2d camera. Billboard gui dissapearing. | Roblox Studio Community | Page 1

So i have an 2d camera system that works fine. But then i added a billboardgui on an ai thats moving and it dissapears after like 50 studs.

But then i tried disabling the camera scripts and it worked. The gui did not dissapear

So do anyone have a solution to this?
the script handling the 2d camera looks like this

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")

local player = Players.LocalPlayer
local camera = workspace.CurrentCamera

camera.CameraType = Enum.CameraType.Scriptable

RunService.RenderStepped:Connect(function()
local character = player.Character
if character and character:FindFirstChild("HumanoidRootPart") then
local root = character.HumanoidRootPart
local topDownPosition = root.Position + Vector3.new(0, 50, 0) -- height of camera
local lookAt = root.Position

    camera.CFrame = CFrame.new(topDownPosition, lookAt)
end

end)

#

Ive done alot of debugging

#

and nothing works

#

i figured out its has to do something with the script

#

but idk what

#

and i need to keep the script

-- In your BillboardGui setup:
billboardGui.AlwaysOnTop = true

#

If that doesn’t work

#

Use Camera:WorldToViewportPoint() to determine if the AI is in view, and then enabling/disabling the BillboardGui manually.

hoary mulch May 24, 2025, 11:19 PM

#

my billboard gui has had always on top for ages

#

it was the 2nd thing i tried

hold on

#

now it got complicated here 😭

#

how do i do allat?

glacial matrix May 24, 2025, 11:19 PM

#

Basically frustum culling on roblox is stupid

hoary mulch May 24, 2025, 11:20 PM

#

bro what

#

im not THAT good at roblox studio

#

sorry

#

can you explain it more begginer friendly?

glacial matrix May 24, 2025, 11:20 PM

#

Sure

#

1 sec

glacial matrix May 24, 2025, 11:21 PM

#

hoary mulch can you explain it more begginer friendly?

Roblox ui rendering = bad when it’s not exactly where it wants it to be

#

As it’s not connected to a camera object

#

It’s freaks out

hoary mulch May 24, 2025, 11:21 PM

#

uh okay

#

and how do i fix that?

glacial matrix May 24, 2025, 11:21 PM

#

local RunService = game:GetService("RunService")
local camera = workspace.CurrentCamera

-- Reference your AI and its BillboardGui
local ai = workspace:WaitForChild("YourAI") -- replace with your actual AI
local gui = ai:WaitForChild("BillboardGui") -- make sure this is correct

RunService.RenderStepped:Connect(function()
if ai and ai:FindFirstChild("HumanoidRootPart") then
local screenPoint, onScreen = camera:WorldToViewportPoint(ai.HumanoidRootPart.Position)

    -- Toggle GUI visibility manually
    gui.Enabled = onScreen
end

end)

#

Try that

#

In SS

#

(Starter player)

hoary mulch May 24, 2025, 11:22 PM

#

okay

#

wait should i make a new starter player script or replace the camera one i already have?

glacial matrix May 24, 2025, 11:23 PM

#

hoary mulch wait should i make a new starter player script or replace the camera one i alrea...

New

#

If that doesn’t work I’ll implement into your current script

hoary mulch May 24, 2025, 11:23 PM

#

ok

glacial matrix May 24, 2025, 11:23 PM

#

But it won’t work as well

hoary mulch May 24, 2025, 11:24 PM

#

still doesnt work...

studio ** You are now Level 2! ** studio

hoary mulch May 24, 2025, 11:24 PM

ive tried everything for over 2 hours 😭

glacial matrix May 24, 2025, 11:25 PM

#

1 second

hoary mulch May 24, 2025, 11:25 PM

#

but as soon as the camera script is disabled it works...

glacial matrix May 24, 2025, 11:25 PM

#

Delete that script

#

The one

#

I sent

hoary mulch May 24, 2025, 11:25 PM

#

yeah its disabled

glacial matrix May 24, 2025, 11:25 PM

#

hoary mulch

Scroll down on this for me

hoary mulch May 24, 2025, 11:26 PM

#

glacial matrix May 24, 2025, 11:26 PM

#

hoary mulch

Put the zindex up to 100

#

And

#

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")

local player = Players.LocalPlayer
local camera = workspace.CurrentCamera

camera.CameraType = Enum.CameraType.Scriptable

RunService.RenderStepped:Connect(function()
local character = player.Character
if character and character:FindFirstChild("HumanoidRootPart") then
local root = character.HumanoidRootPart

    -- Adjust camera height and rotation
    local cameraHeight = 50
    local cameraOffset = Vector3.new(0, cameraHeight, 0)
    local topDownPosition = root.Position + cameraOffset
    local lookDirection = Vector3.new(0, -1, 0) -- Looking straight down

    -- Look slightly *diagonally* instead of straight down to help BillboardGuis render
    local epsilon = 0.001
    local adjustedLook = root.Position + Vector3.new(epsilon, -1, epsilon)

    camera.CFrame = CFrame.new(topDownPosition, adjustedLook)
end

end)

#

Change your script to that

hoary mulch May 24, 2025, 11:27 PM

#

okay

#

it still doesnt work

#

idfk what to do 😭
