You should update to the latest launcher, that thing looks ancient

I was messing with this a little myself, and made a little test thingy while I was playing with it. https://github.com/Ugdhar/structest

Looks like this is a function of some mod you are running, as forge does not change your jumping unless a mod is doing it. You will have to check what mods you have that affect the jumping/auto-jump, and either remove the mod, or see if they have a setting to turn it off.

So still looking into this, haven't figured a lot out yet or anything, but I've found some promising leads. I figured I would share here in case anyone else is looking into it, and it might help. It would seem net.minecraft.world.gen.layer.BiomeLayer is the layer class that is the most readable and also seems as though it does some biome setup using BiomeManager. It looks more or less like this is the "main biome setup", where the basic plains, forests, mountains are setup. At this point, I'm more or less thinking the required components are a BiomeManager, loosely based on the forge provided one; custom BiomeLayer to set things up, as well as other custom Layer classes (that actually don't even extend Layer class lol) for Rivers, Oceans, Hills, maybe Shores? And a custom LayerUtil replacement to build it. Once I have some code to share (that isn't huge copy pastes of the vanilla/forge code for figuring out how it works), I will certainly share a github link. Thanks for reading, and even more for posting if you have some insight!!!

What version is this for?

You are wrong. I do not know where you got your information, but structures definitely work, I made them work just in the past couple weeks. Sorry this thread is old, just replying because someone posted some incorrect information saying structures did not work. I made a simple structure test a few weeks ago messing around trying to figure out how to make it work, I only have a partial grasp on it, but feel free to check it out. Good luck, hope it helps you out! https://github.com/Ugdhar/structest

I haven't tried doing what you are doing or something similar yet, but I would say probably take a look at the furnace, and see how it renders the progress bar. I know your thing isn't a progress bar, but it should give an idea about rending an image based on a % of completeness (or, fullness).

What version are you developing for?

I would say at the very least to whitelist files.minecraftforge.net I am unsure of other addresses required (if there are any), I had thought there was a way to make the installer log verbosely, but I haven't been able to find out how in a few minutes of searching. Not sure if it will work, but you could try installing the server offsite, and then copying/zipping the server folder to a USB and copying it to the server, and see if that works.

I do not believe coremodding nor custom clients are supported on these forums. Please use Forge if you want support here.

Well, I'm not 100% sure, but the date on the mappings looked pretty ancient. The LTS link at the top of every page has the information on supported versions, although that may be changing soon with the impending release of 1.16

I would start a new thread, with a link to your code, as well as logs, considering it looks as if your previous thread was for a now unsupported version.

What about the code for those things that attack players that haven't slept? I believe they fly and attack with melee. Phantom I believe they are called. https://minecraft.gamepedia.com/Phantom#Java_Edition

Not overly helpful, we need the debug.log probably from C:\Users\P A S P A S\AppData\Roaming\.minecraft\logs

I think we need to see the debug.log, it should have more information than the crash report

Post the new log please

gist.github.com is the one I use, you may need to create an account if you haven't got one, I'm not sure since I've had a github for ages.

Choose an IDE and learn Java first. If you are unsure what the means, google "java IDE" and read some of what comes up. After you pick one, google "learn java using <NAME OF THE IDE YOU CHOSE>" and learn Java. Then you read the forge docs (link at the top of the page), and it will get you started. On your computer Download forge (I would go straight for the latest version) from the files link at the top of the page. Then go to https://www.curseforge.com/minecraft/mc-mods and search for mods. I would change the version dropdown to 1.15.2 to weed mods for old versions. When you find a mod you like, download it and put it in your %APPDATA\.minecraft\mods folder and they should load when you run the forge installation in your minecraft launcher. If you run into issues, come back here, and make a post in the Support forum section, and provide as much detail as you can about what you did, and what's going wrong. Post logs and exact error messages, not something like "It said it didn't work", because that's not a real error, and won't help anyone help you. Good luck, and have fun!

Make sure you read the Optifine changelog for the versions of forge it is compatible with. The changelog is on the optifine downloads page right next to the download link. Optifine is very specific about what versions of forge it works with.

Yeah I was looking at the old one, I'm sorry about that. You should post the debug.log on a paste site, it has more information than the crashlog.

*edit: Was looking at the wrong log this time around. And unfortunately, I can't tell which mod is broken, all I think I can tell is that one of them has a broken advancement or perhaps a malformed json

The filenames are wrong, the names of your files do not match the names of the files on curseforge, so unless you renamed them, they did not come from there. It may be that one of the sites that you got the mods from faked you out and made you THINK it was curseforge. I would not put that past the scumbags. I would just delete all the mods, and go back to curseforge, making sure to actually go to curseforge.com (and not google/bing/whatever for curseforge), and redownload them all. You will see what we mean by the filenames being different.

Make a github account, then use a github gist, that's how I share debug logs

It doesn't look like any of the assets are in that repo, so we can't see the blockstate for it.

Nope, it should be directly in the logs folder, and be called debug.log. In theory it would be C:\Users\nicol\AppData\Roaming\.minecraft\logs\debug.log Also, you can't post links to a local file like that, it will not open, it must be uploaded to an internet site.
