[0.16.51] "seed" field in map-gen-settings.json not respected when using --generate-map-preview
Posted: Tue Oct 02, 2018 2:25 am
I am using --generate-map-preview on a headless Ubuntu 18.04 server, I am editing the seed field in map-gen-settings.json to get different map variations. When I specify "seed": 1 a new, random map is generated every time. When I specified "seed": 2, "seed": 3 or "seed": 4 the same map is generated for each of these seeds.
I expected to get a different, deterministically reproducible, map with each different seed but instead I get the same map unless I specify "1", which seems to mean random.
This issue seems to be similar but is distinct to these past issues:
[0.15.30] Map seed not working
[0.15.31] Linux headless server random map generation
I ran these commands to generate the previews (editing the seed field in gen-settings.json as appropriate):
These is the content of my gen-settings.json with seed 1:
Using Seed 1 (Try 2)
Using Seed 1 (Try 3)
Using Seed 2 (Try 1)
Using Seed 3 (Try 1)
Using Seed 4 (Try 1)
