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

What version is this for? What happens when you try? Please post the debug.log, preferably on an external site like a github gist, and link to it here.

Have you done any research or worked on this at all yourself since your last posting? If you have, it would better promote your issue to share your findings/progress. I think people would be more attracted to your issue if they felt you were actively pursuing it!

Found some potentially useful example code in this repo: https://github.com/Tropicraft/Tropicraft/tree/1.15 (thanks tterrag, heard you mention Tropicraft and its worldgen while watching the FAP recording) Sad thing, been tinkering with all this stuff for the past few weeks/month whatever, and there's theoretically going to be a bunch of changes to worldgen in 1.16, soooo....yup. It'll be back to the drawing board once forge releases start coming out for that! More than likely I will start a new thread for that discussion with the new version/features/way of doing things/whatever. But, until then, or even after then (if 1.15.2 keeps support, which I imagine it will), feel free to pop in here with any tidbits of info or advice related to this stuff!!

If you know Java, look in the minecraft code at net.minecraft.client.renderer.tileentity.ItemStackTileEntityRenderer for how vanilla does it. If you do not know Java, then you need to learn some before you can write a mod, or you will have a Bad Time.

These mods are known to be very hacky. If you remove them and try it, does it still crash? If so, please post the new debug.log. If not, you know what the problem is!

Really old versions aren't supported anymore. They should still be usable, but no supported is provided for them. In order to receive support, you need to be using a modern version, currently 1.14+ The LTS link at the top of every page has more information on supported versions.

What version is this for? How did you install the server? How are you launching the jar? Does anything happen?

But your logs says:

Where did you download your mods from? Some of the filenames suggest you downloaded them from 9 minecraft, or some other rehosting site, that illegally redistributes mods, and often times have incorrectly labeled versions, or even modified/tampered with files. You should only ever download forge from https://files.minecraftforge.net/ and only ever download mods from https://www.curseforge.com/minecraft/mc-mods See https://stopmodreposts.org/ for more information on what sites to avoid. Also, it looks like you may have fabric mods installed, which will not work with Forge.

You should post your entire debug.log, and not cherry pick it as there can be things in there that could be related that you are omitting without realizing it. Also your textures/blocks folder should be named block instead of blocks (I believe this was one of the 1.13 rewrite changes). That could be why you were getting a missing texture at on point like you mentioned. *edit: and in your blockstate, you need to specify at least 1 state for the block, if there's no variants use empty "", and it must specify a model for that state, and you have empty curly braces. The vanilla blockstates, if you wish to reference them, are in the client-extras jar in your IDEs referenced libraries.

I am not completely sure to be honest, I've always kept my installations separate to avoid potential world corruption, so that wasn't a feature I myself used, sorry!

This feature was removed as the launcher installations are the preferred method of separating mods for different versions.

Are the folders those packages represent separated by slashes and not dots? Just want to make sure, I've seen them be made using the dots in the folder names, which breaks stuff. i.e the folder should be assets/ringsandthings, not assets.ringsandthings
