NAME¶

al_build_transform - Allegro 5 API

SYNOPSIS¶

#include <allegro5/allegro.h>
void al_build_transform(ALLEGRO_TRANSFORM *trans, float x, float y,


   float sx, float sy, float theta)
    

DESCRIPTION¶

Builds a transformation given some parameters. This call is equivalent to calling the transformations in this order: make identity, rotate, scale, translate. This method is faster, however, than actually calling those functions.

Parameters:

•

trans - Transformation to alter

•

x, y - Translation

•

sx, sy - Scale

•

theta - Rotation angle in radians
