用途

AI Girlfriend 行为引擎 — 为每个角色维护独立的关系评分、冲突状态、阶段状态、荷尔蒙状态。

核心文件

文件	用途
`engine.py`	状态读取/更新/保存的统一接口
`hormones.py`	荷尔蒙/生理周期计算（纯数学，不依赖LLM）
`conflict.py`	四级冲突系统
`stages.py`	9阶段关系系统
`behavior-tick.py`	行为决策层（每条消息的决策）
`online-tick.py`	在线/睡眠模拟
`daily-life.py`	每日作息生成

状态存储

每个角色的状态存放在 memory/role_play/<char>/relationship.json。

每次对话后，通过 engine.py 的 update_mood_delta() 方法更新状态。

使用流程

1. 读取当前状态

from skills.behavior_engine.engine import load_state

state = load_state("atori")
# 返回: { score, stage, conflict, hormones, ... }

2. 每条消息后更新状态

from skills.behavior_engine.engine import update_mood_delta

# LLM输出中的 moodDelta:
mood_delta = { "interest": 5, "trust": 3, "attraction": -2, "annoyance": 0, "cringe": 0 }

update_state("atori", mood_delta)

3. 获取行为决策

from skills.behavior_engine.behavior_tick import behavior_tick

result = behavior_tick("atori", incoming_text, context)
# 返回: { intent, delaySec, bubbles, reaction, shouldReply, ... }

moodDelta 字段说明

字段	范围	说明
`interest`	-100~100	兴趣度：对用户的兴趣和关注
`trust`	-100~100	信任度：对用户的信任程度
`attraction`	-100~100	吸引力：对用户的吸引力感受
`annoyance`	-100~100	烦躁度：对用户的烦躁程度
`cringe`	-100~100	尴尬容忍度：对尴尬/土味内容的容忍度

所有字段默认从 0 开始，负值表示负面，正值表示正面。

关键设计决策

每个角色独立状态文件，不共享评分
moodDelta 是统一变化入口，所有状态变化由此驱动
不依赖LLM的层（荷尔蒙、冲突）先用规则引擎判断
每5条消息检查一次阶段转换，避免每次消息都判断
