组队邀请聚合：短时多次邀请合并一条

local function inviteBad(teamLeader, name)
    local p = getplayerbyname(name)
    -- 每条邀请单独弹窗，来十几条弹十几层
    sendmsg(p, 1, teamLeader .. " 邀请入队")
end

local function invite(teamLeader, name)
    local p = getplayerbyname(name)
    local list = getplayvar(p, "invList") or ""
    if string.find(list, teamLeader, 1, true) then
        return   -- 同一队长不重复入列
    end
    setplayvar(p, "invList", list .. teamLeader .. "|")
    setplayvar(p, "invT", os.time())
    sendmsg(p, 1, "收到 1 条新邀请，60 秒内合并展示")
end
