Godot 4
I need help with my project. My game is a top-down 2d game. I have an enemy ai that chases the player around a little box and I want the enemy to damage the player by 1 hitpoint every time it touches the player (the player has 10 hitpoints), but whenever the enemy touches the player the health does not go down in any way and the enemy just pushes the player. How do I make the player take damage? This is the code for the player:
extends CharacterBody2D
var speed = 200
func _physics_process(delta):
var velocity = Vector2.ZERO
if Input.is_action_pressed("ui_left"):
velocity.x -= speed
if Input.is_action_pressed("ui_right"):
velocity.x += speed
if Input.is_action_pressed("ui_up"):
velocity.y -= speed
if Input.is_action_pressed("ui_down"):
velocity.y += speed
self.velocity = velocity.normalized() * speed
move_and_slide()
var max_health = 10
var current_health = 10
var health_label
func _ready():
# Initialize health_label by getting the reference to the PlayerHealthLabel node
health_label = get_node("PlayerHealthLabel")
func _process(delta):
# Update the health label text
health_label.update_health(current_health, max_health)
func take_damage(damage):
current_health -= damage
Here’s the code for the label:
extends Label
func update_health(current_health, max_health):
self.text = "HP: " + str(max_health) + " / " + str(current_health)
Here’s the code for the enemy:
extends CharacterBody2D
var speed = 150
var player_chase = false
var player = null
func _physics_process(_delta):
if player_chase:
var direction = player.position - position
direction = direction.normalized()
# Move towards the player
position += direction * speed * _delta
func _on_area_2d_body_entered(body):
player = body
player_chase = true
func _on_area_2d_body_exited(_body):
player = null
player_chase = false
var damage_amount = 1
func _on_Enemy_area_entered(area):
if area.is_in_group("player"):
# If colliding with the player, apply damage
area.take_damage(damage_amount)
The left one is the enemy and the right one is the player. The circle collision around the enemy is a collisionshape2d and is supposed to detect the player when it enters the circle and chase it. The square collision around it is to prevent it from clipping into the wall. The label only shows when I play the scene.
