Make sure you are using Java 8. java -version at the commandline will show what version you are using.

I believe the issue tracker url can be whatever you want/have for an issue tracker address. The update JSON format I believe is this: https://mcforge.readthedocs.io/en/latest/gettingstarted/autoupdate/#update-json-format

The package names are pretty good, gui stuff will be in net.minecraft.client somewhere.

You should find the forge jar in the Referenced Libraries section of your IDE, it will contain the minecraft and forge sources. There is also a client-extra jar which contains model jsons and other client stuff.

Please start your own thread if you have an issue, this thread is nearly 2 years old. Also please note that 1.12 is no longer supported on these forums due to age. More information on supported versions can be found in the LTS link, at the top of every page.

Yeah, didn't notice it at first until I saw on github that the folders are separated by a slash, so the one with the dot was considered a single folder name. Glad it helped!

So it looks like perhaps your folder structure in your resources is broken a little bit, instead of being assets/mobfighters/models/item you have assets.mobfighters/models/item

Unplug any devices connected to your computer except the keyboard, mouse, monitor, and internet. Make sure there are no USB devices plugged in like bluetooth adapters or any other thing.

Yup, if you can host it on an external paste site and post a link here that's probably best, otherwise use spoiler tags

Please post your codebase as a github repository, it makes it much easier to read and see how things fit together. Also, please post complete logs, not just the lines you think are important. Spoiler tags (the eyeball button in the toolbar when creating a post) help make the thread not be 10 miles long.

When I need to figure something out, I search here and on google, and usually have good results. The vanilla minecraft sources are also a good reference on how to do things. You said you are new to modding, how familiar are you with programming in general, and specifically, Java? Without some prior programming knowledge, preferably in Java or a similar OOP language, you will not have a good time trying to mod.

It's not simply a matter of combining "scripts". You need to see and understand how vanilla minecraft makes a block "be 2 blocks tall", which is really *2* blocks, and when it grows, the bottom block checks if it has the top block, if not, it adds it when it grows. Since it has not been asked, it's up to me: Do you know Java? How much programming experience do you have? I can tell you that without some programming and/or Java experience, you will not have a good time trying to make a mod.

Weird, it looks like its complaining about SVEN X-PAD, whatever that is.

Unplug any extra controllers/devices connected to your computer.

In that case, please post your logs as described in the EAQ (first pinned post in the support forum). This will give us the information to help you

Having the mod installed on the server.

Based on that, I would say it's the Neat mod causing that error. Remove it, or make sure you have the correct version for the version of forge (not only version of minecraft) that you are using. I would also double check the list of mods you have, it almost looked like you had one in there for 1.12, which would cause issues for sure.

Post logs, and either share your codebase in a github repository, or I guess show a screenshot of your project layout in the IDE. This should provide enough info to figure out what's going on.
