ForceNether

Unstoppable Nether Portal Creation - No Mod Can Stop It!

🔥 What is ForceNether?

ForceNether is a server-side only mod that forces Nether portal creation to work, even when other mods try to disable it. Using powerful Mixin technology, it bypasses all restrictions and ensures portals can always be created when you have a valid obsidian frame.

✨ Key Features

✅ Force-Enable Portal Creation - Portals WILL be created if the frame is valid
✅ Bypass All Restrictions - Works even when other mods cancel portal events
✅ Server-Side Only - No client installation required
✅ Dimension Agnostic - Works in any dimension (Overworld, Nether, End, custom)
✅ Event Bypass - Injects before Forge events fire, making it impossible to cancel
✅ No Configuration - Just install and it works
✅ Status Command - Check if mod is working with /forcenether status

🎯 Why Use ForceNether?

Problem

Some modpacks or server plugins disable Nether portals for various reasons:

Dimension restrictions
Custom progression systems
Server performance rules
Compatibility issues

Solution

ForceNether overrides these restrictions at the core level, ensuring portals always work when players have built a valid frame.

🔧 How It Works

ForceNether uses Mixin injection to intercept the flint and steel usage at the deepest level:

Player uses flint & steel on obsidian
↓
FlintAndSteelItem.useOn() called
↓
FORCENETHER MIXIN RUNS HERE ← Before everything else!
↓
Valid portal frame found?
  ├─ YES → Create portal → Success (vanilla code never runs)
  └─ NO → Continue to vanilla code

Technical Details:

Injects at @At("HEAD") - executes FIRST
cancellable = true - can stop vanilla logic
Direct call to PortalShape.createPortalBlocks()
Forge events never fire = other mods can't interfere
