Information
Basic Info
The CDT (Compact Double-Cannon Turret) is a twin TNT Cannon with an adjustable arc functional in Vanilla Minecraft. It has two TNT cannons in the shell in order to increase the damage radius on the target. The shell of the turret and gun barrels are for both aesthetic purposes in order to cover up unsightly exposed Redstone and for protection if the turret is shot at by another TNT cannon. It's envisioned as an intermediate weapon between the DST and CSTs of Lanier's Mark 3 combat ships. Cruiser armament with a significant punch. This also serves as a pretty cheap cannon for use on your ships or to place on your bases as defenses. Essentially, it's a more compact version of the DHT I posted a while back:

Nerd Stuff
The central timing mechanism for the gun is a pulse extender. How it works is that when the turret is powered by the Redstone torch tower underneath it, the propellant is dispensed. Upon powering the turret, the comparator clock is also locked preventing it from dispensing projectiles too early while a delayed signal is sent to the back of it. When the power turns off, the comparator clock is unlocked and the delayed signal stays on for a period of time turning the comparator clock on dispensing projectiles. A separate repeater train is sent to the pistons which control the arc of the gun. The pulse extender acts to determine when the piston will extend and when it will drop. The projectiles when dispensed will sit on top of the extended piston and drop when the piston retracts.

The point at which the projectiles are at while they fall as the piston retracts when the propellant explodes is what determines the arc/trajectory of the gun. The longer the pulse is given to the gun, the later the piston will drop and thus the higher the trajectory. The shorter the pulse is given to the gun, the lower the trajectory. Because the projectiles are in mid-air when the propellant explodes, the blast force from the propellant TNT is unhindered by anything and allows the gun to reach much longer ranges with less propellant than most guns that use slabs or other mounting blocks for their projectiles.

The central timing mechanism/pulse extender is outside of the gun and can be wired to multiple turrets in order to adjust the trajectory and fire multiple turrets at the same time with the same trajectory.

Movecraft Compatibility
The turret is compatible with the Movecraft plugin and can be mounted on airships or as a stand-alone rotating turret if you wish to use it for base defense. This gun is primarily designed for more moderately sized combat vessels of Royal Navy/Lanier size standards such as their cruisers. The subcraft rotate sign in the gun allows you to rotate the turret when right-clicking it or left-clicking it if Movecraft is installed.

The color pallet of the design and functional basis was based on that of Royal Navy weapons made by BaccaYarro. Design inspirations linked here:

Stats

  • Max Range: 190-210m (190-210 Blocks)
  • Projectile: 12x TNT per turret
  • Propellant: 9x TNT per cannon (two cannons in each turret)


Plugin Requirements ( None / Optional )

No plugins are required for the cannon to function as it is a purely Redstone device. However, the cannon can be used on Movecraft warships with their turret feature to allow it to face in different directions. Some servers that run Movecraft are ToTheEnd, Airship Pirates, and Strangelands.

Terms of Use

You may use or modify this gun on your server, builds, and/or ships but be sure to leave a diamond, credit me, and link the gun if possible. Thank you!

Excellent enginering! I'm currently working on a launcher myself actually! Allthough it's a completely different design. It will be an adjustable artillery, meaning it will be able to fire in any direction you desire :)

Am having a hard time with adjusting the arch, what repeaters do you use to adjust it and at what tick? Your cannon is awesome by the way!

Thank you!

Also the repeater that should be adjusted is the one between the two gray wool blocks, not the one coming from the button on the floor. The button on the floor serves to add adjust the arc a little bit higher.

Basically if you press the button on an elevated block, it'll fire the normal trajectory based on the repeater settings. But if you have those same settings and then press the button on the floor, it'll add a little bit more height to your shot. This allows you to fine tune your aim better. Hope this helps!
