Split function, without a two walls on each side of the first and last window!

KennethLindhardt — Mon, 26 May 2014 13:16:57 GMT

I do not think that this is too complicated, but I seem to fail to get it to work like I would like.
I got my floors indexed into ground floor, first floor, sub floors and top floor. All of the floors needs to have needs to have tiles with ~4 in width. But the sub floors also need to have their tiles split once more, ~0.5 on the right side, and ~0.5 on the left side. But in the beginning and in the end, I do not want it to start with a ???sub split??? if this doesn???t make any sense, please have a look at the picture 😉
So what Im not able to do is to make the first and the last tile, to have only a split on one of the sites!

I believe I need to describe this a little more.
So each floor needs to have a an (x) split at the exact same place, be course I every tile needs to be aligned on top of each other.
Seperatly I can create a floor index and a tile index, but I fail to put those two together, so that everything not equal floorindex 0 && florindex == 1 should use my subdivided tile. For some reason the floorindex seems to get corrupted, when I try to use it again, after I have used my tileindex.
This is probably pretty easy; I guess I just am missing a link in my understanding. I have tried to put it together in many ways, but I think that this code is where I got closest to what I want, but still not at all where I want to be.

I got it, it???s working for me now. I provide the rule if any other is struggling with the same understanding issue as I did.
Maybe it could be done easier, so don???t hesitate with any comments. I???m here to learn 😉
