Member Data Documentation

readonly int [] Rotations

Initial value:
= {
1, 0,
0, 1,
0, 1,
-1, 0,
-1, 0,
0, -1,
0, -1,
1, 0
}

Matrices for rotation.

Each group of 4 elements is a 2x2 matrix. The XZ position is multiplied by this. So

//A rotation by 90 degrees clockwise, second matrix in the array
(5,2) * ((0, 1), (-1, 0)) = (2,-5)
int x
int y
