Fake random seed
by xpncvr
Fake random seed lets a player type a fixed seed in world creation, so a new world is generated from that number instead of a random one.
What it does
When a new world is created, the seed box accepts a custom value and the mod applies it silently, so the world uses the typed number. The override takes effect only when the seed box is left blank; a seed typed by hand is kept as it is. Only numeric seeds are accepted, so the entry must contain nothing but digits. The mod is published for Fabric alone, for 1.21.4 and 1.21.10, and it runs on client and server.
Key features
Custom seed at creation
World creation uses a seed the player sets, replacing the random seed that would otherwise be generated.
Numeric seeds only
The seed box expects a number, so text entries are not accepted as the world seed.
Blank box keeps the override
A blank seed box falls back to the mod's custom seed, while a manually entered seed is left unchanged.

What the author says
This mod allows you to override the random seed on world creation and make the world always set your custom seed If you manually set a seed on world creation it wont override that, it only applies to random seeds (blank seed box)
