if ( x ~= 0.5 ) and ( y ~= 0.5 ) then --if the x and y of the text item are not in the middle
    myTextItem = textCreateTextItem ( "Hello world!", 0.5, 0.5 ) --create a new item for the display in the middle saying "Hello world"
    textDisplayAddText ( myDisplay, myTextItem ) --and add it to the text display
else --otherwise
