Absolute positioning and Custom Scale
 
I have a control centered horizontally on the screen. If possible, how would I vertically position this control at exactly 1/2 distance between the top of the screen and the center, and have this control stay there despite UI custom scale changes?

I would do
Lua Code:
  1. local height = GuiRoot:GetHeight()
  2. myFrame:SetAnchor(TOP, GuiRoot, TOP, 0, height/4)


/edit: if you want the center of your frame to be at that point, then do this instead:
Lua Code:
  1. local height = GuiRoot:GetHeight()
  2. myFrame:SetAnchor(CENTER, GuiRoot, TOP, 0, height/4)

Thanks! I'm using that inside a EVENT_SCREEN_RESIZED event, and it does the trick for screen resizing or Custom Scale changes.

Code:
EVENT_MANAGER:RegisterForEvent(name, EVENT_SCREEN_RESIZED, function()
    myFrame:SetAnchor(CENTER, GuiRoot, TOP, 0, GuiRoot:GetHeight() / 4)
end)

Clear your frame's anchor before setting a new one.

Ah, I just assumed it set over the old one. Thanks.
