I want an object, an eye, in this case, to smoothly rotate to look at the player. How would I achieve this? A full code example would be greatly appreciated!

you can use move_toward to smoothly rotate to the player.
func _process(delta: float) -> void:
# gets the angle we want to face
angle_to_player = global_position.direction_to(player_position).angle()
# slowly changes the rotation to face the angle
rotation = move_toward(rotation, angle_to_player, delta)
var angle_to_player
func _physics_process(delta):
angle_to_player = global_position.direction_to(player_body.position).angle()
$EyeAxis.rotation = move_toward($EyeAxis.rotation, angle_to_player, delta)
With the following code I get errors:
“Cannot find property “angle” on base “Vector3”.”
“Function “angle()” not found in base Vector3.”
Any clue what I’m doing wrong?

Vector3 doesn’t have an angle method unlike Vector2, you can do this instead
angle_to_player = global_position.angle_to(player_body.position)
tell me if that works, I haven’t tested it myself yet

A simpler method than the other answer would be to work directly on the basis:
func _process(delta):
var target_vector = global_position.direction_to(player_position)
var target _basis= Basis.looking_at(target_vector)
basis = basis.slerp(target_basis, 0.5)
This works perfectly! Thanks

This should be equivalent in C#
var targetVector = GlobalPosition.DirectionTo(playerPosition);
// Throws exception if targetVector == 0
if (targetVector == Vector3.Zero)
{
return;
}
var target = Basis.LookingAt(targetVector);
Basis = Basis.Slerp(target, 0.1f);
