Nested iterations

[Leslie]

Nested iterations can not work. In first sight this is a normal routine:

But LUA:

    local t = layout:getVehiclesOn(signal)
    for i, Iter in ipairs(t) do
      if Iter.variables["Park"] == 1 then
        Iter.variables["Park"] = 2

        -- Iter2
        local t2 = layout:getVehiclesOn($("Stop31"))
        for i2, Iter2 in ipairs(t2) do
          if Iter2.variables["Park"] > 1 then
            Iter.variables["Park"] = 1
          end
        end

These (2) corrections are hand-made and still not work.

Without correction all variables are equal, routine does not works at all.

I know this nested commands are not effective so I must re-think all.

But this requires a loud warning at the program for anybody to not use nest at iterations.

I see only one iteration in your screenshot.
With nested conditions ...

[Leslie]

Nested = inside of the iteration there is a second iteration.

This causes dysfunction at all time.

I know what a nested iteration is, Leslie
But your screenshot didn't show one.

Here's a nested iteration for you and it works as intended:

Kind regards

I missed that. Thank you, @Phrontistes

What is the actual problem with nested iterations? Please provide a sample layout which demonstrates any errors.

Kind regards,

My program caused bad result. I thought that same variables (i, t) cause this.

Later reorganized everything and now I have no nested iterations.
