Powerup Pickup & Sprite Change Assistance

Question

Hi! I’m a very green indie dev making a 3D platformer and the goal is to have the goose approach an object, pick it up (& queue free it) which will then change the sprite so that it’s holding the powerup, which they can then use, (float powerup) and once they land again they turn back into a regular goose. I got my code to work ONCE and then never again, can someone help me figure out what I’m doing wrong here?

In the powerup:
[normal first few lines of base code]

func _on_area_3d_body_entered(body: Node3D) -> void:
	if body.is_in_group("player"):
		body.carry_nut()
		queue_free()

This so far has allowed me to change the sprite upon pickup and causes the powerup to go away, where I’m struggling is that once I’m in the carry_nut() state, I can’t access the powerup in its code in my playerscript:

In the playerscript:

@export var is_goose = true #base goose state
@export var has_nut = false #change to carrying nut
@export var is_plane = false #is paper plane

[usual physics, move_and_slide, etc]

func become_goose():
	is_goose = true
	sprite_3d.texture = load("res://goose.png")

func carry_nut():
	has_nut = true
	print("i have the nut!")
	sprite_3d.texture = load("res://Headshot.png")

func fly():
	if has_nut and Input.is_action_just_pressed("use item"):
		is_plane = true
		print("fly!")
		fly_up()
	if Input.is_action_just_released("use item"):
		fly_down()
	if is_plane and is_on_floor():
		become_goose()

func fly_up():
	sprite_3d.texture = load("res://plane.png")
	velocity.y += 10

func fly_down():
	velocity.y -= lerp(2, 1, 0.5)

It isn’t recognizing my keystroke as an input in fly(). Any help would be greatly appreciated, as it did what i wanted it to do once, then stopped

Thanks,

func fly():
	if has_nut and Input.is_action_just_pressed("use item"): # 1
		is_plane = true # set to true, so if #2 can run
		print("fly!")
		fly_up()
	if Input.is_action_just_released("use item"):
		fly_down()
	if is_plane and is_on_floor(): # 2
		become_goose()

If I understand your problem correctly it seems like your if statements should be elif instead. The fly function is run from top to bottom and each if along the way is checked. When you press “use item” and you are on the floor then you will become_goose immediately.

When you use elif it ensures only one if statement will evaluate for that function’s run.

func fly():
	if has_nut and Input.is_action_just_pressed("use item"):
		is_plane = true
		print("fly!")
		fly_up()
	elif Input.is_action_just_released("use item"):
		fly_down()
	elif is_plane and is_on_floor():
		become_goose()

Thank you so much! I had fiddled with elif’s a little bit but this fixes it.
