Possible to sort a table by a 2nd index?

[tobias1919]

I will try explaining this as good as i can...
Trying to build an addon to collect random roll results, and list them nicely with name, roll size, if roll is valid (1-100) and then sort the table, so highest roll shows at top.

I first thought collecting the rolls in a table:

local RollCollector = {}
function RollMaster:CHAT_MSG_SYSTEM(event, ...)
    local arg1 = select(1, ...)
    if arg1 then
        local name, roll, minRoll, maxRoll = arg1:match("^(.+) rolls (%d+) %((%d+)%-(%d+)%)$")
        for i = 1, 20 do
            if RollCollector[i] and RollCollector[i][1] == name then
                print(name.." rolled twice")
                roll = nil
            end
        end
        if roll then
            table.insert(RollCollector, 1, 0)
            RollCollector[1] = {name, roll, minRoll, maxRoll}
        end
    end
end

However, i'm not sure about how to sort a table like that (if even possible).

Then i thought about doing like 4 tables:

local RollCollector = { 
    name = {},
    roll = {},
    minRoll = {},
    maxRoll{},
}

and saving each arguement to its own table... But when running the table.sort method like this, it will only sort the rolls, which would remove the link between name and roll...

Anyone got a solution for this?


(Hope you understand the question, beside my rusty english!!)

Thanks alot on advance!

I don't think you need to sort the table, just keep it ordered as you add data

if maxroll<roll then
	maxroll = roll
end
if RollCollector[roll]==nil then
	RollCollector[roll] = {} --more than one person can roll the same number that is why the table
end
if minRoll==1 and maxRoll==100 then
	table.insert(RollCollector[roll],name)
else
	print(name,"is cheating")
end

to present

for i=100,1,-1 do
	if RollCollector[i] then
		for k,v in ipairs(RollCollector[i]) do
			print(i,v)
		end
	end
end

if you just want the highest then you just access RollCollector[maxroll] (which is a list of people that rolled the max, most of time just one person)

this is dry coded but I hope you get the idea.
