  • How to only attack first zombie if multiple are in the same spot?

I'm currently trying to develop a Plants Vs Zombies fangame in Godot 4.4. But whenever 2 or more zombies are eating a plant and get hit, they all take damage when I only want the zombie who attacked first to get hit. I've tried searching up solutions but I couldn't figure anything out. Does anyone know how to stop this from happening?

  • Maybe this helps.

    extends Area2D

func _ready():
	connect("on_body_entered", self, "projectile_on_body_entered")

var has_damaged = false
func projectile_on_body_entered(other):
	# If true, then the projectile has already hit something and we can ignore
	# this collision
	if (has_damaged == true):
		return
	
	# Check if the body collided with is something we can damage.
	if (other.has_method("hurt")):
		# Damage the body and do anything else needed here (like sound effects)
		other.hurt()
		# Set has_damaged to true, so we know to ignore damaging
		# anything else
		has_damaged = true
		# free it using queue_free
		queue_free

If the Zombies are inherited from a common scene, are you changing the damage property of a single Zombie's instance, or a property that they share?

    Maybe this helps.

func _ready():
	connect("on_body_entered", self, "projectile_on_body_entered")

var has_damaged = false
func projectile_on_body_entered(other):
	# If true, then the projectile has already hit something and we can ignore
	# this collision
	if (has_damaged == true):
		return
	
	# Check if the body collided with is something we can damage.
	if (other.has_method("hurt")):
		# Damage the body and do anything else needed here (like sound effects)
		other.hurt()
		# Set has_damaged to true, so we know to ignore damaging
		# anything else
		has_damaged = true
		# free it using queue_free
