How to implement natural rotation of a body, more specifically a plane. in 2D ? I am using a on screen joystick controller to move the body. and whenever I move the joystick to any direction the body instantly turns to that direction. How to rotate the body smoothly in a natural way. ?

(How I want it to rotate) --

(How I don't want it to rotate) --

The part of the code meant for rotation --

	# Angle between the direction in which the body is facing the 
	# joystick_vector (i.e the direction in which the joystick is pushed/stretched)
		
		angle = direction.angle_to(joystick.joystick_vector);
		print(angle);	
		if (angle > 0):
			rotation += deg2rad(unit_rotation * delta);
		elif(angle < 0):
			rotation -= deg2rad(unit_rotation * delta);

The Full code for the Player --

extends KinematicBody2D

export (NodePath) var joystick_path;
export (int) var joystick_speed = 500;
export (int) var normal_speed = 300;
export (float) var unit_rotation = 60

#var speed;
var joystick;

# The direction in which the player is/was moving.
var direction = Vector2()

# The extent to which the player have to rotate
var angle

const JOYSTICK_DEADZONE = 0.4;

func _ready():
	
	$AnimatedSprite.animation = "Normal"
	
	direction = Vector2(0,1)
	
	position = get_viewport().size/2;

	joystick = get_node(joystick_path);



func _physics_process(delta):
	
	# Move based on the joystick, only if the joystick is farther than the dead zone.
	if (joystick.joystick_vector.length() > JOYSTICK_DEADZONE):

		move_and_collide(-joystick.joystick_vector * joystick_speed * delta);

	# Angle between the direction in which the body is facing the 
	# joystick_vector (i.e the direction in which the joystick is pushed/stretched)
	
	angle = direction.angle_to(joystick.joystick_vector);
	print(angle);	
	if (angle > 0):
		rotation += deg2rad(unit_rotation * delta);
	elif(angle < 0):
		rotation -= deg2rad(unit_rotation * delta);	
	
	# When the joystick is not in work.	
	else :
		move_and_collide(-direction * normal_speed * delta);

I haven't done 2D, but you should be able to use this in 2D:

func lerp_angle(from, to, weight):
	return from + short_angle_dist(from, to) * weight

func short_angle_dist(from, to):
	var max_angle = PI * 2
	var difference = fmod(to - from, max_angle)
	return fmod(2 * difference, max_angle) - difference

I put these two functions in an autoload script I have so I can call them from any script. I use this to rotate my character on the Y axis, but I think you can just use the rotation degrees property in 2D.

1.Try Tween, but it is not suitable for excessively moving the joystick. 2.Try to create two planes and follow the movement of the other plane, use follow_method in one planes 3.this code have some problem,if the angle is very small,the plane will shake,you need if angle>SMALL_ROTATION:

    if (angle > 0):
        rotation += deg2rad(unit_rotation * delta);
    elif(angle < 0):
        rotation -= deg2rad(unit_rotation * delta);
