Advanced Firing Piece

This is the Core Block of Advanced Cannons. All other APS-parts connect to it, directly or indirectly.

Possible Connections
A Mantlet or Barrel (or any other variant of an APS-barrel) can connect to its front.

The gauge-snake can connect to the rear – Gauge Increasers, Gauge Cooling Units, and Gauge Increase Right Left Splitters.

Most things that can connect to the gauge-snake can also connect to any of the 5 non-front sides. Notably, Railgun Chargers cannot connect to it.

Ammo Input Feeders can also connect to those 5 sides, and will feed shells directly into the firing piece without need for Autoloaders – this is known as a "direct feed" cannon, and can be use to avoid the 8m shell-length cap, or to produce very compact cannons, possibly useful for light-AA purposes.

UI
Pressing Q while looking at the firing piece (or most connected components) will open the UI.

Controls
Left CTRL/Middle Mouse Button - Fires the weapon, when character is in a range of the weapon, or Fire Control Computer, or when controlled by AI using a Local Weapon Controller.

Limitations
Connecting to other firing pieces has no effect. If an Advanced Cannon component can connect to two different firing pieces, one will "steal" as many components as it can, so plan multi-gun Turrets accordingly.
