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.

From the forge changelog: I would try downgrading your version of forge, as it appears it was built before these breaking changes were made. 1.15.1-30.0.15 would be my guess for the one this mod was built with, considering curseforge release date and forge update dates. The rendering stuff is going through a lot of changes in 1.15 from what I've read, so when encountering any kind of rendering errors, compare the mod release date and the release date of the version of forge you are using to see if there were any subsequent breaking changes. Good luck! =]

You should start your own thread and post logs, chances are your issue is not at all related to this one.

Where did you download your mods from? Some of your filenames suggest you downloaded from a bad website. I personally would only ever download mods from curseforge, or directly from the developers website. Sites that repost mods like 9 minecraft and such are bad, see https://stopmodreposts.org/ for more information. If you downloaded mods from any of the bad websites listed, I would delete them and redownload them from proper sources.

Make sure you have java installed, if so, likely jar files have become unassociated with it for some reason. There is an app on the web called jarfix that will correct this for you.

It would seem that immersive portals and chisels & bits 2 are both calling client classes, which will crash a dedicated server. Double check that there are not special instructions for server setup, and probably report to the mod authors.

So firstly, you have optifine for 1.8.9 trying to load in 1.12.2, which won't work, remove that old version, and get the one for 1.12.2 if you need it. (it almost looks like you have 2 copies of optifine in there with different filenames. Remove them all) It would also appear that you skyblockadditions mod is also for 1.8.9, remove/update that one. After these fixes, see what happens! Good luck, and Happy Holidays!

Better than nothing, if there's a debug.log that's probably even better.

Well one thing I noticed, you have iguanatweaks, and that is for MC 1.7, not 1.12.2.

Post logs as described in the EAQ, without further information it could be literally anything causing your issue.
