So created a Sprite to which I add other Sprites which are game tiles.

So created a Sprite to which I add other Sprites which are game tiles. Each tile is 60 x 60 px big. In result I’ve the Sprite with about 200 childs (those tiles).
When I try to startDrag() the container sprite the lag when moving it is very noticeable..

Is there a way like to join the tile Sprites so the container would have only 1 child Sprite instead of 200? Because it lags so much probably cause it needs to move (change the x and y) all those 200 tiles.. Am I correct?

In this case I can’t use the cacheAsBitmap property, cause user can zoom in or zoom out the map..

    Glycerine & Aurel do touch the crux of the real solutions. However I’d like to add.

    You are correct by the way, when you said it has to manage so many sprite locations when you move the container around. CacheAsBitmap sure does does tackle this to great extent but the real solution is blitting. Try this link for that :

    It doesn’t matter if a user zoom or something of that sort is required cause you can always switch between bitmap data & the original vector sprites. Your problem arises in moving.managing lotsa sprites, so just before doing that use optimizations, after that let them be back to their selves.
