# GameOptionUI (P11) —— 游戏设置窗（1:1 迁移 `assets/root/uigameoption.py` `OptionDialog`）。

#   var go := preload("res://ui/game_option_ui.gd").new()
#   add_child(go)
#   go.setup(ui_manager, m2client, assets_root)
#   go.toggle()      # 由 system_menu_ui 的 game_option_button 打开
#
# 布局走真 `assets/uiscript/uiscript/gameoptiondialog.py`。绑定逐字对照 uigameoption.py：
#   block_{exchange,party,guild,whisper,friend,party_request}_button (toggle) →
#       `/setblockmode <mask ^ bit>`（EBlockAction 位：1<<0..1<<5）—— 真聊天命令
#   pvp_{peace,revenge,guild,free} (radio) → `/pkmode {0,1,4,2}` —— 真聊天命令
#   name_color / target_board / view_chat / always_show_name / show_damage / salestext (radio)
#       —— 客户端显示开关，持久化到 user://system_option.cfg [gameopt]；渲染节点按需读取这些设置。
