Access Var From Another GameObject

Questions & Answers
1

i need to access a variable from another game object. what i wan’t to happen is have a variable called kills go up by 1 every time the dead function is called by the script controlling the enemy prefab. here’s my script(javascript).

Health script for enemy:

var Health : int = 1;
var Type1Damage : int = 1;
var Type2Damage : int = 5;
var Type3Damage : int = 10;
var Blood : Transform;

function Start () 
{
}

function LateUpdate()
{
 if(Health <= 0)
 {
 Health = 0;
 Dead();
 }
}

function OnCollisionEnter(collision : Collision)
{
 if(collision.gameObject.tag == "Type 1")
 {
 Health -= Type1Damage;
 }
 
if(collision.gameObject.tag == "Type 2")
 {
 Health -= Type2Damage;
 }
 
 if(collision.gameObject.tag == "Type 3")
 {
 Health -= Type3Damage;
 }
}

function Dead()
{ 
 Destroy(gameObject);
 Instantiate(Blood, transform.position, transform.rotation);
}

GUI script for camera:

public var Kills : int = 0;

function Update () 
{
}
function OnGUI()
{
 GUI.Label(Rect(Screen.width / 2, 10, 60, 20), "" + Kills);
}

make it static:

static var Kills : int = 0;

then access it by the name of the script:

function Dead()
{ 
HealthScriptName.Kills++;
 Destroy(gameObject);
 Instantiate(Blood, transform.position, transform.rotation);
}

otherwise, you could create a var to store the player script:

var healthScript : HealthScript;

function Start(){
healthScript = GameObject.Find("Player").GetComponent(HealthScript);
}

then you access it with that:

healthScript.Kills++;
