# AI
|
||
|
||
在本节中，我们回顾学习实体的AI控制。
|
||
|
||
## 在编辑器中添加
|
||
|
||
|
||
|
||
依旧以守卫实体为例，我们可以看到在行为包组件中添加了很多以“行为.”开头的组件。这些组件便是与AI行为有关的组件。
|
||
|
||
|
||
|
||
我们也可以自行添加更多的其他行为。这些行为组件英文都是以`behavior.`开头。
|
||
|
||
## 实际文件
|
||
|
||
我们来观察守卫实体的行为包定义文件：

这相当的复杂，但我们仔细观察，依旧可以在`components`下找到`minecraft:behavior.`开头的相关组件。这边是与编辑器中行为组件相对应的实际文件中的实体组件。特别地，这样的组件被称为AI意向（AI Goal）组件。
|
||
|
||
比如，最上方的`minecraft:behavior.delayed_attack`便代表实体具有延迟攻击意向。你可以在官方参考文档[国际版 - 实体AI意向列表](https://mc.163.com/dev/mcmanual/mc-dev/mcguide/20-%E7%8E%A9%E6%B3%95%E5%BC%80%E5%8F%91/100-%E5%8F%82%E8%80%83%E8%B5%84%E6%96%99/13-AIGoalList.html?catalog=1)中找到所有AI意向的列表。
|
||
|
||
每一个AI意向都可选地接受一个`priority`字段，代表该意向的优先级，优先级以值更小的为更优先。每一个AI意向也可选地接受一个`control_flags`数组，其中可以添加字符串`look`、`move`、`jump`，用于调整该意向使用的控制旗标。大部分意向的控制旗标是默认选择好的，但对于某一些意向来说，精准调整控制旗标有助于精准控制意向触发的时机，例如`minecraft:behavior.timer_flag_1`、`minecraft:behavior.timer_flag_2`、`minecraft:behavior.timer_flag_3`等计时器意向。
