Updating the values of a dictionary's keys

Question
I use a dictionary to stock the data of my game’s weapons, including the current ammo count, like these:

var weapons = {
		1 : {
			name = "Type 45 pistol",
			damage = 1,
			currentAmmo = 15,
			fireAnimation = "pistol_fire",
			idleAnimation = "pistol_idle",
			pellets = 1,
			dispersion = 0,
			rateOfFire = 0.9,
			equipped = true
		},

But I don’t manage to update the ammo count (currentAmmo) when taking a ammo pick-up, who use this line:

WeaponDictionary.weapons[weaponNumber].currentAmmo += ammo

What I’m doing wrong ? Should I use another method ?
Thank

Hi,

The same code works fine on my side:

func _ready():
	var weapons = {
		1 : {
			name = "Type 45 pistol",
			damage = 1,
			currentAmmo = 15,
		}
	}
	
	weapons[1].currentAmmo += 3
	print(weapons[1].currentAmmo)  # Output: 18

Here’s what I would do, in order (you may have done some of these things already):
1/ Check if the code is actually being executed (you can add a print for that).
2/ Check if weaponNumber has a correct value.
3/ Check if ammo is not equal to 0 (the code may work but adding 0 doesn’t do anything).
4/ Check if you’re changing the correct dictionary (could be a duplicated version of another one).

Let me know if that helps.

Ok, weaponNumber was not correct, it is now and it work. I feel dumb but thank.

You’re not, don’t worry, everybody does mistakes like this
Just remember to always look for the most basic things first with simple prints, will same you some headaches with debugging your code.

Glad I could help.
