hexToPixel method

Offset hexToPixel(HexCoordinate hex)

将六边形坐标转换为像素坐标（中心点）

Implementation

Offset hexToPixel(HexCoordinate hex) {
  final m = orientation;
  final x = (m.f0 * hex.x + m.f1 * hex.z) * size;
  final y = (m.f2 * hex.x + m.f3 * hex.z) * size;
  return Offset(x + origin.dx, y + origin.dy);
}
