How to display isometric maps with pytmx?

[michael1789]

Probably I could change these numbers, to make an isometric grid. But I don't know how to change them. Do you think that could solve my problem?

I don't think so. Looking at you pics, while the individual tiles are at the proper 45degree orientation, they are blit to the screen in a straight pattern across the screen. If we look at your isometric picture and take the top as the first tile, then the next is (x =+ TILESIZE / 2, y =+ TILESIZE / 2). But your program blits at x += TILESIZE. It's just writing them across instead of at the right angle.

nilamo, might be better help with deciphering the .tmx, but I can't read it.

I think the problem needs to be fixed here:

for x, y, gid, in layer:
                    tile = ti(gid)
                    if tile:
                        surface.blit(tile, (x * self.tmxdata.tilewidth,
                                            y * self.tmxdata.tileheight))

I really think there needs to be an offset figured out to put here

x * self.tmxdata.tilewidth + OFFESET

What that is would be the problem. It might be simple. Just to test the theory, try this and see what it looks like.

surface.blit(tile, (x * self.tmxdata.tilewidth / 2,
                    y * (self.tmxdata.tileheight * 1.5) ))

It think it will show a mess, but it might let us know we are on the right track. I suspect that in the end that the OFFSET will have to be a complex variable that tracks the rows and offsets the starting position, but who knows... that might fix it.
