How to edit export var from diffrent script

Bat-boy

I have an export var on a node and on a different script I want to change it, how do I do it?

You can access it like a normal variable I believe. The export just lets you modify it in the editor.

But when I use node.var = 10 it doesn't work

Is that the actual code? You can't name a variable var, as that is a restricted keyword.

well no, the actual code is onready var playerSpeed = PlrVar.speed playerSpeed = 4

Is PlrVar the name of a node? If it's a child of the node to which that script is attached, change the code to: onready var playerSpeed = get_node("PlrVar").speed or: onready var playerSpeed = $PlrVar.speed

Variables for basic objects like int are just simple values (copies). You can get them no problem (but you get the value at the time you get it, not for future updates), to set them you have to set the value through the original reference. Updating a copy of the value does not update the original. So if you want to set the value (or read it after it might have changed), you have to do PlrVar.speed every time.

Do u mean I can only update it in its original script?

cybereality

No you can update it anywhere, but if you want to update it in another script, it must be through a reference (which you get from get_node() or $). Updating a copy of a variable does not update the original.

# Player
var speed = 12

# Enemy
var player_speed = get_node("Player").speed
print(player_speed) # prints 12
player_speed = 32
print(player_speed) # prints 32
print(get_node("Player").speed) # prints 12, original variable was not updated
get_node("Player").speed = 47
print(get_node("Player").speed) # prints 47, original variable was updated
print(player_speed) # prints 32, variable copy was not updated
