Quick answer: Disable Unbounded scrolling on the layout so Construct clamps the camera to the layout bounds, or implement a manual clamp accounting for the viewport size.

If your Construct 3 camera shows empty space at the level edges, unbounded scrolling is on. Disabling it clamps the camera. Here is how.

How to fix it

1. Disable Unbounded scrolling

In the Layout Properties, set Unbounded scrolling to No so the engine clamps the scroll position to the layout rectangle automatically.

2. Account for viewport size

Built-in clamping keeps the layout edge at the screen edge; if you need a margin, clamp scroll manually between half the viewport and layout size minus half the viewport.

3. Match camera bounds to level

Size the layout to your actual playable area, or use an invisible bounding solid, so the clamped camera never reveals unfinished background.

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 Construct 3 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.

Most of the time the fix is small. Seeing the failure clearly is the part that actually costs you.
