Overview

TripwireDuper is a Minecraft Forge mod that introduces a redstone-triggered tripwire hook duplication system.

It enables controlled, redstone-based item duplication through strict structural validation.

---

Core Structure & Validation

Required Components:

• Tripwire Hook – Primary control block
• Tripwire Connection – Two blocks forward and one block lower
• North–South Alignment – Mandatory

All blocks are validated before activation.

If validation fails, duplication will not occur.

---

State Machine

IDLE → ARMED → TRIGGERED

IDLE – Structure missing or invalid
ARMED – Structure validated, waiting for redstone
TRIGGERED – Redstone transition (OFF → ON) executes duplication

---

Redstone System

• Block Placement Events – Structure validation
• Neighbor Update Events – Detect OFF → ON transitions

Only edge transitions trigger duplication. Constant power does nothing.

---

Safety & Control

5-Tick Cooldown Per Structure
Continuous Structural Validation
Air-Space Position Checking
Edge-Triggered Redstone Detection
Strict North–South Enforcement

---
