NAME
itofix - Converts an integer to fixed point. Allegro game programming library. SYNOPSIS
#include <allegro.h> fixed itofix(int x); DESCRIPTION
Converts an integer to fixed point. This is the same thing as x<<16. Remember that overflows (trying to convert an integer greater than 32767) and underflows (trying to convert an integer lesser than -32768) are not detected even in debug builds! The values simply "wrap around". Example: fixed number; /* This conversion is OK. */ number = itofix(100); ASSERT(fixtoi(number) == 100); number = itofix(64000); /* This check will fail in debug builds. */ ASSERT(fixtoi(number) == 64000); RETURN VALUE
Returns the value of the integer converted to fixed point ignoring overflows. SEE ALSO

NAME
ex3d - 3d 'bouncy cubes' demo. Allegro game programming library. SYNOPSIS
#include <allegro.h> Example ex3d DESCRIPTION
This program demonstrates how to use the 3d matrix functions. It isn't a very elegant or efficient piece of code, but it does show the stuff in action. It is left to the reader as an exercise to design a proper model structure and rendering pipeline: after all, the best way to do that sort of stuff varies hugely from one game to another. The example first shows a screen resolution selection dialog. Then, a number of bouncing 3d cubes are animated. Pressing a key modifies the rendering of the cubes, which can be wireframe, the more complex transparent perspective correct texture mapped version, and many other. SEE ALSO
