文件夹,将生成的.nbt文件放入其中。

3.在worldgen文件夹中新建template_pool(建筑模板库)文件夹 -> 新建一个与我们建筑名称对应的文件夹(以tank1为例) -> 在tank1中新建一个start_pool.json文件

在start_pool.json中编写:
{
  "name": "re8joymod:tank1/start_pool", //格式:模组名:建筑名称/start_pool的文件路径
  "fallback": "minecraft:empty",
  "elements": [
    {
      "weight": 1,
      "element": {
        "location": "re8joymod:tank1",  //格式:模组名:建筑名称
        "processors": "minecraft:empty",
        "projection": "rigid",
        "element_type": "minecraft:single_pool_element"
      }
    }
  ]
}

4.在common文件夹下新建 world文件夹 -> world文件夹中新建structure文件夹 -> structure文件夹中新建 structures文件夹 -> structures中新建一个建筑物类(以Tank1Structure.java为例)

            // **THE FOLLOWING TWO LINES ARE OPTIONAL**

            // Right here, you can do interesting stuff with the pieces in this.pieces such as offset the

            // holds just the piece's size and positions. Blocks will be placed later in JigsawManager.
            //
            // In this case, we do `piece.offset` to raise pieces up by 1 block so that the house is not right on
            // the surface of water or sunken into land a bit.
            //
            // Then we extend the bounding box down by 1 by doing `piece.getBoundingBox().minY` which will cause the
            // land formed around the structure to be lowered and not cover the doorstep. You can raise the bounding
            // box to force the structure to be buried as well. This bounding box stuff with land is only for structures
            // that you added to Structure.NOISE_AFFECTING_FEATURES field handles adding land around the base of structures.
            //
            // By lifting the house up by 1 and lowering the bounding box, the land at bottom of house will now be

5.在刚刚新建的 structure文件夹中新建 ModStructure.java

在ModStructure.java中编写:

如果你出现了诸如这样的问题:

Minecraft 1.16.5模组开发(三十一) 自定义建筑生成(structure) (新)_第7张图片
这说明你还没有配置accesstransformer.cfg文件(路径:**resources/META-INF/**accesstransformer.cfg)
在该路径下新建一个accesstransformer.cfg文件,将如下的代码copy进去:

public-f net.minecraft.world.gen.feature.structure.Structure field_236384_t_ #LAND_TRANSFORMING_STRUCTURES
public-f net.minecraft.world.gen.settings.DimensionStructuresSettings field_236191_b_ #DEFAULT_STRUCTURE_CONFIGS
public-f net.minecraft.world.gen.FlatGenerationSettings field_202247_j #STRUCTURES
public-f net.minecraft.world.gen.settings.DimensionStructuresSettings field_236193_d_ #structures
之后对我们的build.gradle进行修改:
在’mappings channel’下方另起一行添加如下语句:
 accessTransformer = file('src/main/resources/META-INF/accesstransformer.cfg') 

Minecraft 1.16.5模组开发(三十一) 自定义建筑生成(structure) (新)_第8张图片

Gradle修改之后需要进行一次重新加载(过程略慢,请耐心等待)

之后报错的字段应该就自然消除了。

6.接下来我们需要在world/gen文件夹中新建一个所有的建筑的配置文件:ModConfiguredStructures.java

在ModConfiguredStructures中编写
package com.joy187.re8joymod.common.world.gen;

import com.joy187.re8joymod.Utils;
import com.joy187.re8joymod.common.world.structure.ModStructures;
import net.minecraft.util.ResourceLocation;
import net.minecraft.util.registry.Registry;
import net.minecraft.util.registry.WorldGenRegistries;
import net.minecraft.world.gen.FlatGenerationSettings;
import net.minecraft.world.gen.feature.IFeatureConfig;
import net.minecraft.world.gen.feature.StructureFeature;

public class ModConfiguredStructures {
    /**
     * Static instance of our structure so we can reference it and add it to biomes easily.
     */
     //你可以添加多个
    public static StructureFeature CONFIGURED_TANK1_HOUSE = ModStructures.TANK1.get().configured(IFeatureConfig.NONE);

    /**
     * Registers the configured structure which is what gets added to the biomes.
     * Noticed we are not using a forge registry because there is none for configured structures.
     *
     * We can register configured structures at any time before a world is clicked on and made.
     * But the best time to register configured features by code is honestly to do it in FMLCommonSetupEvent.
     */
    public static void registerConfiguredStructures() {
        Registry> registry = WorldGenRegistries.CONFIGURED_STRUCTURE_FEATURE;
        
        //可以继续添加多个
        Registry.register(registry, new ResourceLocation(Utils.MOD_ID, "configured_tank1_house"), CONFIGURED_TANK1_HOUSE);
        
         /*
         * Requires AccessTransformer ( see resources/META-INF/accesstransformer.cfg )
         */
         //将上方的你的所有的建筑都加进来(put函数)
        FlatGenerationSettings.STRUCTURE_FEATURES.put(ModStructures.TANK1.get(), CONFIGURED_TANK1_HOUSE);
    }
}

