WoWInterface - Getting correct frame ui position.

Edit: Found the solution right after I posted. https://wowwiki-archive.fandom.com/w...CursorPosition

I needed to divide the cursor coordinates by UIParent:GetEffectiveScale(). Sorry about that!

I'm trying to figure out how I can get accurate screen coordinates for a frame.
In this example, I have my cursor at the bottom left corner of the red frame.

This is the script i'm using.

Code:

local f = CreateFrame("Frame", nil, UIParent)

f:SetWidth(400)

f:SetHeight(300)

f:SetPoint("CENTER")

f.texture = f:CreateTexture(nil, "BACKGROUND")

f.texture:SetColorTexture(0.43, 0.03, 0.03, 0.8)

f.texture:SetAllPoints(f)



f:SetScript("OnUpdate", function(self, elapsed) OnUpdateCallback(elapsed) end)

f:Show()



local dt = 0

function OnUpdateCallback(elapsed)

    dt = dt + elapsed

    if (dt < 0.1) then

        return nil

    end

    dt = 0



    local mouseX, mouseY = GetCursorPosition()

    print("Cursor: " .. mouseX .. ", " .. mouseY)



    local frameX, frameY = f:GetLeft(), f:GetBottom()

    print("Frame: " .. frameX .. ", " .. frameY)

end

Why am I getting different coordinates between the mouse and the bottom left of the frame?
