I am trying to make a custom crosshair feature in my game by pasting an images url ID into a textbox

Im getting this error and i dont know how to fix it: 18:04:33.863 Players.Moneyguy008.PlayerGui.Custom.Frame.Change.LocalScript:14: attempt to perform arithmetic (add) on nil and number - Client - LocalScript:14

I checked the dev hub and I didn’t find any solutions

If you know a way to do this please tell me

here’s the code

local button = script.Parent
local frame = script.Parent.Parent
local showcase = frame.Showcase
local textbox = frame.TextBox


local image = game.Players.LocalPlayer.PlayerGui.Aim.ImageLabel


button.MouseButton1Click:Connect(function()
	local url = textbox.Text
	print("image:", image)
	print("showcase:", showcase)
	local idStartIndex = string.find(url, "/asset/") + 7
	local idEndIndex = string.find(url, "/", idStartIndex) - 1
	local imageID = string.sub(url, idStartIndex, idEndIndex)
	local imageURL = "https://www.roblox.com/library/" .. imageID
	image.Image = imageURL
	showcase.Image = imageURL
end)

If you go to a page of an image using the roblox creator page and look at the url it will look like this: https://create.roblox.com/marketplace/asset/711250116/orange-bubble-trouble. i want you to be able to copy the number from it: 711250116. and paste it into a text box it will change an image label based on those numbers.

Ah, are you trying to make a custom crosshair system?

#5

yes, thats exactly what im trying to do.

#6

Okay, let me do something real fast.

#7 
local Icon 
local Players = game:GetService("Players")
local player = Players.LocalPlayer
local mouse = player:GetMouse()
TextBox.Changed:Connect(function(Value)
   if type(TextBox.Text) == "number" then -- is it a number?
       TextBox.Text = Icon
   end
end)
TextButton.MouseButton1Click:Connect(function()
    mouse.Icon = "rbxassetid://"..Icon -- you can just use TextBox.Text but you have to make sure it's a number.
end)

Which line of code does the error occur in? I have my suspicions…

#9

My bad, i realized the error is form another code.

#10

The error is: 18:04:33.863 Players.Moneyguy008.PlayerGui.Custom.Frame.Change.LocalScript:14: attempt to perform arithmetic (add) on nil and number - Client - LocalScript:14

#11

Are you trying to find the url of a number asset? Why can’t you just use local imageid = "rbxassetid://"..url
url can just be the asset id.

#12

Im trying to find the id from the link. EX: https://create.roblox.com/marketplace/asset/711250116/orange-bubble-trouble is the link and the id is: 711250116

#13 
local imageid = "https://create.roblox.com/marketplace/asset/"..assetid -- assetid is well the number id.

try this?

#14

That dosent work, if you read the error it something on line 15 with the -1

#15

You can get the first sequence of numbers in a string with string.match and string patterns

local imageID = string.match(url, "%d+")
