I'm developing a tile-based scrolling game
with TileMapAtlas.

As pointed out in this group before,
there appear thin lines between tiles
and it's not a very good news for me.

I found that I can hide the line by
putting the same color as the edge of a tile
on the neighboring edge of tile to the next :
If a tile's right side was green,
paint the left side of the next tile green.

Doing like this of course is not a good solution
because it spoils neighboring tiles.
But guessing from this, by modifying TileMapAtlas to allow "offset"
to skip a few pixels between tiles will get the same result,
which will be a first-aid to this problem.

I, however, am new to cocos2d and I don't know
where to modify.
I even don't know if it's possible or not.
Somebody please give me advice ;)

Hey nekochan

I had an issue with lines between tiles too and the best solution for me was
switching to 2D Projection.  You do that with [[Director sharedDirector]
set2Dprojection]; after it's attached to the window.  Side-effect is 3D
effects and camera don't work so well.

My other problem was with "UV bleed" because in an atlas the float
coordinates for UVs are not too precise and some pixels/colour can bleed.
 You can try spacing the tiles on the graphic apart by 1px or painting an
extra border around the tile e.g. if the tile is 32x32 paint an extra border
to make it 34x34.

Search for alis/aliasing also.

Just some suggestions

I wasn't careful enough to find the update information
of TileMapAtlas in change log X(

But anyway, I have several codes to test with my current condition
and don't want to update cocos2d until it's finished,
So I've just tried Leto's idea first.
It worked fine!!
It's a nice quick-aid :)

After I've done my tests I'll update to v0.7.2 :)

Thanks!!
