Railgun

Template:Stub Template:Images needed The railgun is the first and, currently, the only available stationary weapon in Barotrauma. It is technically composed of three installations: the railgun proper, the railgun controller, and the railgun loader.

Function

The railgun uses railgun shells as ammunition. Those must be loaded by hand in the railgun loader; up to 6 shells can be loaded at a time. The usual railgun shells are hollow and can be filled with an item. This feature allows for the placement of explosives (for example a C-4 Block) inside, creating more damaging munitions if need be. Nuclear railgun shells are special ammunitions of extreme destructive power, which can be precious to bring down some creatures, such as Endworms or Coelanths. Due to the large radius of the ensuing explosion, it is however highly recommended to use this type of ammunition at a distance.

A railgun loader must be connected to one or more railguns proper in the submarine editor, it can not be connected outside of the editor. A railgun controller is connected to one or more railguns proper with wiring through their respective connection panels. Both the railgun controller and the railgun proper require power to function; however, the railgun loader does not require any power. A railgun proper requires a supercapacitor, which needs to be charged before firing, and each shot will use up some amount of this store to function as its power supply in order to be able to fire. Connecting the railgun proper directly to the power network will leave it unable to fire. Note that attempting to fire a railgun with no shell loaded doesn't empty the capacitor.

The railgun proper, when edited in the submarine editor, is given a pair of numbers under RotationLimits formatted thus: 0,180. These numbers are angles which describe the limits that the railgun proper can be rotated when aiming. A railgun proper with the RotationLimits set at 0,180 will be able to rotate from the right down and around to the left. A railgun proper with its RotationLimits set at 180,360, contrastingly, will be able to rotate from the left up and around to the right.

Usage

To use a railgun, the character must be positioned in front of a railgun controller and, when the railgun controller is highlghted, click 'e' on the keyboard. The railgun(s) proper can then be aimed while holding the right mouse button, and fired, using a shell loaded in the associated railgun loader(s), by clicking the left mouse button.

Damage Values

Item	Attack Damage	Bleeding Damage	Structure Damage	Damage Type	Stick to Entities?	Price	Source
Railgun Shell	100	10	200	Blunt	No	100 Marks	2 Steel Bars, Polycarbonate Bar
Nuclear Shell	1,000	10	200	Blunt	No	100 Marks	2 Steel Bars, Polycarbonate Bar, Uranium Bar

On top of inflicting damage upon direct hit, a nuclear shell also creates an explosion centred on the contact point.
