Hiding nameplates

[jojoza]

I'm trying to write an addon which would hide UI and nameplates and take a screenshot.

To hide nameplates, I use SetUIVisibility(). The problem:

SetUIVisibility(0)

hides nameplates,

SetUIVisibility(0);
Screenshot();

does not hide nameplates.

I'm assuming problem is mostly like that you're executing the two at the exact same time. This means that it's taking the screenshot before the nameplates are actually hidden. Try using an OnUpdate function to delay the screenshot by a half second or so.

Which OnUpdate? That OnUpdate which fires every time screen is drawn?

[Waverian]

Yes. Hidden frames don't call their OnUpdate script so you can use them to create a single-call delay on your screenshot.

local f = CreateFrame'Frame'
local last, throttle = 0, .5
f:SetScript('OnUpdate', function(self, elapsed)
	last = last + elapsed
	if last >= throttle then
		Screenshot()
	
		last = 0
		f:Hide()
	end
end)

Then just do

SetUIVisibility(0)
f:Show()

It worked! Thank you very much!
