Engine-neutral. Use when the user mentions save system, save/load,\n  game state persistence, save slots, autosave, save file corruption, or\n  migrating old saves to a new version.\n---\n\n# Save systems\n\nA save file is a **serialized snapshot of game state** that survives restarts.\nThe hard parts aren't writing bytes — they're choosing *what* to save, writing it\nso a crash mid-save can't corrupt it, and reading *old* saves after you ship a\npatch. Get those three right and the rest is plumbing.\n\n## When to use\n\n- Use to persist progress: player stats, inventory, world flags, settings,\n  positions — across sessions and game updates.\n- Use to design save slots, quicksave/autosave, and crash-safe writes.\n- Use when old save files break after a content/code change (versioning &\n  migration).\n\n**When *not* to use:** for Roblox cloud persistence specifics, use\n`roblox-datastores`. For the data model the save serializes (resources/SOs), use\n`godot-resources` / `unity-scriptableobjects`. For Godot's `FileAccess`/\n`ResourceSaver` and `user://` paths, defer to the Godot engine skill while\napplying the patterns here.\n\n## Core workflow\n\n1. **Decide what state is authoritative.** Save the *data* (hp, position, seed,\n   unlocked flags), not engine objects or scene nodes. You will reconstruct\n   objects from data on load — never serialize live node references.\n2. **Define a versioned schema.** Every save embeds a `version` integer. This is\n   the single most important field for a game you intend to patch.\n3. **Pick a format.** JSON/text for readability and debuggability; a binary\n   format for size/speed or mild tamper-resistance. Start with JSON.\n4. **Write atomically.** Serialize to a temp file, flush, then rename over the\n   real file. A crash leaves either the old save or the new one — never a\n   half-written one.\n5. **Load defensively.** Read version → migrate up to current → validate →\n   instantiate. Keep a backup of the last good save and fall back on parse error.\n6. **Autosave on safe boundaries** (level change, checkpoint), throttled, and to a\n   separate slot so it can't clobber a manual save.\n7. **Verify**: save, fully quit, relaunch, load — and confirm by inspection that\n   state matches. Test loading a save from the previous version.\n\n## Patterns\n\n### 1. Serialize state as plain data (not engine objects)\n\n```gdscript\n# Build a dictionary of pure data. Each savable object reports its own state.\nfunc capture_state() -> Dictionary:\n    return {\n        \"version\": SAVE_VERSION,                 # ALWAYS stamp the schema version\n        \"player\": { \"hp\": player.hp, \"pos\": [player.position.x, player.position.y] },\n        \"inventory\": player.inventory.to_array(),  # ids + counts, not Item nodes\n        \"flags\": world.flags,                    # e.g. {\"met_guard\": true}\n        \"seed\": world.seed,                      # regenerate procedural content\n    }\n\n# On load, RECONSTRUCT objects from the data — do not expect live references back.\nfunc apply_state(data: Dictionary) -> void:\n    player.hp = data[\"player\"][\"hp\"]\n    player.position = Vector2(data[\"player\"][\"pos\"][0], data[\"player\"][\"pos\"][1])\n    player.inventory.from_array(data[\"inventory\"])\n    world.flags = data[\"flags\"]\n```\n\n### 2. Atomic, crash-safe write (temp + rename)\n\n```gdscript\n# RIGHT: write to a temp file, then atomically rename over the target.\nfunc save_atomic(path: String, data: Dictionary) -> void:\n    var tmp := path + \".tmp\"\n    var f := FileAccess.open(tmp, FileAccess.WRITE)\n    f.store_string(JSON.stringify(data))\n    f.flush()                                    # ensure bytes hit disk\n    f.close()\n    DirAccess.rename_absolute(tmp, path)         # replaces the target; atomic on POSIX\n# WRONG: opening `path` directly and writing in place — a crash mid-write leaves a\n# truncated, unloadable save and destroys the player's progress.\n```\n\nRename-over-target is atomic on POSIX (same volume); on Windows a replace-by-rename\nisn't guaranteed atomic, so keep the previous file as `path + \".bak\"` before the\nrename — that backup is what actually guarantees you can recover from a bad write.\n\n### 3. Versioned load with migration\n\n```python\nSAVE_VERSION = 3\n\ndef load_save(raw_bytes):\n    data = parse(raw_bytes)                  # JSON/binary -> dict\n    v = data.get(\"version\", 0)\n    if v > SAVE_VERSION:\n        raise NewerSaveError(v)              # save is from a newer build; refuse\n    while v < SAVE_VERSION:                   # apply migrations in order, v -> v+1\n        data = MIGRATIONS[v](data)\n        v += 1\n        data[\"version\"] = v\n    validate(data)                            # check required keys / ranges\n    return data\n\n# Each migration is a pure function from one version's shape to the next.\ndef migrate_1_to_2(d):\n    d[\"flags\"] = {k: True for k in d.pop(\"completed_quests\", [])}  # list -> set-map\n    return d\nMIGRATIONS = {1: migrate_1_to_2, 2: migrate_2_to_3}\n```\n\n### 4. Save slots + throttled autosave\n\n```gdscript\nconst SLOT_PATH := \"user://save_%d.json\"      # manual slots 0..N\nconst AUTOSAVE_PATH := \"user://autosave.json\"  # separate file: never clobbers a slot\nvar _autosave_cooldown := 0.0\n\nfunc autosave_if_due(dt: float) -> void:\n    _autosave_cooldown -= dt\n    if _autosave_cooldown <= 0.0:\n        save_atomic(AUTOSAVE_PATH, capture_state())\n        _autosave_cooldown = 60.0             # throttle: at most once a minute\n# Trigger an immediate autosave on checkpoints/level transitions, not mid-combat.\n```\n\n## Pitfalls\n\n- **Serializing engine objects/node paths** ties saves to scene structure;\n  renaming a node breaks every old save. Save data, rebuild objects on load.\n- **No version field.** The day you ship a patch, every existing save is a\n  guessing game. Stamp `version` from version 1.\n- **In-place writes** corrupt saves on crash/power loss. Always temp-write then\n  rename; keep a `.bak`.\n- **Trusting the file blindly.** Saves get truncated, hand-edited, or\n  cloud-synced stale. Validate on load and fall back to backup on failure.\n- **Floats and locale.** Text serializers can drop precision or use comma\n  decimal separators in some locales. Use a locale-invariant serializer.\n- **Autosave clobbering manual saves**, or firing mid-action and saving an\n  inconsistent state. Use a dedicated autosave slot and save on safe boundaries.\n- **Storing secrets or trusting client saves in multiplayer.** A local save is\n  player-controlled; never treat it as authoritative for online state. For cloud,\n  handle the device's data limits and conflicts (`roblox-datastores`).\n\n## References\n\n- `references/versioning-and-migration.md` — schema evolution strategies, the\n  migration chain, backups/rollback, format trade-offs (JSON vs binary), and a\n  load-time validation checklist.\n\n## Related skills\n\n- `roblox-datastores` — cloud persistence, request limits, session locking.\n- `godot-resources`, `unity-scriptableobjects` — the data model you serialize.\n- `procedural-gen` — store the seed to regenerate worlds instead of saving them.\n- `rpg`, `survival-crafting`, `visual-novel` — genres that compose this skill.\n","tagline":"Design save/load for game state — choosing what to serialize, file formats, save slots, atomic crash-safe writes, schema versioning and migration, and autosave.
