Project overview

CBC Navigators Fire control computers for Create: Big Cannons . Instead of eyeballing elevation and traverse by hand, punch in a target's coordinates and let a navigator block calculate and set the cannon's aim for you — gated by mechanical calculation time, range, and (on the punch-card tiers) resource consumption, so it's a real machine to build and power, not an instant win button. This is an unofficial, third-party addon for Create: Big Cannons, not affiliated with or endorsed by its authors. CBC Navigators adds a family of kinetic-powered "computer" blocks that link to a cannon mount and aim it for you. Punch in X/Y/Z target coordinates, give the block some rotational speed to power its calculation, and once it finishes it writes the correct yaw and pitch straight onto the mount. No more manual trig. There are three tiers, each a genuine trade-off rather than a straight upgrade path: Tier 1 — Mechanical Table Computer. Cheap, simple, crafted at a vanilla crafting table. Opens its own GUI, no consumables needed. Big range, but a coarse, "line of sight" solve with heavy random spread and no elevation compensation — a rough battery gun, not a sniper. Tier 2 — Pneumatic Navigator. Built on Create's mechanical crafting table. Uses disposable Punch Cards : punch a target, powder charge count, barrel length, propellant, and projectile onto a card at a loading station, then feed the card into the navigator. Runs a real parabolic ballistics simulation (gravity + drag) and compensates for height, with much tighter accuracy — at the cost of a consumed card per shot and manual charge selection. Tier 3 — Kinetic Fire Control. The top tier. Links to a free-rotating Cannon Mount instead of a Fixed one, so it isn't limited to a ±45° traverse arc. Sets full-precision floating-point aim (no whole-degree rounding), has zero spread, and doesn't just solve the angle — it searches every configured projectile × every powder charge count and recommends the cheapest combination that actually lands the shot. All three still have to be built : placed facing the right kind of mount, wired into a rotational power source, and (for tiers 2/3) fed the right ammunition data. The calculation itself takes real time that scales with RPM, so a bigger gearbox is a legitimate way to make your fire control faster, not just a decoration. Every balance number (range, spread, calc speed, drag/gravity constants, max powder charges, per-projectile drag multipliers) is exposed in the server config, so pack/server admins can retune the whole mod without touching code. Requires: NeoForge, Minecraft 1.21.1, Create 6.0.7–6.1.0, and Create: Big Cannons 5.11.0+. How it all works The shared idea Every navigator is a small KineticBlockEntity : it needs an incoming rotation (a shaft, same as any Create machine) to actually run its calculation. No power, no result — it just sits at "Awaiting target" forever. More RPM = faster calculation, down to a small floor so it can't be trivially instant even with an absurd gear ratio. Once it has a target and enough power, it counts up "calculation ticks" over real time and then, when done, computes a yaw/pitch and pushes it onto whichever cannon mount it's linked to. Linking to a mount Tiers 1 and 2 link to a Fixed Cannon Mount . Place the navigator directly against the mount's face — the block automatically faces whatever you clicked when placed. The Fixed Mount's own trim range is hard-capped to ±45° around its placement facing (that's Create: Big Cannons' own limit), which is what keeps these two tiers feeling like defensive battery guns rather than free turrets. Tier 3 links to a Cannon Mount (the free-rotating one), the same way — place it facing the mount block. This one isn't limited to ±45°; it can traverse and elevate through the mount's full real range, whatever that cannon was built with. If the navigator isn't facing a valid mount, or the mount hasn't been assembled yet (Cannon Mounts need a redstone signal on their assembly input before Create: Big Cannons builds the actual contraption), the navigator will just report that status and refuse to solve. Tier 1 — Mechanical Table Computer Craft: vanilla crafting table, andesite alloy + redstone + compass. Use: right-click it to open a coordinate GUI (X/Y/Z), type a target, hit Calculate. The window stays open and shows live status. Behavior: big default range (400 blocks), but a large random lateral spread (10–25 blocks at the target's distance, config-tunable) and — by default — no compensation for the target being above or below the mount. It's a "point it roughly that way and pray" solver, appropriate for a starter battery. No consumables. Nothing to feed it besides rotation and a target. Tier 2 — Pneumatic Navigator Craft: Create's mechanical crafting table, brass sheets + electron tubes + precision mechanism. The Punch Card is the whole interface. Craft a card (paper + brass sheet, also on the mechanical crafting table), then away from the cannon: Right-click a block with the card → punches that block's coordinates as the target. Right-click empty air → cycles the barrel length (0–your configured max cannon length) stored on the card. Shift + right-

FreeMinecraftMods decision guide

This mod is most relevant to players looking for Create, Addons on NeoForge. Treat those labels as discovery hints, then verify the exact file and dependency list on the official project page.

The source record was updated on Jul 27, 2026, which is a recent freshness signal. A recent date does not guarantee support for every loader or Minecraft version, so still inspect the current file list.

What to verify before choosing a file

• Confirm that the file is published by the credited creator on the linked official source.
• Match the Minecraft version exactly instead of relying only on a broad category label.
• Read dependencies, incompatibilities, and changelog notes before updating an existing instance.
• Match the loader or server platform and its required version. Forge and NeoForge are not interchangeable.
• Back up worlds and configuration files before testing the project in a long-term save or public server.
