So im pretty new to godot and im trying to let my player rotate smoothly in the direction hes moving to.
Right now he just clips between the 8 possible moving directions, so im basicly trying to have a smooth transition between those directions. I tried a couple different things but none of them worked, most of the time the character just rotates permanently or in random directions

extends CharacterBody3D

const NormalSpeed := 180
const SprintSpeed := 360
const SneakSpeed := 90

const fall_acce := 60

const jump_impulse := 1000

var target_velocity := Vector3.ZERO

#-------------------------------------------------------------------------------

func _physics_process(delta):
    
    #Stores the input direction
    var direction := Vector3.ZERO
    
    #just checking for input and BASIC moving based on that
    if Input.is_action_pressed("m_forward"):
        direction.x += 1
    if Input.is_action_pressed("m_backward"):
        direction.x -= 1
    if Input.is_action_pressed("m_left"):
        direction.z -= 1
    if Input.is_action_pressed("m_right"):
        direction.z += 1
        
    #Normalizing
    if direction != Vector3.ZERO:
        direction = direction.normalized()
        $Pivot.basis = Basis.looking_at(direction)
        
    
    
    if not is_on_floor(): 
        target_velocity.y = target_velocity.y - (fall_acce * delta)
        
    #Extra Movement
    #Sprint
    var speed: int
    if Input.is_action_pressed("m_sprint"):
        speed = SprintSpeed
    else:
        speed = NormalSpeed
        
    #Sneak
    if Input.is_action_pressed("sneak"):
        get_node("CollisionShape3D").disabled = true 
        speed = SneakSpeed
    else:
        get_node("CollisionShape3D").disabled = false 
        
    #Jump
    if is_on_floor() and Input.is_action_just_pressed("jump"):
        target_velocity.y = jump_impulse * delta
        
    
        
    
    target_velocity.x = direction.x * speed * delta
    target_velocity.z = direction.z * speed * delta
        
    
    
    velocity = target_velocity
