So my meteor gets destroyed when i hit it with my missile. How would i make it respawn every time the original one dies?

Respawning
Bounce time Check out the ball class in this scenario
From your other discussion thread, I see that the meteors gets hit more than once, getting smaller each time. Do you have more than one meteor coming out of each hit? or is the only change per hit the scaling down in size or removal of the meteor?
That is, aside from your attempt to re-spawn a new meteor.
If only scaling down and removing, then the scenario Game/maniac suggests to check out would probably be sufficient.
i couldn't get the shrinking part to work with the disappearing part so i scrapped that idea until i am a bit better at java. Its just a simple case of missile hits meteor, meteor dissapears.

Bounce time Check out the ball class in this scenarioThe easiest thing to do, is instead of remove one and adding another, just re-locate the one anywhere
See the 'Greenfoot' class API in the documentation here .
int x = Greenfoot.getRandomNumber(getWorld().getWidth()); // get a random x location int y = Greenfoot.getRandomNumber(getWorld().getHeight()); // get a random y location setLocation(x, y); // re-locate meteor
It works but it dosen't look very smooth. Maybe if i added some kind of explosion where the missile hits the meteor it would look better. Could you direct me to a tutorial for explosions?
You could check out this scenario.
Or, I believe that the 'Lunar Landing' scenario that comes with greenfoot has an explosion in it; you could check it out.
You could also check out this scenario which creates debris when the rock explodes

So, yo my homies. Where do you put that there code up there?You need to prefix line 3 with the meteor object that is intersecting the actor.
An example intersecting detection with respawn:
Meteor meteor=(Meteor) getOneIntersectingObject(Meteor.class); // get random x and y meteor.setLocation(x, y);
so im using this for the Little Crab scenario instead where I want the worm to relocate ("respawn") every time the Crab eats it.
However, it doesn't seem to be working:
private void eatWorm()
{
Actor Worm;
Worm = getOneObjectAtOffset (0,0,Worm.class);
if(Worm != null)
{
Worm worm = getOneIntersectingObject (Worm.class);
int x = Greenfoot.getRandomNumber(getWorld().getWidth()); // get a random x location
int y = Greenfoot.getRandomNumber(getWorld().getHeight()); // get a random y location
setLocation(x, y); // re-locate meteor
counter.add(1);
Greenfoot.playSound ("eating.wav");First, let me say that it is customary to start variable (aka field) names with lowercase letters. It gets a litle confusing for those looking at your code when you use the same name for a class as well as a field ('Worm'). Next, you already have the intersecting object in the field 'Worm' when you (again) get it in line 7. Finally, line 10 does not relocate the Worm object, but relocates the Crab object instead. The following would be more what you need:
private void eatWorm()
{
Actor worm;
worm = getOneObjectAtOffset (0,0,Worm.class);
if(worm != null)
{
int x = Greenfoot.getRandomNumber(getWorld().getWidth());
int y = Greenfoot.getRandomNumber(getWorld().getHeight());
worm.setLocation(x, y);
counter.add(1);
Greenfoot.playSound ("eating.wav");
}
