Flipping the sprite when changing directions.

Here’s what I did. Using numeric constants for direction helped with my code:

extends KinematicBody2D

# units are pixels for changing the location of objects on screen
const SPEED = 750
# movement directions
const LEFT = -1
const RIGHT = 1
const STILL = 0

# when the player moves this variable changes
var motion = Vector2()


# processes the physics engine every frame
func _physics_process(delta):
	# get input and set movement
	var direction = STILL
	if Input.is_action_pressed("ui_right"):
		direction += RIGHT
	if Input.is_action_pressed("ui_left"):
		direction += LEFT
	
	motion.x = SPEED * direction
	
	# animate based on the movement
	if direction == STILL:
		$AnimatedSprite.play("idle")
	else:
		$AnimatedSprite.play("run")
	
	# flip the sprite only when direction is left, when still or right set to not flipped
	$AnimatedSprite.flip_h = (direction == LEFT)
	
	# apply movement to the player
	move_and_slide(motion)

const SPEED = 750

var motion = Vector2()

func _physics_process(delta):
	if Input.is_action_pressed("ui_right") and not Input.is_action_pressed("ui_left"):
		motion.x = SPEED #player goes to the right
		$AnimatedSprite.play("run")
		$AnimatedSprite.flip_h = false
	elif Input.is_action_pressed("ui_left") and not Input.is_action_pressed("ui_right"):
		motion.x = -SPEED #player goes to the left negative speed
		$AnimatedSprite.play("run")
		$AnimatedSprite.flip_h = true
	else:
		motion.x = 0 #no movement
		$AnimatedSprite.play("idle")
		$AnimatedSprite.flip_h = false
	move_and_slide(motion)```

Start ahead for now. keeping it simple. I like the const used by the others but leave that for later.

This code also handles jumping animation. :slight_smile:

extends KinematicBody2D

enum Directions {STILL, RIGHT, LEFT = -1, UP = -1}

const SPEED = 750
var movement = Vector2()

func _physics_process(delta):
	var direction = Vector2(Directions.STILL, 0)
	if Input.is_action_pressed("ui_right"):
		direction.x += Directions.RIGHT
		$AnimatedSprite.play("run")
	if Input.is_action_pressed("ui_left"):
		direction.x += Directions.LEFT
		$AnimatedSprite.play("run")
	if Input.is_action_pressed("ui_up"):
		direction.y += Directions.UP
		$AnimatedSprite.play("jump")
	if direction == Vector2(0, 0): # Is still
		$AnimatedSprite.play("idle")
	
	# Flip the sprite when going left
	$AnimatedSprite.flip_h = (direction.x == Directions.LEFT)
	movement.x = SPEED * direction.x
	move_and_slide(movement)

I did it without flip_h :smiley:

extends KinematicBody2D


const SPEED = 750

var motion = Vector2()


func _physics_process(delta):
    if Input.is_action_pressed("ui_right") and not Input.is_action_pressed("ui_left"):
	motion.x = SPEED
	$AnimatedSprite.scale.x = 1  # instead of flip_h
	$AnimatedSprite.play("run")
    elif Input.is_action_pressed("ui_left") and not Input.is_action_pressed("ui_right"):
	motion.x = -SPEED
	$AnimatedSprite.scale.x = -1 # instead of flip_h
	$AnimatedSprite.play("run")
     else:
	motion.x = 0
	$AnimatedSprite.play("idle")
	
     move_and_slide(motion)
