Plugins & Datapacks

Production-ready work built under the MrPumpkin name. Filter by type below.

Plugin

Dynamic Territory Control

The world is divided into claimable zones that factions or players can capture over time via King-of-the-Hill style presence. Each zone grants active buffs and can trigger live events.

  • Capture zones by holding ground over time
  • Zone buffs: money income, XP boosts, mob drops
  • Zone events: invasions & environmental hazards
  • Full API for third-party plugin hooks

Living NPC Economy

An advanced economy where NPCs simulate real supply and demand. Prices shift based on player activity — flood the market with iron and its value drops accordingly.

  • Dynamic pricing driven by player supply
  • Regional economies and trade routes
  • Custom NPC traders with personal inventories
  • Scarcity and abundance mechanics

Ship & Ocean Exploration

A fully-featured naval system. Buy, upgrade, and sail ships with real interiors, crew support, and cannon combat across a procedurally enriched ocean world.

  • Purchasable & upgradeable ship classes
  • Walkable ship interiors via portal system
  • Ocean gen with islands, bosses, and loot
  • Cannon mechanics & crew roles

Plugin

Adaptive Mob AI Overhaul

A complete rewrite of vanilla mob behaviour. Survival becomes genuinely dangerous — zombies coordinate, skeletons take cover, and creepers actually ambush.

  • Zombies track and group over long distances
  • Skeletons strafe and seek cover
  • Creepers use ambush pathing
  • Difficulty scales with player progression

  • Random layouts: undead, jungle, nether themes
  • Boss rooms with custom scoreboard mechanics
  • Loot tables scale with player progression
  • 100% vanilla-compatible
