  Hi Ale and welcome on board!!!
  hope you'll find Gideros SDK fine!
  
  i'm italian too (from l'aquila)
  for your scrolling problem (i don't know if i understood correctly your problem, but try this....)
  on desert demo modify function
  (no optimized but works...)
  
  -- ITALIAN MODE ON -------
  Ciao e benvenuto !
  spero ti piaccia Gideros sdk!
  
  per il problema che dici dello scroll prova a modificare questa funzione...
  (non so se ho capito bene il tuo problema... non vuoi che lo sfondo della mappa vada al "di fuori" dello schermo (e quindi si veda la parte bianca) ?
  
  attenzione non è ottimizzata... ma funziona!
  ciao
  -- ITALIAN MODE OFF -------

  local function onMouseMove(event) if dragging then local ScreenTilesW = application:getDeviceWidth() / map.tilewidth local ScreenTilesH = application:getDeviceHeight() / map.tilewidth local dx = event.x - startx local dy = event.y - starty if ((allLayers:getX()+ dx) < 0) and ((allLayers:getX()+dx) > ((map.width-ScreenTilesW)*map.tilewidth*-1)) then allLayers:setX(allLayers:getX() + dx) startx = event.x end if (allLayers:getY() + dy) < 0 and ((allLayers:getY()+dy) > ((map.height-ScreenTilesH)*map.tileheight*-1)) then allLayers:setY(allLayers:getY() + dy) starty = event.y end end end

  Hope it helps.
  
  Ciao Ciao
  Gianluca.

  Yes, that right and it works,
  but I need for a single image that I use as background.
  
  This is your code that I modify:
  
  [code]
  local function onMouseMove(event)
  if dragging then
  local ScreenTilesW = application:getDeviceWidth()
  local ScreenTilesH = application:getDeviceHeight()
  local dx = event.x - startx
  local dy = event.y - starty
  if ((bg:getX()+ dx) < 0) and ((bg:getX()+dx) > ((bg.width-ScreenTilesW)*bg.width*-1)) then
  allLayers:setX(bg:getX() + dx)
  startx = event.x
  end
  if (bg:getY() + dy) < 0 and ((bg:getY()+dy) > ((bg.height-ScreenTilesH)*bg.height*-1)) then
  bg:setY(bg:getY() + dy)
  starty = event.y
  end
  end
  end
  [/code]
  
  Best

  Ciao Gianluca,
  si hai centrato il problema,
  solo che a me basta applicarlo ad un immagine.
  
  Ho la mia immagine di BG
  local bg = Bitmap.new(TextureRegion.new(Texture.new("back.jpg")))
  stage:addChild(bg)
  
  su cui vorrei attaccare delle immagini.. e mi servirebbe che il bg non scompaia
  dall'area visibile
  
  
  Ho modificato la funzione un pò ma mi da errore
  
  [code]
  local function onMouseMove(event)
  if dragging then
  local ScreenTilesW = application:getDeviceWidth()
  local ScreenTilesH = application:getDeviceHeight()
  local dx = event.x - startx
  local dy = event.y - starty
  if ((bg:getX()+ dx) < 0) and ((bg:getX()+dx) > ((bg.width-ScreenTilesW)*bg.width*-1)) then
  allLayers:setX(bg:getX() + dx)
  startx = event.x
  end
  if (bg:getY() + dy) < 0 and ((bg:getY()+dy) > ((bg.height-ScreenTilesH)*bg.height*-1)) then
  bg:setY(bg:getY() + dy)
  starty = event.y
  end
  end
  end
  [/code]
  
  PS: tieni presente che ho visto LUA da solo 2 ore..
  
  Ciao
  Ale
