The Cannon firing a Cannonball.

The Cannon is a Hardmode placeable furniture/weapon, purchased from the Pirate for 25 GC. Once placed, it can be fired by pressing Use / Attack key on it with a Cannonball in hand, by pressing the Auto Select key with a Cannonball in the player's inventory, Mobile version or tapping the Cannon with a Cannonball in hand. In either case, the Cannonball is consumed, and the Cannon fires an arcing Cannonball that does not destroy blocks and explodes upon contact with a solid block or after piercing three enemies.

The angle of a placed Cannon can be adjusted by pressing Open / Activate key on either side of the Cannon to rotate it in that direction, Mobile version or tapping the side of the Cannon. There are 9 possible orientations and it cannot fire downward, though the arcing trajectory of the Cannonballs can be used to hit targets below the emplacement. Each rotation tilts the Cannon by one step (22.5°).

(Desktop, Console and Mobile versions) The Cannon can also be triggered by wire. Depending on where the wire is connected, it will either shoot a Cannonball (with a cooldown of 0.5 seconds[1]) or rotate toward the side the wire is on. Cannonballs fired in this way are mostly aesthetic, dealing no damage or knockback, but will still trigger a Teal Pressure Pad if it hits one.

Notes

  • Although it appears to only take up a 3×2 space, it actually requires a 4×3-tile empty space; this is because the Cannon needs the extra space in order to properly rotate.
  • If used quickly, the sound that the Cannonballs make exploding on the ground causes the sound of the Cannon launching the Cannonballs to stop before it is completed, making shorter bursts of incomplete noise.

Tips

  • The Cannon is powerful but immobile, functioning as a fixed gun emplacement, and so is best suited for tasks such as home defense.
  • Despite being weaker than the Bunny Cannon, the Cannon could be seen as a better choice of home defense, due to the fact Cannonballs are easier to obtain than Explosive Bunnies.
  • When fired on a flat surface:
    • At 0° the Cannonball impacts the ground 21 tiles away.
    • At 22.5° the Cannonball reaches a maximum height of 8 tiles and impacts the ground 43 tiles away.
    • At 45° the Cannonball reaches a maximum height of 23 tiles and impacts the ground 45 tiles away.
    • At 67.5° the Cannonball reaches a maximum height of 32 tiles and impacts the ground 29 tiles away.

Trivia

  • The Bunny Cannon can be considered a more powerful version of the Cannon.
