vec_to_angle (ANGLE* ang, VECTOR* dir);

Computes the pan and tilt angles of a direction vector, and places them into the pan and tilt parameters of an Euler angle. Very useful for trading an angle for a direction, thus computing the angles to a target.

Parameters:

ang Euler angle to be calculated.
dir direction vector.

Returns:

ang

Modifies:

ang

Speed:

Fast

Example:

function turn_towards_target()
{
  // get the direction from the entity MY to the entity YOU
  vec_set(temp,your.x); 
  vec_sub(temp,my.x);
  vec_to_angle(my.pan,temp); // now MY looks at YOU
}
