Odds are once a moderator sees this thread, it will get locked, as these are just the forum rules (see LTS link at the top of the forums) I figured letting you know would get you a jump on seeking help for an old version elsewhere, instead of waiting around just to have your thread locked here. I wish you luck finding a solution!

It simply means that version is no longer supported by these forums, and threads asking for help will generally get closed, with a request the user update to a modern version (essentially the last 2 major versions, as of right now 1.14 and 1.15) Info on the versions supported can be found at the top of the page by clicking the "New LTS system" link.

You should not resurrect old threads because they seem to be the same problem as your own. Changes are good that the issue is different despite the symptoms appearing the same. That being said, 1.12.2 is no longer supported on these forums due to age. Update to a modern version (1.14.4+) to receive support.

If you just use %APPDATA% in your run command, can you find the .minecraft folder manually that way? Not sure if it would matter or not, but I'd also make sure to run vanilla MC first before installing forge.

1.7.10 is no longer supported on these forums because it is ancient. Update to a modern (1.14.4+) version to receive help here.

If you are using 1.14.4+, post your logs, if using a lower version, you will need to update to receive support here

Since these forums are supposed to be in English, here's the translation according to google translate:

No, you will still need to use packets when the data is updated; the events are only for players logging in, respawning, or changing dimensions, because during those events, I believe the player does not have the data, and will need it resynced/copied to them in those events.

Then those mods are fabric mods and will not work with forge. Remove them and try relaunching.

Do you have a pause at the end of your batch file? Are any server logs being generated? Post your batch file (not as an attached file, but as plain txt), as well as any logs that get generated. Unfortunately, there is not enough information in your original post to determine the problem.

Create a new thread, and post your logs. There are likely enough differences in your issues that yours is separate/different.

Delete all mods you downloaded from that site, and don't visit it. Redownload them from curseforge. I personally only download from Curseforge, or directly from the developers website (don't be fooled by fakes either!!!). Also, visit https://stopmodreposts.org for a list (the link to the list is at the bottom of the page on the left) of websites that you should never visit for MC stuff.

I guess now is the time to ask if you know Java? You were given examples to research (the HorseEntity and MinecartEntity in the vanilla source), as well as all the pieces you would need to code together to build the GUI you are talking about. This should be more than enough information to get started, and if what you try doesn't work, post your code on github as a working repository (i.e. so that it could be downloaded/built), and post a link here along with a detailed description of the issue.

You should create your own thread instead of reviving a thread that is 5+ years old. Chances are your problem is not exactly the same. That being said, 1.7.10 is no longer supported on these forums due to how old it is. You would need to update to a modern (1.14+) version for support here.

1.8.9 is no longer supported on these forums due to age. Update to a modern (1.14+) version if you wish to receive support here.

You are using worldedit for 1.14.4 with 1.15.1 Update the mod and see if that works

1.12 is no longer supported, you will need to update to 1.14+ to receive support on this site.

1.7.10 is no longer supported due to how old it is. You will need to update to a current (1.14+) version to receive support on these forums.

Add a line at the end of your batch file that says "PAUSE" (without the quotes), and it will wait for a keystroke after exiting before it closes the window.

Read the EAQ please, at the very least where it describes logs. :

Not doing so makes it harder to debug your issue, and a lot of people are "too lazy" to debug partial code.

Post logs as described in the EAQ next time you try to join the server and it fails, it might have a clue as to why it's happening.
