My custom function isn't working

Question

This is an excerpt of code I have for a game I've been working on:

var scene_number = 0

func _on_Area2D_input_event(viewport, event, shape_idx):
    if event is InputEventMouseButton:
         scene_number += 1
         print(scene_number)

func stop_music():
     if scene_number == 1:
         print("hello")

The scene number updates when I click on a sprite and I've confirmed this with a print function, so how come it won't print out "hello" when the scene_number == 1 (after one mouse click)

Comments

In addition to the answers you got, the scene_number var will also change from being 1 as two events actions happen during InputEventMouseButton

1. MouseButton pressed down
2. MouseButton press released

So if your stop_music function is being called maybe try

#if greater than or equal to
if scene_number >= 1: 
    print("hello")

Answer 1

Nowhere in your code snippet does stop_music() get called.

Answer 2

That would depend on when the stop_music() function is being called. Try to print something *before* the if statement, to see if the function is fired at the appropriate time.
