#1

I used single line if statements to help with readability and used a direction variable to x axis movement. I also had a debug print() line in there to help confirm it was working correctly.

Love your use of direction @bhindi1224 so I updated my code to use the same concept. I added some constants to enhance readability.

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
	
	# apply movement to the player
	move_and_slide(motion)

So I made more adjustments to these above codes and introduced enums. :smiley:

They are kind of groups of constants. Enums give constants values starting from 0 so you can use it like I did but you can also assign all values to constants manually.

extends KinematicBody2D

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

const SPEED = 750
var movement = Vector2()

func _physics_process(delta):
	var direction = Directions.STILL
	if Input.is_action_pressed("ui_right"):
		direction += Directions.RIGHT
	if Input.is_action_pressed("ui_left"):
		direction += Directions.LEFT
	if Input.is_action_pressed("ui_up"):
		pass
	movement.x = SPEED * direction
	move_and_slide(movement)
