Quick answer: Define a knockdown state with a tuned duration, a clear get-up transition, and handling for being hit again while down.
Knockdown timing issues are an unclear down state. Here is how to fix them.
How to fix it
1. Tune the knockdown duration
Set how long the character stays down to feel right — long enough to matter, short enough not to frustrate. An instant pop-up makes knockdowns meaningless; too long feels like a loss of control.
2. Handle the get-up transition
Transition cleanly from down to get-up to neutral, with the character protected or vulnerable as intended during get-up. A missing or mistimed get-up leaves the character stuck on the ground or popping up unnaturally.
3. Handle being hit while down
Decide what happens if the character is hit again while knocked down — extended down time, an OTG hit, or invulnerability. Unhandled, repeated hits while down can lock the character in the knockdown state.
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.
