Make sure you have java installed, and if you do, run jarfix (google for it) once to reassociate jar files with java.

Did you run the installer? Are you using the latest mojang launcher? Was it closed when you ran the installer? More information please.

Try a Java version lower than 16

https://wiki.mcjty.eu/modding/index.php?title=YouTube-Tutorials I have no idea how good the video tutorials are, I can't stand the things myself, and stick to text only, but all reports say McJty is the way to go if you don't want to be taught how to do stuff wrong. Also, search the forums/use google, I've had lots of luck doing that when I wanted to figure out how to do stuff. Odds are, if you're asking it, someone else has probably asked it before you, and the answer is just buried in here somewhere. The pace at which the Minecraft code changes, which in turn forces forge to change, makes it tough for tutorials to be current, and they tend to get out of date somewhat quickly. Search a lot, try stuff, look at other mods code (tons of them are on github, just search on there too!), poke around in the vanilla MC code, and when the stuff you're trying doesn't work, post code (or much much better, a link to a working github repo of your code) and a description of what you're trying to do (from the player in-game standpoint, not what you want your code to do), and people tend to be pretty helpful (provided you indeed know basic/intermediate Java)

Post the full log (pref as a githup gist or something and link back to it here) please

Works for me. What's do you mean by "don't seem to be getting the correct file"?

And if you get rid of the Optifine and optiforge hacks does it still crash?

My guess would be just enough resources. If you remove that, does it still crash?

I would honestly delete that entire repo and recreate it correctly, that privacy issue is still there for anyone that wants to find it. Just trying to help keep ya safe buddy!

@joelstoner I sent you an important PM. Hopefully you get it.

Post your debug.log if it is crashing when you are trying to play. If it crashes when you are downloading mods, well, that's a computer issue, not a MC/forge issue, and you probably need a computer tech, or someone to help you.

I would highly suggest making a github repo for sharing your code, it makes it much easier to share, just a link instead of a wall of text. Had this link bookmarked from ages ago (yeah I don't clean out my bookmarks) when someone asked me about it: https://readwrite.com/2013/09/30/understanding-github-a-journey-for-beginners-part-1/

Always post new logs after you try something (*and it still doesn't work).

Try deleting this file and try again

Post your debug.log somewhere (i.e. github gist) and link to it here, it might show something that helps figure out what's up

Yeah, I would only download from the mod makers website, or curseforge, never any of the other shady MC sites out there. If in doubt, check on https://stopmodreposts.org/ and it will tell you if a site is to be trusted or not. As far as what versions of the mod work with which versions of forge/mc, I'm not sure. Can't hurt to try!

Where did you download that file from? That is not what it is named on crayfish's site, nor on curseforge.

Have you looked at the LootTable.Builder class to see if it has any useful methods for creating one? That's where I would start!

You should use github, and host your project on there, it makes it much easier to share your project with others. It's likely none of these files you posted here are relevant. If you dig through your project, you'll find FirstMod somewhere (besides a class name), I don't think the log would just change it to capitals if it were actually lowercase. Double check all your java files, and any jsons you may have created by hand. Also, you still did not share the full log.

I would wager the error is more related to your modid having capital letters in it And also, don't post single lines from a log, especially when you're a novice, the error isn't always where you think it is based on a single line of the log. Post the entire log, use a paste site like github gist or something.

Post logs, they might show what is going on

https://adoptopenjdk.net/?variant=openjdk8&jvmVariant=hotspot You might also want to uninstall the 32-bit JRE you have

You're running out of memory. You have a 32-bit Java by the looks of it, if you have a 64 bit system, get 64 bit Java. If you for some reason are actually running a 32 bit system, I'm not sure there is anything you can do besides upgrade, since 32 bit systems only support ~3GB max ram.

Currently Forge supports Java 8-15. There is nothing stopping you from having multiple JDK versions installed, as long as you are always referencing the proper version for the task. This will likely involve either specifying the full path to the java you wish to use and/or modifying your systems path environment variable. https://www.google.com/search?q=multiple+jdks+on+windows
