          Your problems can be solved by



          1. loading and using the positioning library and

          2. changing the non path.

          The first point means that e.g. below of= needs to go to below=<distance> of. The distance can be omitted in which case the node distance values get used. As for the second point, I used



          path[line] (whiletest.east) -- ++ (2cm,0) node[right] non |-
          ([yshift=-5mm]affect2.south) -- (output.north);


          where 2cm controls the distance, and you may adjust this to your likings. In addition I replaced tikzstyle by the corresponding tikzset syntax.

          • I should maybe add that tikzstyle and the positioning mechanisms that do not use the positioning library are really really deprecated. They should definitely not be used in any answer in the year 2019.

          • @projetmbc The above does not use "old cars", I think. You may make things a bit more automatic by using e.g. chains but this won't buy you much here. However, on the long run you will be way better off if you use positioning since its syntax is much more powerful.

          I just used your code and improved the requested things by just adding (-3,0) or (3,0) to your given positions. I think this is something easy to learn and can give you much more flexibility than creating the code from scratch -in my way- and instead of introducing just this simple thing to you.

          • I should maybe add that tikzstyle and the positioning mechanisms that do not use the positioning library are really really deprecated. They should definitely not be used in any answer in the year 2019.

          • @projetmbc The above does not use "old cars", I think. You may make things a bit more automatic by using e.g. chains but this won't buy you much here. However, on the long run you will be way better off if you use positioning since its syntax is much more powerful.

          Your problems can be solved by



          1. loading and using the positioning library and

          2. changing the non path.

          The first point means that e.g. below of= needs to go to below=<distance> of. The distance can be omitted in which case the node distance values get used. As for the second point, I used



          path[line] (whiletest.east) -- ++ (2cm,0) node[right] non |-
          ([yshift=-5mm]affect2.south) -- (output.north);


          where 2cm controls the distance, and you may adjust this to your likings. In addition I replaced tikzstyle by the corresponding tikzset syntax.

          I just used your code and improved the requested things by just adding (-3,0) or (3,0) to your given positions. I think this is something easy to learn and can give you much more flexibility than creating the code from scratch -in my way- and instead of introducing just this simple thing to you.

          • @projetmbc ... You was already using calc library, and I just wanted to add this answer to show you how to use it. Of course you may learn much more things, but with this one you already learn, you can do much things now. (Good choice your accepted answer and you can learn some more stuff there ... )

          I just used your code and improved the requested things by just adding (-3,0) or (3,0) to your given positions. I think this is something easy to learn and can give you much more flexibility than creating the code from scratch -in my way- and instead of introducing just this simple thing to you.

          • Interesting to see how to play with relative coordinates. Not so natural for me...
