If you check the optifine changelog for the version you download (the link is on the optifine download page) it will tell you what version of forge, if any, it is compatible with.

Nope, it is all support, if it's before 1.14.4, there is no support here regardless of what it is for. There are just too many versions, and a choice had to be made what to support, and the current and previous versions are what was chosen to be supported. If I'm wrong, then this thread won't get locked by a moderator

1.12 is no longer supported due to age. Please update to a modern (1.14.4/1.15.2) version to receive support. More information on supported versions can be found in the LTS link at the top of every page.

Use Java 8, higher versions are not yet supported

I don't use it myself, so I don't know for sure, but maybe if you match up the version of optifine and the version of forge that it says it is compatible with (in the optifine changelog). This could then introduce the potential issue that the mods you want to use require a newer version of forge, then you may have to use older versions of them if available. Again, I don't use optifine myself, so this is purely speculation. *edit: And you should make your own thread if you have an issue, instead of hijacking someone elses thread

Really old versions are no longer supported, only modern (1.14.4/1.15.2) versions. See the LTS link at the top of every page for more information on supported versions.

Show your updated code whenever you change something and need more help Also, be more descriptive with your errors, does the code compile? Run? Does it crash? Is there a log? The more detail you provide, the less time people will have to spend asking you questions My suggestion when you are trying to do something, is to look through vanilla code for something that does something similar to what you are trying to do, and use it as an example. Find something that sets blockstates and look to see how it does it. Part of the problem I can see, is that you are not using setBlockState correctly. Where did you get your parameters from? I've never seen setBlockState used like that. Look at the method signature to see what parameters it wants.

When developing, use the latest version of the MDK, it has bugfixes and more current mappings out of the box. So is this the entire log, or did you leave some out? Just wondering if there was more after that.

No, curseforge is probably the only place on the internet I would trust to download mods, most other places are hosting without permission. https://stopmodreposts.org/ is the actual URL to the website you want to check out.

The jar installer is what you want, it is executable if you have Java and jar files are associated properly.

Please post your debug.log, it should have information in it that will explain what's going on.

Yeah, I can't help you with 1.7.10, it's no longer supported here, and I only work with current stuff myself, sorry.

With 1.15.2, import as a gradle project, then you should be able to run the genEclipseRuns gradle task after its done with the import.

You need to use Java 8

What version is this for?

How are you starting the server? Looks like you are passing invalid commandline arguments to it.

Don't download the launcher, use the installer. And here's a link to get Java: https://adoptopenjdk.net/ Make sure to get Java 8 Hotspot. *edit: also, just FYI, only 1.14.4 and 1.15.2 are supported here, so if you're trying for older versions, while they should work, you won't get any help from here with them.

I think they mean to say gait not gate.

That would indicate you are trying to download a modpack (which you would need the twitch client to install them) as opposed to individual mods.

I'm not 100% sure what you mean. You should now be able to create an installation (if one was not already created) in your Minecraft Launcher for forge, then download mods from curseforge.com and put them in the mods folder of the game directory (%APPDATA%\.minecraft by default unless you create a new one when you set up your installation).

Try Jarfix: https://johann.loefflmann.net/en/software/jarfix/index.html

Did you even read my reply to your other post? You shouldn't just create another post about the same issue. Do you have Java installed?

Just a thought (I haven't done any packet sending myself yet), you're sending the packet in the server start event, but are there even any clients connected at that point? Who is it sending the packet to? I'd check into that first!

I've never seen an error say "can't even open forge", you should post exactly what it says on the screen, or better yet, a screenshot, so there won't be confusion about what your actual error/problem is. After downloading forge, you should have an installer jar file, and double clicking it should open the installer program. If it does not, the next step is to make sure you have Java installed.

Make sure you are only installing Forge mods when using Forge. I see some fabric mods in there you will need to remove. Also make sure the mods you are downloading are for 1.15, I can't really tell just by looking if they all are or not. I would get rid of anviltweaks, it looks like it's broken or the wrong version or something, there's a bunch of errors for it in there.
