TGridSys

The bottom most point in the grid where the value of y is minimum.

For each row of tiles performs side effecting function on the r coordinate of the row.

The left most point in the grid where x is minimum.

Number of rows of tile centres. This will be different to the number of rows of sides and and will be different to the number of rows of vertices for HexGrids.

The right most point in the grid where the value of x is maximum.

The top most point in the grid where the value of y is maximum.

the ratio of r => y, when translating from TCoord tile grid coordinates to Pt2 and Vec2s.

The centre point as a Vec2. Not sure why this id implemented here.

flatMaps over each row number.

Height of the tile grid system from furthest tile edge or vertex to furthest tile edge or vertex.

maps over each row number.

Width of the tile grid system from furthest tile edge or vertex to furthest tile edge or vertex.

The centre of this grid in the X axis. this will be equal to the cCen Int value.

The centre of this grid in the y axis. For SqGrids this will be equal to the cCen Int value, but this is not the case for HGrids.

The total number of tile centres in this tile Grid system.
