This function allows retrieval of a GUI element's current position, relative to its parent.

Syntax

float, float guiGetPosition ( element guiElement, bool relative )

Required Arguments

  • guiElement: The gui element of which you wish to retrieve the position.
  • relative: A boolean representing whether the position should be relative to the element's parent width, or an absolute pixel offset from the parent's origin.

Returns

Returns two floats of the x and y positions of the position of the element, or false if the position could not be retrieved.

Example

This example checks which corner a gui element exists in 

function positionCheck ( guiElement )
	local x,y = guiGetPosition ( guiElement, true ) --get the position
	local position --define the position
	if ( x == 0.5 ) and ( y == 0.5 ) then --if its bang in the middle
		position = "middle" --set position to middle
	elseif ( x > 0.5 ) and ( y > 0.5 ) then --if its in the right bottom
		position = "right-bottom" 
	elseif ( x < 0.5 ) and ( y < 0.5 ) then --if its in the left top
		position = "left-top"
	elseif ( x < 0.5 ) and ( y > 0.5 ) then --if its in the left bottom
		position = "left-bottom"
	elseif ( x > 0.5 ) and ( y < 0.5 ) then --if its in the right top
		position = "right-top" 
	else --if it couldnt be retrieved
		position = "unknown"
	end
	--announce this into the chatbox
	outputChatBox ( "The gui element's position is "..position.."!" )
end
