Subject: [PATCH] Support Overriding World Seeds
|
|
|
|
Allows you to add to paper.yml
|
|
|
|
seed-overrides:
|
|
world_name: some seed value
|
|
|
|
This will ignore every where a seed is set/created/loaded and force
|
|
a world to use the specified seed.
|
|
|
|
This seed will end up being saved to the world data file, so it is
|
|
a permanent change in that it won't go back if you remove it from paper.yml
