【高级技巧】Lua树形遍历：沙巴克职级树奖励的递归下钻

local function grant(node)
    for _, m in ipairs(node.members or {}) do
        giveitem(m, "金元", 5, 0, "职级奖")   -- 只发一层
    end
end

local function grantAll(node, depth)
    local n = 0
    for _, m in ipairs(node.members or {}) do
        giveitem(m, "金元", 5 - depth, 0, "沙巴克职级奖")
        n = n + 1
    end
    for _, c in ipairs(node.children or {}) do
        n = n + grantAll(c, depth + 1)   -- 递归下钻全层
    end
    return n
end
sendmsg(actor, 1, "职级树共发 " .. grantAll(TREE, 0) .. " 份")
