al_build_transform(3alleg5) | al_build_transform(3alleg5) |
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
Note: this function was previously documented to be equivalent to a different (and more useful) order of operations: identity, scale, rotate, translate.
