Track Designer

Create valid track layouts for GridRacer.

Track Requirements (from design doc)

Cell Types

enum CellType {
    case track    // Valid racing surface
    case wall     // Collision boundary
    case start    // Starting area
    case finish   // Finish line area
}

Track Structure

struct Track {
    let width: Int
    let height: Int
    let cells: [[CellType]]
    let startPositions: [GridPoint]
    let finishLine: LineSegment
    let lapCount: Int
}

Design Guidelines

1. Closed loop: Track must form a complete circuit
2. Width: Minimum 2 cells wide for passing
3. Start positions: Staggered, equal distance to first turn
4. Finish line: Perpendicular to track direction
5. Corners: Allow multiple racing lines
6. Balance: Fair for all starting positions

Example: Simple Oval (10x8)

..........
.########.
.#......#.
.#......#.
.S......F.
.#......#.
.#......#.
.########.
..........

Legend: .=wall, #=track, S=start, F=finish

Output Format

Generate Swift code for the track:

let simpleOval = Track(
    width: 10,
    height: 8,
    cells: [...],
    startPositions: [GridPoint(2, 4), GridPoint(2, 3)],
    finishLine: LineSegment(start: GridPoint(8, 3), end: GridPoint(8, 5)),
    lapCount: 3
)
