get_node() -- Access variables

Question

My tree:
-world
--player
---sprite
--sword
---sprite

Hi. I want to access sibling node(player -- sword)
player script:

var health=100

sword script:

onready var variable1=getnode("/root/world/player")
var playerhealth=variable1.health
func ready():
print(playerhealth)

i am getting a mistake== Node not found: /root/world/player.

Please help. Thanks

A better way to access the node would be by executing:

onready var player = $Player

such that you can call:

player_health = player.health

Doing it this way is more standard and can give you access to any of the children of the script holding node.

Sorry, but not work. This time I am getting a new error. == Invalid get index "health" (on base: "Nil")

New sword script:
onready var player=$player
var health=player.health

func _ready():
print(health)

After the ‘$’ sign, the word need the be the name of the node you want to reference, is the node called ‘player’ exactly like that? (No capitals etc)

---

Yes , it is. .

Do you want a screenshot?

So it looks as though the sword and the player are not a child of each-other. You’ll need to access the tree as a whole and then your player

Try using get_tree() and then attaining a child in the tree

A screenshot would be helpful

Yes. THe Sword and the player not a child of each-other. How can I do what you're saying

---

Make the sword a child of the player and try the original plan, the sword is a part of the player I assume so really it should be a child of it

---

main scene == WORLD (Node 2d)
WORLD's childs == player , sword
player's childs== Sprite , CollisionBox2d
sword's childs== Sprite, CollisionBOx2d

The player and the sword are child of world.
if i can "Make the sword a child of the player" This time sword and player move the together.

---

Do they need to be separate?

---

Unfortunately yes

---

Can you put your code on google drive (or other so I can have a look please)?

Thanks

I have got it working! :)

So in your sword script you want something like this...

onready var player = get_parent().get_node("player")

func _ready():
    print(player.health)

and then clearly in you player script you need var health = 100 somewhere.

Let me know if this works!

WOOOOOWWWW! You are awesome. It's work. Thanks for everything.

No problem!
