kick.math.Mat2d Class

Defined in: kick/math/Mat2d.js:4
Module: kick.math

Mat2 - 2x3 Matrix A mat2d contains six elements defined as:

[a, b,
 c, d,
 tx,ty]
This is a short form for the 3x3 matrix:

[a, b, 0
 c, d, 0
 tx,ty,1]
The last column is ignored so the array is shorter and operations are faster.
