Game Development with AI
Finding and Fixing Game Bugs with Gemini
Investigate game bugs with Gemini and Gemini CLI. Use reproduction steps, a focused code change and repeat checks in a practical pause-and-resume example.

Provide expected behaviour as well as the error
Gemini is a model family. Gemini CLI can work with file and command tools; it does not replace a game engine. Include the engine version, reproduction steps and expected result alongside the error message.
Investigate duplicate input after resuming
Example brief: After pause and resume, one tap sometimes triggers twice. Inspect where input listeners attach and propose a reproduction plan first. Make the smallest justified fix, then retry pause and scene transitions. Do not redesign the levels.
This is a learning scenario, not a report of that bug in the pictured game. When sharing logs, retain necessary error context while removing player data.

How to check the result
- Can the issue be observed using the same steps before the change?
- Were pause, restart and returning from the background tried again?
- Does the change address only the relevant cause?
An open engine does not prove a completed test
A successful command does not verify every scene interaction. Try the changed flow on a real phone. Record checks that could not run and repeat the same scenario to assess whether the problem returns.

Frequently asked questions
Does using Gemini require players to be online?
Using a development tool is different from adding model calls to the game. The game’s actual features determine connectivity requirements.
