Minecraft Java Edition – Using SOCKS Proxy for Minecraft

minecraft-java-editiontechnical-issues

Minecraft is very cool, much fun, but it doesn't appear to be listening when I tell it to use a SOCKS proxy for multiplayer connections.

In Java 8 (my version is 1.8.0_65), under section 2.4 of this page in the documentation, it says the following:

There are 2 system properties related to SOCKS:

socksProxyHost for the host name of the SOCKS proxy server

socksProxyPort for the port number, the default value being 1080

However, when running MC with the following options concatenated onto the end of the JVM arguments:

-DsocksProxyHost=127.0.0.1 -DsocksProxyPort=8080 -DproxySet=true

-Djava.net.useSystemProxies=true

It does not send the information through SOCKS. I have tested this server in Safari and it works just fine (external IP address changes). (note that this is using localhost as I run the SOCKS server in the background through a tunnel to an SSH server).

I've also tried manually starting launcher.jar with these options, but to no avail.

Am I missing something here?

This is a documented bug...

And it doesn't look like it's getting fixed anytime soon. However, I'm going to play with modifying the .jar file and edit this answer when I've found the solution through that method.

Minecraft Java Edition Commands – Using @e to Detect Item with Custom Name

Item and tag are not lists and display isn't a string, but Name is. And if you look at your supposed display "string", you see "Name", then a colon, then an escaped string, then another colon, then another escaped string. Both in NBT and in JSON, there's only ever one piece of text, a colon and a second piece of text, never three.

So in total, removing the square brackets from Item and tag and fixing the display stuff:

tp @e[type=item,nbt={Item:{id:"minecraft:polished_granite",Count:1b,tag:{display:{Name:"{\"text\":\"Block A\"}"}}}}] ~ ~1 ~

You can figure out these things by creating the item entity that you want and executing:

/data get entity @e[type=item,sort=nearest,limit=1]

It tells you all the NBT of the item. Now just copy that (I always leave the game log window open for something like that) and reduce it to the parts you need.
Alternatively, you can pay very close attention to the wiki's NBT lists (for example here (archive), because it does tell you the data type of everything (including if it's a list or not), it's just a bit hard to see, often it's only indicated by the icon on the left.
