🧠 ChunkSense

Smart chunk loading + memory watchdog for Minecraft Forge 1.20.1

ChunkSense does two things that no other mod does:

1. Smart Chunk Prioritizer — chunks are loaded not in a circle, but along the vector of view and movement. Looking north — northern chunks load first. Running east — chunks ahead pre-load.

2. Memory Watchdog — monitors RAM in real time. If there's not enough memory, it automatically unloads distant chunks, reduces render distance, and clears the cache. The HUD overlay shows real-time status.

⚡ Features

  • 🎯 View-direction priority — Chunks in camera direction load first
  • 🏃 Movement prediction — Pre-loads chunks along player velocity vector
  • 📊 RAM monitoring — Tracks memory usage every second
  • 🚨 Auto-unload — Unloads far chunks when memory is low
  • 🔭 Dynamic render distance — Auto-adjusts render distance based on RAM
  • 📟 HUD overlay — Shows RAM %, FPS, render distance on screen
  • ⚙️ Fully configurable — All thresholds and features toggleable
