Information
Basic Info
The MNT (Mini Naval Turret) is a naval/waterless TNT Cannon with an adjustable arc functional in Vanilla Minecraft. It's considered to be a naval gun as the cannon doesn't have water in it until it is fired. The water is dispensed when the gun is fired and retracted after the firing cycle. You may ask "why is this even necessary?" or something similar. This is necessary as some Movecraft craft types cannot have water on them. Crafts such as Ships, or Boats are all water crafts that cannot merge with water and thus cannot have water in their TNT cannons. 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.

I built this gun as a kind of test a while ago to see how much propellant I could fit onto something based on the MST by BaccaYarro. The result was that it required numerous design changes and couldn't submerge. But despite being unable to submerge, it did make for a good naval gun for surface ships.

I had this cannon design sitting unlisted for a very long time for some reason but I feel like it's time to upload it :D.

DO NOT REMOVE THE WATER BUCKET

Please Leave A Diamond If You Enjoyed!

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.

A separate wire in this gun to the water dispenser makes this a naval gun. One of the dispensers in the propellant chamber has a water bucket that dispenses with the propellant. A separate repeater trail within the gun attached to the piston mechanism sends a signal to the water dispenser to retract the water after the gun has finished cycling.

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 Destroyers. 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.


Stats

    • Max Range: 390-410m (390-410 Blocks)
    • Projectile: 2x TNT per turret
    • Propellant: 12x TNT per 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!
