# 树/树生成器

## 创建树叶和木块

为了创建自定义树木，你需要为每棵树创建两个方块：树叶和木块。

### 按照本教程创建方块

{% content-ref url="/pages/cv3Rv9Yu5e3P6qrnwvZu" %}
[方块](/chinese/cha-jian-shi-yong-fang-fa/adding-content/block.md)
{% endcontent-ref %}

例如，我按照教程创建了两个方块：`my_leaves`，`my_log`。

```yaml
info:
  namespace: myitems
items:
  my_leaves:
    display_name: "My Leaves"
    permission: myitems.my_leaves
    resource:
      material: PAPER
      generate: true
      textures:
      - block/my_leaves.png
    specific_properties:
      block:
        hardness: 0.2
        cancel_drop: true
        placed_model:
          type: REAL_TRANSPARENT
          break_particles: ITEM
  my_log:
    display_name: "My Log"
    permission: myitems.my_log
    resource:
      material: PAPER
      generate: true
      textures:
      - block/my_log/log_top.png
      - block/my_log/log.png
      - block/my_log/log.png
      - block/my_log/log.png
      - block/my_log/log_top.png
      - block/my_log/log.png
    specific_properties:
      block:
        hardness: 1.7
        placed_model:
          type: REAL
          break_particles: ITEM
        break_tools_whitelist:
        - _AXE
        - _axe
        - HAND
```

## 创建树苗（可选）

### 树苗物品

```yaml
items:
  orange_tree_sapling:
    display_name: Sapling
    permission: orange_tree_sapling
    resource:
      material: ORANGE_WOOL
      generate: true
      textures:
      - block/orange/sapling.png
    behaviours:
      sapling:
        tree_populator: orange_tree
```

### 自定义树木生成器

```yaml
trees_populators:
  orange_tree:
    worlds:
    - world
    chance: 5.0
    max_height: 100
    min_height: 50
    amount: 3
    iterations: 2
    log: newtrees:orange_tree_log
    leaves: newtrees:orange_tree_leaves
    tree_type: 
    biomes:
    - MOUNTAINS
```

## 在世界中生成树木

首先阅读本教程，了解如何创建树木方块（树叶和木块）

{% hint style="danger" %}
**末地维度**

建议**不要**在**末地**维度生成树木，因为它有一些**问题**。

**原版树木错误**

有时树木会生成带有原版树叶，这是一个已知问题，我没有解决方案。似乎是Minecraft/Spigot的错误，IA使用的某个事件有时不会触发。

**大树卡顿**

大树在生成时可能会导致一些卡顿，请仅使用小型树木类型。

**其他问题**
{% endhint %}

## 使树木随机生成

为了使树木在世界中生成，你需要创建一个`tree_populator`。

```yaml
info:
  namespace: myitems
trees_populators:
  my_tree:
    worlds:
    - world
    bottom_blocks:
    - DIRT
    - GRASS_BLOCK
    - PODZOL
    chance: 40.0
    max_height: 100
    min_height: 50
    amount: 3
    iterations: 2
    tree_type: TREE
    leaves: myitems:my_leaves
    log: myitems:my_log
    biomes:
    - PLAINS
    - SUNFLOWER_PLAINS
    - MOUNTAINS
```

### worlds

此属性指定树木可以生成的世界。

### bottom\_block

此属性指定树木可以生成在哪种方块上。

### chance

树木在一个区块中生成的几率。

### min\_height 和 max\_height

决定树木生成的高度区间。

### amount

每组生成的树木数量。

### iterations

如果**几率**匹配，当前区块中需要生成的树木组数。

### tree\_type

要生成的树木类型。完整列表可以在[这里](https://hub.spigotmc.org/javadocs/spigot/org/bukkit/TreeType.html)找到。\
此属性是可选的，如果不设置，此树木将在每个生物群系中生成。

### leaves

用于此树木的树叶方块。

### log

用于此树木的木块。

### biomes

树木可以生成的生物群系列表。完整列表可以在[这里](https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/Biome.html)找到。\
此属性是可选的，如果不设置，此树木将在每个生物群系中生成。
