I’m trying to make a tiled flash mapping programme using spatial averaging in AS2.

I have a function that fills the screen with random tiles.

I presumed that by running a second check where each tile checks its surround tiles and changes appropiately would work, but it only ever returns 3, 6 or 9 collisions regardless of the actual number.

Any ideas what’s wrong? This is what I tried:

function filterMap()  
{  
for (x = 0; x \< Stage.width; x += scale)  
{  
for (y = 0; y \< Stage.height; y += scale)  
{  
collisions = 0;  
for (j = -scale; j \<= scale; j += scale)  
{  
for (k = -scale; k \<= scale; k += scale)  
{  
if (tile[x + k, y + j] == tile[x, y])  
{  
collisions++;  
}  
}  
}  
if (collisions\< 6)  
{  
changeTile();  
}  
}  
}  
}
