### Example Usage of ProceduralToolkit in Unity

Source: https://github.com/syomus/proceduraltoolkit/blob/master/README.md

Demonstrates how to import and use the ProceduralToolkit namespace in a Unity C# script. This example logs a random color generated by the RandomE.colorHSV utility. It requires Unity 2022.3 LTS or later and assumes the toolkit is installed.

```csharp
using UnityEngine;
using ProceduralToolkit;

public class ReadmeExample : MonoBehaviour
{
    private void Update()
    {
        Debug.Log(string.Format("<color=#{0}>{0}</color>", RandomE.colorHSV.ToHtmlStringRGB()));
    }
}
```

### Generate Procedural Building in C#

Source: https://context7.com/syomus/proceduraltoolkit/llms.txt

Demonstrates how to generate a single procedural building using the BuildingGenerator. It involves setting up facade and roof strategies, defining the building's foundation polygon, configuring various parameters like the number of floors, roof type, and color palette, and finally calling the Generate method. Dependencies include UnityEngine, ProceduralToolkit, and System.Collections.Generic.

```csharp
using UnityEngine;
using ProceduralToolkit;
using ProceduralToolkit.Buildings;
using System.Collections.Generic;

public class BuildingExample : MonoBehaviour
{
    void GenerateBuilding()
    {
        // Create building generator
        var generator = new BuildingGenerator();

        // Set up facade strategies
        var facadePlanner = ScriptableObject.CreateInstance<FacadePlanner>();
        var facadeConstructor = ScriptableObject.CreateInstance<FacadeConstructor>();
        generator.SetFacadePlanner(facadePlanner);
        generator.SetFacadeConstructor(facadeConstructor);

        // Set up roof strategies
        var roofPlanner = ScriptableObject.CreateInstance<RoofPlanner>();
        var roofConstructor = ScriptableObject.CreateInstance<RoofConstructor>();
        generator.SetRoofPlanner(roofPlanner);
        generator.SetRoofConstructor(roofConstructor);

        // Define building footprint (foundation polygon)
        List<Vector2> foundation = new List<Vector2>
        {
            new Vector2(-5f, -5f),
            new Vector2(5f, -5f),
            new Vector2(5f, 5f),
            new Vector2(-5f, 5f)
        };

        // Configure building parameters
        var config = new BuildingGenerator.Config
        {

                frameColor = ColorE.white * 0.7f,
                glassColor = new Color(0.6f, 0.8f, 1f, 0.5f)
            }
        };

        // Generate the building
        Transform building = generator.Generate(
            foundationPolygon: foundation,
            config: config,
            parent: transform
        );

        Debug.Log($"Generated {config.floors}-floor building");
    }

    void GenerateMultipleBuildings()
    {
        // Reuse generator for efficiency
        var generator = new BuildingGenerator();

        for (int x = 0; x < 5; x++)
        {
            for (int z = 0; z < 5; z++)
            {
                Vector3 position = new Vector3(x * 15f, 0, z * 15f);

                // Random foundation size
                float size = RandomE.Range(4f, 7f);
                List<Vector2> foundation = new List<Vector2>
                {
                    new Vector2(-size, -size),
                    new Vector2(size, -size),

                    }
                };

                Transform building = generator.Generate(foundation, config, transform);

Source: https://context7.com/syomus/proceduraltoolkit/llms.txt

Demonstrates creating, converting, and manipulating colors using the ColorHSV class from Procedural Toolkit. Supports conversion to Unity's Color, modification of HSV components, generation of color schemes, and use of predefined HTML colors. Requires Unity and the Procedural Toolkit library.

```csharp
using UnityEngine;
using ProceduralToolkit;

public class ColorExample : MonoBehaviour
{
    void Start()
    {
        // Create color in HSV space
        ColorHSV baseColor = new ColorHSV(
            h: 200f,      // Blue hue
            s: 0.8f,      // High saturation
            v: 0.9f,      // Bright
            a: 1f         // Opaque
        );

        // Convert to Unity Color
        Color rgbColor = baseColor.ToColor();

        // Modify HSV components
        ColorHSV darker = baseColor.WithV(0.5f);
        ColorHSV desaturated = baseColor.WithS(0.3f);
        ColorHSV shifted = baseColor.WithOffsetH(30f);

        // Generate color schemes
        ColorHSV complementary = baseColor.GetComplementary();
        ColorHSV[] triadic = baseColor.GetTriadic();
        ColorHSV[] tetradic = baseColor.GetTetradic();

        // Use predefined HTML colors
        Color silver = ColorE.silver;
        Color aqua = ColorE.aqua;
        Color crimson = ColorE.crimson;

        // Modify color components
        Color withAlpha = silver.WithA(0.5f);
        Color brightened = aqua * 1.5f;
        Color darkened = crimson / 2f;

        // Apply to material
        var renderer = GetComponent<Renderer>();
        renderer.material.color = baseColor.ToColor();
    }

    void CreateRainbow()
    {
        int colorCount = 7;
        for (int i = 0; i < colorCount; i++)
        {
            float hue = (360f / colorCount) * i;
            ColorHSV color = new ColorHSV(hue, 1f, 1f);

            // Create colored object
            GameObject obj = GameObject.CreatePrimitive(PrimitiveType.Cube);
            obj.transform.position = new Vector3(i * 2f, 0, 0);
            obj.GetComponent<Renderer>().material.color = color.ToColor();
        }
    }
}

