# 半砖、楼梯、三叉戟、鞘翅等

### 半砖和楼梯

{% hint style="warning" %}
你不能创建实心的自定义半砖和楼梯。\
问题在于 Minecraft 不允许自定义自定义方块的碰撞箱。
{% endhint %}

### 三叉戟

{% hint style="warning" %}
你不能为投掷的三叉戟创建自定义模型，因为这是一个Minecraft的bug，我无法修复：[MC-155286](https://bugs.mojang.com/browse/MC-155286)
{% endhint %}

### 鞘翅

{% hint style="success" %}
将在未来的 ItemsAdder 版本中添加，但需要1.21.2客户端。
