Create Big Cannons: controller

# Create Big Cannons Controller

**An unofficial addon for CBC Scope by Elice** (linked under Relations).
Not affiliated with or endorsed by CBC Scope, Create Big Cannons or Create.

CBC Scope lets you aim cannons through a scope. This addon makes that aiming **smooth and precise**, shows you **where your round will actually land**, and adds the **CRT Gunnery Station** so you can run a whole battery of cannons from one control room.

## CRT Gunnery Station
A screen the size of an item frame, with a brass bezel and a glowing green phosphor display.
- **Link a Scope Connector to a cannon** (right-click the cannon with it), then **right-click the screen with it** to load it. The connector is only a link now: scopes open from CRT screens, not from your hand.
- **Right-click the screen** with an empty hand to look through that cannon and control it; **right-click again** to leave. **Left click fires.** While you're scoped your character stays put (no walking or breaking blocks). **Sneak + right-click** takes the connector back out.
- The screen shows the cannon's name (rename the connector in an anvil), **bearing, elevation, cannon type, loaded round, ammo and distance**, with scanlines and flicker. It shows `NO SIGNAL` while the cannon is disassembled or out of reach, `OUT OF RANGE` past the configured range, and `> MANNED` when a player is seated on the cannon.
- One screen per cannon, as many as you like, each link independent. Several screens can watch the same cannon.
- **Works on Sable airships**, including while moving.

**Recipe** (shapeless): Brass Casing + Electron Tube + Glass Pane + Redstone. In CBC Scope's creative tab and Functional Blocks.

## Landing marker
A cross in the scope, replacing CBC Scope's barrel marker, shows where the loaded round will hit, drop included, with its distance and round type. **Green** = it will hit something, **red** = it won't.
- **Autocannons:** exact from the start. Reads barrel material and length, the round in the breech or magazine, and High-Velocity Cartridges. Uses **CBC Going Ballistic**'s own physics when it's installed.
- **Big cannons, Modern Warfare medium and rotary cannons:** learned from the cannon's **first shot** (the screen says `RANGING: FIRE 1` until then), then kept for that mount, even across reassembly.
- Accounts for **airship motion** (rounds inherit the ship's velocity) and stays put when zoomed or moving.
- Rocket launchers keep CBC Scope's own marker (guided rockets can't be predicted).

## Smooth, steady aim
- **Fixes the barrel shake:** the cannon settles and stays exactly on target.
- **Fixes the jerky barrel:** the angle reaches your screen every tick it moves. A still cannon sends nothing.
- **Correct scope camera on airships** (Sable): no jitter against the ship.

## Cannons, mounts and gunners
- Works with **CBC big cannons, autocannons and Modern Warfare cannons**, on **cannon mounts, fixed mounts, upside-down mounts and carriages**.
- **Cosmetic telescopic sight** on every linked cannon, sized to its barrel (hangs underneath on upside-down mounts). Hidden when the cannon already has a Modern Warfare sight.
- **Disassemble and reassemble** a cannon on the same mount and its screens re-link by themselves.
- **A player seated on a cannon keeps control**; linked screens become view-only.

## Cutting links
Someone linked a connector to your cannon? **Sneak + right-click the cannon's barrel with an empty hand.** Every connector and screen linked to it stops working at once, wherever it is (screens show `LINK CUT`). Re-link your own connector afterwards.

## Config
Mods list -> Create Big Cannons Controller -> **Config** (or `config/cbc_controller-common.toml`): CRT reach, max cannon range, link cutting, seated-gunner control, auto re-link, landing marker, learning from shots, cannon sight and its render distance.

## Requirements
