【入门夯实】清单还是账本：数组表与字典型表的处理差异

local ledger = { ["木材"] = 1200, ["石料"] = 800 }
sendmsg(nil, 1, "账本共 " .. #ledger .. " 条记录")

local function showLedger(actor)
    actor = getplayerbyname(actor)
    local ledger = { ["木材"] = 1200, ["石料"] = 800 }
    local cnt = 0
    for item, amount in pairs(ledger) do
        cnt = cnt + 1
        sendmsg(actor, 1, item .. " 库存 " .. amount)
    end
    sendmsg(actor, 1, "账本共 " .. cnt .. " 条记录")
end

local ledger = { count = 0 }
local function addEntry(item, amount)
    ledger[item] = amount
    ledger.count = ledger.count + 1
end
local function entryCount()
    return ledger.count
end
