How to Fix Hit Registration Problems in Multiplayer

Bad hit registration online is latency between what the shooter saw and where the server thinks targets are. Lag compensation fixes it. Here is how.

How to fix it

1. Rewind on the server

When a client reports a shot, the server rewinds the targets to their positions at the time the client fired (accounting for the client's latency), then tests the hit against that historical state.

2. Validate against the rewound state

Confirm the hit using the rewound positions so a shot that connected on the shooter's screen counts, even though the target has since moved. This is what makes hits feel fair on both ends.

3. Keep authority on the server

The server still decides hits to prevent cheating; lag compensation just makes its decision match what the shooter saw. Never trust the client's hit claim outright, but account for what it legitimately saw.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
