Ever wished you could create a custom play style, so your users do not copy the settings from the mod pack page?

Or you are a dev that wants to test world generation settings but need to copy and paste it every time.

This mod makes things easier, you can just change the worldconfig.json in the mod folder.

You should extract the mod from the zip. Just copy the folder from the zip into your Mods folder.

For that, you can create a World with your desired settings and then copy these settings.

After that, open the worldconfig.json file

Inside the file, there is the following entry:

"worldConfig": {
            "worldClimate": "realistic",
            "gameMode": "survival",
            "temporalStability": "true",
            "temporalStorms": "sometimes",
            "graceTimer": "0",
            "microblockChiseling": "stonewood",
            "polarEquatorDistance": "100000",
            "lungCapacity": "40000",
            "harshWinters": "true",
            "daysPerMonth": "9",
            "saplingGrowthRate": "1",
            "propickNodeSearchRadius": "6",
            "allowUndergroundFarming": "false",
            "temporalGearRespawnUses": "20",
            "temporalStormSleeping": "0",
            "clutterObtainable": "ifrepaired"
        }

Replace the contents inside the bracket with your desired settings.

Special Thanks to:
