Radial Action Billboard Gui Based On 3D World Mouse Position

[spice furnace]

Mouse.Move:Connect(function()
    local screenPos = Camera:WorldToViewportPoint(PlotBillboard.Adornee.Position)
    local dx = Mouse.X - screenPos.X
    local dy = Mouse.Y - screenPos.Y

    local angle = math.atan2(dy, dx)
    local degrees = math.deg(angle)

    Pointer.Rotation = degrees - 90
end)

so i want the pointer to rotate based on the 3d world position of the mouse and not by the screen. Anyone got any idea?

works slightly better

but the issue is still there

[steep oxide]

i'll need to set up a test for this

[spice furnace]

This is tech almost good

[steep oxide]

i can say with absolute certainty your math is fine (though i did have to negate dx and dy), the problem is the gui is not centered

local LocalPlayer=game.Players.LocalPlayer
local Mouse=LocalPlayer:GetMouse()
local Camera=workspace.CurrentCamera
local frame=script.Parent
local guiRoot=script:FindFirstAncestorOfClass("BillboardGui")

Mouse.Move:Connect(function()
    local adornee=guiRoot.Adornee
    if not adornee then return end
    
    local screenPos = Camera:WorldToScreenPoint(adornee.Position)
    local dx = screenPos.X-Mouse.X
    local dy = screenPos.Y-Mouse.Y

    local angle = math.atan2(dy, dx)
    local degrees = math.deg(angle)

    frame.Rotation = degrees - 45
end)```

hmm

I mean

it is centered

Lemme see

[spice furnace]

Now i can kinda see the issue

Mine is kinda flat, on the ground

I think i can fix it

if i have a cube floating on top of the plot

which can be used as the adornee

yeah lemme try that

that should work

[spice furnace]

@steep oxide Yep, works perfect now
