注册矿物

我们都知道，在矿物被挖掘之后，会掉落经验，所以我们需要使用ExperienceDroppingBlock来创建方块对象，之后需要创建两种矿物，一种是普通的矿物，一种是深层矿物。

ExperienceDroppingBlock的构造函数需要两个参数，第一个是掉落的经验数量，这里也就是创建了一个随机为 10-17 的经验掉落，第二个参数是方块的设置，这里设置了方块的颜色，敲击音效，硬度抗性，必须使用工具，以及挖掘音效。

public static final Block END_HEART_ORE = new ExperienceDroppingBlock(UniformIntProvider.create(10, 17), AbstractBlock.Settings.create().mapColor(MapColor.STONE_GRAY).instrument(Instrument.BASEDRUM).requiresTool().strength(3.0f, 3.0f).sounds(BlockSoundGroup.NETHER_ORE));

深层矿物的设置和普通矿物差不多，只不过需要调用copy方法。

public static final Block DEEPSLATE_END_HEART_ORE = new ExperienceDroppingBlock(UniformIntProvider.create(10, 17), AbstractBlock.Settings.copy(END_HEART_ORE).mapColor(MapColor.DEEPSLATE_GRAY).instrument(Instrument.BASEDRUM).requiresTool().strength(4.5f, 3.0f).sounds(BlockSoundGroup.DEEPSLATE));

最后，我们需要注册这两个矿物。

Registry.register(Registries.BLOCK, new Identifier("awesome", "end_heart_ore"), END_HEART_ORE);
Registry.register(Registries.BLOCK, new Identifier("awesome", "deepslate_end_heart_ore"), DEEPSLATE_END_HEART_ORE);

注册矿物物品

使用之前学习的方法，我们可以很容易的注册矿物物品。

矿物纹理

使用之前学习的方法，我们可以很容易的注册矿物纹理。

多语言文件

{
    "item.awesome.end_heart_ore": "End Heart Ore",
    "item.awesome.deepslate_end_heart_ore": "Deepslate End Heart Ore",
    "block.awesome.end_heart_ore": "End Heart Ore",
    "block.awesome.deepslate_end_heart_ore": "Deepslate End Heart Ore"
}

掉落物

这里会比较复杂，需要考虑精准采集和时运的影响，但我们可以使用原版中已经存在的配置。

我们进入到原版游戏中的data/minecraft/loot_tables/blocks/diamond_ore.json和data/minecraft/loot_tables/blocks/deepslate_diamond_ore.json将钻石矿的掉落配置加以修改。

可挖掘方块

我们需要在data/minecraft/tags/blocks/mineable/pickaxe.json中添加我们的矿物。

{
  "replace": false,
  "values": [
    "awesome:end_heart_ore",
    "awesome:deepslate_end_heart_ore"
  ]
}

矿物配方

首先添加熔炉的配方，还是在recipes下创建，格式就是物品ID_from_smelting_矿物ID.json，高炉的配方就是物品ID_from_blasting_矿物ID.json。

熔炉

{
  "type": "minecraft:smelting",
  "category": "misc",
  "cookingtime": 200,
  "experience": 1.0,
  "group": "end_heart",
  "ingredient": {
    "item": "awesome:end_heart_ore"
  },
  "result": "awesome:end_heart"
}

{
  "type": "minecraft:smelting",
  "category": "misc",
  "cookingtime": 200,
  "experience": 1.0,
  "group": "end_heart",
  "ingredient": {
    "item": "awesome:deepslate_end_heart_ore"
  },
  "result": "awesome:end_heart"
}

高炉

{
  "type": "minecraft:blasting",
  "category": "misc",
  "cookingtime": 100,
  "experience": 1.0,
  "group": "end_heart",
  "ingredient": {
    "item": "awesome:end_heart_ore"
  },
  "result": "awesome:end_heart"
}

{
  "type": "minecraft:blasting",
  "category": "misc",
  "cookingtime": 100,
  "experience": 1.0,
  "group": "end_heart",
  "ingredient": {
    "item": "awesome:deepslate_end_heart_ore"
  },
  "result": "awesome:end_heart"
}

矿物生成

首先创建矿物的configured_feature，在data\awesome\worldgen\configured_feature中，创建配置end_heart_ore.json。

其中discard_chance_on_air_exposure就是矿物在空气中曝露的概率，size就是矿物的大小，targets就是矿物生成的目标方块，predicate_type的意思就是判断tag中的方块是否符合要求，不过要注意的是state中的Name必须首字母大写。

{
  "type": "minecraft:ore",
  "config": {
    "discard_chance_on_air_exposure": 0.0,
    "size": 12,
    "targets": [
      {
        "state": {
          "Name": "awesome:end_heart_ore"
        },
        "target": {
          "predicate_type": "minecraft:tag_match",
          "tag": "minecraft:stone_ore_replaceables"
        }
      },
      {
        "state": {
          "Name": "awesome:deepslate_end_heart_ore"
        },
        "target": {
          "predicate_type": "minecraft:tag_match",
          "tag": "minecraft:deepslate_ore_replaceables"
        }
      }
    ]
  }
}

然后创建placed_feature，在data\awesome\worldgen\placed_feature中，创建配置end_heart_ore.json。

在placement中有四个参数，第一个是minecraft:count，就是矿物的数量，第二个是minecraft:in_square，就是矿物的生成范围，第三个是minecraft:height_range，就是矿物的生成高度，第四个是minecraft:biome，表示会在群系中生成。

{
  "feature": "awesome:end_heart_ore",
  "placement": [
    {
      "type": "minecraft:count",
      "count": 20
    },
    {
      "type": "minecraft:in_square"
    },
    {
      "type": "minecraft:height_range",
      "height": {
        "type": "minecraft:trapezoid",
        "max_inclusive": {
          "absolute": 70
        },
        "min_inclusive": {
          "absolute": -24
        }
      }
    },
    {
      "type": "minecraft:biome"
    }
  ]
}

最后注册PlacedFeature。

public static final RegistryKey<PlacedFeature> END_HEART_ORE_PLACED_FEATURE = RegistryKey.of(RegistryKeys.PLACED_FEATURE, new Identifier("awesome","end_heart_ore"));

并且在BiomeModifications中注册END_HEART_ORE_PLACED_FEATURE。

BiomeModifications.addFeature(BiomeSelectors.foundInOverworld(), GenerationStep.Feature.UNDERGROUND_ORES, END_HEART_ORE_PLACED_FEATURE);
