Cheers!

In general, it is usually pretty helpful to include some of your code, even if it is just generalized to the specific issue you are experiencing.
# SomeNode.gd
func _on_button_pressed() -> void:
var my_var = "something" # this is not accessible outside of this function call
# other stuff...
If what you are asking is to retrieve my_var from outside that function call, unfortunately it doesn’t work like that. What you could do is have something like this
# SomeNode.gd
var my_var # declare this as a node-level property
func _on_button_pressed() -> void:
self.my_var = "something"
# other stuff...
and
# AnotherNode.gd
func some_function() -> void:
var some_node = load("res:///path/to/SomeNode.gd").new()
some_node._on_button_pressed()
var value_from_node = some_node.my_var
Ok, here’s some of my code :). Trying to trigger an area2d and rolling a dice to set the outcome.
Got a ‘Use’ button wich, when pressed, change the cursor to a lil hand, and i want to trigger the area2d only with this custom cursor. Here’s the button’s script to change the cursor:
extends Button
var cursor = load("res://Textures/Icons/UseC.png")
var cursor_state = "normal"
func _on_Use_pressed():
Input.set_custom_mouse_cursor(cursor)
var cursor_state = "selecting"
func _input(event):
var cursor_state = "selecting"
if event is InputEventMouseButton and event.pressed:
if event.button_index == BUTTON_RIGHT and cursor_state == "selecting":
Input.set_custom_mouse_cursor(null)
cursor_state = "normal"
And here’s the collisionshape’s script that roll my dice and trigger the area2d only with the custom cursor:
extends CollisionShape2D
onready var cursor_state = get_parent().get_parent().get_parent().get_parent().get_parent().get_parent().get_parent().get_node("Use").cursor_state
func _ready():
randomize()
func _physics_process(delta):
if Input.is_action_just_pressed("ui_accept"):
_on_Use_pressed()
func _on_Use_pressed():
roll_a_dice(1, 100)
func roll_a_dice(minimum, maximum):
var roll = randi() % (maximum-minimum+1) + minimum
print(roll)
func _on_Area2D_input_event(viewport, event, shape_idx):
if event is InputEventMouseButton and event.pressed and event.button_index == 1:
if cursor_state = "selecting"
if roll <= GlobalP.charm:
print("okokok")
Trouble are the ‘roll’ on func area2d wich isn’t declared, though in the same script, and the 'if cursor_state = “selecting” just before, wich is an unexpected assign…
Think that i have solved the issue of gettin this var from the button node, but i can’t be sure…
If you could see through it, meanwhile i’ll tinker with your data, and btw, what do you think of that method to get a var from outside with a dictionary?: link
