Hello everyone, hope you all are having a nice day. I’m currently developing a shmup(not a serious project, just making it to learn) and I’ve encountered a problem. I’m trying to make a type of bullet that is shot in the direction of the player, but it currently just flashes in and disappears. Here is my code:
extends Area2D
var speed = 300
var player = preload("res://scenes/player.tscn")
func _process(delta):
var playerInstance = player.instantiate()
var direction = playerInstance.position - position
position += direction * speed * delta
func _on_area_entered(area):
if area.is_in_group("Player"):
queue_free()
Again, the bullet does spawn(the spawning is handled by a different script), but it disappears right after. If anyone has an idea of how to solve this, please, hit me up. I couldn’t find a tutorial or piece of documentation to help, so any ideas are welcome
var player = preload("res://scenes/player.tscn")
func _process(delta):
var playerInstance = player.instantiate()
This would make a new player every frame, it’s not added as a child so it wont be shown and I think will be freed automatically soon after. Instantiate creates a new thing from a scene.
Could use groups to find the player, though it’s best to store the result.
var playerInstance
func _ready() -> void:
playerInstance = get_tree().get_first_node_in_group("Player")
func _process(delta: float) -> void:
var direction = playerInstance.position - position
position += direction * speed * delta
func _on_area_entered(area):
if area == playerInstance:
queue_free()
I’ve refined my code a bit more and arrived at this:
extends Area2D
var speed = 300
var playerInstance
var direction
func _ready():
playerInstance = get_tree().get_first_node_in_group("Player")
func _process(delta):
direction = (playerInstance.position - position).normalized()
position += direction * speed * delta
func _on_area_entered(area):
if area.is_in_group("Player"):
queue_free()
Unfortunately, the bullet now follows the player(something I don’t want to happen) instead of just initially going in his direction edit
Putting the “direction = (playerInstance.position - position).normalized()” part in the _ready function gave me some odd behavior, which is to say, it didn’t work
I tried this. It didn’t work. Oddly, the bullets didn’t seem to be aiming at the player(especially when the player was to the left or top of the origin of the bullet. The bullets don’t go there at all). Even it didn’t quite work, I’d like to thank you for offering help : D
Could you post how the bullets are instantiated? _ready is called when you use add_child so maybe you need to set the bullet position before adding them as a child.
