vg4->misc->cos()

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

SYNTAX

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

FUNCTION PARAMETERS

angle

Angle in degrees

RETURN VALUE

Returns the cosinus-value

DESCRIPTION

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

EXAMPLE

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

#ifndef M_PI
# define M_PI 3.14159265358979323846
#endif

double cosval, radians;
int angle;

angle = 45;

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

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