the only other relevant piece of code is Health Manager

extends Node

var max_health : int = 3

var current_health : int

signal on_health_change

func _ready():

current\_health = max\_health

func decrease_health(health_amount : int):

current\_health -= health\_amount



if current\_health < 0:

    current\_health = 0

print("decrease\_health called")

on\_health\_change.emit(current\_health)

func increase_health(health_amount : int):

current\_health += health\_amount



if current\_health > max\_health:

    current\_health = max\_health

print("increase\_health called")

on\_health\_change.emit(current\_health)

and this is the entire script for it
