Change the position of a Text+ node in Fusion depending on the comp's aspect ratio

repositionText.lua

:local w = tonumber( comp:GetPrefs("Comp.FrameFormat.Width"))
local h = tonumber(comp:GetPrefs("Comp.FrameFormat.Height"))
-- add the colon at the start of first line to allow multiline expression

if (w / h) > 1 then return Point(0.0, 0.0)
	elseif (w / h) < 1 then return Point(0.5, 0.5)
	else return Point(1, 1)
end

Copy and paste this straight into Fusion to see it in action.
