Hey there I have a problem with my project. I created a spawner for my enemy that spawn them every second and when they are added in the scene they shoot a “bullet”(they are flies in a space shooter ) but just the first instacieted fly shoot the rest of them don’t. This is the code:
Fly:
extends Area2D
export var health = 3
export var speed = 100
export var fire_rate = 1
var fire_rate_timer = Timer.new()
func _ready():
$Skin.play()
#set the timer for the fire rate
set_timer()
func _process(delta):
#moving by itself to the left side of the screen
#global_position.x -= speed * delta
#elimate if it's out of the screen
if global_position.x < -10:
queue_free()
#shoot
if Global.fly_can_shoot == true :
Methods.play_sound("Shoot")
EventBus.emit_signal("create_fly_projectile",Global.Fly_projectile,global_position)
Global.fly_can_shoot = false
fire_rate_timer.start()
print("shoot")
func _on_Fly_area_entered(_area):
health -= 1
check_health()
func on_shoot_timeout():
Global.fly_can_shoot =true
func set_timer():
fire_rate_timer.set_one_shot(true)
fire_rate_timer.set_wait_time(fire_rate)
fire_rate_timer.connect("timeout",self,"on_shoot_timeout")
add_child(fire_rate_timer)
func check_health():
#check if enemy he still has health
if health <= 0:
Methods.play_sound("Explosion")
EventBus.emit_signal("create_explosion",Global.Explosion,global_position)
queue_free()
else:
Methods.play_sound("Hit")
Fly_projectile:
extends Area2D
func _process(delta):
#moving by itself to the left side of the screen
global_position.x -= Global.enemies_projectiles["fly_projectile"]["speed"] *delta
#elimate if it's out of the screen
if global_position.x < -10:
queue_free()
func _on_Fly_Projectile_area_entered(_area):
queue_free()
fly_spawner:
extends Timer
export (PackedScene)var Fly
#make an instance of a fly in the boundray of screen
func _on_fly_timeout():
randomize()
var fly = Fly.instance()
get_parent().add_child(fly)
fly.global_position.x = 328
fly.global_position.y = rand_range(8,172)

signal score()

any ideas?
