Usage

Sample code

Create instance

var grid = scene.rexBoard.add.hexagonGrid({
    x: 0,
    y: 0,
    cellWidth: 0,
    cellHeight: 0,
    // size: undefined,
    staggeraxis: 1,
    staggerindex: 1
});

• x, y : World position of origin tile (i.e. tileX = 0, tileY = 0)
• cellWidth : The width of the cell, in pixels.
• cellHeight : The height of the cell, in pixels.
• size : Distance between center to each corner. Get cellWidth and cellHeight from size if this parameter is not undefined.
• staggeraxis
  • 0, or y
  • 1, or x
• staggerindex
  • 0, or even
  • 1, or odd

World position of tile (0, 0)

• Get

  var worldX = grid.x;
  var worldY = grid.y;
  

• Set

  grid.setOriginPosition(worldX, worldY);
  

  or

  grid.x = worldX;
  grid.y = worldY;
  

Cell size

• Get

  var width = grid.width;
  var height = grid.height;
  

• Set

  grid.setCellSize(width, height);
  

  or

  grid.width = width;
  grid.height = height;
  

  or

  grid.setCellRadius(size);
  

  • size : Distance between center to each corner.

Grid type

• Get

  var staggeraxis = grid.staggeraxis;
  var staggerindex = grid.staggerindex;
  

• Set

  grid.setType(staggeraxis, staggerindex);
  

  • staggeraxis
    • 0, or y
    • 1, or x
  • staggerindex
    • 0, or even
    • 1, or odd

Get world position

var worldXY = grid.getWorldXY(tileX, tileY);  // worldXY: {x, y}
// var out = grid.getWorldXY(tileX, tileY, out);

Get tile position

var tileXY = grid.getTileXY(worldX, worldY);  // tileXY: {x, y}
// var out = grid.getTileXY(worldX, worldY, out);
