GlobalWarming- - Supports Minecraft 1.14+

Minecraft Server Java Edition (Spigot) plugin which adds game-changing climate change mechanics.

Table of Contents

Contributing

  • Developer Setup
  • There is a Kanban board on Github where I'll be prioritizing work, feel free to help work on any of the tasks.
  • Pull requests welcome! This is a very new project and I appreciate contributions.

Overview

  • Adds the concept of greenhouse gases (CO2) in the worlds atmosphere
  • Furnaces emit CO2 when players smelt items
  • Farmed Animals emit CH4 when they are killed
  • Trees (instantly) absorb CO2 when they grow from a sapling
  • As CO2 levels rise, global temperature rises because of the Greenhouse Effect

Purpose

  • Ever had the hankering to turn a game meant for fun into an emulator of one of the modern world's toughest challenges?
  • Observe the Prisoner's Dilemma first hand!
  • Players are best off when they co-operate and agree to reduce their emissions
  • However, each player typically believes they are better off for themselves to emit as much as they wish.
  • Avoiding a Tragedy of the Commons might be fun! If the players don't play nice and end up dealing with the consequences, they might decide to agree to fix the planet.

Mechanics

  • Every furnace burn causes a "Contribution" to emissions with an associated numerical value (based on the model)
  • Every tree growth causes a "Reduction" from emissions with an associated numerical value (based on the model)
  • The global temperature is a function of the net global carbon score.
  • As the global temperature rises, the frequency and severity of negative climate damages increases.
  • Players can purchase "carbon offsets" which creates a tree-planting bounty for other players to fulfill.

Challenges

  • Designing a default model that doesn't quickly destroy worlds
  • Efficiently applying in-game mechanics changes

Features

  • Scoreboard Integration - Players can compete for carbon neutrality! The worst polluters can be shamed.
  • Economy Integration - Set up tree-planting bounties
  • Carbon Scorecard - Each player can see their latest carbon footprint trends via the command line.
  • Multi-world - Associate emissions in the end or nether worlds to the primary overworld with ease.
  • Custom Models - The inner numerical workings are as configurable as possible. Set thresholds, probabilities, and distributions.
  • Database storage - Load data on startup, queue DB changes to be done async and at intervals (instead of as they happen, that'd kill performance), and empty queue on shutdown.
  • Highly configurable - Almost everything will have some degree of configuration to suit your server's needs.
  • Efficient - Despite major mechanics changes and an extensive event listening setup, GlobalWarming is fast.

Negative Climate Damages (Sample Model)

Higher temps inherit the damages from the lower temps

| Global Temp | Effect 1 | Effect 2 | Effect 3 | Effect 4 | | ------ | ------------ | ------- | --------|-----------| | 14.0 C | None | | | | | 15.0 C | Some mobs spawn less | some mobs spawn more | | | | 16.0 C | +1 Sea level rise | Some fish die | Ice/Snow stops forming | | | 17.0 C | +1 Sea level rise | Flora species growth stunted | Aquatic life stops spawning | Ocean flora/fauna die | | 18.0 C | +1 Sea level rise | Area Potion Effect Clouds | Farm yields lower | Snow/Ice melts | | 19.0 C | +1 Sea level rise | Forest Fires | Slower Health Regen | Frequent T-Storms | | | 20.0 C | +1 Sea level rise | Severe Forest Fires | Violent T-Storms | Permanent Slowness Effect |

These are just a sample of the possible effects, these will be configurable and implement randomness and probabilities.

Ecological Niche

Niche - Species have a temperature range in which they can survive - Plants also have niches (Sunlight, Temperature, Water, Nutrients, CO2, Soil, etc)
