Alpha represents the transparency of a gui element. This function allows retrieval of a gui element's current alpha.

Syntax

float dgsDxGUIGetAlpha ( element dgsElement )

Required Arguments

  • dgsElement: The dgs element in which you want to retrieve the alpha of.

Returns

This function returns a positive integer in between 0 and 1 of the dgs element's current alpha, or false if it could not be retrieved.

Example

This example provides a guiFade function, which allows you to fade in/out a DGS GUI. 

DGS = exports.dgs
function guiFade( gui, state )
	if state == "in" then -- This state will fade in the DGS GUI
		fadeIn = setTimer(guiFade, 50, 1, gui, state) -- We loop the function to make it lower the alpha each 50 ms
		alpha = DGS:dgsDxGUIGetAlpha(gui) -- We get the DGS GUI's actual alpha after each loop
		DGS:dgsDxGUISetAlpha(gui, alpha - 0.1) -- We set the DGS GUI's actual alpha after each loop
		if alpha == 0 then -- If the loop reached "0"...
			DGS:dgsDxGUISetVisible(gui, false) -- We set the DGS GUI visibility to 0 so it won't be clickable or editable
			killTimer(fadeIn) -- ... We kill the timer
			fadeIn = nil -- And to make sure it doesn't exist anymore, we set it to nil
		end
	elseif state == "out" then -- This state will fade out the DGS GUI
		DGS:dgsDxGUISetVisible(gui, true) -- Since the GUI will still be click-able, we'll set it's visibility to "false"
		fadeOut = setTimer(guiFade, 50, 1, gui, state) -- We loop the function to make it higher the alpha each 50 ms
		alpha = DGS:dgsDxGUIGetAlpha(gui) -- We get the DGS GUI's actual alpha after each loop
		DGS:dgsDxGUISetAlpha(gui, alpha + 0.1) -- We set the DGS GUI's actual alpha after each loop
		if alpha == 1 then -- If the loop reached "1"...
			killTimer(fadeOut) -- ... We kill the timer
			fadeOut = nil -- And to make sure it doesn't exist anymore, we set it to nil
		end
	end
end

-- NOTE: If you're using a button to pop up the DGS-Element. Use "dgsDxGUISetEnabled" along with the button. You'll have also to set a timer in order to disable it by the time it fades, either way it will bug.
