-====== 生成结构 ======
+====== 添加结构特征 [1.16.3] ======
+现在，往世界中注册并放置一些结构。
-===== 特征 =====
+入药查看原版结构的实例，可以从简单的''IglooFeature''和''IglooGenerator''开始。然而，制作新结构的上升的标准是使用拼图结构，这样更易于使用并可以让你少打一些代码。[[zh_cn:tutorial:jigsaw|这里有关于拼图结构和制作方法的教程。]]
-本教程中使用的所有代码都可以在此处获得: [[https://github.com/Draylar/fabric-structure-example-repo|fabric-structure-example-repo]]
+对于大多数基本的结构，你需要地物（feature）和生成器（generator）。地物处理注册结构并在生成世界时加载的过程。生成器处理方块的放置，或者在结构文件中加载（如果选择这样做）。
-==== 介绍 ====
+注意本教程依赖标记为实验性的[[https://github.com/FabricMC/fabric/pull/1097|Fabric API中的生物群系修改API]]。如果API不起作用，考虑使用[[?rev=1599808070|mixin版本]]。
-我们将研究如何在您的世界中注册和放置结构。
+===== 创建地物 =====
+要创建基本的地物（feature），我们推荐创建扩展''StructureFeature<DefaultFeatureConfig>''的类。大多数原版结构，如沉船、雪屋、神殿都是以''StructureFeature<DefaultFeatureConfig>''为基础，
-要查看实际使用的1.14原版结构的示例，IglooGenerator和IglooFeature是一个良好的开端。
+你需要覆写''getStructureStartFactory''方法。对于''getStructureStartFactory''，大多数原版的结构在其地物类中创建扩展''StructureStart''的类。
-对于最基本的结构，您将需要一个功能部件和生成器。 该功能处理在生成世界时注册结构并将其加载的过程-回答诸如“我应该在这里生成吗？”和‘我叫什么名字？’之类的问题，生成器处理块的放置或加载 结构文件（如果您选择这样做）。
+<code java>
-==== 创建特征 ====
+public class MyFeature extends StructureFeature<DefaultFeatureConfig> {
+  public MyFeature(Codec<DefaultFeatureConfig> codec) {
+    super(codec);
+  }
-要创建基本功能，我们建议创建一个扩展AbstractTempleFeature <DefaultFeatureConfig>的类。 海难，雪屋和神殿等各种原版结构都使用AbstractTempleFeature作为基础。 您将必须重写以下方法：
+  @Override
+  public StructureFeature.StructureStartFactory<DefaultFeatureConfig> getStructureStartFactory() {
+    return Start::new;
+  }
-   * shouldStartAt：出于测试目的，返回true。
+  public static class Start extends StructureStart<DefaultFeatureConfig> {
-   * getName：您的结构的名称
+    public Start(StructureFeature<DefaultFeatureConfig> feature, int chunkX, int chunkZ, BlockBox box, int references,
-   * getRadius：结构的半径，用于放置
+        long seed) {
-   * getSeeedModifier
+      super(feature, chunkX, chunkZ, box, references, seed);
+    }
-您可以将DefaultFeatureConfig :: deserialize传递给构造函数进行测试。
+    // 世界尝试在新的结构中生成时调用，同时也是地物和结构之间的“空隙（gap）”。
+    public void init(DynamicRegistryManager registryManager, ChunkGenerator chunkGenerator, StructureManager manager, int chunkX,
-对于getStructureStartFactory，大多数原始结构会创建一个在其Feature类中扩展StructureStart的类：
+        int chunkZ, Biome biome, DefaultFeatureConfig config) {
+      int x = chunkX * 16;
-<code java [enable_line_numbers="true"]>
+      int z = chunkZ * 16;
-public static class MyStructureStart extends StructureStart {
+      int y = chunkGenerator.getHeight(x, z, Heightmap.Type.WORLD_SURFACE_WG);
-    public MyStructureStart (StructureFeature<?> structureFeature_1, int int_1, int int_2, Biome biome_1, MutableIntBoundingBox mutableIntBoundingBox_1, int int_3, long long_1) {
+      BlockPos pos = new BlockPos(x, y, z);
-        super(structureFeature_1, int_1, int_2, biome_1, mutableIntBoundingBox_1, int_3, long_1);
+      BlockRotation rotation = BlockRotation.random(this.random);
-    }
+      MyGenerator.addPieces(manager, pos, rotation, this.children);
-    @Override
+      this.setBoundingBoxFromChildren();
-    public void initialize(ChunkGenerator<?> chunkGenerator, StructureManager structureManager, int chunkX, int chunkZ, Biome biome) {
-        DefaultFeatureConfig defaultFeatureConfig = chunkGenerator.getStructureConfig(biome, MyMainclass.myFeature);
-        int x = chunkX * 16;
-        int z = chunkZ * 16;
-        BlockPos startingPos = new BlockPos(x, 0, z);
-        Rotation rotation = Rotation.values()[this.random.nextInt(Rotation.values().length)];
-        MyGenerator.addParts(structureManager, startingPos, rotation, this.children, this.random, defaultFeatureConfig);
-        this.setBoundingBoxFromChildren();
     }
+  }
 }
 </code>
-当世界尝试以新结构生成时，这称为“要素”和“生成器”之间的差距。 在您的主类中对该变量的引用尚不存在，但我们将在最后创建它。 您也可以将配置设置为等于新的DefaultFeatureConfig。 您可以在getStructureStartFactory中使用返回MyStructureStart :: new返回此函数。
