Is the Object still there?

Unity Engine
1

Hey guys Im writing a script that counts how many turrets there are If there are no more turrets it destroys a gate but I cannont figure what does it say in java when a object was destroyed? heres my code

var TurretNumber: int = 10;
var TurretType : Transform;
function Update () 
{
  if (TurretNumber == 0)
  {
     Destroy(gameObject);
  }
}
2

what i did is whenever the turret is destroyed, the turret number would lose one number. so put his in the place with the death stuff related to the turret controllingScript.turretNumber -= 1; and in the controlling script use static var turretNumber : int = 10;

3

So Your saying put the The TurretType Var into:

var explosion : Transform;

function OnTriggerEnter(hit : Collider )
{
  if(hit.gameObject.tag == "ApcProjectile")
	{
	 Destroy(hit.gameObject);
	 var exp = Instantiate(explosion, gameObject.transform.position, Quaternion.identity);
	 Destroy(gameObject);
	}
}

But JM what if I it want to affect a diffrent type of turret?

4

yes, I am

5

what do you mean?

6

Call a function on the turret instead of using Destroy.

StuffThatBreaksTurrets

if ( hit.gameObject ) {
  var turret : Turret = hit.gameObject.GetComponent(turret);
  if ( turret ) {
    turret.Destroy();
  }
}

Turret.js

static var turrets : int;
function Start() { 
  turrets++;
}

function Destroy() {
  Destroy( gameObject );
  turrets--;
}

Then any object can ask how many Turrets remain with “if ( Turret.turrets == 0 )” or whatever.

7

I mean By that your saying to put the script with the turret control script and the turret death script
but what if I want a diffrent turret destroyed to get the gate destroyed

8

no, you do this:

static var turretNumber: int = 10;
var turretType : Transform;
function Update () 
{
  if (turretNumber == 0)
  {
     Destroy(gameObject);
  }
}

and then you put the -= part in the turret script like you had it.

9

Ok how about this:

var TurretNumber: int = 10;
var TurretType : Transform;
function Update () 
{
  if (TurretNumber == 0)
  {
     Destroy(gameObject);
  }
}
function Destroy()
{
  if (TurretType != null)
  {
  TurretNumber -= 1;
  Debug.Log(what will go in the debug log?)
  }
}
10

why are you calling the destroy function in the “gameManager” script? just do this:

static var turretNumber: int = 10;
var turretType : Transform;
function Update () 
{
  if (turretNumber == 0)
  {
     Destroy(gameObject);
  }
}

var explosion : Transform;

function OnTriggerEnter(hit : Collider )
{
  if(hit.gameObject.tag == "ApcProjectile")
	{
	 SendMessage("Destroy");
	}
}
	
function Destroy () {	
	Destroy(hit.gameObject);
	var exp = Instantiate(explosion, gameObject.transform.position, Quaternion.identity);
	Destroy(gameObject);
	controllingScript.turretNumber -= 1;
}
11

would it be possible to do it without the destroy function? like this:

var explosion : Transform;
function OnTriggerEnter(hit : Collider )
{
  if(hit.gameObject.tag == "ApcProjectile")
	{
	 Destroy(hit.gameObject);
	 var exp = Instantiate(explosion, gameObject.transform.position, Quaternion.identity);
	 Destroy(gameObject);
	 LevelGateControl.TurretNumber -= 1;
	}
}
12

yes, that would work fine

13

Nevermind, ninjas. :slight_smile:

14

Ok now before I end the thread how do I make it so I can change values of how many I want gone?

15

use this script instead:

var explosion : Transform;
var turretValue = 1;

function OnTriggerEnter(hit : Collider )
{
  if(hit.gameObject.tag == "ApcProjectile")
	{
	 Destroy(hit.gameObject);
	 var exp = Instantiate(explosion, gameObject.transform.position, Quaternion.identity);
	 Destroy(gameObject);
	 LevelGateControl.TurretNumber -= turretValue;
	}
}

then you can change the turret value

16

Well its not working becuase when I apply it to levelGate A number does not show that will let me change it

17

that is because it is a static variable, if it is static, you cant edit it that way. you have to do that through the script.

18

its like private var, except its public

19

try this:

static var turretNumber: int;
var turretType : Transform;
var turrets = 10;

function Update () {
  if (turretNumber == 0)
  {
     Destroy(gameObject);
  }
} 

function Awake () {
	turretNumber = turrets;
}
20

I know that and it was a static. Im wondering what could be the problem here is my code:

static var TurretNumber : int = 10;
function Update () 
{
  if (TurretNumber == 0)
  {
     Destroy(gameObject);
  }
}

And the on Turret collison:

[var explosion : Transform;
function OnTriggerEnter(hit : Collider )
{
  if(hit.gameObject.tag == "ApcProjectile")
	{
	 Destroy(hit.gameObject);
	 var exp = Instantiate(explosion, gameObject.transform.position, Quaternion.identity);
	 Destroy(gameObject);
	 LevelGateControl.TurretNumber -= 1;
	}
}
