PlayerPrefs Editor

Lists, edits, deletes, and exports Unity PlayerPrefs (int / float / string).

Editor-only. Unity 2021.3+. Lives in Rivet.Editor (includePlatforms: Editor). No extra packages.

Editor window

ArTchie / Rivet / PlayerPrefs Editor

Control	What it does
Refresh	Rebuilds the table from known keys (Windows registry + keys you loaded/added this session).
Export JSON	Writes <project>/RivetReports/player-prefs.json (creates the folder if needed).
Manual key / Load	Look up any key by name, even if it was not discovered automatically.
Add	Create or overwrite a key (int / float / string).
Table Set / Delete	Write the edited type/value, or PlayerPrefs.DeleteKey.

Types are int, float, and string only. PlayerPrefs.Save() is called after every successful write or delete.

Batchmode (CI)

Unity -batchmode -nographics -quit -projectPath <proj> -executeMethod Rivet.PlayerPrefsEditor.RunBatch -rivet-out <file.json>

Batch is export-only unless you pass a mutate set:

… -rivet-set-key volume -rivet-set-type float -rivet-set-value 0.75
… -rivet-delete-key volume

Arg	Meaning
-rivet-out <file.json>	Output path. Default: <project>/RivetReports/player-prefs.json
-rivet-fail	Accepted for kit consistency. Mutation errors already exit 1. Export-only exits 0.
-rivet-set-key + -rivet-set-type + -rivet-set-value	Write one key, then export. Type is int, float, or string.
-rivet-delete-key	Delete one key, then export. Fails if HasKey is false.

Do not mix delete and set flags. Also accepts -rivet-out=file.json and -rivet-set-value=-1 (equals form is required for values that start with -).

RunBatch only calls EditorApplication.Exit when Application.isBatchMode is true. It logs count=, whether a mutation ran, and the output path.

JSON

{
  "tool": "PlayerPrefsEditor",
  "generatedUtc": "2026-08-18T02:00:00Z",
  "productName": "MyGame",
  "companyName": "MyStudio",
  "count": 2,
  "items": [
    { "key": "score", "type": "int", "value": 12 },
    { "key": "volume", "type": "float", "value": 0.75 }
  ]
}

value is a JSON number for int/float and a JSON string for string. productName / companyName come from PlayerSettings.

Notes

• Windows Editor only: known keys are read from the Unity PlayerPrefs registry locations for this project's company/product:
  • HKCU\Software\Unity\UnityEditor\<company>\<product>
  • HKCU\Software\<company>\<product>
• Only value names that match Unity's key_h<hash> pattern and pass PlayerPrefs.HasKey are listed. Subkeys are never enumerated. Unrelated registry trees are never opened.
• Company/product names that contain \ or / skip the registry read entirely.
• macOS / Linux Editor: no automatic listing. Use Manual key or Add. Batch export may be an empty items array.
• DWORD registry values are treated as int (Unity also stores floats as DWORD; switch the type popup if needed).
• Empty projects and a missing RivetReports folder are fine.
• Does not dump EditorPrefs. Does not walk HKLM or sibling HKCU keys.
