Help with a decal change gui

Help and Feedback Scripting Support

  1. What do you want to achieve? Keep it simple and clear!
    I want to be able to change the decal id or asset id on a tv.
  2. What is the issue? Include screenshots / videos if possible!
    I have tried multiple different scripts and all don’t work. This is mine so far.
local box = script.Parent;
local label = workspace.tvcart.TV.Screen.SurfaceGui.Frame.screen1;

local url = "rbxthumb://type=Asset&id=%i&w=150&h=150";

box:GetPropertyChangedSignal("Text"):Connect(function()
	if not tonumber(box.Text) then return; end
	label.Image = url:format(tonumber(box.Text));
end)

This is the Decal Change UI in server storage.

This is the tvcart and the surface gui with screen.

I’m pretty sure it’s because you’re trying to use the 2016 endpoint which has been deprecated:

You can find working thumbnail API’s here.

Might be a bit confusing at first, basically its a website that generates the links you’re looking for based upon asset type and more.

Code Fix (I think):

local box = script.Parent;
local label = workspace.tvcart.TV.Screen.SurfaceGui.Frame.screen1;

local url = "https://thumbnails.roblox.com/v1/assets?assetIds=%i&returnPolicy=PlaceHolder&size=420x420&format=Png&isCircular=false"

box:GetPropertyChangedSignal("Text"):Connect(function()
	if not tonumber(box.Text) then return; end
	label.Image = url:format(tonumber(box.Text));
end)
