Quick Reference Example Usage:

extends CharacterBody2D

const SPEED = 300.0
const JUMP_VELOCITY = -400.0

func _physics_process(delta):
    # Gravity
    if not is_on_floor():
        velocity.y += get_gravity().y * delta
    
    # Jump
    if Input.is_action_just_pressed("ui_accept") and is_on_floor():
        velocity.y = JUMP_VELOCITY
    
    # Movement
    var direction = Input.get_axis("ui_left", "ui_right")
    if direction:
        velocity.x = direction * SPEED
    else:
        velocity.x = move_toward(velocity.x, 0, SPEED)
