Hello, I made a script here that I want to give you more ammo when you collide with it. But I keep getting this error: Assets/AmmoPickup.js(14,9): BCE0005: Unknown identifier: ‘ammo’.
Here is the code for the destroy and give ammo:

(AmmoPickup.js)

var playerObject : GameObject;

private var myGO : GameObject;

function Start()
{
    myGO = gameObject;
}

function OnTriggerEnter (other : Collider) {
    if (!other.CompareTag("Player")) return; //Check that it's the player that triggers else exit the function
    myGO.active = false; //Disable this GameObject
	ammo.GetComponent(Ammo).ammo += 10;
	
	{
	ammo = GameObject.Find("First Person Controller").GetComponent(Ammo);
	}
}

and here is the ammo script:

(Ammo.js)

var ammo : float;
var fireRate : float = 0.5;
var style : GUIStyle;

private var nextFire : float = 0.0;
private var shooting : boolean = true;
private var flames : boolean = true;

function OnGUI() {
	
	GUI.color = Color.red;
	GUI.Label(Rect(20, 20, 200, 200), "MANA: " + ammo, style);
		if(Input.GetMouseButtonDown(0) && Time.time > nextFire){
			nextFire = Time.time + fireRate;
				ammo -= 1;
				
			{
				if(ammo < 0)
					shooting = false;
					flames = false;
				
			}
		}
	
	if(shooting == false){
		
		GameObject.Find("Actual").GetComponent(MagicShoot).active = false;
		GameObject.Find("small flames").active = false;
	}
	
	else
	{
		GameObject.Find("Actual").GetComponent(MagicShoot).active = true;
		GameObject.Find("small flames").active = true;
	}
	
}

Got it. I just needed to replace “ammo.GetComponent(Ammo).ammo += 10;” with “GameObject.Find(“First Person Controller”).GetComponent(Ammo).ammo +=10;”. Here is the final code:

(AmmoPickup.js)

var playerObject : GameObject;
var audioNoise : AudioClip;

private var myGO : GameObject;

function Start()
{
    myGO = gameObject;
}

function OnTriggerEnter (other : Collider) {
    if (!other.CompareTag("Player")) return; //Check that it's the player that triggers else exit the function
    myGO.active = false; //Disable this GameObject
	GameObject.Find("First Person Controller").GetComponent(Ammo).ammo +=10;
	audio.PlayOneShot(audioNoise);
}
