Highest Point Mod

Overview

This mod adds a challenging rule to your Minecraft gameplay: you must always be the highest point within your surroundings. If any block exists above your Y level within the detection radius, you will be penalized.

This mod is designed for a YouTube challenge where the player must always remain the tallest block in their vicinity while playing Minecraft.

Features

Core Mechanics

  • Overworld: If a block is above you, you die instantly (similar to /kill)
  • Nether: If a block is above you, you take rapid continuous damage (1 heart per tick) until the block is removed or you move away
  • End: Same as Nether, but damage only applies when you are standing on ground (not when bridging or pillar climbing)

Special Exceptions

  • Obsidian: Always ignored by the rule, allowing Nether portals to exist above you
  • Bedrock (End only): Ignored in the End dimension, but not in other dimensions

Configuration

  • Detection radius is configurable (default: 16 blocks)
  • Config file location: config/sky_limit.json
  • Edit the detectionRadius value to adjust the range

How to Use

  1. Install the mod alongside Fabric Loader
  2. Start your Minecraft world
  3. The mod will automatically check every few ticks
  4. Stay above all blocks within the detection radius to survive!

Detection Radius

By default, the mod checks within 16 blocks horizontally from your position. To change this:

  1. Open config/sky_limit.json in your Minecraft directory
  2. Change the detectionRadius value (recommended: 8-32)
  3. Restart your world

Tips & Tricks

  • Build upwards rather than sideways when exploring
  • In the End, you can safely bridge or climb in the air without taking damage (as long as you're not standing on a block with something above you)
  • Use obsidian to create structures above you without triggering the rule
  • When fighting the Ender Dragon, make sure you're always the highest point on the main island

Known Limitations

  • Very large detection radii may cause slight lag (keep under 32 for best performance)
  • The check runs every 3 ticks, so there may be a tiny delay between a block appearing and the penalty triggering
  • This mod is for the server-side and works in both singleplayer and multiplayer
