Quick answer: Apply hazard damage on a defined interval while the target is inside, with clear enter and exit handling, so it neither spams nor under-applies.
Hazards damaging incorrectly is interval and trigger handling. Here is how to fix it.
How to fix it
1. Damage on an interval while inside
Apply hazard damage on a defined tick interval while the target remains in the hazard, not once on enter (which under-damages) or every frame (which kills instantly). The interval controls the damage rate.
2. Handle enter and exit
Track when a target enters and exits the hazard so damage starts and stops cleanly. Missing exit handling can keep damaging after the target leaves; missing enter handling can fail to start damage.
3. Define the damage clearly
Decide the damage per tick and interval so the hazard is dangerous but fair, and apply it consistently. Vague or frame-dependent hazard damage feels random — too deadly or harmless depending on frame rate.
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.
Ship the fix, watch the signature disappear from the next build. That's how you know it's really gone.
