Not finding Key in a Table

Help and Feedback Scripting Support
#1

I have this part of my script which I go through a table and if the player’s user Id matches one of the Id’s (key) in the table, it awards a badge:

for rank, d in pairs(data) do
		local name = d[1]
		local points = d[2]
		Id = tonumber(name)
		ranknew = rank
		print(Id .. " is ranked #" .. rank)
	end 

	local function speakerAdded(speakerName)
		local speaker = ChatService:GetSpeaker(speakerName)
		local player = speaker:GetPlayer()
		if player and player.UserId == Id and ranknew <= 20 and not badgeService:UserHasBadgeAsync(player.UserId, badgeId) then
			badgeService:AwardBadge(player.UserId, badgeId)
			print("awarded badge")
		end
	end

However, the part which is player.UserId == Id does not go through the keys of the table (the variable Id) and try to match it. What am I doing wrong?

You have a for loop which loops through everything and prints it once. After that you have a function. The function does not loop anything, instead if checks if a variable Id (which will have the value of the last pair in the loop) and ranknew which has the last key.

The issue I believe is that you loop it through once, but you don’t check for it when the function is called.

So i should place the function within the loop?

How can i check for every Id and not just the last one?

You could loop through everything first and create a new table which suits your needs better. You could the userId as the key and the rank as the value.

local rankTable = {}
for rank, d in pairs() do
	local name = d[1]
	local points = d[2]
	rankTable[tonumber(name)] = rank
end

The loop above will create a new table rankTable which has the format userid : rank. You may in your if-statement use rankTable[player.UserId] to get the rank of the player.

Thank you i will implement as soon as i get to my computer and circle back with the outcome.

This worked well… thank you for explaining and for the example, this is what the finished code snippet looked like:

	local rankTable = {}
	for rank, d in pairs(data) do
		local name = d[1]
		local points = d[2]
		rankTable[tonumber(name)] = rank
		print(tonumber(name) .. " is ranked #" .. rank)
	end 

	local function speakerAdded(speakerName)
		local speaker = ChatService:GetSpeaker(speakerName)
		local player = speaker:GetPlayer()
		if player and rankTable[player.UserId] <= 20 and not badgeService:UserHasBadgeAsync(player.UserId, badgeId) then
			badgeService:AwardBadge(player.UserId, badgeId)
			print("awarded badge")
			print(player.UserId .. " is " .. rankTable[player.UserId])
		end
	end
