Step-by-Step Build Guide

  1. 1Build a channel: 1 wide, 1 deep, 4-8 blocks long.
  2. 2Place water at the back of the channel (protects the cannon from charge explosions).
  3. 3Place dispensers along the sides of the channel, loaded with TNT (these are charges).
  4. 4At the front of the channel, place one dispenser facing up or forward (this is the projectile).
  5. 5Wire the charge dispensers to fire first (all simultaneously).
  6. 6Wire the projectile dispenser to fire 2-4 ticks AFTER the charges (use repeater delays).
  7. 7The charges explode in water (no damage), launching the projectile TNT forward.
  8. 8Press the button to fire. Adjust delays and charge count for range.