-这是结构文件和直接从generate方法生成的部分方式。 有两种解决方法：
-   *如果需要，您可以简单地在Feature类中重写generate，并使用setBlockState将块直接放置在世界上。 这是一个有效的选项，在1.13之前很流行。
+===== 创建生成器 =====
-   *使用结构文件和生成器。 在这一点上，这些功能非常强大，因此强烈建议使用。
+你可能已经注意到，我们需要创建生成器。
-==== Creating a Generator ====
+This is where structure files and generating straight from a ''generate'' method part ways. 有两种方式实现这样做：
-As you have probably noticed, we need to create a generator. We'll name it MyGenerator, and it's referenced in the initialize method of your StructureStart class. It doesn't need to override anything, but does require the following:
+  * If you want, you can simply override ''generate'' in your piece class and use ''addBlock'' to place blocks directly in the world. This is a valid option and was popular pre-1.13.
+  * Use structure files. These are rather powerful at this point and are highly recommended.
-  * An Identifier that points to your structure file; use "igloo/top" if you need an example.
+本教程中，使用结构文件，不需要override任何内容，但确实需要：
-  * Some sort of setup method - addParts is a good name:
+  * 指向结构文件的标识符（identifier，例如''"igloo/top"''。
+  * 一些安装方法——例如''addPieces''就很不错。
 <code java>
-public static void addParts(StructureManager structureManager_1, BlockPos blockPos_1, Rotation rotation_1,
+public class MyGenerator {
-    List<StructurePiece> list_1, Random random_1, DefaultFeatureConfig featureConfig)
+  private static final Identifier IGLOO_TOP = new Identifier("igloo/top");
+  public static void addPieces(StructureManager manager, BlockPos pos, BlockRotation rotation, List<StructurePiece> pieces) {
+    pieces.add(new MyPiece(manager, pos, IGLOO_TOP, rotation));
+  }
 }
 </code>
-In your addParts method, you can choose which structure pieces are added to your generation process. You can add a piece like this:
+在''addPieces''方法中，你可以选择往你的生成过程中添加哪些结构。
+我们现在//在生成器类中//创建我们刚刚提到的结构，创建名为''MyPiece''的类，继承''SimpleStructurePiece''。
+Override required methods, and add a constructor that takes in a ''StructureManager'', ''BlockPos'', ''Identifier'' and ''Rotation''.
+**toNbt isn't required but is available if you need it**.
+We're also implementing ''initializeStructureData'', which is not an override.
+We also have 2 constructors: 1 for our own pieces, and one for registry.
+A basic template would be:
 <code java>
-list_1.add(new MyGenerator.Piece(structureManager_1, identifier, blockPos, rotation_1));
+public static class MyPiece extends SimpleStructurePiece {
-</code>
+  private final BlockRotation rotation;
+  private final Identifier template;
-where the identifier is the path we created recently.
-We're now going to create the Piece we just referenced; make a class called Piece that extends SimpleStructurePiece //within your generator class//.
+  public MyPiece(StructureManager structureManager, CompoundTag compoundTag) {
+    super(ExampleMod.MY_PIECE, compoundTag);
+    this.template = new Identifier(compoundTag.getString("Template"));
+    this.rotation = BlockRotation.valueOf(compoundTag.getString("Rot"));
+    this.initializeStructureData(structureManager);
+  }
-Override required methods, and add a constructor that takes in a StructureManager, Identifier, BlockPos, and Rotation. **toNbt isn't required but is available if you need it**. We're also implementing our own setStructureData with different arguments, so it's not an override. We also have 2 constructors: 1 for our own pieces, and one for registry. A basic template would be:
+  public MyPiece(StructureManager structureManager, BlockPos pos, Identifier template, BlockRotation rotation) {
+    super(ExampleMod.MY_PIECE, 0);
+    this.pos = pos;
+    this.rotation = rotation;
+    this.template = template;
-<code java [enable_line_numbers="true"]>

