About this Mod

TNT Duper

TNT Duper cover image

Allows dispensers to duplicate TNT without using up the TNT item.

What It Does

  • Power a dispenser that contains TNT and it will spawn a TNT that is lighted.
  • The TNT item used to trigger the dispenser remains in the dispenser, so you can keep using it without it running out.

Features

  • Infinite TNT dispensing from a single TNT item.
  • Works with any dispenser that holds TNT.
  • Compatible with vanilla TNT mechanics (same explosion behavior).
  • Works on both single‑player and multiplayer worlds.

Why Use This Mod?

  • Build automatic TNT farms without constantly refilling dispensers.
  • Simplify redstone contraptions that need repeated TNT bursts.
  • Save time and resources when testing explosions.
  • Easy to use – just place a dispenser and watch it duplicate TNT.

What You'll Notice

  • Dispensers can fire TNT without using up the TNT item.
  • The spawned TNT behaves like normal TNT and can be picked up or detonated.
