i looked in both examples but i dont understand where i should insert the debris class into my code to make it spawn 1 every time an asteroid dies. I’d apreciate if you can have a look and explain for my example where i should add it.

`class Bullet `

in this class, there is a method where the explosion starts. It is called ` void explode () {` .

Here the debris / shrapnels / missiles are added to the ArrayList `missiles`. Yeah. Call it where YOUR asteroid dies.

In draw also call `ExplosionManager()` to let the debris fly.

before setup():

```auto
// for explosions (these are actually Shrapnels)
ArrayList <Explosion> missiles; 

```

IN setup():

```auto
  // explosions: Create an empty ArrayList
  missiles = new ArrayList<Explosion>();

```
