from the manual:

Quote:


For orienting the entity in a certain direction or towards a certain point in space, use the vec_to_angle function.




so,

Code:

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
}
