# 让水鸭活动起来
|

在材质包完成了水鸭的一切工作后，开发者回到行为包上。在这里，我们可以使用原版的鸡行为去掉一部分多余的内容，增加一些新的行为，来模拟出水鸭的行为状态。

```
|
||
|
||
|
||
|
||
1）将format_version格式设置为最新的1.16.0，水鸭作为一个带有生物蛋的生物，我们将is_summonable（可用指令生成的）设置为true（真），is_spawnable（可用生物蛋）设置为true（真），is_experimental（是否是实验玩法打开才能看到的生物）设置为false（否）。同时将runtime_identifier指向自己。
|
||
|
||
2）行为组内的组合都清空，同时在原本鸡的行为上，加入”minecraft:behavior.rise_to_liquid_level“行为，这是一个来自炽足兽的新行为。可以让生物在水面上下起伏，就像水上的鸭子一样。
|
||
|
||
3）其中行为内部属性里，priority设置为0，即最高级优先使用的行为。liquid_y_offset设置为-0.5。rise_delta是上升增量，sink_delta是下降增量，来模拟鸭子的上下起伏。这里都设置为0.01。这样一个可爱的绿头鸭就做好了。
