the problem with bullets...

I have been using this website for my shooting code: https://mega.nz/#F!dkklTQiR!WL25e1TKLmhYKQT2RpIXNA
when I use this it lets me have a limited time with the bullet and its clones, or i get to keep the bullet and all its clones. here is the code that uses bullet and shoots it:

Code (JavaScript):

1. static var ammo = 100;
2. static var maxAmmo = 100;
3. var key : String = "mouse 0";
4. var bullet : Rigidbody;
5. var speed : float = 1000;
6.  
7. function Update () {
8.     if(Input.GetKeyDown(key)){
9.         if(ammo > 0){
10.             shoot();
11.         }
12.     }
13. }
14. function shoot(){
15.     var bullet1 : Rigidbody = Instantiate(bullet, transform.position, transform.rotation);
16.     bullet1.AddForce(transform.forward * speed);
17.     ammo --;
18. }
19.  

is there a way that i can delete the clones after a certain amount of time??? i see people doing it, but i have no idea... thanks!

 

Code (csharp):

1. // After you instantiate the bullet
2. Destroy(bullet1.gameObject, destroyDelay);

 

thank you.

 

You might want to consider looking here: https://unity3d.com/learn/tutorials/topics/scripting/object-pooling?playlist=17117

 

What he said.

Object pooling might sound a bit complex at first, but it is an extremely good habit to get into (and if you ever plan on releasing your game on a mobile device, it's probably a must). Just yesterday, I rewrote my game to replace instantiation with object pooling and my FPS tripled.

With instantiation, you create a copy of the desired object every time you need one and destroy it when you no longer need it. Doing so with too many objects (bullets are an excellent example) will slow the game down over time.
