vg4->misc->sin()

Return sinus-value from angle as integer multiplied with 10000.

SYNTAX

int vg4->misc->sin(int angle)

FUNCTION PARAMETERS

angle

Angle in degrees

RETURN VALUE

Returns the sinus-value

DESCRIPTION

Return sinus-value from angle as integer multiplied with 10000. This function is a replacement for the mathematical sin() function, suitable for network-games.

EXAMPLE

/* Example to get the sinus-value as a double */

#ifndef M_PI
# define M_PI 3.14159265358979323846
#endif

double sinval, radians;
int angle;

angle = 45;

/* builtin sin-function */
sinval = (double)vg4->misc->sin((int)(angle + .5)) / 10000.;
printf("Sinus-value from %d = %.2f\n", angle, sinval);

/* mathematical sin-function */
radians = (double)angle / 360. * (M_PI + M_PI);
sinval = sin(radians);
printf("Sinus-value from %d = %.2f\n", angle, sinval);
