You should make a new game directory for each version, and drop the mods in the mods folder itself. Also, don't download mods from sites like minecraftsix.com. Read this thread for the reason why.

You can try disabling the loading screen as described in the EAQ.

Post the FML log (logs/fml-client-latest.log in your game directory).

I misunderstood your question, I thought you were having a problem with rendering OBJ models bigger than 1x1x1. My bad. But yes, you do need to use 2 or more blocks for that. The bed item places its blocks in ItemBed#onItemUse.

This is known, and I don't think there's anything wrong. In Forge 1.12-14.21.1.2399, the missing language warning has been quieted down.

Override TileEntity#getRenderBoundingBox to return an AxisAlignedBB which corresponds to the size of your model.

First of all, please don't reverse the log. If anything, it makes it harder for us to read. Next, please run the game without Multicraft or change the rate limit. It might hide the crashing mod and crash log.

We can't know what other way is possible without knowing what you want to do. Now that I've read my previous answer again, I understand why it might sound weird. What I meant to say was: if we know what you want to do, why might be able to come up with another solution instead of registering during the game.

No, that is not possible. Why do you want to do that? There may be another way to do that.

Did you try running the launcher/game in administrator mode? If not, that might be the reason that the launcher/game can't access the file?

Yes.

When you download the mod, you should get a JAR file. Just place that JAR file in the mods folder, without extracting the contents.

Remove the JavaLegacyFixer, you shouldn't use it anymore. And it is not compatible with 1.11.2.

Try downloading the JAR installer, and run it from the command with the -Djava.net.preferIPv4Stack=true option.

-wrong-

I'm not insulting you, I'm just stating the obvious...

If you're having the same issue (not likely), this topic is fine. Any other issue needs a new topic.

No. No, no, no. You say you know Java. I don't think you do. We tell you to call the getRegistry method on an instance of RegisterEvent.Register. So you need to look around and see if there's an instance which you can use. Hint: it's the single parameter in the method. Then you need to call the getRegistry method on that specific instance. And apparently, that's too hard for you. You have a perfectly fine, working method commented out at the bottom of your Main class. Uncomment that and put it in a class annotated by @Mod.EventBusSubscriber.

RegisterEvent.Register#getRegistry() is a method. You need to call it like a method.

Ooorr... just use this.drawString, since you have access to it because you extend the Gui class.

Not an excuse.

I think using @ObjectHolder is the intended way of using registries, and seeing that every test mod using registries uses them @ObjectHolder, it would make sense to use it as well. Also, the docs say this is the recommended way.

Why would you want to shut the integrated server down? That doesn't sound like a good thing....

Post the FML log (logs/fml-client-latest.log in your game directory).

See the version dropdown? It is currently at the "Latest release (1.12)". Change it to a Forge version.
