Cannonballs are 弹药 used by the 大炮. While held by the player or selected in the hotbar, using ⚒ 使用/攻击 on a cannon will fire one shot from the cannon's current angle. Cannonballs can also be fired from in the inventory by clicking on the cannon while holding the Auto Select key. On contact with a solid block, a Cannonball will explode, dealing damage in a small radius but leaving placed blocks intact.
Cannonballs are puchased from the 海盗 for 15 .
