containsPoint method

  1. @override
bool containsPoint(
  1. Vector2 point
)
override

Whether this node's hit area contains point.

Override to opt into hitTest. Plain nodes never match.

Implementation

@override
bool containsPoint(Vector2 point) {
  final adjusted = toLocal(point);

  switch (shape) {
    case Rectangle(:final size):
      if (size.x <= 0 || size.y <= 0) return false;

      return adjusted.x >= 0 && //
          adjusted.x <= size.x &&
          adjusted.y >= 0 &&
          adjusted.y <= size.y;

    case Circle(:final radius):
      final dx = adjusted.x - radius;
      final dy = adjusted.y - radius;
      return dx * dx + dy * dy <= radius * radius;
  }
}
