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.
