bool is_point_inside\ (\ point: Vector2\ ) const 🔗

Returns true if point falls inside the polygon area.

    var polygon_path_finder = PolygonPathFinder.new()
    var points = [Vector2(0.0, 0.0), Vector2(1.0, 0.0), Vector2(0.0, 1.0)]
    var connections = [0, 1, 1, 2, 2, 0]
    polygon_path_finder.setup(points, connections)
    print(polygon_path_finder.is_point_inside(Vector2(0.2, 0.2))) # Prints true
    print(polygon_path_finder.is_point_inside(Vector2(1.0, 1.0))) # Prints false

    var polygonPathFinder = new PolygonPathFinder();
    Vector2[] points =
    [
        new Vector2(0.0f, 0.0f),
        new Vector2(1.0f, 0.0f),
        new Vector2(0.0f, 1.0f)
    ];
    int[] connections = [0, 1, 1, 2, 2, 0];
    polygonPathFinder.Setup(points, connections);
    GD.Print(polygonPathFinder.IsPointInside(new Vector2(0.2f, 0.2f))); // Prints True
    GD.Print(polygonPathFinder.IsPointInside(new Vector2(1.0f, 1.0f))); // Prints False

void setup\ (\ points: PackedVector2Array, connections: PackedInt32Array\ ) 🔗

Sets up PolygonPathFinder with an array of points that define the vertices of the polygon, and an array of indices that determine the edges of the polygon.

The length of connections must be even, returns an error if odd.

    var polygon_path_finder = PolygonPathFinder.new()
    var points = [Vector2(0.0, 0.0), Vector2(1.0, 0.0), Vector2(0.0, 1.0)]
    var connections = [0, 1, 1, 2, 2, 0]
    polygon_path_finder.setup(points, connections)

    var polygonPathFinder = new PolygonPathFinder();
    Vector2[] points =
    [
        new Vector2(0.0f, 0.0f),
        new Vector2(1.0f, 0.0f),
        new Vector2(0.0f, 1.0f)
    ];
    int[] connections = [0, 1, 1, 2, 2, 0];
    polygonPathFinder.Setup(points, connections);
