Timer for damage taken

Help Programming

I want to make the code wait like 2 seconds or smth before damaging the player again.

This is the code I have, but it doesn’t work idk why:

extends CharacterBody2D

signal health_depleted

var health = 100.0
const damage_rate = 10.0
var attacking: bool = false
var damage_cactus := 20.0

func _ready():
	%AnimationPlayer.animation_finished.connect(_on_animation_finished)

func _physics_process(delta):
	var direction = Input.get_vector("move_left", "move_right", "move_up", "move_down")
	if attacking:
		velocity = Vector2.ZERO
	else:
		velocity = direction * 400
	move_and_slide()
	
	if not attacking:
		if velocity.length() > 0.0:
			%Bluwee.play_run()
		else:
			%Bluwee.play_idle()
	
	if Input.is_action_just_pressed("attack") and not attacking:
		attacking = true
		handle_attack_animation()
	
	var overlapping_mobs = %Hurtbox.get_overlapping_bodies()
	if overlapping_mobs.size() > 1:
		health -= damage_cactus * overlapping_mobs.size() * delta
		%ProgressBar.value = health
		%Timer.start(2)
		if health <= 0.0:
			health_depleted.emit()

func handle_attack_animation():
	var mouse_position = get_global_mouse_position()
	var vector_to_mouse = (mouse_position - global_position).normalized()
	var angle_to_mouse = vector_to_mouse.angle()  # Angle in radians
	# Convert angle to degrees for easier comparisons
	var angle_in_degrees = rad_to_deg(angle_to_mouse)
	
	# Adjust for top-down orientation (0 degrees = up)
	if angle_in_degrees < 0:
		angle_in_degrees += 360
	
	# Determine animation based on the angle
	if angle_in_degrees >= 315 or angle_in_degrees < 45:
		%Bluwee.play_attack()  # Mouse is above the player
	elif angle_in_degrees >= 45 and angle_in_degrees < 135:
		%Bluwee.play_down_attack()  # Mouse is to the right of the player
	elif angle_in_degrees >= 225 and angle_in_degrees < 315:
		%Bluwee.play_up_attack()  # Mouse is below the player
	elif angle_in_degrees >= 135 and angle_in_degrees < 225:
		%Bluwee.play_left_attack()  # Placeholder for left attacks if needed

func _on_animation_finished(animation: String):
	# Reset attacking flag when the attack animation is done
	if animation in ["right_attack", "back_attack", "front_attack", "left_attack"]:
		attacking = false
		%WarriorBlue.scale.x = 1
		%Bluwee.play_idle()

In this part of your code, you start the timer and … what? Do you wait for it? No. Do you do anything on timer completed - no. You just start a timer.

Instead you need something like this (pseudo code):

# This will be your flag for taking damage
var can_take_damage: bool = true


# inside your function:
	if overlapping_mobs.size() > 1:
		# can we take damage
		if can_take_damage:
			take_damage()
			can_take_damage = false

func take_damage():
		health -= damage_cactus * overlapping_mobs.size() * delta
		%ProgressBar.value = health
		%Timer.start(2)
		if health <= 0.0:
			health_depleted.emit()

# Use the timers timeout signal to allow taking damage again
func _on_timer_timeout():
	can_take_damage = true

Something like that anyway, I hope this helps in some way.

PS the two IF statements I did separately just for clarity to show you how it works, but you can combine them with an AND into a single IF. You could even drop the variable and just see if the timer is running if you chose instead as well.

In short, you have to connect something to the timer’s timeout signal or event.

if you want to wait for a timer, you could write:
await get_tree().create_timer(2.0).timeout
But i think it would not help for the player to get damaged no more than every 2 seconds.

I think I would take a slightly different approach here:

var can_take_damage: bool = true

func _process(delta: float) -> void:
    # some code
    if not can_take_damage:
        return
	if overlapping_mobs.size() > 1:
        can_take_damage = false
		health -= damage_cactus * overlapping_mobs.size() * delta
		%ProgressBar.value = health
		if health <= 0.0:
			health_depleted.emit()
		await get_tree().create_timer(2.0).timeout
        can_take_damage = true
    # some code

With the above approach you won’t check for damage if player received damage within last 2 seconds. After that time, damage can be taken.

The code above may have syntax errors but I tried my best without Godot editor.

I hope this helps you with your problem.