7.在world/gen文件夹中新建一个ModStructureGeneration.java 用于编写建筑在世界生成的相关规则:

在ModStructureGeneration.java中编写:
package com.joy187.re8joymod.common.world.gen;

import com.joy187.re8joymod.common.init.BiomeInit;
import com.joy187.re8joymod.common.world.structure.ModStructures;
import net.minecraft.util.RegistryKey;
import net.minecraft.util.registry.Registry;
import net.minecraft.world.biome.Biome;
import net.minecraft.world.gen.feature.IFeatureConfig;
import net.minecraft.world.gen.feature.StructureFeature;
import net.minecraftforge.common.BiomeDictionary;
import net.minecraftforge.event.world.BiomeLoadingEvent;

import java.util.List;
import java.util.Set;
import java.util.function.Supplier;

public class ModStructureGeneration {
    public static void generateStructures(final BiomeLoadingEvent event) {
        RegistryKey key = RegistryKey.create(Registry.BIOME_REGISTRY, event.getName());
        Set types = BiomeDictionary.getTypes(key);

        //这里是MC中的地形,你可以让你的建筑生成在想要的地形中
        //例如生成在平原:types.contains(BiomeDictionary.Type.PLAINS)
        if(types.contains(BiomeInit.RE8_BIOME)) {
            //你可以添加多个自己想要生成的建筑
            event.getGeneration().getStructures().add(() -> ModConfiguredStructures.CONFIGURED_TANK1_HOUSE);
        }
        //else if... 可以添加多个想要生成的地形中的建筑
    }
}

8.在ModWorldEvents.java中(没有则在world文件夹中新建)添加一个函数addDimensionalSpacing():

package com.joy187.re8joymod.common.world;

import com.google.common.collect.ImmutableList;
import com.google.common.collect.ImmutableMap;
import com.joy187.re8joymod.Utils;

import org.apache.logging.log4j.LogManager;

import javax.swing.plaf.synth.SynthTreeUI;
import java.lang.reflect.Method;
import java.util.HashMap;
import java.util.Map;

@Mod.EventBusSubscriber(modid = Utils.MOD_ID)
public class ModWorldEvents {

      //StructureTutorialMain.java

    @SubscribeEvent
    public static void biomeLoadingEvent(final BiomeLoadingEvent event) {
        //加入建筑的生成事件的声明
        ModStructureGeneration.generateStructures(event);

//        ModOreGeneration.generateOres(event);
//        ModFlowerGeneration.generateFlowers(event);
//        ModTreeGeneration.generateTrees(event);
    }

    //加入空间生成的相关设置
    @SubscribeEvent
    public static void addDimensionalSpacing(final WorldEvent.Load event) {
        if(event.getWorld() instanceof ServerWorld) {
            ServerWorld serverWorld = (ServerWorld) event.getWorld();
            
            //建筑生成异常就会抛出相应错误
            try {
                Method GETCODEC_METHOD =
                        ObfuscationReflectionHelper.findMethod(ChunkGenerator.class, "func_230347_a_");
                ResourceLocation cgRL = Registry.CHUNK_GENERATOR.getKey(
                        (Codec)GETCODEC_METHOD.invoke(serverWorld.getChunkSource().generator));

                if (cgRL != null && cgRL.getNamespace().equals("terraforged")) {
                    return;
                }
            } catch (Exception e) {
                LogManager.getLogger().error("Was unable to check if " + serverWorld.getLevel()
                        + " is using Terraforged's ChunkGenerator.");
            }
            
            
            // 放止建筑在超平坦世界生成
            if (serverWorld.getChunkSource().generator instanceof FlatChunkGenerator &&
                    serverWorld.getLevel().equals(World.OVERWORLD)) {
                return;
            }

            // 将我们的建筑添加到建筑生成地图中
            Map, StructureSeparationSettings> tempMap =
                    new HashMap<>(serverWorld.getChunkSource().generator.getSettings().structureConfig());
            tempMap.putIfAbsent(ModStructures.TANK1.get(),
                    DimensionStructuresSettings.DEFAULTS.get(ModStructures.TANK1.get()));
            serverWorld.getChunkSource().generator.getSettings().structureConfig = tempMap;
        }
    }

}

9.在Main.java进行修改(添加建筑的相关注册与初始化语句):

在setup()中添加:
        event.enqueueWork(() -> {
            ModStructures.setupStructures();
            ModConfiguredStructures.registerConfiguredStructures();

        });

在Main()中添加:
        ModStructures.register(bus);
        SurfaceBuilderInit.SURFACE_BUILDERS.register(bus);

10.代码的部分结束了,之后进入游戏进行测试:

新建一个世界 -> 进入后输入查找我们的建筑的指令:
/locate re8joymod:tank1

之后我们会得到建筑的具体坐标

输入tp指令进行坐标传送:

tp @s 具体坐标
