This tool was designed for scrap mechanic v0.4.0+ (Tested on v0.4.0-v0.4.7) So that we could easily share good map seeds by allowing others to view/modify map seeds. This is untested with creative saves, tool was created for survival saves

The seed tool has a graphical user interface, so that people without any programming knowledge can easily modify save seed's!

Download the ScrapMechanicSeedTool.exe and run it

or

Download the ScrapMechanicSeedTool.py Then run python3 ScrapMechanicSeedTool.py

Current Seed - This is the seed that will be used for all other options

Seed to use / Set seed - This is where you can change the current seed manually

Extract seed from save file - This option will prompt you to choose a save file so that it can set the current seed to the seed of the map

Modify world gen seed to be constant - This options sets the seed of ALL newly generated worlds to the Current Seed. Use this option to create a world with a specific seed!!

Reset world gen to default - This option will reverse the effects of modifying the world gen seed, so that it will no longer be constant.

Inject seed into save file - This option allows you to modify the seed of a save file. I added this features since dev tools give you the /recreate command which resets the world. I believe the seed is still being used for that command, I will attempt to try a bunch of different ideas. I would like to mention that I have no idea if changing the seed of the world after its already been generated works, this was added as an extra feature for testing purposes.
