PROFILE
Simon Wittber
Simon Wittber focused on enhancing the stability and reliability of the Unity-Technologies/InputSystem repository over a five-month period, addressing six critical bugs that impacted editor workflows and input handling. He improved composite binding accuracy after device resets, safeguarded against exceptions during action map edits, and ensured persistent UI states across sessions. Simon’s work involved deep debugging and editor scripting in C# and XML, leveraging Unity’s UI Toolkit and Input System. By introducing user prompts for unsaved changes and refining serialized property management, he reduced data loss risks and improved developer productivity, demonstrating a thorough, detail-oriented approach to complex system maintenance.

Mar 1, 2025March 2025: Implemented unsaved changes protection when loading a new Input Actions asset into an open Input System editor, introducing a user prompt that asks to Save, Discard, or Cancel to prevent accidental data loss. The change enhances editor reliability and asset workflow safety, with direct traceability to the ISXB-1343 ticket and the associated commit in the repository.

Jan 1, 2025Month: 2025-01 — Focused on stability and reliability improvements for Unity’s Input System. No new user-facing features were shipped. Delivered two critical bug fixes in Unity-Technologies/InputSystem that directly reduce crashes, preserve UI state, and improve editor reliability, enhancing developer productivity and workflow consistency. Key outcomes include preserving tree view state across saves and preventing playmode crashes when domain reload is disabled. These changes lower support burden and provide a more predictable development experience.

Oct 1, 2024October 2024 monthly summary for Unity-Technologies/InputSystem: Focused on stabilizing composite bindings and device-reset behavior to safeguard input fidelity in action handling. Addressed a regression in composite binding after a device reset by reverting a prior fix and ensuring correct evaluation of the composite key presses during an action handler, which fixes IsPressed accuracy. The fix was implemented in commit 43efc3b035f5211394ea2fe36c516be6ee2653b1 (ISXB-1127). This work reduces edge-case input bugs, improves reliability for developers relying on complex bindings, and enhances cross-device consistency during reset scenarios.
