Question
<Hi. I would appreciate if you could teach me how hitbox and hurtbox class work. I was watching this tutorial and realised hitbox/hurtbox class has been used, and wanted to try implementing to my project. However, hitbox and hurtbox does not detect anything somehow, and i have no idea why. also, i would appreciate if you could teach me how to put different variable (such as enemy damage, bullet damage for hitbox), since script will be shared among other attached nodes. also, is it really best to have hitbox/hurtbox classes rather than just simply making hitbox/hurtbox each time for each nodes(enemies, player, projectiles)
Btw, this is my current code for hitbox/hurtbox. When projectile hitbox enters enemy hurtbox, function knock_back will be called, but never take_damage()
Hitbox:
@icon("res://entities/node/HitBox.svg")
class_name HitBox
extends Area2D
@export var damage := 10
func get_damage() -> int:
print("damage")
return damage + randi() % 7 - 3
Hurtbox:
@icon("res://entities/node/HurtBox.svg")
class_name HurtBox
extends Area2D
func _ready() -> void:
connect("area_entered", Callable(self, "_on_area_entered"))
func _on_area_entered(hitbox: HitBox) -> void:
if owner.has_method("take_damage"):
owner.take_damage(hitbox.get_damage())
if owner.has_method("knock_back"):
owner.knock_back()
Enemy script:
func take_damge(amount: int) -> void:
print("take damage")
health = max(0, health - amount)
if health < 0:
queue_free()
pass
func knock_back() -> void:
$AnimatedSprite2D.material.set_shader_parameter('flash_modifier', 1.0)
await get_tree().create_timer(0.2).timeout
$AnimatedSprite2D.material.set_shader_parameter('flash_modifier', 0.0)
