Hello guys I have a problem with my game. I make a space shooter and i made a flash shader when the enemies get hit. The problems came when i try the game and every instance of my enemies start the shader when one get hit. I will leave the code below:
Enemy
extends Area2D
export var health = 100
export var speed = 50
export var fire_rate = 2
export var points = 10
var fire_rate_timer = Timer.new()
var fly_can_shoot = true
var hit_animation = preload("res://Hit_animation.tscn")
func _ready():
$Skin.play()
#set the timer for the fire rate
set_timer()
EventBus.connect("hit_animation",self,"on_hit_animation")
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 fly_can_shoot == true :
Methods.play_sound("Shoot")
create_fly_projectile(Global.Fly_projectile,global_position)
fly_can_shoot = false
fire_rate_timer.start()
print("shoot")
func _on_Fly_area_entered(area):
health -= 1
check_health()
if area.health >= 0:
EventBus.emit_signal("hit_animation")
EventBus.emit_signal("hit")
func on_shoot_timeout():
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)
Global.score += points
EventBus.emit_signal("score")
queue_free()
else:
Methods.play_sound("Hit")
func create_fly_projectile(projectile,location):
var projectile_instance = projectile.instance()
get_parent().add_child(projectile_instance)
projectile_instance.global_position = location + Vector2(-10,0)
print("made")
func on_hit_animation():
var hit_animation_instance = hit_animation.instance()
get_node("Skin").add_child(hit_animation_instance)
hit_animation_instance.play("Flash")
Animation player for the shader
extends AnimationPlayer
var flash_duration_timer = Timer.new()
var flash_duration = 1.0
func _ready():
Global.Hit_animation = self
set_timer()
EventBus.connect("hit",self,"on_hit_start")
func _exit_tree():
Global.Hit_animation = null
func set_timer():
flash_duration_timer.set_one_shot(true)
flash_duration_timer.set_wait_time(flash_duration)
flash_duration_timer.connect("timeout",self,"on_flash_timeout")
add_child(flash_duration_timer)
func on_hit_start():
flash_duration_timer.start()
func on_flash_timeout():
self.stop(true)
I tried finding this on forums but nothing works. It is a way to make the instances independent from each other? for the part when it need to dies work perfectly and i’m confuse why this don’t. Thanks and sorry for my english.
