GetCursorPosition relative position

[vlakarados]

GetCursorPosition() gives you coordinates relative to BOTTOMLEFT part of the screen, how to make it show them from another position?

I've tried finding how I can get numbers similar to GetCursorPosition() ones with calculations of screen size and UI scale, something like

local hor, ver = strsplit("x", ({GetScreenResolutions()})[GetCurrentResolution()])
		print(hor .. " and " .. ver)
		print(hor/UIParent:GetEffectiveScale() .. " / " .. ver/UIParent:GetEffectiveScale())
		print(hor*UIParent:GetEffectiveScale() .. " * " .. ver*UIParent:GetEffectiveScale())

but it shows different numbers, currently I have 1280x1024 but this code gives me

[04:08:58] 1280 and 1024
[04:08:58] 1560.9756233719 / 1248.7804986975
[04:08:58] 1049.5999908447 * 839.67999267578

but GetCursorPosition gives me 1169.8 and 936.6 when divided with UIParent:GetEffectiveScale() when I put my mouse in the TOPRIGHT edge, so none of these numbers are correct...
My UI scale is 0.81999999284744

can someone please help me understand and find a way to do this?

That's because the units of UI object dimensions in WoW are not actually pixels.

Run:
/run print(UIParent:GetWidth(), "x", UIParent:GetHeight())

It won't say "1280 x 1024".

If you really wanted to use the resolution to place UI objects, you'd need to figure out the ratio of actual pixels (eg. screen resolution) to "WoW pixels" (eg. UIParent dimensions).

Thank you very much, you are a genius. I didn't have a good night sleep for a while so I'll blame that as a reason not thinking of this
No, I don't need the resolution then, I hope I will manage to make what I have in mind with GetWidth/Height then. Thank you very much again!
