Quick answer: Lock horizontal movement to the ladder line while climbing and only release the climb when the player reaches the top exit, the bottom, or deliberately jumps off.

On a ladder the player should move up and down the rungs, not slide off the side into a fall. Constrain motion to the ladder. Here is how.

How to fix it

1. Constrain to the ladder axis

While in the climb state, ignore horizontal free movement and snap the player to the ladder's center line. Map vertical input to climbing up and down only.

2. Define explicit exits

Leave the climb state only on a clear condition: reaching the top ledge (snap onto it), reaching the bottom (return to walking), or a jump-off input that gives a deliberate push away from the ladder.

3. Keep the climb trigger sticky

Do not drop the climb just because the player's center briefly leaves the trigger volume. Use a slightly larger detach test so small jitters do not eject them into mid-air.

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.

The errors you never hear about are the ones quietly costing you players. Visibility turns them into a worklist.
