# 地表补丁生成教程
|
||
|
||
<!--@include: @/wiki/bedrock-wiki-mirror.md-->
|
||
|
||
基于特征的地表构建器是一种将多种方块组合生成的功能，用于为主世界地表增添多样性和装饰效果。本教程将详细讲解如何创建这种地表特征，包括尺寸、生成频率、生成位置等参数设置！
|
||
|
||
## 单方块特征
|
||
|
||
单方块特征将作为我们地表构建的基础。它们定义了我们将要使用的具体方块类型。本教程将使用粗泥、灰化土和圆石作为示例。

||

## 权重随机特征
|
||
|
||
权重随机特征将作为我们的_随机选择器_，用于在不同方块类型之间进行概率选择。

## 散点特征
|
||
|
||
散点特征是我们地表构建的重要部分。它将决定单个斑块中方块的数量、形状和分布范围。
|
||
|
||
了解更多散点特征知识[请点击此处](/wiki/world-generation/feature-types#scatter-features)
|
||
|
||
::: code-group
|
||
```json [BP/features/scatter_surface_block_feature.json]
|
||
{
|
||
"format_version": "1.13.0",
|
||
"minecraft:scatter_feature": {
|
||
"description": {
|
||
"identifier": "wiki:scatter_surface_block_feature"
|
||
},
|
||
"iterations": "math.random_integer(20,25)",
|
||
"x": {
|
||
"extent": [0, 8],
|
||
"distribution": "gaussian"
|
||
},
|
||
"z": {
|
||
"extent": [0, 8],
|
||
"distribution": "gaussian"
|
||
},
|
||
"y": "q.heightmap(v.worldx, v.worldz) -1",
|
||
"places_feature": "wiki:select_surface_block_feature" // 权重随机特征的标识符
|
||
}
|
||
}
|
||
```
|
||
:::
|
||
|
||
- `iterations` 决定将放置的方块数量。使用Molang的 `math.random_integer` 函数可实现数量随机化。本示例中将在20到25个方块之间随机
|
||
|
||
- `extent` 使用数组决定斑块尺寸。`[0, 8]` 表示斑块从0到8格扩展。因此，我们的斑块在X和Z轴上将延伸8格。**该参数仅适用于X和Z轴分布**
|
||
|
||
- `"y": "q.heightmap(v.worldx, v.worldz) -1` 表示方块将放置于当前地表最高点的Y坐标-1处，即始终在地表生成
|
||
|
||
- `distribution` 指定分布类型。可用选项包括：`Gaussian`（高斯分布）、`Inverse Gaussian`（逆高斯分布）、`Uniform`（均匀分布）、`Fixed Grid`（固定网格）和`Jittered Grid`（抖动网格）
|
||
|
||
## 特征规则
|
||
|
||
这是地表构建的最后一步。地表构建器的特征规则设置略有不同。
