# 主角色和关注对象

1. 导航到你的 AI 角色蓝图。
2. 将 `Convai 聊天机器人` 将组件添加到事件图中。
3. 获取 `环境` 对象，并确保它有效。
   1. 使用函数 `设置主角色` 来将当前说话者定义为 AI 角色。此外，如果你使用的是 Convai 的动画蓝图，那么设置主角色将使 AI 角色看向主角色引用。
   2. 使用函数 `设置关注对象` 来设置当前正在谈论的是哪个对象，此函数还会自动将输入对象添加到环境中已存在对象的列表中。

角色蓝图可以是 MetaHuman、ReadyPlayerMe、Reallusion，甚至是你创建的自定义蓝图，只需确保它具有 `Convai 聊天机器人` 组件。
