Forge is safe, just make sure you ONLY download it from files.minecraftforge.net as anywhere else could tamper with the files, have outdated/mislabeled versions, etc. When downloading forge, *do not click on anything* after you click the download link for the file you want until the skip button appears in the top right of the download page, then click that. ONLY download mods from curseforge.com, there are a million pages that illegally host mods, and many of them have adware/spyware/viruses. Searching google for mods is dangers, because a lot of these bad bad sites have paid to get their pages put in the top results. Best way, just use curseforge.com it is safe. The issue with Pixelmon is that it is on an old version of forge that is no longer supported on these forums. If you use it and have troubles, you will have to ask for help somewhere else.

You should use Java 8 with Forge. And I do not believe you need a JDK unless you plan on developing mods, a JRE should suffice. Try running the installer from a terminal window, using java -jar <NAME OF FILE> If it fails, copy/paste the output here. If it runs, there should be an installer log file generated in the same folder as the installer, with the same name, except for .log at the end. If the installer does run, but fails during the install, post the contents of that file.

1.12 is no longer supported on these forums due to age. Please update to a modern version to receive support here. More information on supported versions can be found in the LTS link at the top of every page.

I believe you should be using loot tables. Here's a thread I remembered that's related: https://www.minecraftforge.net/forum/topic/74752-harvestdropsevent-not-working-as-expected/

Where are you downloading forge from?

Really old versions are no longer supported. 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.

I would say the only way to fix it would be to remove the mods from gottsch, or remove corail tombstone

You could try posting the latest.log, but I do not know if that would have enough information.

Ok, I would take a look at Daemonumbra's signature, under the logs section, where it says "Twitch Launcher", and perhaps try running the modpack through the vanilla launcher, and see if that makes a difference.

I honestly couldn't tell you, I've never run into this issue, hopefully someone that knows will see it and have some advice!

There is some information on rendering changes here, have you already seen it? https://gist.github.com/williewillus/30d7e3f775fe93c503bddf054ef3f93e

That's a newer log, but the errors are exactly the same, so I would say the original suggestion is still true.

None of that is the debug.log

That is the exact same crashlog, same date/time and everything.

Please host your logs on a remote paste site if they won't fit here; I'm sorry but I do not download .zip files from the internet unless I am 100% sure what they are.

Please post the debug log in the logs folder, it has more detail than the crash report.

I would suggest posting the new logs. It is possible that Java is no longer the problem if you have removed other versions. The logs will tell us what is actually going on.

Possibly, but I don't know for sure, I haven't looked for or seen anything I meant more that if your code was on github, it would be easier to see where the errors are. Also, what IDE are you using? I find it concerning that it didn't warn you about compile errors before attempting to run it anyway.

I don't think you want BipedModel there Your IDE should have given you an error about that, my workspace is 1.15.2, but I don't think they'd be that different. Also it is saying it has compile errors (which your IDE should have warned you about) because the super constructor you call doesn't exist. and this error happens in code that you didn't share: that's why a github is helpful Shows the big picture!

What kind of issues? Logs help, screenshots also if it's something visual. If you have your code on github that makes it easier to share/debug with other people too.

Ok, I think I see what you need to do, you need to put that in your FMLCommonSetupEvent , I believe using DeferredWorkQueue, because the biome stuff isn't threadsafe. If you search these forums for DeferredWorkQueue, I believe there's an example of how it's used. And the FMLCommonSetupEvent I believe is demonstrated in the examplemod that comes with the MDK.

You can use forge and mods on the Java edition of Minecraft even if your computer is running Windows 10. It does NOT work on the Windows 10/Bedrock version of Minecraft.

Well, you should have a basic-intermediate grasp of Java before starting modding, so you should be able to follow the code paths and see how features are set up. Think of what already happens in Minecraft that is similar to what you want to do, and look at the code for it. So find where, say, the flowers are setup in the plains biome or something like that.

I'm not sure about using IModel, I've never done that. When I was tinkering, the model I had just extended BipedModel<LivingEntity>. In the armor item class, used that model in the getArmorModel method.
