保存lua表中的字符串索引(数组或字典表?)

标签: indexing lua lua-table

所以我陷入了两难境地。我有一个代码读取某个msg,例如:

m.content:sub(1,8) == 'Loot of ' then

读取:

01:50 Loot of a starving wolf: a dirty fur, a salad, 2 pancakes, 60 gold

现在我正在尝试将其插入表格中。到目前为止我遇到的问题是我无法计算字符串的类型并在表中对它进行比较以添加其索引。

例如:

t = {dirty fur="quantity of msgs that show this",insert a new msg="how many times haves appear}

到目前为止我的工作是:

foreach newmessage m do
m.content:sub(1,8) == 'Loot of ' then

然后我就迷失了。我不知道如何创建这个表;它应该是本地的,我相信,但我遇到的主要问题是我不想成对打印它,我想按照它们插入的顺序将值从1调用到#table。这就是我的痛苦开始的地方。

我想要类似的东西:

table msgs = {spear='100',something='2', ovni='123'}

所以当我得到这个表(我仍然无法制作)时,我可以为同一个表调用另一个函数,我想调用表。“xmsg”=数量。我希望有人理解我的要求。

function loot()
foreach newmessage m do
        if m.type == MSG_INFO and m.content:sub(1,8) == 'Loot of ' then
        local content = (m.content:match('Loot of .-: (.+)')):token(nil,', ')
        for i,j in ipairs(content) do
       return content
         end
      end
   end
end

返回此函数的消息:

{"3 gold coins"}
{"3 gold coins"}
{"nothing"}
{"6 gold coins", "a hand axe"}
{"12 gold coins", "a hand axe"}

TEST_LOG = [[
01:50 Loot of a starving wolf: a dirty fur, a large melon, a cactus
02:20 Loot of a giant: a large melon, an axe
03:30 You are on fire! Not really, this is just a test message
04:00 Loot of a starving wolf: a dirty fur, a tooth, a bundle of hair
04:00 Loot of a starving wolf: a dirty fur, a tooth, an axe
]]

ENEMY_LOOT_COUNTS = {}
LOOT_COUNTS = {}

for line in string.gmatch(TEST_LOG, "([^\n]+)\n") do
    local time, msg = string.match(line, "(%d%d:%d%d) (.+)$")
    if msg and msg:sub(1, 8) == "Loot of " then
        local enemy_name, contents = string.match(msg, "^Loot of a ([^:]+): (.+)$")
        local enemy_t = ENEMY_LOOT_COUNTS[enemy_name]
        if not enemy_t then
            enemy_t = {}
            ENEMY_LOOT_COUNTS[enemy_name] = enemy_t
        end
        local items = {}
        for item_name in string.gmatch(contents, "an? ([^,]+)") do
            items[#items+1] = item_name
            enemy_t[item_name] = (enemy_t[item_name] or 0)+1
            LOOT_COUNTS[item_name] = (LOOT_COUNTS[item_name] or 0)+1
        end
    else
        -- you can handle other messages here if you want
    end
end

for enemy_name, loot_counts in pairs(ENEMY_LOOT_COUNTS) do
    local s = "Enemy "..enemy_name.." dropped: "
    for item_name, item_count in pairs(loot_counts) do
        s = s..item_count.."x "..item_name..", "
    end
    print(s)
end

do
    local s = "Overall: "
    for item_name, item_count in pairs(LOOT_COUNTS) do
        s = s..item_count.."x "..item_name..", "
    end
    print(s)
end

我想写一个很长的答案来附上这段代码,但我现在没有时间,抱歉。 我稍后会这样做。
