New issue 198 by 2slow2ha...@gmail.com: [patch] TMX maps — tiles edges
misrendering
http://code.google.com/p/los-cocos/issues/detail?id=198

tiles.load_tiles() uses GL_CLAMP_TO_EDGE for proper edges rendering but
tiles.load_tmx() doesn't. I've modified a bit TileSet.from_atlas() to fix
it, see attachment.


Or you can use monkey-patch aswell

from pyglet import gl
from cocos import tiles

class TileSet_fixed_edges(tiles.TileSet):

@classmethod
def from_atlas(cls, name, firstgid, file, tile_width, tile_height):
image = pyglet.image.load(file)
rows = image.height / tile_height
columns = image.width / tile_width
image_grid = pyglet.image.ImageGrid(image, rows, columns)
atlas = pyglet.image.TextureGrid(image_grid)
id = firstgid
ts = cls(name, {})
ts.firstgid = firstgid
for j in range(rows-1, -1, -1):
for i in range(columns):
tile_image = image.get_region(atlas[j, i].x, atlas[j, i].y,
atlas[j, i].width, atlas[j, i].height)

gl.glBindTexture(tile_image.texture.target, id)
gl.glTexParameteri(tile_image.texture.target,
gl.GL_TEXTURE_WRAP_S, gl.GL_CLAMP_TO_EDGE)
gl.glTexParameteri(tile_image.texture.target,
gl.GL_TEXTURE_WRAP_T, gl.GL_CLAMP_TO_EDGE)

ts[id] = tiles.Tile(id, {}, tile_image)
id += 1
return ts

tiles.TileSet = TileSet_fixed_edges
