AW_AVATAR_YAW
Type
Integer
Description
Yaw of a users avatar.
Notes
This is the value set for AW_MY_YAW when the user called aw_state_change. It is given in units of one tenth of a degree and should not be assumed to be in the range of 0 to 3599.
For positive values of yaw modulo 3600: A yaw of 0 is facing directly north, 900 is facing west, 1800 is facing south, and 2700 is facing east.
For negative values of yaw modulo 3600: A yaw of 0 is facing directly north, -2700 is facing west, -1800 is facing south, and -900 is facing east.
For SDK build 27, world build 44, browser build 430; and later: It is also used by aw_avatar_set to force users into changing the yaw of their avatar.
Range
When the user is a browser:
| Minimum: | -3599 tenths of a degree |
| Maximum: | 3599 tenths of a degree |
When the user is a bot:
| Minimum: | -2147483648 tenths of a degree |
| Maximum: | 2147483647 tenths of a degree |
Usage
void handle_avatar_change (void)
{
int yaw = aw_int (AW_AVATAR_YAW);
/* put angles in the -3599 to 3599 range */
yaw = yaw % 3600;
/* turn negative angles into positive, to have a single way of telling the direction */
if (yaw < 0)
yaw = yaw + 3600;
printf ("%s is facing ", aw_string (AW_AVATAR_NAME));
if (yaw < 450 || yaw >= 3150)
printf ("north\n");
else if (yaw >= 450 && yaw < 1350)
printf ("west\n");
else if (yaw >= 1350 && yaw < 2250)
printf ("south\n");
else if (yaw >= 2250 && yaw < 3150)
printf ("east\n");
