I am making a horror game and it has a sanity meter, i want it to recharge as you move and if you stand to still it will start to drop, heres my code , its getting stack overflowed?

var sanity = 100

func _ready():
	subtractsanity()

func subtractsanity():
	if Input.is_anything_pressed():
		subtractsanity()
	else:
		await get_tree().create_timer(2.5).timeout
		sanity -= 1
		self.text = str(sanity)+"%"
		subtractsanity()

func _process(delta):
	if Input.is_anything_pressed():
		if sanity < 100:
			sanity += 1```

@sm3m

func subtractsanity():
    if Input.is_anything_pressed():
        subtractsanity()

Assuming your indentation looks like this the function will call itself forever if anything is pressed. Keep in mind scripts/functions run in their entirety and do not wait for events to happen, this will check if anything is pressed and restart the function, since no time has passed something is still pressed, so it restarts the function again and again until your stack overflows.

Make sure to format your pastes

Make it easier for new users to format and preview code in their posts

Posting here so to be linked for later use instead of re-typing this every time Make sure you paste scripts instead of screenshots. To properly format pasted code use three ticks ``` at the start and end of your paste like so: ``` # type or paste code here func _ready() -> void:     print("My ready function!") ``` Results in: # type or paste code here func _ready() -> void: print("My ready function!") Press the </> button or ctrl+e in the forum to create these ticks. [2024-09-02…

i fixed it , thanks, but i have another question. I have a couple cabins that will detect if the player enters them , how do i have them affect the sanity variable without reparenting a whole mess of things to mess a bunch of things up

Depends on how you want them to affect the player’s sanity. Why would it need reparenting?

i figured it out , i used get_parent() to get another node, i needed the player to be affected by an area3d
