GUI Click sequence?

Each time we click the button, something has to happen. You want to make X visible the first time, Y the second, Z the third.

That means you could just count which click we're on, and act accordingly:

local clickCount = 1
function click()
	if clickCount == 1 then
		X.Visible = true
	elseif clickCount == 2 then
		Y.Visible = true
	elseif clickCount == 3 then
		Z.Visible = true
	end
	clickCount = clickCount + 1
end

We could also interpret this as,

• if X is not visible,
  • make X visible
• otherwise
  • if Y is not visible
    • make Y visible
  • otherwise
    • if Z is not visible
      • make Z visible

This would eliminate the clickCount and also make it react to something hiding the frames / make this easier to "reuse"

function click()
	if not x.Visible then
		x.Visible = true
	else
		if not y.Visible then
			y.Visible = true
		else
			if not z.Visible then
				z.Visible = true
			end
		end
	end
end

We can shorten this using elseif of course:

function click()
	if not x.Visible then
		x.Visible = true
	elseif not y.Visible then
		y.Visible = true
	elseif not z.Visible then
		z.Visible = true
	end
end
