I believe your biggest problem is likely a lack of java knowledge. You really do need to know at least intermediate java/OOP in order to make mods for Minecraft. Otherwise you will struggle a LOT with the simplest of blocks and items, nevermind making anything actually cool/different/exciting. http://www.minecraftforge.net/forum/topic/49497-1112-is-using-registryevent-this-way-ok/ This post shows how to register items, blocks, and their models. If someone just writes the code for you and/or gives you the complete answer, you will be right back here stuck again unless you have some programming skills. I'm not trying to be mean, just stating what is true. There are a lot of guys on here that have been here a long time, and you won't get a nice answer out of them if you lack even rudimentary java skills, as this forum is not a place to learn how to program.

1.7.10 is no longer supported here, you are going to need to update to continue receiving support. Threads for versions that old tend to get locked fairly quickly.

1.6.4 is no longer supported here. Also, you made this post already once, were told it's not supported, and the thread was locked. Creating another thread for the same issue you were already told is not supported is likely to get you a warning from a moderator/admin to cut it out and to update if you want help here.

That. . .is very weird. I'm at a loss, unless your java's broken and needs to be reinstalled. I really am not sure without having logs to go by.

Please post your entire fml-server-latest.log file in spoiler tags (the little eyeball button above where you type your post), or upload it to somewhere like gist.github.com and link to it here.

1.7.10 is no longer supported here, you will need to update to a newer version for support.

Show us fml-server-latest.log

You will need to update for support, 1.7.10 is no longer supported here.

That says your blocks are being registered twice, not your items. If you look at the end of the initBlocks method: for(Block block : blockList) { event.getRegistry().register(block); } for(Block block : blockList) { event.getRegistry().register(block); } That's why right there, you do that loop twice.

1.7.10 is no longer supported here. You will need to update for support.

Post the whole fml-client-latest.log Make sure you're using the right version of abyssalcraft for the version of minecraft you're using.

We need the full fml-client-latest.log in your .minecraft/logs folder

1.7.10 is no longer supported

This post is over 3 years old, and 1.7.10 is no longer supported here.

1.7.10 is old and no longer supported, update.

1.7.10 is really old, and is no longer supported here. You will need to update.

please post the fml-client-latest.log from your .minecraft/logs folder

1.7.10 is no longer supported here, you will need to update to receive help. *edit: Your build.gradle is for 1.7.10, despite the subject line saying 1.12. If people help for 1.12, odds are it will probably not work in 1.7.10 since it is so old.

Read http://mcforge.readthedocs.io/en/latest/gettingstarted/ It explicitly tells you which files to move to your new project folder (steps 2 and 3)

First thing I noticed, is you do not need to use the AttachCapabilitiesEvent for a capability that is part of your own item, the initCapabilities method you overrode takes care of that. You would only use that event for attaching to an item that you didn't code yourself (i.e. a Stick or something) I haven't much time atm, so that's all I got for now, I'll look some more when I have more time.

It would be much easier if you uploaded your entire codebase to github Post all capability related classes otherwise pls (not to mention much harder to read code on here than github as well)

You should make all your registry names lowercase. You should set the unlocalized name using getRegistyName() after setting the registry name. Also, what version of Minecraft is this for?

If you're making a mod, post your code. You should also update from 1.8.9, it's getting old. If you're trying to use mods, one of them is a broken example mod.

I would say you could set those inside your item class if you wanted if they're the same for all batteries and wouldn't change per battery

You will likely get more help if you post your code on github instead of in a zip file. Not to mention version control is cool
