This is still being worked on, so even if you cobble something together, there's a good chance it would break in the coming days/weeks while a dimension registration setup is designed/implemented. At the moment, from what I understand, there is only 1 very busy person that has the ability to do mappings stuff, so best thing is to just be patient, and they'll get updated eventually. There is a new system in the works that should make it much easier to update mappings, but again, people working on this for free when they have time, so we have to be patient. As 1.16.1 is still being worked on quite a bit, bugs being found/fixed, etc., there's not a definitive list of changes yet, I'm sure once things settle down, there will be. If you want bleeding edge info and discussion on the new version, I would suggest visiting the forge discord and seeing what's being discussed there.

Look for NBTExplorer (search google, it's a program someone wrote, I think i found it on the minecraft forums), it will allow you to open nbt files, or folders containing more than one, and browse/search through them. I've only messed with it a little, bit it should be what you need to help you find your box if you can find it in the file, you can probably get the position of it as well. There may be an easier way, or a way with commands, but this isn't something I've had to do myself, so am unsure of the different ways of doing it.

That is super weird, there are no crashes in those logs, they look like a normal startup. Is there a crashlog file in your .minecraft folder? Maybe try and cause the crash again and repost logs?

Please post your debug.log, preferably to an external site, and link to it here. It should have more information about what is happening.

It takes the same parameters as the way it worked before, except instead of creating a new instance of the class via new, you use the static create method.

The forums are a little glitchy, they're working on it Just dbl check if your post is there before you hit submit again Yes, in the .minecraft\logs folder, it might just be called "debug", if you're on windows and have (by default) file extensions turned off. It might be large, so you will probably want/need to post it on an external site like a github gist or pastebin or something and link to it here.

Is the loadComplete method running? I would double check via a log msg or breakpoint, just to be sure. Also, I've always seen oregen go in FMLCommonSetupEvent, not FMLLoadCompleteEvent. Probably doesn't matter, I would guess it's a nuance of the tutorial you're following.

Check out some of the vanilla classes that extend that same class, it looks like LoadingMessageEntry has some of them labeled. Sorry not more help, I haven't done much in the way of rendering myself.

What version is this for?

1.12 is no longer supported due to age. Please update to a modern version to receive support (I suggest the latest, esp. with 1.16.1 on the way). More information on supported versions can be found in the LTS link at the top of every page.

Use an external site to paste/upload it, such as https://gist.github.com/ (that's the one i use, if you prefer pastebin or one of those other things, go for it!) And I would still suggest trying to update your forge to the latest 1.14.4 version, it very well could help, not to mention there are other bug fixes and stuff in the newer ones.

It doesn't seem to tell in there, from what I can see. You could try posting the debug.log, it may have more information. Also, based on the same line numbers alternating throughout those errors, I would guess there's a chance it could be the recursion error fixed in forge 1.14.4-28.2.13 so you could try updating and see if that helps.

Try removing OptiFine and OptiForge, they are pretty hacky and could be causing your problem. If it still crashes, please post the new log.

it looks like the particles for the spawner are created in the net.minecraft.world.spawner.AbstractSpawner class. Check out how they do it there, in the tick() method as far as I can tell. Vanilla classes are a good reference for a ton of things

setupDecompWorkspace is not used in supported versions. Please update to a modern version to receive support. More information on supported versions can be found in the LTS link at the top of every page.

You typed the filename incorrectly, the file does not start with the word minecraft And you need to install Java 8 hotspot http://adoptopenjdk.net

Do not download the launcher, download the installer. If the installer does not work, please post the log (it will be in the same folder as the installer, after you run it, with the same name, but end with .log, possibly .jar if you are in windows and have file extensions turned off, which is the default I believe. But it will say it is a log file)

Have you tried something already? Are you trying to make armor like the vanilla armors, or armor with a completely custom model? I am not aware of any tutorials showing how to make armor items, however for vanilla-like armors, using the vanilla code as an example should be quite helpful. And then if it does not work as expected, post a link to code and logs here, with explanation of what's wrong. What about the classes (EquipmentSlotType and ArmorMaterial are actually enums) you mentioned are you confused about?

Please post your debug.log (pref as something like a github gist) and the code where you add your ore feature. Best way to share code is a github repository, if you aren't familiar with it, just google for a git/github tutorial, and start using it, you will not be disappointed! Great way to share code (just share a link to the github repository), and branches are great. Even if you don't plan on sharing your code or collaborating, using a git repository locally can save headaches and effort.

Looks like you might have some modid mismatches going on in some of your model/blockstate files

Always post the new log when that happens.

Post or look through your debug.log, there may be errors in there. Post your code as a github repository. There's obviously something wrong somewhere!

Please post the debug.log, it should have more information in it than the crashlog.

Install Java 8 Hotspot: https://adoptopenjdk.net

Post the new debug.log, or at the very least crashlog
