## 获取善恶值对应的 40250 称号等级 (0..8)
static func get_alignment_grade(alignment: int) -> int:
	if alignment >= 12000:
		return TITLE_HEROIC
	elif alignment >= 8000:

## 获取善恶称号中文名
static func get_title_name(grade: int) -> String:
	return GRADE_NAMES.get(grade, "普通")

## 获取善恶称号颜色
static func get_title_color(grade: int) -> Color:
	return GRADE_COLORS.get(grade, Color.WHITE)

## 检查是否为红名（罪恶状态）
static func is_red_name(alignment: int) -> bool:
	return alignment < 0

## 检查是否为蓝名（正义状态）
static func is_blue_name(alignment: int) -> bool:
	return alignment >= 1000

## 40250 char.cpp:1197 在线自然恢复善恶计算
## minutes: 在线分钟数；has_fast_item: 是否佩戴禅定香囊等加速道具

## 击杀怪物增加善恶值 (40250 char_battle.cpp: UpdateAlignment)
## 击杀野外怪物根据怪物等级恢复善恶（红名时恢复极快）
static func on_kill_monster(cur_alignment: int, mob_level: int, player_level: int) -> int:

## 使用禅定豆 (Zen Bean 70102)
## 40250 原生逻辑：仅在红名 (alignment < 0) 时可使用，一次清除 500 点罪恶
static func use_zen_bean(cur_alignment: int) -> Dictionary:
	if cur_alignment >= 0:
		return {
			"ok": false,
			"code": "CANNOT_USE_NOT_EVIL",
			"msg": "你未处于恶名状态，无需使用禅定豆。"

		"msg": "使用了禅定豆，洗清了 500 点罪恶值！(当前善恶: %d)" % new_align
