In order to animate a tile you simply modify the tile so it displays a different sprite

You would create a routine to go through your array and switch the tiles.

So if 1=water sprite 1 and 2=water sprite 2

make a routine to convert

.db 3,3,1,1,1,1,1,4,4
.db 3,5,1,1,1,1,1,3,4

To

.db 3,3,2,2,2,2,2,4,4
.db 3,5,2,2,2,2,2,3,4


You need to also create a routine that points the specific array byte you desire to change and simply load the new byte in.

and, ud need some kind of boolean var and when u switch the images, u switch the var... or, u could just check all the data for a 2 or a 3, and if it finds one, switch all of that one...

like so :
.db 3,1,3,1,3,3,3,3,3,1,1,1
it would search through that till it found a 3 or a 2, and when it found a 3, it would switch all of the 3's to 2's, and vice versa!

Which wouldn't work properly because you don't want that first 3 to be changed into a 2 (juding from Justin's code)

Well I use a counter, and if it equals a certain number it would switch to the first animation and if another switch it back so as to achieve a continuous loop.
