| # SNAPKITTY: Bifrost Runner — 2D game |
|
|
| **Play it live:** https://ahmadaliparr.github.io/snapkitty-2d/ |
|
|
| Built from your four art pieces: the hoodie kitten (player), the suited |
| Architect (NPC), the SNAP-OS dashboard (HUD language), and the |
| Snapkitty civilization poster (world backdrop). |
|
|
| ## Play it now — `index.html` |
|
|
| A playable 2D platformer prototype of the full game design. Open in any |
| browser, no build step. |
|
|
| - **Move:** A/D or arrows · **Jump:** Space/W (coyote time included) |
| - **E:** talk to the Architect at checkpoints · **R:** restart after winning |
| - Seal all **8 Bifrost event cubes**, then reach the **Bifrost terminal** |
| - Gaps respawn you; HUD tracks sealed events + ledger integrity |
|
|
| Verified: `node --check` clean, headless DOM-stubbed run of the full |
| game loop (boot, run, jump, all 8 pickups, NPC dialogue open/close, |
| win banner, reset) — all OK. Layout composited against the real art |
| and visually inspected. |
|
|
| ## Build it for real — `UnrealProject/` (C# / UnrealSharp) |
|
|
| Unreal Engine 5.5+ project using **C# via UnrealSharp** + Paper2D: |
|
|
| - `Snapkitty2D.uproject` — module `Snapkitty2D`, depends on |
| `Paper2D`, `EnhancedInput`, `UnrealSharpCore` |
| - `Source/Snapkitty2D/`: |
| - `SnapkittyPlayer.cs` — plane-locked 2D character controller, |
| run/jump, flipbook animation states (idle/run/jump) |
| - `ArchitectNPC.cs` — dialogue NPC, talk radius, briefing lines |
| - `BifrostPickup.cs` — bobbing/spinning collectible event cube |
| - `SnapkittyGameMode.cs` — sealed-event counter, win condition, |
| Blueprint events for UI/fanfare |
| - `SnapkittyHUD.cs` — SNAP-OS styled HUD bindings (event counter, |
| integrity bar, timed dialogue box) |
| - `Config/DefaultEngine.ini` — 2D-oriented defaults |
| |
| Open the `.uproject` in UE5, import `art/` as Paper2D sprites, subclass |
| the C# classes in Blueprints, build `L_BifrostRunner`. |
|
|
| ## Art — `art/` |
|
|
| | file | role | |
| |---|---| |
| | `kitten.png` | player sprite (background-removed cutout) | |
| | `suited-man.png` | Architect NPC sprite (background-removed cutout) | |
| | `civilization.jpg` | parallax world backdrop | |
| | `snap-os.jpg` | HUD/title-screen reference | |
| | `*.jpg` originals | kept as fallback sources | |
|
|
| (Cutouts produced with `rembg`; the web prototype auto-falls back to |
| the `.jpg` originals if a `.png` is missing.) |
