Fetching each of the current running game's thumbnails

Help and Feedback Scripting Support
#1

I have a menu, I want to show the thumbnails in a slideshow, how can I insert the thumbnails into a table, and then loop through them?

#2

This is on a ImageLabel by the way

#3 
local http = game:GetService("HttpService")
local getAsync = http.GetAsync
local jsonDecode = http.JSONDecode

local gameThumbnailsUrl = "https://games.roproxy.com/v2/games/%s/media"

local function getGameThumbnails(gameId, thumbnails, maxTries)
	gameId = gameId or game.GameId
	thumbnails = thumbnails or {}
	maxTries = maxTries or 5
	if maxTries == 0 then return end
	maxTries -= 1
	
	local requestUrl = gameThumbnailsUrl:format(gameId)
	local success, result = pcall(getAsync, http, requestUrl)
	if success then
		if result then
			local success2, result2 = pcall(jsonDecode, http, result)
			if success2 then
				if result2 then
					for _, thumbnailItem in ipairs(result2.data) do
						table.insert(thumbnails, thumbnailItem.imageId)
					end
					
					return thumbnails
				end
			else
				warn(result2)
				task.wait()
				getGameThumbnails(gameId, thumbnails, maxTries)
			end
		end
	else
		warn(result)
		task.wait()
		getGameThumbnails(gameId, thumbnails, maxTries)
	end
end

local gameThumbnails = getGameThumbnails(2938572470)
print(#gameThumbnails) --4
for _, thumbnailId in ipairs(gameThumbnails) do
	print(thumbnailId) --4 thumbnail IDs.
end

Here you go, I wrote this script which fetches the asset IDs of all thumbnails of a game.

Should I use the UniverseId or the placeId, and if I have to use the UniverseId, how would I get the it from the script?

#5

You need to use a universe ID, as it stands the script automatically uses the game’s universe ID if the function is called with no arguments.

#6

Well I mean like, getting the current universeId for the game during runtime.

#7 
gameId = gameId or game.GameId

That’s what this bit does, game.GameId gets the current universe ID.

I just tried it, my game has 3 thumbnails, but it returns 0. Any help?

These were outputted when inputting your game’s universe ID. Not sure where you went wrong.

#10

Huh, that’s odd, its now outputting the info.

#11

Wait, how can I add these to a folder through the server script?

I want to loop through them on the client.

#12

You’ll need to perform this on the server and use a RemoteEvent/RemoteFunction instance to transmit the thumbnail IDs to the client.

#13

Wait, can I use one RemoteEvent for all of this?

(sorry if you read the previous reply and was about give me a solution.)

#14

Yeah, the function returns a table of thumbnail IDs, you just need to transmit that table value to the client.
