# get\_y\_rotate\_matrix(3alleg)

Construct Y axis rotation matrices. Allegro game programming library.

## NAME

get\_y\_rotate\_matrix, get\_y\_rotate\_matrix\_f - Construct Y axis rotation matrices. Allegro game programming library.

## SYNOPSIS

**#include \<allegro.h\>**

**void get\_y\_rotate\_matrix(MATRIX \*m, fixed r);**

**void get\_y\_rotate\_matrix\_f(MATRIX\_f \*m, float r);**

## DESCRIPTION

Construct Y axis rotation matrices, storing them in m. When applied to a  point, these matrices will rotate it about the Y axis by the specified  angle (given in binary, 256 degrees to a circle format).
