help me convert my player script to use this base;*

extends Node
class_name PlayerBase

const MAX_HEALTH = 10


var health: int = MAX_HEALTH
var speed: float = 5.0
var jump_strength: float = 4.5

signal health_changed(new_health)

func _ready() -> void:
	initialize_ui()

func initialize_ui() -> void:
	var player_lifebar: ProgressBar = get_tree().current_scene.get_node("HUD/PlayerLifeBar")
	player_lifebar.max_value = MAX_HEALTH
	player_lifebar.value = health

func set_health(value: int) -> void:
	health = clamp(value, 0, MAX_HEALTH)
	update_health_ui()
	emit_signal("health_changed", health)

func update_health_ui() -> void:
	var player_lifebar: ProgressBar = get_tree().current_scene.get_node("HUD/PlayerLifeBar")
	player_lifebar.value = health

func take_damage(damage: int) -> void:
	set_health(health - damage)

func heal(amount: int) -> void:
	set_health(health + amount)

func move(input_dir: Vector2) -> void:
	pass  # To be implemented by child classes (2D / 3D)

func attack() -> void:
	pass  # To be implemented by child classes (2D / 3D)



ny base:
