# /Scenes — the runtime scenes

Unlike `/Tools`, these are what actually runs the game. They **do not generate the world** — they
load and interpret an existing `.dat` blueprint.

## `Main.tscn` — the 3D world

| Node | What it is |
|---|---|
| `World` (`Node3D`) | Root. Carries `ServerChunkManager.cs` — this is what builds the world. |
| `Camera3D` | Child of `World`. The server teleports it above the Capitol at startup. |
| `DirectionalLight3D` | Sunlight. |
| `WorldEnvironment` | Ambient light. |

### Running it

**Open this scene and press F6** (*Run Current Scene*).

⚠ **Do not press F5.** The project's main scene is the 2D map generator, not this — F5 regenerates
the whole world and overwrites your `.dat`.

At boot the manager reads `ServerConfig.json`, loads `MapData_Seed_<WorldSeed>.dat` from `user://`,
finds the Capitol, and builds a `(2 × ChunkRadius)²` grid of chunks around it. **Set `ChunkRadius` to
4–8 first** unless you specifically want the full 4,096-chunk, ~3.6 GB boot.

If the seed in `ServerConfig.json` doesn't match an existing `.dat`, the load fails and you get an
empty scene.

### Two things that will confuse you

- **The camera cannot be moved at runtime.** There is no camera controller and no input handling
  anywhere in the codebase. The server overrides whatever transform you save here, placing the camera
  above the Capitol looking straight down — which is also a degenerate `LookAt`, so its roll is
  arbitrary and Godot logs a warning. To view from elsewhere you have to edit the teleport code.
- **Moving the `World` node moves the entire world.** Chunks are added as its children, so a stray
  drag in the editor offsets all rendered terrain. If everything looks displaced, check `World`'s
  transform is zeroed.

## `MapCaptureTool.tscn`

A `SubViewportContainer` wrapping `Tools/Scenes/MapPreview.tscn` at 4096×4096. It exists so the map
can be rendered offscreen at full resolution regardless of monitor size. Only needed for the PNG
snapshot path — `MapPreview.tscn` generates the `.dat` on its own.

## Not here yet
No player scene, no UI, no menu. `Main.tscn` is currently a viewer, not a game.