{
    void ArrayOperations()
    {
        int[] array = { 1, 2, 3, 4, 5, 6, 7, 8, 9 };

        // Looped getters (wrap around at boundaries)
        int looped = array.GetLooped(10);      // Gets index 1 (10 % 9)
        int negative = array.GetLooped(-1);     // Gets last element

        // Looped setters
        array.SetLooped(10, 999);               // Sets index 1

        // Shuffle collection
        array.Shuffle();

        List<string> list = new List<string> { "a", "b", "c", "d" };
        list.Shuffle();

        Debug.Log($"Shuffled: {string.Join(", ", array)}");
    }

        int width = 10;
        int height = 10;
        int[,] grid = new int[width, height];

        // Set up some walls
        for (int x = 3; x < 7; x++)
        {
            grid[x, 5] = 1; // Wall
        }

        // Flood fill using 4-connectivity
        var filled = new HashSet<Vector2Int>();

        ArrayE.FloodFill4(

            isValidCell: (x, y) =>
            {
                // Valid if in bounds and not a wall
                return x >= 0 && x < width &&
                       y >= 0 && y < height &&
                       grid[x, y] != 1;
            },
            floodCell: (x, y) =>
            {
                filled.Add(new Vector2Int(x, y));
                grid[x, y] = 2; // Mark as filled
            }
        );

        Debug.Log($"Filled {filled.Count} cells");

        // 8-connectivity flood fill (includes diagonals)
        var filled8 = new HashSet<Vector2Int>();
        ArrayE.FloodFill8(
            startX: 0,
            startY: 0,
            width: width,
            height: height,
            isValidCell: (x, y) => grid[x, y] != 1,
            floodCell: (x, y) => filled8.Add(new Vector2Int(x, y))
        );
    }

    void PracticalFloodFill()

        // Use for terrain region detection
        int mapWidth = 50;
        int mapHeight = 50;
        bool[,] walkable = new bool[mapWidth, mapHeight];

        // ... populate walkable areas ...

        // Find all connected walkable regions
        var regions = new List<HashSet<Vector2Int>>();
        bool[,] visited = new bool[mapWidth, mapHeight];

        for (int x = 0; x < mapWidth; x++)
        {
            for (int y = 0; y < mapHeight; y++)
            {

                {
                    var region = new HashSet<Vector2Int>();

                    ArrayE.FloodFill4(
                        x, y, mapWidth, mapHeight,
                        isValidCell: (cx, cy) =>
                            walkable[cx, cy] && !visited[cx, cy],
                        floodCell: (cx, cy) =>
                        {
                            visited[cx, cy] = true;
                            region.Add(new Vector2Int(cx, cy));
                        }
                    );

                    regions.Add(region);
                }
            }
        }

{
    void VectorOperations()
    {
        Vector2 a = new Vector2(1f, 0f);
        Vector2 b = new Vector2(0f, 1f);

        // Perpendicular dot product (2D cross product, useful for winding)
        float perpDot = VectorE.PerpDot(a, b);
        Debug.Log($"Perp dot: {perpDot}"); // 1.0

        // Get 360-degree signed angle
        float angle360 = VectorE.Angle360(a, b);
        Debug.Log($"360 angle: {angle360}"); // 90

        // Rotate vectors
        Vector2 rotatedCW = a.RotateCW(45f);
        Vector2 rotatedCCW = a.RotateCCW(45f);
        Vector2 rotated90CW = a.RotateCW90();
        Vector2 rotated90CCW = a.RotateCCW90();

        Debug.Log($"Rotated CW 45°: {rotatedCW}");
        Debug.Log($"Rotated CCW 45°: {rotatedCCW}");

        // Swizzle operations (reorder components)
        Vector2 vec2D = new Vector2(1f, 2f);
        Vector3 xyz = vec2D.ToVector3XY(z: 3f);  // (1, 2, 3)
        Vector3 xzy = vec2D.ToVector3XZ(y: 3f);  // (1, 3, 2)
        Vector3 yxz = vec2D.ToVector3YZ(x: 3f);  // (3, 1, 2)

        Debug.Log($"XY swizzle: {xyz}");
        Debug.Log($"XZ swizzle: {xzy}");
    }

    void GeometricVectorUse()
    {
        // Use perpendicular dot for point-line side test
        Vector2 lineStart = Vector2.zero;
        Vector2 lineEnd = new Vector2(5f, 0f);
        Vector2 point = new Vector2(2f, 1f);

        Vector2 lineDir = (lineEnd - lineStart).normalized;
        Vector2 toPoint = point - lineStart;
        float side = VectorE.PerpDot(lineDir, toPoint);

        if (side > 0)
            Debug.Log("Point is on the left");
        else if (side < 0)
            Debug.Log("Point is on the right");
        else
            Debug.Log("Point is on the line");

        // Calculate angle for AI steering
        Vector2 forward = transform.right;
        Vector2 toTarget = (Vector2)(target.position - transform.position);
        float angle = VectorE.Angle360(forward, toTarget.normalized);

        // Determine turn direction
        if (angle > 180f)
            Debug.Log("Turn right");
        else if (angle < 180f && angle > 0f)
            Debug.Log("Turn left");
    }
