TNT extension
TNT extension adds explosive weapons that fire TNT, TNT minecarts and explosive arrows on the server, with hold-to-charge and underwater use.
What it does
Holding the use button charges a TNT blaster, and releasing it summons TNT at a rate of 20 per second. Explosion level 2 of 4 is available as a variant. A second right-click fires the charged blaster, and the weapon handles much like a bow that shoots explosive projectiles in volleys. The blaster keeps working underwater, and a ground hold lets the player move for longer while charging. Later updates added a super TNT option that summons 1000 TNT, a TNT laser and a fixed blaster texture.
The server is the only side that must run the mod, since Fabric API is required beside it on every loader. Clients may also install it, but players who join a server running TNT extension do not need it. Builds are published for Fabric, Forge, NeoForge and Quilt, plus a data pack, and cover the game versions 1.20.5 – 26.3. The code is under the Apache License 2.0, and the project is not open source. Version 1.5.1 for 26.3 is the latest file on every loader, dated 2026-09-18.
