# ChatManager.gd - 聊天系统业务逻辑核心
|
||
# ============================================================================
|
||
# 管理聊天功能的核心业务逻辑
|
||
#
|
||
# 核心职责:
|
||
# - 聊天消息发送/接收协调
|
||
# - 客户端频率限制（10条/分钟）
|
||
# - 消息历史管理（最多100条）
|
||
# - Signal Up: 通过信号和 EventSystem 向上通知
|
||
# - 整合 AuthManager 获取 token
|
||
#
|
||
# 使用方式:
|
||
# ChatManager.connect_to_chat_server()
|
||
# ChatManager.send_chat_message("Hello", "local")
|
||
# ChatManager.chat_message_received.connect(_on_message_received)
|
||
#
|
||
# 注意事项:
|
||
# - 作为自动加载单例，全局可访问
|
||
# - 遵循 "Signal Up, Call Down" 架构
|
||
# - 所有聊天事件通过 EventSystem 广播
