addEventHandler( "onClientGUIMouseDown", root,
function ( btn, x, y )
if btn == "left" then
clickedElement = source; -- store the clicked element in a global variable
local elementPos = { guiGetPosition( source, false ) };
offsetPos = { x - elementPos[ 1 ], y - elementPos[ 2 ] }; -- get the offset position
end
end
);
addEventHandler( "onClientGUIMouseUp", root,
function ( btn, x, y )
if btn == "left" then
clickedElement = nil;
end
end
);
addEventHandler( "onClientCursorMove", root,