+  }
-    private Rotation rotation;
-    private Identifier template;
+  private void initializeStructureData(StructureManager structureManager) {
+    Structure structure = structureManager.getStructureOrBlank(this.template);
-    public Piece(StructureManager structureManager_1, Identifier identifier_1, BlockPos blockPos_1, Rotation rotation_1) {
+    StructurePlacementData placementData = (new StructurePlacementData())
-        super(MyModClass.myStructurePieceType, 0);
+      .setRotation(this.rotation)
+      .setMirror(BlockMirror.NONE)
-        this.pos = blockPos_1;
+      .addProcessor(BlockIgnoreStructureProcessor.IGNORE_STRUCTURE_BLOCKS);
-        this.rotation = rotation_1;
+    this.setStructureData(structure, this.pos, placementData);
-        this.template = identifier_1;
+  }
-        this.setStructureData(structureManager_1);
+  protected void toNbt(CompoundTag tag) {
-    }
+    super.toNbt(tag);
+    tag.putString("Template", this.template.toString());
-    public Piece(StructureManager structureManager_1, CompoundTag compoundTag_1) {
+    tag.putString("Rot", this.rotation.name());
-        super(MyModClass.myStructurePieceType, compoundTag_1);
+  }
-        this.identifier = new Identifier(compoundTag_1.getString("Template"));
-        this.rotation = Rotation.valueOf(compoundTag_1.getString("Rot"));
+  @Override
-        this.setStructureData(structureManager_1);
+  protected void handleMetadata(String metadata, BlockPos pos, ServerWorldAccess serverWorldAccess, Random random,

-        this.setStructureData(structure_1, this.pos, structurePlacementData_1);
-    }
-    @Override

-handleMetadata is where you look at data blocks within your structure and do tasks based on what you find. In vanilla structures, data blocks are placed above chests so they can be filled with loot in this method.
+''handleMetadata'' is where you look at data blocks within your structure and can do tasks based on what you find.
+This can be good for dynamic stuff such as placing certain mobs based on what mod is on and so on.
-We set the StructurePieceType to MyModClass.myStructurePiece type; this is the variable that holds your registered structure piece. We'll handle that after we finish the generate function, which sets the position of your structure and generates it:
+In vanilla structures, data blocks are placed above chests so they can be filled with loot in this method.
+HOWEVER, you do not need to use datablocks to place chests with loot. Instead, use this command to set a north facing chest with a loottable.
+Save this chest into your structure's nbt file and it will generate loot when opened for the first time. (Don't open the chest before saving to the nbt file!)

-In this case, we simply get the y position of the highest block in the middle of our chunk and generate the structure off that position.

-For testing, it's a good idea to register your feature to every biome and set the spawn rate to 100% so you can be sure it's spawning and working.
