Health Script

Question

Hey, I am kinda a beginner at scripting, closer to intermediate. I am getting an error and yes, I know that the script is called Bullet and all that stuff. Here is the error Assets/Scripts/Guns and Damaging/Gun.js(38,13): BCE0067: There is already a local variable with the name 'bullet'. And Here is the code #pragma strict

 var Health : int = 100;
 var bullet : GameObject;
 var damage : int;
 
 function Update () 
 {
     if(Health < 0)
     {
         Die();    
     }
 }
 
 function OnGUI ()
 {    
     GUI.Box(Rect(10,Screen.height - 150, 200, 145), "");
     GUI.Label(Rect(20,Screen.height - 140, 180, 125), Health + " / " + "100");
 }
 function OnTriggerEnter ( $$anonymous$$t : Collider ) 
 {
     if($$anonymous$$t.gameObject.tag == "RedBullet")
     {
         bullet = $$anonymous$$t.gameObject;
         TakeDamage();    
     }
     if($$anonymous$$t.gameObject.tag == "RedBullet")
     {
         bullet = $$anonymous$$t.gameObject;
         TakeDamage();    
     }
 }
 
 function TakeDamage()
 {
     var BulletScript : Bullet = bullet.GetComponent("Bullet");
     damage = BulletScript.Damage;
     Health -= damage;
 }
 
 function Die()
 {
     Debug.Log("I'm death");
     Network.Destroy(gameObject);
     var spawnObject : GameObject = GameObject.Find("SpawnManager");
     var spawnScript : SpawnManager = spawnObject.GetComponent("SpawnManager");
     spawnScript.Dead = true;
 }

Because you do not format your code properly ( the #pragma strict is not in the code segment ), I can't really tell w$$anonymous$$ch line is line 38.

If anyt$$anonymous$$ng in your script can be wrong, that somet$$anonymous$$ng is most probably the TakeDamage().

The line is var BulletScript : Bullet = bullet.GetComponent("Bullet");

I have copied your code and ran it. There is no error at all, just 1 warning.

My Make-shift Bullet Script

var damage : float = 5;

 function Update () 
 {
     transform.Translate( Vector3.forward * 3 * Time.deltaTime );
 }

The Health Script

pragma strict

 var health : int = 100;
 var bullet : GameObject;
 var damage : int;
  
 function Update () 
 {
     if(health < 0)
     {
        Die();    
     }
 }
  
 function OnGUI ()
 {   
     GUI.Box(Rect(10,Screen.height - 150, 200, 145), "");
     GUI.Label(Rect(20,Screen.height - 140, 180, 125), health + " / " + "100");
 }
 function OnTriggerEnter ( hit : Collider ) 
 {
     Debug.Log("trigger");
     if(hit.gameObject.tag == "RedBullet")
     {
        bullet = hit.gameObject;
        TakeDamage(); 
     }
     if(hit.gameObject.tag == "RedBullet")
     {
        bullet = hit.gameObject;
        TakeDamage(); 
     }
 }
  
 function TakeDamage()
 {
     var bulletScript : Bullet = bullet.GetComponent("Bullet") as Bullet;
     damage = bulletScript.damage;
     health -= damage;
 }
  
 function Die()
 {
     Debug.Log("I'm death");
     Network.Destroy(gameObject);
     /*var spawnObject : GameObject = GameObject.Find("SpawnManager");
     var spawnScript : SpawnManager = spawnObject.GetComponent("SpawnManager");
     spawnScript.Dead = true;*/
 }
