Problem with creating a launcher for my forge server

Posted January 10, 201312 yr

Hi guys,

I come here because i think no one in the french community can help me .. ><.

I've a MinecraftForge Server and i try to make a launcher for my serveur, i actually did it but i got a problem,

i need to change in something in the client :

In minecraft.java :

public static File getMinecraftDir()

    {

        if (minecraftDir == null)

        {

            minecraftDir = getAppDir("minecraft");

        }

Everyone say i need to change "minecraft" with "name_of_the_server" so i take eclipse, MCP and forge source.

But i got these error when i add a mods after doing the modification even if i'm changing nothing i got the same error. The mod who i tried to add is NotEnoughItem and i control it i've no problem of versions or bad install of forge i just got all the time this error :

Why the hell are you doing it in such a stupid way?

Go look at MultiMC or any of the many many other launchers.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

And how i'm suppose to do whit launcher like MutliMc, to make a launcher who download the same mod I have on my server. That is not for playing minecraft forge lonely i need to make a launcher for the the server and I actually do it but i can't change where mods take place, i want them user the config file in the .name_of_my_server not in the .minecraft

As in, you look at how they launch minecraft, you write your launcher accordingly.

Read the EAQ before posting! OR ELSE!

This isn't building better software, its trying to grab a place in the commit list of a highly visible github project.

Don't PM me, I don't check this account unless I have to.

(((SOLVED))) Loading into certain worlds stuck on "Reading world data" then stops responding.

So, I tried this, and the world did load, but ALL of the modded items and things I had completely disappeared, as well as many unmodded things like my chests and items I was carrying. Any solutions?

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)
