[2.0.76] --report-quantities didn't work as I expect

[vinaghost]

Or did it? (I'm not sure if this is a bug or not. If it is, can mod move it to Bug report, please ?)

While reading https://wiki.factorio.com/Command_line_parameters, I found --report-quantities
So below is my command

Code: Select all

"C:/Factorio/Factorio_2.0.76/bin/x64/factorio.exe" --generate-map-preview "E:\git\FactorioSeedFinder\preview-images\1002.png" --map-gen-seed 1002 --map-gen-settings "map-gen-settings.json" --report-quantities huge-rock

The huge-rock report is weird

Code: Select all

0.967 Info PlayerData.cpp:64: Local player-data.json available, timestamp 1778834973
   0.967 Info PlayerData.cpp:71: Cloud player-data.json unavailable

   2.098 Goodbye

while with other ore entity it displays correctly

Code: Select all

"C:/Factorio/Factorio_2.0.76/bin/x64/factorio.exe" --generate-map-preview "E:\git\FactorioSeedFinder\preview-images\1002.png" --map-gen-seed 1002 --map-gen-settings "map-gen-settings.json" --report-quantities iron-ore,copper-ore,coal,stone,crude-oil,coal

I can confirm this seed has huge-rock entity

p.s.: one small question, can we have it extracted to the file? (I mean, right now I can just read from stdout but it is nice if it writes to a file)

The question is not if the seed generates the entity but if the preview does. Can you confirm it generates in the preview?

It hard to see but you can see those rock here
