Converting an Int to string still wont let me set it to a label text

Question

i have tried so many solutions but it just gives me an error or it wont set it at all

if Input.is_action_just_pressed("fire"):
        if currentWeapon == "Gun":
            gunAmmoLefttostr = String(gunAmmoLeft)
            gunAmmoLeft = gunAmmoLeft - 1
            gunAmmoLeftText.text = gunAmmoLefttostr
            print(gunAmmoLeft)

Answer 1

While I'm not sure where you're going wrong, I can assure you that the following code works as expected (sets the label's text to 1) assuming the node containing the script has a child label named Label.

func _ready():
    var int_var = 1
    $Label.text = String(int_var)

If you're getting an error, what does it say?

Comments

it says "Invalid set index 'text' (on base: 'int') with value of type 'float'."

That implies that the object you're attempting to set the text property on is an integer. That's certainly not what you want. In the above code, my $Label reference points to a Label control. In your case, your variable points to an integer value. For example, this will trigger that exact error:

var float_var = 1.0
var int_var = 1
int_var.text = String(float_var)

Your Label reference is wrong. If you can't find it, paste the code that's causing trouble, along with how you're setting the reference to the object that you're setting the text property on.

this is what the variable is onready var gunAmmoLeftText = get_parent().get_node("UI/HUD/Ammo/AmmoLeft")

---

This should be really simple, so we're still missing something. Please post the following:

• The entire script that's failing (formatted as code for the forum)
• A screenshot of your scene tree
• Indicate which node in the scene tree contains the (pasted) script

Or, better yet - if the project is available to look at, post a link to a download...

Alright i think i have a (temporary) solution, so using an onready var just doesn't do anything, not even an error/warning. using a var errors because it cant find it. but just pointing to the node through the statement and not the variable makes it work like intended. But if you want to review the code still here it is.

The problem in that code is in _ready.

func _ready():
    Input.set_mouse_mode(Input.MOUSE_MODE_CAPTURED)
    gunloc.set_as_toplevel(true)
    camera.fov = 91
    gunAmmoLeftText = gunAmmoLeft

Specifically, that last line, where your assign gunAmmoLeftText = gunAmmoLeft. I assume that gunAmmoLeft is an integer. So, from that point on, your gunAmmoLeftText variable is just an integer. So, when you later try to set its text property, you get the original error you reported.

jgodfrey is right, I will just add this tip! Since labels have a property text, if you name your labels as yourLabelText, you might missread it as yourLabel.text, leading to this kind of issues. I suggest LabelAmmoLeft or AmmoLeftLabel.

Answer 2

look at on base 'int' on your error, this means that you are trying to set the text property on something that is an int, where it should be a Label Node. So the problem is not on the code snippet you provided, but before. Make sure gunAmmoLeftText is actually refering to your desired Label.

this is what the variable is onready var gunAmmoLeftText = get_parent().get_node("UI/HUD/Ammo/AmmoLeft")
