I used random generation of value in one of my project and when i tried to use that in my timer node it worked perfectly at first, but later it crushed and said that it was an null instance, when i used just timer instance. I tried to rewrite code (the part responsible for it, I mean), delete and add the timer node and restart the godot. I didn't restart the compuer though. Can anyone help me fix it?
my code is:
extends KinematicBody2D
var rng2 = RandomNumberGenerator.new()
var rng = RandomNumberGenerator.new()
var offset = Vector2.AXIS_Y
var direction = Vector2.AXIS_X
var velocity = Vector2.ZERO
var left = Vector2.LEFT
var right = Vector2.RIGHT
var down = Vector2.DOWN
export var health = 1
var turn = Turn
var diection = "right"
var speed_multiplayer = 0.1
var speed = 0.5
var death_effect_sound = false
onready var Scoree = $"/root/Score"
onready var winn = $"/root/WinnDetector"
onready var animplay = $SoundPlayer
onready var tamir = $AttackTimerr
signal higher_score
func _ready():
rng.randomize()
var my_random_number = rng.randf_range(6.0, 12.0)
tamir.start(my_random_number)
offset += 2
velocity.x = 1
health = rng2.randf_range(1.0, 2.0)
func _physics_process(delta):
if health <= 0:
create_death_effect()
move_and_collide(velocity)
if diection == "right":
velocity.x = speed
elif diection == "left":
velocity.x =0 - speed
func create_death_effect():
var Death_effect = load("res://Enemy/Death Effect Enemy.tscn")
var df = Death_effect.instance()
var world = get_tree().current_scene
get_parent().add_child(df)
df.global_position = global_position
Scoree.score += 5
winn.enemy_count -= 1
death_effect_sound = true
queue_free()
func _on_Hurtbox_area_entered(area):
emit_signal("higher_score")
health -= 1
var explosion = load("res://Effect/Explosion.tscn")
var ex = explosion.instance()
var world = get_tree().current_scene
get_parent().add_child(ex)
ex.global_position = global_position
animplay.play("Hit")
func _on_Area2D_area_entered(area):
speed = speed + speed * speed_multiplayer
global_position.y += 3
if diection == "left":
diection = "right"
elif diection == "right":
diection = "left"
func _on_KillTimer_timeout():
queue_free()
func _on_AttackTimer_timeout():
var my_random_number = rng.randf_range(6.0, 12.0)
tamir.start(my_random_number)
var Bullet = load("res://Enemy/Enemy Bullet.tscn")
var bullet = Bullet.instance()
var world = get_tree().current_scene
get_parent().add_child(bullet)
bullet.global_position = global_position
animplay.play("attack")
the error was
Attempt to call a function 'start' in base 'null instance' on a null instance
