Hi,

Stuck on this:
local buttonPos = go.get_position("#ButtonSTART") – No ERROR, but x & y are always 0 ?

function on_input(self, action_id, action)
	-- Add input-handling code here
	-- Remove this function if not needed

	local mX = action.screen_x
	local mY = action.screen_y	
	mX = mX * ( (360/WindowWidthTrue) )
	mY = mY * ( (640/WindowHeightTrue) )
--	label.set_text( "#MouseXY", "X:" .. tostring(mX) .. "/Y:" .. tostring(mY) )
	
	if action_id == hash("ClickGUI") then
		if CurrentScreen == 2 then
			local buttonPos = go.get_position("#ButtonSTART") -- No ERROR, but x & y are always 0 ?

label.set_text( "#MouseXY", "BX:" .. tostring(buttonPos.x) .. "/BY:" .. tostring(buttonPos.y) )
--buttonPos.x = 180
--buttonPos.y = 430

			local buttonWidth = (251/2)
			local buttonHeight = (38/2)
			if (  ( mX > (buttonPos.x - buttonWidth) and mX < (buttonPos.x + buttonWidth) ) and ( mY > (buttonPos.y - buttonHeight) and mY < (buttonPos.y + buttonHeight) )  ) then
				go.set("#ButtonSTART", "scale.x", 0.85)
				go.set("#ButtonSTART", "scale.y", 0.85)
				go.set("#ButtonSTARTText", "scale.x", 0.85)
				go.set("#ButtonSTARTText", "scale.y", 0.85)
			end
		end
	end
end

I am a slow learner, but very persistent…

go.get_position(“#ButtonSTART”) returns the position of the game object in which #ButtonSTART sits in (in this case), which is just (0,0,0), as that is where the game object Screen-2-Title sits. There is no way to get the position of a component in a game object.

You are trying to do GUI through game objects, which is nightmare fuel, as you can see below. There is a much, much, much better way to do it. Many people have already linked it before: the tutorial called Colorslide. Please check it out. Please.

Hi,

Thanks for the reply.
I’ll take a 2nd look at “Color Slide” tutorial…

Hi Again,

Our GUI buttons MUST animate, is that possible?
(button animation is simple scale down and scale back up)

Let us know before we jump into this (ie: “Color Slide” tutorial)

Thanks!

Maybe you should read the GUI overview before you continue? It outlines all the possibilities with GUIs.
