Questions and answers
Is Sky Auto Player free?
Yes. It is open source under GNU GPL v3.0 and the packaged v4 release is available from the official Sky Auto Player GitHub Releases page.
Will I get banned for using Sky Auto Player with Sky: Children of the Light?
Sky Auto Player runs as a separate application and sends input through the Windows SendInput API. It does not inspect game memory, inject code into the game process or modify game files. Those technical boundaries do not guarantee that automated playback is permitted. It may conflict with Sky’s Terms of Service, so use it responsibly and at your own risk.
What file formats does Sky Auto Player support?
The supported set is JSON, .skysheet and JSON-compatible TXT. These files contain the structured sheet data that Sky Auto Player reads. See the native song parser for the current implementation.
Which Windows versions does Sky Auto Player support?
The packaged application supports 64-bit Windows 10 and Windows 11. Windows 7 and Windows 8 are not supported.
Where can I download Sky Auto Player?
Download the canonical Tauri NSIS installer from the official Sky Auto Player GitHub Releases page.
Does Sky Auto Player work on Mac or Linux?
No. The current packaged application depends on Windows-specific APIs and does not provide a Mac or Linux build. The supported package is for 64-bit Windows 10 and Windows 11.
What is the difference between JSON, skysheet, and TXT sheet files?
JSON is the canonical structured form. A .skysheet file is a JSON-based sheet with that extension, while a TXT sheet is a plain-text file containing a JSON-compatible structure.
How does Sky Auto Player update itself?
The app checks the configured v4 channel and offers Update and Restart. The official Tauri
updater, mediated by the Rust-owned UpdateService, verifies the exact NSIS artifact through its
.exe.sig and runs the current-user installer. V4 has no bundled custom updater executable,
portable ZIP updater, or MANIFEST.json.sig contract. If an update cannot be staged, download
the canonical installer from the official Sky Auto Player GitHub Releases page.
Why are some notes dropped during playback?
If other players hear missing notes, first compare local playback and network conditions. Packet loss or latency can affect what reaches the game server. A different network route may help in some cases; some users try Cloudflare WARP, but no third-party network tool is guaranteed to solve the problem.
Can I tune Sky Auto Player for a weak PC?
Yes. Open the in-app Settings and Diagnostics panels to inspect runtime status and adjust playback parameters:
- Game FPS & Hold Timing: Align the selected Game FPS with your in-game frame rate cap (e.g., 30 or 60 FPS) and adjust the Hold Frame Model to ensure reliable note registration.
- Timing Margin & Tolerances: Fine-tune the timing margin and late-down tolerance to match system dispatch capabilities.
- Diagnostics Panel: Review real-time dispatch telemetry and focus status directly inside the application.
Can I build Sky Auto Player from source?
Yes. Clone the repository, install the pinned Rust
toolchain and Bun, then build the native Tauri workspace under desktop/. The repository’s
canonical checks and release tooling are Rust/Bun based; the packaged app does not require a developer toolchain.
Does Sky Auto Player need admin rights?
The canonical v4 app uses a current-user Tauri NSIS installer and does not require administrator
access for normal use. Uninstall it through Windows Installed apps. Updates use the official
Tauri updater through the Rust-owned UpdateService.
Where are Sky Auto Player’s logs and config stored?
Application settings, cache, library data, and calibration state live under the app-data boundary in
%LOCALAPPDATA%\io.github.pumni.skyautoplayer\. Application logs are written to the logs\ subdirectory.
They are strictly separated from the installer-owned application directory and are preserved across updates.
Is Sky Auto Player related to the Sky Music web editor?
They are separate projects by separate authors, but they form a useful workflow pair. specy/skyMusic is an editor for authoring and exporting sheets; Sky Auto Player is the Windows player.
