Way to allow users to upload their own decals ingame?

Help and Feedback Scripting Support
#1

Hello! I was wondering how to let users input a decal ID and have it inserted into the game.
I’m making a game similar to Group Recruiting Plaza and want to allow users to upload a decal to their booth.
I’ve been doing a lot of looking on the DevForum and Wiki, but I can’t figure this out.

Any help appreciated

If it’s being handled from a TextBox that you can type in, you could probably handle RemoteEvents to fire the Decal ID sent from the client to the server & encase it in a pcall to check if the Decal ID is a valid ID or not & if it is you can insert it to their booth

That would require using InsertService - which requires that the game owner is the creator of the decal. I can’t insert the ID directly into a Decal instance, as it needs to be an ImageID.

You dont need to use insertservice to do set a decals id property

decal.Texture = "rbxassetid://"..userInput

When I run that:
Logo.Decal.Texture = "rbxassetid://"..logoid

I get this warning in the output and the decal doesn’t change:
Image https://assetdelivery.roblox.com/v1/asset?id=1522361034 failed to load. Error 403: Asset type does not match requested type

I’ve tried it with multiple decals

Thats not a valid image id
While the website id is A face! - Roblox the actual image id is 1522361030

Right, and that’s the issue I was having earlier.

Is there a way to get the image ID ingame, so users can use their own decals on the booth?

Doesn’t look like it’s possible

Dang, alright. Figured as much, just wanted to see if anybody had any other ideas, as both of those posts are a bit old.
Thank you!

If you have any experience with web development, there is actually a way to resolve a decal ID to the asset ID.

It’s very convoluted and requires you to make a httpservice request to your own server with the necessary code to process, but it is possible. The API you’d be looking at using if you went down that route is https://assetdelivery.roblox.com/v1/assetId/<id>

I should add, though, that asking player to provide a decal ID is poor UX in itself and should be avoided save for power users.

Ah, I thought you couldn’t use the Roblox API on Roblox. I’ll definitely try this out, thank you!
Everybody who is uploading decals is trusted in the community - about 30ish total. It’s a private game for a group.

You’re correct, you can’t use Roblox APIs with HttpService - as I said you’d have to have your own web server which then in turn requests the Roblox API and does some wacky stuff with the return from that API to determine the correct ID.

Figured out a way to do it using the code below.

function getImageID(scanOrgin)
	local result;
	local getItemInfo = game:GetService('MarketplaceService');
	local creator = getItemInfo:GetProductInfo(scanOrgin).Creator.Id;
	local assetT = getItemInfo:GetProductInfo(scanOrgin).AssetTypeId;

	if assetT == 13 then
		repeat
			scanOrgin = scanOrgin -1
		until getItemInfo:GetProductInfo(scanOrgin).Creator.Id == creator and getItemInfo:GetProductInfo(scanOrgin).AssetTypeId == 1
		result = scanOrgin
	else
		result = 'Not a decal!'
	end
	print("module", result)
	return result
end

return getImageID

Original code belongs to J_J - made some changes.

How it works:
Whenever you upload a decal to Roblox, it first uploads an image, then a decal. This script loops (using repeat) backward through IDs uploaded to Roblox and looks for any made by the same creator as the decal. Images and decals are uploaded milliseconds apart, so you don’t have to worry about accidentally getting a different decal from the same creator.

Input a decal ID as an int and since the image is uploaded before the decal, looping backward and finding an asset by the same creator will give you the image id.

*Again, credit to J_J for figuring the logic out!
