How do I start with Create Big Cannons?
Start by crafting a Cannon Crafting Wand and a Cannon Welder, then gather bronze or cast iron ingots to weld together a barrel, chamber, and breech. Attach the assembled cannon to a Cannon Carriage and load a Powder Charge plus a projectile before firing.
How do I use Create Big Cannons Mod?
Build a cannon from welded parts, mount it on a carriage, then load propellant and a round through the breech. Aim with the aiming controls and fire; for sustained fire, feed rounds automatically with an Autocannon Ammo Container and Autoloader.
How do I make an autocannon in Create Big Cannons?
Weld an Autocannon Barrel, Breech, and Recoil Spring together, then attach an Autocannon Breech Extractor and feed it with Filled Autocannon Cartridges. Use an Autocannon Ammo Container and Autoloader to keep it firing continuously.
What ammo types are in Create Big Cannons?
Common rounds include AP Shot, AP Shell, HE Shell, Flak, Shrapnel, Smoke, and Mortar shells, plus Autocannon rounds like AP and Flak. Each behaves differently — AP punches through armor, HE explodes, Flak bursts in air, and Shrapnel sprays fragments.
How do I load a cannon in Create Big Cannons?
Open the breech, insert a Powder Charge or Filled Cartridge, then insert the projectile behind it, and close the breech. Quick-Firing and Sliding Breeches let you reload faster than a basic breech.
How do I cast cannon parts in Create Big Cannons?
Use Cast Moulds like the Autocannon Barrel, Breech, and Recoil Spring moulds placed in a Basin Foundry setup, then pour molten metal from a foundry into them. Once cooled, the cast part can be welded into a finished cannon component.
Why wont my cannon fire in Create Big Cannons?
The most common causes are an open breech, no propellant loaded, or no projectile in the chamber. Make sure the breech is closed and both a Powder Charge and a round are seated before firing.
How do I make an autoloader for Create Big Cannons?
Build a mechanical arm or funnel system that pulls Filled Cartridges from an Autocannon Ammo Container and inserts them into the breech each cycle. Time the arm's rotation with the cannon's firing cycle so it loads between shots.
Does Create Big Cannons work on Bedrock?
No — Create Big Cannons is a Java Edition mod built on Create, and Create itself is not available on Bedrock. Bedrock players cannot install or run this mod.
Does Create Big Cannons cause lag or performance issues?
Large cannon arrays, many simultaneous projectiles, and complex autoloader contraptions can hurt performance, especially on servers. Limit the number of actively firing cannons and simplify autoloader mechanisms to reduce tick load.
