al_build_transform3alleg5

Overview

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.
