myDisplay = textCreateDisplay ( ) -- create a text display
textDisplayAddObserver ( myDisplay, myPlayer ) -- make it visible to the player
x,y = textItemGetPosition ( otherTextItem ) -- get the position of 'otherTextItem'
if ( x == 0.5 ) and ( y == 0.5 ) then -- if the x and y of the text item are in the middle
textItemSetPosition ( otherTextItem, 0.5, 0.6 ) -- move otherTextItem down
end
myTextItem = textCreateTextItem ( "Hello world!", 0.5, 0.5 ) -- create a new textitem in the middle saying "Hello world"
