NAME fixup_datafile – Fixes truecolor images in compiled datafiles. Allegro game programming library. SYNOPSIS #include <allegro.h> void fixup_datafile(DATAFILE *data); DESCRIPTION If you are using compiled datafiles (produced by the dat2s and dat2c utilities) on a platform that doesn’t support constructors (currently any non GCC-based platform), or if the datafiles contain truecolor images, you must call…
NAME fixtorad_r – Constant to convert angles in fixed point format to radians. Allegro game programming library. SYNOPSIS #include <allegro.h> extern const fixed fixtorad_r; DESCRIPTION This constant gives a ratio which can be used to convert a fixed point number in binary angle format to a fixed point number in radians. Example: fixed rad_angle, binary_angle;…
NAME fixtoi – Converts a fixed point to integer with rounding. Allegro game programming library. SYNOPSIS #include <allegro.h> int fixtoi(fixed x); DESCRIPTION Converts fixed point to integer, rounding as required to the nearest integer. Example: int result; /* This will put 33 into `result’. */ result = fixtoi(itofix(100) / 3); /* But this will round…
NAME fixtof – Converts a fixed point to floating point. Allegro game programming library. SYNOPSIS #include <allegro.h> double fixtof(fixed x); DESCRIPTION Converts fixed point to floating point. Example: float result; /* This will put 33.33333 into `result’. */ result = fixtof(itofix(100) / 3); /* This will put 16.66666 into `result’. */ result = fixtof(itofix(100) /…
NAME fixtan – Fixed point tangent of binary angles. Allegro game programming library. SYNOPSIS #include <allegro.h> fixed fixtan(fixed x); DESCRIPTION This function finds the tangent of a value using a lookup table. The input value must be a fixed point binary angle. Example: fixed angle, res_a, res_b; float dif; angle = itofix(37); /* Prove that…
NAME fixsub – Safe function to subtract fixed point numbers clamping underflow. Allegro game programming library. SYNOPSIS #include <allegro.h> fixed fixsub(fixed x, fixed y); DESCRIPTION Although fixed point numbers can be subtracted with the normal ‘-‘ integer operator, that doesn’t provide any protection against overflow. If overflow is a problem, you should use this function…
NAME fixsin – Fixed point sine of binary angles. Allegro game programming library. SYNOPSIS #include <allegro.h> fixed fixsin(fixed x); DESCRIPTION This function finds the sine of a value using a lookup table. The input value must be a fixed point binary angle. Example: fixed angle; int result; /* Set the binary angle to 90 degrees….
NAME fixmul – Multiplies two fixed point values together. Allegro game programming library. SYNOPSIS #include <allegro.h> fixed fixmul(fixed x, fixed y); DESCRIPTION A fixed point value can be multiplied or divided by an integer with the normal `*’ and `/’ operators. To multiply two fixed point values, though, you must use this function. If an…
