Case Study

IceLegends SMP

A vanilla-first Romanian Minecraft SMP built for clean 3–4 month seasons.

The Problem

Running a community SMP means balancing plugin depth against vanilla feel, managing a world-reset cycle, and keeping operations simple enough for a solo admin. IceLegends SMP solves this with 11 carefully chosen plugins, strict feature gating per a "vanilla-first" principle, and fully automated backups and world resets.

My Role

Designed, configured, and deployed solo — server architecture, 11-plugin selection and configuration, LuckPerms permission model, economy and nation design, Docker infrastructure, and Cloudflare Tunnel ingress for Dynmap.

Join the Server ↗

Highlights

  • PaperMC 1.21 on Docker with a hard 11-plugin cap — every plugin is justified and none are redundant
  • Towny nations with seasonal quests (Quests + Citizens NPCs) and a single manually-spawned MythicMobs boss per season
  • AureliumSkills passive bonuses only — active abilities disabled to preserve vanilla combat (P-01)
  • DiscordSRV bridge logs every death, join, and chat event to dedicated Discord channels in real time
  • Daily automated backups with 7-day retention; resource world resets every Monday at 05:00 via cron

Constraints

  • Solo admin — every operation must complete in under 10 minutes (P-02).
  • Vanilla-first (P-01): if any plugin disappeared tomorrow, the game must continue unchanged.
  • 11-plugin hard cap — every addition must displace something or prove unique, irreplaceable value.

Key Trade-offs

The decisions worth defending — what I chose, what I turned down, and why.

Plugin count cap

Chose

Hard cap at 11 plugins

Rejected

Unlimited plugin stack

Each plugin is a maintenance surface and a potential conflict point. The cap forces prioritisation and keeps the dependency graph legible for a solo admin.

Public ingress for Dynmap

Chose

Cloudflare Tunnel (no open ports)

Rejected

Expose :8123 directly via UFW

No origin IP exposure, free DDoS protection, and zero firewall rule maintenance — the same pattern used by the IceLegends portfolio site.

AureliumSkills scope

Chose

Passive bonuses only, active abilities disabled

Rejected

Full AureliumSkills feature set including active combat abilities

Active abilities alter vanilla combat — a direct violation of P-01. Passive bonuses reward playtime additively without changing the combat model.

Season lifecycle

Chose

Full world reset every 3–4 months

Rejected

Incremental map expansion with no reset

Resets keep the world fresh, prevent terrain exhaustion, and give every new player an equal start — critical for community health in a small SMP.

What I'd Do Differently

An honest retrospective — the stuff I'd change with more time, more users, or a second pass.

  1. 1Add a staging compose stack so plugin updates can be tested before touching the live season — one bad update cost several hours of rollback work.
  2. 2Move backup storage off-site from day one; local-only archives are a single hardware failure away from a full season loss.
  3. 3Wire Dynmap as a named Docker service rather than relying on the host port, so the Cloudflare Tunnel config survives container IP reassignment on restart.

27 — ImageOnMap — Imagini custom pe hărți

"

Steaguri de națiuni, logo-uri, artă custom pe hărți fizice în joc

#De ce e interesant

Jucătorii pun URL-ul unei imagini și primesc o hartă fizică în joc cu acea imagine. Națiunile își fac steaguri custom, bazele primesc tablouri personalizate, se pot face hărți tematice cu logo-ul serverului.

#Download

Sursă:   github.com/SebCodesTheWeb/image-on-map-reloaded
Licență: GPL-3.0 — gratis
Impact vanilla: zero — harta e un item vanilla

#Cum funcționează

1. Jucătorul are o hartă goală în inventar
2. /image URL_imagine    ← pune URL-ul imaginii
3. Pluginul descarcă imaginea și o renderează pe hartă
4. Jucătorul primește harta cu imaginea
5. Pune harta într-un item frame pe perete
