How to Auto-Increment Build Numbers in Your Pipeline

If two builds share a version, a crash report cannot tell you which one broke. Automatic, monotonic build numbers fix that. Here is how.

How to fix it

1. Derive from CI

Use the CI run number or git rev-list --count as a monotonically increasing build number so it never collides.

2. Stamp it into the build

Write the number and commit SHA into the player settings or a generated constants file before building so it travels with the artifact.

3. Surface it in reports

Include the build number in crash and analytics payloads so every report ties back to an exact build.

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.
