How do I calculate efficiently the required angle to rotate from one entity to another?
My code is as follows


Code:

---

 
function is_ReturnAngleForTurningToEntity(eAgent,eTarget)
{
	my=eAgent;
	you=eTarget;
	
	// get the direction from the entity MY to the entity YOU
	vec_set(temp,you.x); 
	vec_sub(temp,my.x);
	vec_to_angle(is_tempvec5,temp);

	return(is_tempvec5.pan);
}

FUNCTION rotate_entity(rotate_angle,rotate_speed)
{
	IF (my.pan == rotate_angle) { return; }
	
	result = ang(rotate_angle - my.pan);
	IF (result > 0) { my.pan += rotate_speed * time; }
	IF (result < 0) { my.pan -= rotate_speed * time; }
	IF (ang(rotate_angle - my.pan) < 0 && result > 0) { my.pan = rotate_angle; }
	IF (ang(rotate_angle - my.pan) > 0 && result < 0) { my.pan = rotate_angle; }
}

action player
{
		while(my.pan!=is_tempvec5.pan)
		{
			rotate_entity(is_tempvec5.pan,30*time);
			temp = abs(my.pan - is_tempvec5.pan);
			if(temp<5){break;}
			wait(1);			
		} 
}
