bool is_point_inside(point: Vector2) const 🔗
如果 point 在多边形区域内部，则返回 true。
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))) # 输出 true
print(polygon_path_finder.is_point_inside(Vector2(1.0, 1.0))) # 输出 false
var polygonPathFinder = new PolygonPathFinder();
Vector2[] points =

int[] connections = [0, 1, 1, 2, 2, 0];
polygonPathFinder.Setup(points, connections);
GD.Print(polygonPathFinder.IsPointInside(new Vector2(0.2f, 0.2f))); // 输出 True

void setup(points: PackedVector2Array, connections: PackedInt32Array) 🔗
使用两个数组设置 PolygonPathFinder：点数组中定义了多边形的顶点，索引数组则决定了多边形的边。
connections 的长度必须为偶数，为奇数时会返回错误。
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);
