TNT Duper
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.
