Topic: Build plots calculations change

I have tried to write a small lua script which count all building plots for a map loaded in editor:

map = wl.Editor().map

small_count = 0
medium_count = 0
big_count = 0
mine_count = 0

for x=0, map.width-1 do
    for y=0, map.height -1 do
        f = map:get_field(x, y)
        if f:has_caps('small') then
            small_count = small_count + 1
        end
        if f:has_caps('medium') then
            medium_count = medium_count + 1
        end
        if f:has_caps('big') then
            big_count = big_count + 1
        end
        if f:has_caps('mine') then
            mine_count = mine_count + 1
        end
    end
end

print("Amount of building plots:")
print("Small:  ", small_count)
print("Medium: ", medium_count)
print("Big:    ", big_count)
print("Mines:  ", mine_count)

If this script can be run over all maps automatically it should be possible to estimate the result of the proposed change.

But the result is surprising... for a map with 1 big plot, 4 medium plots, 2 mine plots and no immovables the result is:

Amount of building plots:
Small:          1
Medium:         5
Big:            1
Mines:          2

This might cause bottlenecks or similar bad side-effects on some official maps (Long Long Way) so we'd appreciate it if people who know the maps well could give their thoughts on which maps may need some editing to make them balanced again after this change

Is there any possibility to estimate how many building spots would be removed / added after the change? I am the "inventor" of Long Long Way and it should not be affected by that, but I would like to know how much it CAN be affected (by numbers of spots). Unfortunately it can be affected by the fact that port spaces calculation changed since map creation.

You could try something like this (...)

This will count the port spaces simply as big plots, but that should be fine for this purpose.

Yes, but it will not show how many plots will be missing with proposed change. Is there any possibility to check nearby nodes if they contain any lava / ice?

Yes, this can be done by checking the neighbores of a field

In order to show what's missing, you'd have to run this both with the master branch and the feature branch and then compare the results.

This was my idea... although it's a bit boring to open the debug console and type dofile('path/to/file.lua') each time a new map was loaded

This script seems to work properly now:

map = wl.Editor().map

small_count = 0
medium_count = 0
big_count = 0
mine_count = 0

for x=0, map.width-1 do
    for y=0, map.height -1 do
        f = map:get_field(x, y)
        if f:has_max_caps('mine') then
            mine_count = mine_count + 1
        elseif f:has_max_caps('big') then
            big_count = big_count + 1
        elseif f:has_max_caps('medium') then
            medium_count = medium_count + 1
        elseif f:has_max_caps('small') then
            small_count = small_count + 1
        end
    end
end

print("Amount of building plots:")
print("Small:  ", small_count)
print("Medium: ", medium_count)
print("Big:    ", big_count)
print("Mines:  ", mine_count)

I am compiling the nodacapsmath-branch now and will provide some comparisons later. Any special maps to compare?

Here are the results of the maps mentioned in the first post:

Map	Size	Branch master	Branch nodecapsmath
Long long way v2 (shipped)	Big	9178	9181

A bit strange: more big places than before?
Anyway, I will probably have to revise the map and fix it if needed .
