Are you able to send over the code? Would be useful for something I’m making
the one from the second video
local function MenuAnimation(Delta)
-- // Variables
local Viewport = Camera.ViewportSize
local Ratio = Viewport.X/Viewport.Y
local PixelPerStud -- This is set lower down
local MouseLocation = not UserInputService.MouseEnabled and Vector2.zero or Vector2.new((Mouse.X/ScreenGui.AbsoluteSize.X)*2-1,((Mouse.Y+36)/ScreenGui.AbsoluteSize.Y)*2-1)
-- // Raycasting
local TopLeft = Camera:ViewportPointToRay(PADDING,PADDING,DEPTH)
local TopLeftPos = (TopLeft.Origin+TopLeft.Direction)
local BottomRight = Camera:ViewportPointToRay(Viewport.X-PADDING,Viewport.Y-PADDING,DEPTH)
local BottomRightPos = (BottomRight.Origin+BottomRight.Direction)
-- // Math
local Diagonal = (TopLeftPos-BottomRightPos).Magnitude
local Y = math.sqrt((Diagonal^2)/(Ratio^2+1))
local X = math.sqrt(Diagonal^2 - Y^2)
local Size = Vector2.new(X,Y)
PixelPerStud = Viewport.X/Size.X
-- // Background
local XSize = Y*BackgroundSettings.Ratio
local Wobble = Vector2.new(math.clamp(Mapping(MouseLocation.X,-1,1,-1,1/((XSize/2+(PADDING*2)/PixelPerStud)/Size.X)),-1,1),MouseLocation.Y)*MAX_WOBBLE
Background.CFrame = (CFrame.new((TopLeftPos+BottomRightPos)/2+Vector3.new(Size.X*(NoticeTween.Value),0,0)) * Camera.CFrame.Rotation)*CFrame.new(-Size.X/2 + XSize/2,0,-PART_DEPTH/2) * CFrame.Angles(-Wobble.Y*(1-math.abs(Wobble.X/MAX_WOBBLE)),Wobble.X + MAX_WOBBLE/4,0)
Background.Size = Vector3.new(XSize,Size.Y,PART_DEPTH)
local ButtonSize = ((Size.Y*(1-BackgroundSettings.Header))-((BUTTON_PADDING/PixelPerStud)*(#BackgroundButtons+1)))/#BackgroundButtons
for i = #BackgroundButtons, 1, -1 do
local v = BackgroundButtons[i]
local mi = #BackgroundButtons - i -- Modified index, for messing with the position
v.Size = Vector3.new(XSize-(BUTTON_PADDING*2)/PixelPerStud,ButtonSize,PART_DEPTH/2)
v.CFrame = Background.CFrame * CFrame.new(0,-Background.Size.Y/2+v.Size.Y/2+BUTTON_PADDING/PixelPerStud +(ButtonSize+BUTTON_PADDING/PixelPerStud)*mi,PART_DEPTH/4+(PART_DEPTH/2)*((1-v.Tween.Value)*0.3)+0.1)
end
-- // Panel
if NoticeFunction then NoticeFunction(Ratio,PixelPerStud,MouseLocation,TopLeftPos,BottomRightPos,Size,BackgroundSettings,PADDING,BUTTON_PADDING) end
for i, v in ipairs(Panels) do
v["Function"](Ratio,PixelPerStud,MouseLocation,TopLeftPos,BottomRightPos,Size,BackgroundSettings,PADDING,BUTTON_PADDING)
end
end
RunService:BindToRenderStep("MenuAnimation",Enum.RenderPriority.Camera.Value+1,MenuAnimation)
This is the main math behind the 3D menu. This section itself is already a tad messy, the rest of the script is worse lol. Anyway, this is the important part
Also, change Mouse.Y+36 to Mouse.Y + GuiService.GuiInset.Height (or whatever it is)

the section to calculate the world position of the corners is so smart! good job and thanks for sharing

Hey! I know im like super late but honestly I feel like it looks natural that it goes away when you aim in. To be honest when the player is aimed in they want to be focused at what their shooting at and I feel like the UI going away actually makes it seem more immersive even though its technically a bug lol.

Mish and I recently made a module that simplifies this into oblivion:
daang, nice! you’re a legend, thanks for making it more accessible!
