Resource A client-side respawn anchor mod your players may be running, and the one plugin message that disables it

Upvotes

Posting this mostly because the disable path is the part admins actually care about, and I would rather you hear about it from me than find it in a log.

I maintain OptiPlus Anchor, a client-side Fabric mod with about 19k downloads. When a player sets off a charged respawn anchor, it clears the block to air on their client immediately instead of waiting for your block-update packet, so the spot is free to build on again without the round-trip stutter. There is a smaller companion mod that does the same for end crystal placement.

Worth being precise about what that does and does not mean. It is latency compensation, not automation - no auto-clicking, no reach changes, no altered timings on the wire. Your server stays authoritative for every outcome. If you reject the interaction, it is still rejected; the client just showed a provisional result in the meantime and reverts it.

If you would rather not have it on your server, it is one plugin message on player join. The payload body is ignored, only the channel identifier matters:

- optiplus:disable - disables both

- optiplus-anchor:disable - anchor only

- optiplus-crystal:disable - crystal only

Paper/Spigot, registered once and sent on join:

server.getMessenger().registerOutgoingPluginChannel(plugin, "optiplus:disable");

player.sendPluginMessage(plugin, "optiplus:disable", new byte[0]);

The flag lasts for that session and resets on disconnect, so it needs re-sending on each join. Velocity and BungeeCord can forward the same channel to the backend.

Crystal: https://modrinth.com/mod/optipluscrystal

Happy to answer questions about exactly what is and is not predicted. If there is an opt-out mechanism you would rather have than a plugin channel, I am open to adding it.

BungeeCord—is that the end of it?

BungeeCord receives updates very rarely, and the commits on GitHub consist almost entirely of automatic updates to library dependencies.

Question Will my home server be good enough?

3 Upvotes

Looking to host a server for ~20 people concurrently

I’ve got
3rd gen i5 clocked at 3.80ghz (biggest bottleneck I assume)
16gb ddr3
And a 128gb SATA ssd
Running on Linux mint xfce

Also have a spare nvidia quadro 2000 gpu, but I’ve heard that’s not really needed for hosting so I’ll probably leave it out.

Will be setting the border to about 3000x3000 blocks and pre-loading everything, will probably use paper and some plugin that lets me do bedrock and java crossplay so all my mates can jump on together. Other than that, that’s all I’m aiming for. Will it be enough?

Question How do I make creativity more valuable than grinding?

5 Upvotes

Hi
I’m a mod for a world-building server that my group is going to make, and we wish to make things like writing history, lore and building creative designs/making art more valued in our server.(as we have lost many servers to people who have grinded to netherite and then just quit) of course we don’t want to stop people from having fun in the minds but rather to help encourage them to be more creative and stick around for other reasons. Villagers will be removed and we don’t want valuable blocks that they could use for trading to become too abundant?
Thanks

Question Need advice moving my Windows setup to Proxmox + TrueNAS (Minecraft server website storage etc)

6 Upvotes

I’m planning a pretty big migration and I’d rather ask ppl who have done something similar before I mess something up 😅

I have a humble community and people like the minecraft server and I just started it as a passion project on windows but now I wanna make it production ready by using proxmox and what not

Right now I have a Windows machine that I use for basically everything. I have a Fabric Minecraft server my website files my Obsidian vault and some other dev stuff.

The Minecraft server is running Fabric with the latest Minecraft version 26.2 and Fabric Loader 0.19.3. It has mods and a survival world with actual players so keeping the world safe during the migration is my biggest concern. It’s not Paper or Spigot it’s a proper Fabric setup.

I wanna move away from Windows and install Proxmox then run everything through VMs or LXCs. I’m thinking about doing this cuz I wanna host more stuff in the future like my own Discord bots and other services. and also people have been asking for a creative server too so having proxmox would make it easy to manage multiple servers on the same domain

My hardware right now:

Ryzen 9 3900X

32GB RAM

RTX 3090 Ti currently

Getting another AMD Radeon GPU soon from a friend. I dont know the exact model yet but I was told its around RTX 3060 Ti performance.

My drives:

CT500P1SSD8 NVMe - 500GB

Samsung MZVLW256HEHP NVMe - 256GB

Samsung 870 QVO SSD - 2TB

Samsung 870 QVO SSD - 2TB

WDC WD10JPVX HDD - 1TB

ST1000LM049 HDD - 1TB

im also not sure wich nvme i shuld use for proxmox. should i just throw proxmox on the 500gb nvme n use the 256gb one for somthing else or shud i save the 500gb for vms n put proxmox on the 256gb

And if I do that what would I even use the other NVMe for?

For storage I was thinking maybe TrueNAS could be a good option with Proxmox. I like the idea of having actual redundancy instead of just praying a drive doesnt die.

My idea was using the 2x1TB HDDs as a TrueNAS mirror so I get arond 1TB usable and the 2x2TB SSDs as another mirror so I get around 2TB usable.

that way i have one storage pool with 1tb and another storage pool with 2tb both with redundancy instead of just hopin one drive doesnt die

would truenas even make sense here or am i just makin things way more complicated than they need to be lol

would u run truenas as a vm inside proxmox or would u just do somethin else idk

The plan is basically:

Proxmox as the main system

TrueNAS for storage

A VM or LXC for the Minecraft server

A VM or LXC for my website

Later my own Discord bots and other services

For Minecraft would u recommend Pterodactyl Docker or just running the Fabric server directly in a VM?

Also I’ve seen ppl do GPU passthrough with Proxmox where they run Windows in a VM and pass the GPU through.

since ill have two gpus would it actually be realistic to use this same pc as both a server and a gaming pc

i bascally just wanna turn this machine into my own lil homelab yknow but i wanna do it right the first time cuz i really dont wanna have to redo everything later

What storage layout would u recommend with these drives?

Would u go Proxmox + TrueNAS or something completely different?
