I'm relatively new to forge 1.12 and sort of new to minecraft modding in general. I wanted to make this mod so I could figure out how it all works. I'm having trouble figuring out why it throws a NoSuchMethod Exception. Does the server even keep track of ticking entities?

Of course it does. Why would the server--the authoritative source for all things--not know about ticking entities.

Your problem is that the function you're calling only exists on the client:

    /**
     * Updates the entity motion clientside, called by packets from the server
     */
    @SideOnly(Side.CLIENT)
    public void setVelocity(double x, double y, double z)
    {
        this.motionX = x;
        this.motionY = y;
        this.motionZ = z;
    }

If you want to modify motion on the server, just set the values directly. They're public.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

DO NOT PM ME WITH PROBLEMS. No help will be given.

So do I need to make a custom entity for this block when it explodes. Also when I did try to make a entity that extends EntityTNTPrimed, I was confused on weather I need to register a custom entity or if it's just registered when it's spawned. there is a class in com.dna.everythingisbad.entity

Yes and it can extend EntityTNTPrimed.

You need to register every entity that you want to exist in the world.

VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING

I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

Forge and vanilla BlockState generator.

Thank, you so much, I think it works now. But i'm just wondering why setVelocity is client side only.

It is used to update the motion of entities on the client-side.

It is used by packets from the server.

Some tips:

Spoiler

Modder Support:

Spoiler

1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.

Quote

Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.

Quote

The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it.

Support & Bug Reports:

Spoiler

1. Read the EAQ before asking for help. Remember to provide the appropriate log(s).

2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.

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.

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?
