Giving the player ammo

Question

Hi, I have a script called "Stats" that setups the games variable such as the health, ammo, etc. The script:

 static var statHP : float = 100;
 static var statMaxHP : float = 100;
 static var gunAmmo = new Array();
 function Awake(){
     gunAmmo[0] = 10;
     gunAmmo[1] = 50;
 }

I'm not sure if I set up the array correctly... Anyway, before creating/firing a bullet, I check the ammo count for the current weapon. Each weapon has a variable gun which I use to check the ammo count. The script for creating the bullet(just a part):

 if (Input.GetButton("Fire1") && Stats.gunAmmo[gun] > 0 && timer == 0){
     Instantiate(bullet,transform.TransformPoint(Vector3(0,0,zOff)),transform.rotation);
     Instantiate(gunfire,transform.TransformPoint(Vector3(0,0,zOff)),transform.rotation);
     timer = wait;
     Stats.gunAmmo[gun] --;
 }

I use that and I get the error:

 Assets/Scripts/Create bullet.js(12,30): BCE0049: Expression 'Stats.gunAmmo.get_Item(self.gun)' cannot be assigned to.

So I'm guessing either you can't do anything with arrays outside of the script that contains it, or I created the array incorrectly. Could any help me please?

Did you give your array a size (or length)?

I've tried putting gunAmmo.length = 2; inside Awake, but it still gave me the same error.

Hmm.. maybe this would be better.

static var gunAmmo = new int[2];

It doesn't give me an error or anything, but now for some reason the weapon doesn't create/fire bullets anymore... I'm assu$$anonymous$$g this is how I should set it up?

static var gunAmmo = new int[2];

function Awake(){
gunAmmo[0] = 10; gunAmmo[1] = 50; }

That looks good, so I don't think the issue is your array anymore.

Side note: Tracking ammo in a global variable is a little strange. Wouldn't it make more sense to have a "Gun" component with ammo as a datamember?

So it may just be my firing script? I'll go mess around with it.

I'm used to using arrays/global variables for ammo and stats, plus I'm needing to save and load the variables, so I'll be using global variables for now.

EDIT: By datamember I'm assu$$anonymous$$g variables in scripts(var blah : int;) right?

Try setting

 gunAmmo = new Array();

in the awake function.

Something like:

 function Awake(){
     gunAmmo = new Array();
     gunAmmo[0] = 10;
     gunAmmo[1] = 50;
 }

Doing that I get the error: Assets/Scripts/Create bullet.js(8,47): BCE0019: 'gunAmmo' is not a member of 'Stats'.
