【框架设计】好友分组：自定义分组的社交管理框架

-- 好友分组：建组与归属
local player = class(actor)
local MAX_GROUP, GROUP_CAP = 10, 50
local function addToGroup(player, groupId, friendName)
    if groupId > MAX_GROUP then
        sendmsg(player, 1, 0, "分组数量已达上限 " .. MAX_GROUP .. " 个。")
        return
    end
    local memberKey = "GroupMember_" .. groupId
    local members = getplayvar(player, "HUMAN", memberKey) or ""
    local cnt = 0
    for _ in string.gmatch(members, "[^,]+") do cnt = cnt + 1 end
    if cnt >= GROUP_CAP then
        sendmsg(player, 1, 0, "该分组已满 " .. GROUP_CAP .. " 人。")
        return
    end
    setplayvar(player, "HUMAN", memberKey, members .. friendName .. ",", true)
    sendmsg(player, 1, 0, friendName .. " 已加入分组 " .. groupId .. "。")
end

-- 按组过滤：私聊路由与免打扰
local player = class(actor)
local MUTED = {["挂机组"] = true}
local function routeChat(player, fromName, text)
    local group = getplayvar(player, "HUMAN", "FriendGroup_" .. fromName) or "默认"
    if MUTED[group] then
        sendmsg(player, 1, 0, "【免打扰】" .. fromName .. " 发来一条消息。")
        return
    end
    sendmsg(player, 1, 0, fromName .. "：" .. text)
end
