Demo — Simple Hamiltonian

Run the demo

The demo is a ready-to-play scene. Open Assets/SimpleHamiltonian/Scenes/, open the demo scene, and press Play. The landing menu appears first — pick a mode and grid, hit Play.

Built-in pipelineThe demo scene targets the Built-in render pipeline. On URP/HDRP, run Unity's material converter on the demo materials.

Controls

Square: WASD / arrows · Hex: QE AD ZC (corner cluster) · hold & drag the mouse to draw the path · R reset · H hide legend · F auto-solve.

During auto-solve, only R responds (cancel) — everything else is locked so it can't fight the playback.

Random generates a fresh set on a background thread behind a progress bar, then plays it. Puzzle Packs plays a curated Square or Hex pack. Solving the last level shows the win screen; any key / click / Play Again restarts.

Skin it with your art

On the LevelRenderer3D in the scene, drop your own Tile Prefab (square) and Hex Tile Prefab (pointy-top, 1.0 flat-to-flat wide, pivot centered). Fit To Cell auto-scales any prefab to the grid; Tile Euler fixes Z-up Blender imports. State is shown by color: dark = empty, green = walked, blue = start, orange = end; checkpoints light up only when they're next.

Empty prefab slots fall back to colored primitives, so the scene runs with zero art.

The parts

Component	Role
`DemoGame`	The controller. Plays a list of puzzles; `Play(list)` / `Play(provider)`.
`LevelGame`	Pure-C# play brain (events: LevelLoaded, PathChanged, LevelComplete, GameCompleted).
`LevelRenderer3D`	Spawns tiles, draws the path by color; square & hex layout.
`PlayerController3D`	Grid-step + drag input, auto-solve trigger.
`DemoMenu` / `DemoHud`	Landing menu (with loading) / HUD (legend, stats, win).
`DemoCameraFit` / `DemoEnvironment` / `DemoAudio`	Angled auto-framing camera / shadows+fog+ground / procedural SFX.

All of this is plain example code — read it, copy it, or replace it with your own.

Rebuild it / set up your own scene

The demo scene ships pre-built — open it and press Play; you never need the builders to use it. To re-skin, drop your own prefabs onto LevelRenderer3D / PlayerController3D (empty slots fall back to primitives).

One-click builders that recreate each piece (3D demo, HUD, menu) are included in Assets/SimpleHamiltonian/Editor/Tools but kept off the menu. To use one, uncomment its [MenuItem] line — it then appears under Window ▸ Living Failure ▸ Simple Hamiltonian ▸ Demo Setup.
