Bug Tracking for Naval Combat Games

Naval combat puts ships on a simulated ocean, models how they take damage and flood and sink, and usually pits players against each other over the network. Bugs concentrate in those three systems: a ship that handles wrong on certain waves, a damage model that sinks a vessel incorrectly or refuses to, a desync where two players see different ships in different places. Each depends on a specific simulation or network state, so this post is about capturing the sea state, the ship physics, the damage context, and the network conditions so the combat bugs that define naval games become reproducible rather than lost at sea.

Water and ship physics

The ocean is a live physics simulation, and a ship's handling depends on the water under it: the wave height, the sea state, the ship's speed and heading relative to the swell. Many naval handling bugs only appear in specific conditions, a ship that capsizes turning across a big wave, that planes oddly at high speed, that behaves wrong in a particular sea state. Capture the water simulation state at the moment of failure, the wave parameters, the sea state, and the ship's physics state, its velocity, heading, and orientation, so a handling bug is tied to the conditions that produced it.

Because the ocean is always moving, the exact wave configuration at the moment of a bug is gone an instant later, which is why capturing it matters so much. A report that says the ship flipped is useless if you cannot recreate the wave it flipped on, but a report carrying the sea state and the ship's heading and speed lets you reproduce the conditions and watch it flip again. Naval handling bugs live in the interaction between the ship's dynamics and the water's state, so both halves have to be in the report or the bug stays unreproducible.

Damage, buoyancy, and sinking

The damage model in a naval game is unusually physical: hits cause flooding, flooding shifts weight and buoyancy, and enough flooding sinks the ship. Bugs here are about that chain, a ship that takes flooding damage but never sinks, that sinks instantly from a minor hit, that floats while visibly destroyed, that lists wrong as compartments flood. Capture the damage and buoyancy context: which compartments are flooded, the hull integrity, the current buoyancy and trim, and the hit that triggered the report, so the sinking math is reproducible.

This system is also where balance and exploits live, because players probe for ways to make ships unsinkable or to one-shot opponents. A compartment that never floods, a hit location that does disproportionate damage, a buoyancy calculation that can be gamed. Capture the hit, the damage applied, the resulting flooding, and the buoyancy response so you can tell a balance bug from a physics bug. In a genre where sinking the enemy is the entire objective, a damage-model bug that breaks how ships sink breaks the core of the game and needs to be reproducible fast.

Netcode and multiplayer battles

Naval combat is usually multiplayer, and ship physics over the network is hard because every client must agree on where heavy, momentum-driven vessels are despite latency. Desyncs are the signature netcode bug: two players see a ship in different positions, a hit that lands on one client misses on another, a ship that sinks for one player and sails on for the other. Capture the network context, the player's role as host or client, the session, latency, and recent desync indicators, so a battle bug that only appears in multiplayer is recognizable as a replication problem.

Authority decides most of these, because ship position and damage are computed somewhere and replicated, and a client that disagrees with the authority has a prediction or reconciliation bug. Naval physics makes this worse than in faster games, since a ship's heavy momentum means a small desync compounds into a large positional gap before correction catches up. Capture whether the reporting player held authority for the ship in question and what they saw versus the server, so you investigate the right machine rather than chasing a local-looking bug that is really a network reconciliation failure.

Telling physics from netcode

The first triage question for a naval combat bug is whether it is physics or network, and the captured context answers it. A handling or sinking bug that reproduces in single player is a physics bug in your ocean or damage model; one that appears only in multiplayer and depends on who you ask is a netcode bug. Tagging each report with its system, water physics, damage model, or netcode, using the sea state, damage context, and network role you captured, routes it to the right owner and the right fix without a round of back-and-forth.

Some bugs span both, and the context keeps you honest. A ship that sinks for one player and not another could be a damage-model bug that only one client computed, or a pure replication bug, and only having the damage context and the network role in the same report lets you separate them. Capture both even when one seems obviously at fault, because the interaction between heavy ship physics and network reconciliation is where the nastiest naval combat bugs hide, and you want the full picture when a battle goes wrong for half the players in it.

Setting it up with Bugnet

Bugnet's in-game report button captures game state automatically, so a player reporting a naval bug hands you the sea state, ship physics, and damage context without describing it. Map the wave parameters, the ship's velocity and heading, the flooding and buoyancy state, and the network role to custom fields, and each report arrives ready to reproduce. Crash reports carry stack traces and platform context, so a physics crash in heavy seas arrives with the platform and the simulation state that triggered it, which is what these conditional bugs require.

Occurrence grouping folds duplicate reports into one counted issue, which matters because a sinking-model exploit or a common desync will be hit by many players in many battles independently, and the count tells you how widespread it is. Filter by the system custom field to separate physics bugs from netcode bugs, and sort by occurrence to find the one breaking the most battles. One dashboard lets a small team triage by what threatens combat first, so an unsinkable-ship exploit or a battle-ruining desync rises to the top on its own rather than hiding among handling complaints.

Keep the battles fair and reproducible

The teams that keep naval combat games fair are the ones whose reports carry the sea state, the ship physics, the damage context, and the network role by default, because in this genre those signals are what make a battle bug reproducible. Decide to capture them on every report from the start, and a desync or a sinking exploit becomes something you reproduce under the same conditions instead of an argument between players who saw different things. The simulation that makes naval combat exciting also makes its bugs traceable when you record its state.

Keep the captured context aligned with your physics and netcode as they evolve, because a new sea state, a new damage type, or a change to your replication model introduces new ways for ships to misbehave. Treat the sea-state, damage, and network capture as living instrumentation. In a genre where heavy physics meets competitive multiplayer, the studios that thrive are the ones who can go from a player's report of a ship that sank wrong to a verified fix quickly, and that speed comes from capturing the simulation and network state at the moment the battle broke.

Naval combat bugs live in water physics, the damage model, and netcode. Capture the sea state, the damage chain, and the network role and they stop being lost at sea.
