World Customization

This mod brings back the old World Customization Screen from Java, that was removed in 1.13 and is since never been implemented again, so I brought it back in a lightweight version.

Features

1. You can change the vein size, veins per chunk, minimum height and maximum height.
2. Block that can be changed are Ores, Stone variations, natural blocks like dirt or clay and all nether blocks or blocks that can spawn in nether like gravel.
3. You can change the spawning of things like trees or caves.
4. You can change fluid spawning in Overworld and Nether. (Cave modification is broken, keep this in mind when playing around with the settings)

Saving

The World settings will be saved in a JSON File, what basically means, you can create a world with whatever settings you want to have, and when you want to have them also in another world that has different settings, just open the world folder and replace the old settings with your new one.

Path: ".minecraft\saves\your world name\worldcustomizer.json"

IMPORTANT

Every Version besides 1.20.4 gives you the experimental warning when you want to create a world or open an existing world again. I tried to fix this, but sadly I found no working fix to remove this warning yet. So until a fix is available the mod will show a warning when you create a new world with the mod installed.

Planed Features

1. Presets for special worlds.
2. Saving settings directly in Screen
3. Syncing multiple sliders at the same time
4. MAYBE, adding structure toggles for villages, strongholds and so on
5. Other things like sea level MAYBE could be ported

Source Code & Credits

If you want to improve this mod, feel free to do so. Only thing I want is to get credited, nothing more. There are certain features from the 1.12.2 I will probably not port to my mod, as I don't want to touch the logic behind it. Sorry If someone wants the noise features back, I will probably not do it :=/

Old Features

Here is a visual for the part I WONT port to the mod myself.

Testing

I tested the mod with multiple worlds and I never had crashes. Only important to mention to water and lava generation can need longer, and performance can drop sometimes when generating a world with changed fluid settings. Just be careful.
