A library for creating grids of hexagons. May be rendered on a canvas or similar. I've only implemented grids in a hexagonal formation so far. I've taken a lot of inspiration from the blog posts at: https://www.redblobgames.com/grids/hexagons/ to write this library.
Typical usage:
Create a grid:
final Grid grid = new GridBuilder()
.setRadius(3)
.setFormation(GridFormation.HEXAGONAL)
.setOrientation(Hexagon.Orientation.POINTY)
.build();
Create a GridLayout (this object is required to obtain the points used for rendering):
// For a canvas of 1024x768, where 50 is size of each hexagon
GridLayout gl = new GridLayout(1024/2, 768/2, 50);
Obtain points for each Hexagon:
for (Hexagon h : grid.getHexagons()) {
List<Point> points = h.getPoints(gl);
}
This example would render the following grid (displayed in a simple Swing GUI):
