Question about classes and extending resourcesSootyWhen following along with this lesson, rather than coding the Shooting Mob from scratch I extended the Mob class. I have noticed a couple of times now, If i change say the ready function , it changes the entire ready function. When you want to make changes, say in this instance adding a new shoot_timer.timeout.connect(weapon._shoot) , do I really have to go back to the parent script and copy paste the original code again into the new extended script?
Is there any way to add a single extra line if the rest of the ready or physics process function remains the same? In the following code, I only added 5 lines to update the mob to the shooting mob,
the 2 variables at the top
the shoot_timer connection
weapon.look_at(vector2.Zero) in the body exited function, not sure if this is necessary
and in the physics process the weapon.look_at(_*player.global_*position)
```gdscript
extends Mob
@onready var shoot_timer: Timer = %ShootTimer
@onready var weapon: Weapon_Mob = %Weapon
func _ready() -> void:
shoot_timer.timeout.connect(weapon._shoot)
mob_detector.body_entered.connect(func(body: Node)-> void:
if body is Player:
_player = body
shoot_timer.start()
)
mob_detector.body_exited.connect(func(body: Node)-> void:
if body is Player:
_player = null
shoot_timer.stop()
weapon.look_at(Vector2.ZERO)
)
hit_box.body_entered.connect(_hitbox_entered)
hit_box.body_exited.connect(_hitbox_exited)
hit_timer.timeout.connect(func() -> void:
if contact == true:
_player.health -= damage
)
func _physics_process(delta: float) -> void:
if _player == null:
velocity = velocity.move_toward(Vector2.ZERO, acceleration * delta)
if _player != null:
var direction = global_position.direction_to(_player.global_position)
var distance = global_position.distance_to(_player.global_position) #only need distance for the smoothing algo
var speed = max_speed if distance > 100 else max_speed * distance / 100
var desired_velocity = direction * speed
velocity = velocity.move_toward(desired_velocity, acceleration * delta)
weapon.look_at(_player.global_position)
move_and_slide()
```

inheritance on mob who shootsSandra MoenI used inheritance on the mob that shoots, and solved the shoot-timer a bit differently. It works.
```gdscript
class_name MobShooter
extends Mob
@onready var _shoot_timer: Timer = %ShootTimer
@onready var _weapon_manual: WeaponManual = %WeaponManual
func _ready() -> void:
# super() doesn't work(?)
initialize()
_shoot_timer.timeout.connect(_weapon_manual._shoot)
func _on_detection_entered(body: Node) -> void:
# super() doesn't work(?)
if body is Player:
_shoot_timer.start(0.0) # documentation doesn't mention if stop() also resets to 0.0
_player = body
func _on_detection_exited(body: Node) -> void:
# super() doesn't work(?)
if body is Player:
_shoot_timer.stop()
_player = null
```
I had to move everything in `Mob`'s `_ready()` to it's own public `initialize()` function because `super()` didn't work. Why does `super()` not work on `_ready()`? and my detection enter/exit functions as well?10Mar. 06, 2025
My mob don't want to shoot mePixAngelI don't understand why my mob don't want to shoot the player. I've been looking for this issue for two hours now... and nothing
I share all my scripts, if anyone has an idea of what I'm doing wrong :
mob_2.gd:
```gdscript
class_name Mob2 extends Mob
@onready var area_2d: Area2D = %Area2D
@onready var weapon_2: AutoWeapon = $Marker2D/Weapon2
@onready var _cool_down_timer: Timer = %CoolDownTimer
func _ready() -> void:
super()
_cool_down_timer.wait_time = 1.0
_cool_down_timer.timeout.connect(func () -> void:
if _player != null:
weapon_2.shoot()
)
_cool_down_timer.start()
func _physics_process(delta: float) -> void:
var desired_velocity = Vector2.ZERO
if _player != null:
var direction = global_position.direction_to(_player.global_position)
var distance = global_position.distance_to(_player.global_position)
desired_velocity = direction * max_speed
weapon_2.look_at(_player.global_position)
velocity = velocity.move_toward(desired_velocity, acceleration * delta)
move_and_slide()
```
bullet_2.gd:
```gdscript
class_name Bullet_2 extends Area2D
@onready var _destroy_sound: AudioStreamPlayer = %AudioStreamPlayer
@export var max_speed := 950.0
@export var max_range := 1200.0
@export var damage := 1
@export var target_player : bool :
set = set_target_player
var traveled_distance := 0.0
func _ready() -> void:
body_entered.connect(func (body : Node) -> void:
if body is Mob2 or body is Player:
body.health -= damage
_destroy()
)
set_target_player(target_player)
func _physics_process(delta: float) -> void:
var direction = Vector2.RIGHT.rotated(rotation)
var velocity = direction * max_speed
position += velocity * delta
traveled_distance += max_speed * delta
if traveled_distance > max_range:
_destroy()
func _destroy() -> void:
set_physics_process(false)
queue_free()
func _on_body_entered(body : Node):
if body is Player:
body.health -= damage
_destroy()
func set_target_player(value : bool) -> void:
target_player = value
const PLAYER_PHYSICS_LAYER = 1
const MOB_PHYSICS_LAYER = 3
set_collision_layer_value(MOB_PHYSICS_LAYER, not target_player)
set_collision_layer_value(PLAYER_PHYSICS_LAYER, target_player)
```
weapon2.gd:
```gdscript
class_name AutoWeapon extends Weapon
@export var bullet_2 : PackedScene = null
@onready var _cool_down_timer: Timer = %CoolDownTimer
func _physics_process(delta: float) -> void:
return
func shoot() -> void:
var new_bullet : Bullet_2 = bullet_2.instantiate()
get_tree().current_scene.add_child(new_bullet)
new_bullet.target_player = true
new_bullet.global_position = global_position
new_bullet.global_rotation = global_rotation
new_bullet.rotation += randf_range(-PI / 30.0, PI / 30.0)
```
