How to make several surface blocks in a biome?

The biome class has a genTerrainBlocks() method where you can do whatever you want.

Trying to boot MC Eternal 2 Server, works on linux not on Windows 11: Jvm args error

Make sure you are using Java 17 JDK

In the start script, replace the word "java" with the java 17 path (javaw.exe) and put it into quotation marks

NEED HELP ASAP - Failed to load datapacks, can't proceed with server load. You can either fix your datapacks or reset to vanilla

There are client-side-only mods in your server - start with removing justenoughbreeding

NEED HELP ASAP - Failed to load datapacks, can't proceed with server load. You can either fix your datapacks or reset to vanilla

Hey there, I have a big modpack I'm trying to run that I've put together with two other rather large communities- we have a grand opening scheduled for next week so it's really important that this gets solved ASAP.

The game runs fine in singleplayer, but when trying to run as a server using a hosting website, I've run into quite a massive error log. I've whittled it down to this point- I'm currently not sure what to do, as I believe the main error is relating to the datapack message, but I don't know for sure. Removing the datapack folder doesn't change the message either.

https://mclo.gs/2aTdXII

If the fix is something very simple, I apologize. I'm not too experienced with hosting websites and running large modpacks like this on a server.
I'm also not completely sure of which mods are client-only- a large handful of which are already disabled but I could be missing some. I just don't know which ones they would be, if that's causing the issue.

ok i have a early build of the mod there is lots more to come trust me @ggggggg453
https://drive.google.com/file/d/1q1L5fXqNy3aclCk74K0FeAn9FmJ15Byx/view?usp=sharing

its for forge 1.20.1 and go to the ingame mods tab and read the description for info

or just type in chat /orbital nuke 20 1
or /orbital stab 300 1

Trying to boot MC Eternal 2 Server, works on linux not on Windows 11: Jvm args error

Okay so I was trying to boot an MC Eternal 2 Server, I downloaded the latest server files from Curse which include a 47.4.2 jar. Whenever I install the server files into my folder and attempt to boot the server, I get Error: Could not find or load main class @user_jvm_args.txt in the cmd and nothing else. Now, MCE2 does have its own custom args so I deleted those and tried simple xms and xmx args, but that didn't let the server boot either. I assumed that maybe my java version was out of date, but I have the latest version of Java Installed and I even installed the Java 17 SDK for good measure just in case Java 25 is too recent for the pack. Still no avail. I tried running a vanilla 1.20.1 and it boots just fine, but for some reason the forge server still won't boot. Does anyone know anything I could try?
