funman300 6037596cc0 fix(engine): double-click move animation no longer plays twice
A successful double-click was rendering the slide-to-destination
animation twice — once from the first press's MoveRequestEvent
landing, and again from the release's StateChangedEvent racing the
in-flight CardAnim and replacing it from the mid-animation
position.

The frame trace:

  Frame N (second press):
    handle_double_click → MoveRequestEvent (queued)
    start_drag           → DragState set, drag.committed = false
                            (start_drag never mutates Transform; the
                             card is still visually in place)
    handle_move          → applies the move, fires StateChangedEvent
    sync_cards_on_change → cur ≠ target, inserts CardAnim slide
                            (animation #1 starts)

  Frames N+1, N+2, …:
    follow_drag idles (drag uncommitted, cursor not moving)
    CardAnim animates the card from old to new pile

  Frame N+K (release):
    end_drag             → drag.committed = false branch:
                            drag.clear() + StateChangedEvent  ← CULPRIT
    sync_cards_on_change → sees the card mid-CardAnim
                            (cur ≠ target), replaces CardAnim
                            with a fresh one starting at the
                            current mid-position (animation #2
                            visibly restarts the slide)

The fix is one line: drop the StateChangedEvent write in the
uncommitted-drag branch of end_drag. The defensive resync was
never needed there — start_drag only mutates the DragState
resource on press, never card transforms, so an uncommitted drag
has no visual side effect to undo. The committed-drag branch (line
762) keeps its StateChangedEvent write since snap-back from a
real drag does need a resync.

Existing tests pass unchanged. The bug only manifested in the
specific timing of double-click → quick-release before
animation-complete; an integration test would require driving
mouse press/release across several frames with a dispatched
GameMutation pass between, which is heavier than the fix
warrants.

Solitaire Quest

A cross-platform Klondike Solitaire game written in Rust, with a card-theme system, full progression (XP / levels / achievements / daily challenges), and optional self-hosted sync so your stats follow you across machines.

Features

  • Klondike Solitaire — Draw One and Draw Three modes; foundations are unlocked (any Ace lands in any empty slot, the slot then claims that suit)
  • Card themes — bundled hayeah/playing-cards-assets default plus user-installable themes (drop a directory under the data dir or import a zip from Settings → Cosmetic)
  • Modern HUD — reserved top band keeps cards from crowding the score readout; the action bar auto-fades when the cursor leaves it so it can't compete with the play surface
  • Drag feel — every legal drop target is highlighted in green during drag; cards cast a soft drop shadow that lifts when picked up; the stock pile shows a remaining-count chip so you can see how close you are to a recycle
  • Keyboard navigation — Tab cycles focus through buttons, arrow keys move within picker rows, Enter activates; works across every modal and the HUD action bar
  • Progression — XP, levels, unlockable card backs and backgrounds
  • 19 Achievements — including secret ones
  • Daily Challenge — server-seeded so every player worldwide gets the same deal
  • Leaderboard — opt-in, powered by your own self-hosted server
  • Special Modes (unlocked at level 5): Zen, Time Attack, Challenge
  • Sync — pull/push stats across devices via a self-hosted server
  • Color-blind mode — blue tint on red-suit cards alongside the suit glyph

Building

Prerequisites

  • Rust stable toolchain (rustup install stable)
  • Linux: libasound2-dev libudev-dev libxkbcommon-dev
  • macOS: Xcode Command Line Tools
# Fast development build
cargo run -p solitaire_app --features bevy/dynamic_linking

# Release build
cargo build -p solitaire_app --release
./target/release/solitaire_app

Controls

Every action also has a visible UI button — keyboard shortcuts are optional accelerators.

Key Action
Left click / drag Move cards
Double click Auto-move card to its best legal destination
Right click Highlight legal moves for a card
Space / D Draw from stock
U Undo
H Hint (highlight a legal move)
N New game
Z Zen mode
G Forfeit (during pause)
Tab / Shift+Tab Cycle keyboard focus
Enter Activate focused button / auto-complete (when badge is lit)
Esc Pause / dismiss modal
F1 Help / controls
F11 Toggle fullscreen
S / A / P / O / L / M Stats / Achievements / Profile / Settings / Leaderboard / Menu

Card themes

The default theme ships embedded in the binary, so the game runs self-contained with no external assets. To install another theme, drop a directory containing a theme.ron manifest plus 53 SVG files (52 faces + 1 back) under the platform data dir's themes/ folder, or import a zip from Settings → Cosmetic. The picker chip lights up the moment a new theme is registered. Themes are SVG-based, so they rasterise cleanly at whatever resolution the window happens to be.

Sync Server (optional)

To sync stats across machines, run the self-hosted server. See README_SERVER.md for setup instructions.

Once the server is running, open Settings → Sync Backend, enter the server URL and your username, and register an account from within the game.

Running Tests

# All tests (982 passing as of v0.11.0)

Credits

Built on Bevy and the wider Rust ecosystem (Tokio, Axum, sqlx, Serde, kira, and many more). Card faces come from hayeah/playing-cards-assets (MIT, derived from the public-domain vector-playing-cards library); the default card back is original work; the UI font is FiraMono-Medium (OFL). All audio is synthesized programmatically by this project. See CREDITS.md for the full list and license details.
