As the function copyImage is very slow and, anyway, doesn't work on android, I wonder how to realise a scrolling tilemap.

To map a dungeon map of 40x40 tiles (a minimum), i could theorically create a 1600 sprites and make a offset scroll over my map.
But I suppose that 1600 sprites are definitely too much for an android device...

So, do someone have an idea to realize that?
Thanks.

Mmm...
I've an Idea.

I create a 40x40 array of integer.
If the screen can display 10x10 tiles, I create 11x11 sprites corresponding to the displayed part of the map. (The part of the map which is under the "camera")
When I scroll over my map, example on the left, I destroy the sprites on the right which are not visible now and create new sprites to be seen on the left...
So I have always 11x11 sprites.

Mmm... That's a way to explore. I'm going to switch on my brain...

good idea. Instead of destroying/recreating (that takes a lot of CPU time) the edge sprites (and the internal sprites, too), someone has suggested to replace the frames associated to the tiles. At present I have not yet developed a tile game in AppGameKit (only in other languages e.g. Visual Basic and DarkBasic Pro), but some people in this forum are very experienced.
