Custom projectile not being launched and only falls down through ground 1.10.2

Posted August 23, 20169 yr

I have registered the entity and the item, everything is rendered and the damage is working however when I throw my projectile, it just drops though the ground and is not shot out like a snowball, I have no errors i'm aware of if anyone could double check and help please.

Why don't you go back and look at what you may have copied this from.

ItemSnowball to be more precise.

It worked thankyou, I just needed to add the function public static void func_189662_a(DataFixer p_189662_0_)

{

EntityThrowable.func_189661_a(p_189662_0_, "copperknife");

}

in my EntityModKnife

}

in my EntityModKnife

The

EntityThrowable.func_189661_a

method (a.k.a

registerFixesThrowable

in newer mappings) does absolutely nothing. Adding a static method will also do absolutely nothing unless you call it from somewhere.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Im pretty sure what he actually forgot was to call setHeading (not sure if that is the name, but i am close).

Yes, I pointed this out in the OP's thread on Minecraft Forum.

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.

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.

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?
