spawning multiple instances of a scene with different rotations

bobodoustaud

So basically, i want to spawn multiple instances of a same scene with different rotations and locations. on the same processing tick. I tried multiple things but none worked like . Any help would be greatly appreciated.

This is my player code

extends KinematicBody2D

var bullet = preload("res://bullet/bullet.tscn")
# Declare member variables here. Examples:
# var a = 2
# var b = "text"
var speed = 250

# Called when the node enters the scene tree for the first time.
func _ready():
	set_physics_process(true)
	set_process(true)
func _physics_process(delta):
	if Input.is_action_pressed("ui_left"):
		move_and_collide(Vector2(-speed*delta,0))
	if Input.is_action_pressed("ui_right"):
		move_and_collide(Vector2(speed*delta,0))
	var bulletInstance = bullet.instance()
	bulletInstance.position=Vector2(position.x,position.y)
	get_tree().get_root().add_child(bulletInstance)
	bulletInstance.position=Vector2(position.x+20,position.y)
	get_tree().get_root().add_child(bulletInstance)

#func _process(delta):
	#if Input.is_action_just_pressed("fire"):
		#var bulletInstance = bullet.instance()
		#bulletInstance.position=Vector2(position.x,position.y-20)
		#get_tree().get_root().add_child(bulletInstance)

and this my bullet code

extends KinematicBody2D


var speed = 500

# Called when the node enters the scene tree for the first time.
func _ready():
	set_physics_process(true)
func _physics_process(delta):
	move_and_collide(Vector2(0,-speed*delta))
	if get_position().y>ProjectSettings.get_setting("display/window/size/height")-10 or get_position().y<-10:
		queue_free()

You have to call instance() for each object you want to spawn. In your code you are just adding the same object twice, which won't work.

    var bulletInstance = bullet.instance()
    bulletInstance.position=Vector2(position.x,position.y)
    get_tree().get_root().add_child(bulletInstance)
    var bulletInstance2 = bullet.instance()
    bulletInstance2.position=Vector2(position.x+20,position.y)
    get_tree().get_root().add_child(bulletInstance2)

You might also have to set position after it's been added as a child to the scene tree. In 3D it will not work unless it's already part of the scene.

yes, set it's position after adding it...just to avoid the !is_inside_tree() error. and adding it in a loop is a good way to do multiple things ion one pass.
