I want my projectile to dissapear when it hits something, and it does, but it gives me the terminal window:
java.lang.IllegalStateException: Actor not in world. An attempt was made to use the actor's location while it is not in the world. Either it has not yet been inserted, or it has been removed.

Here is the "Plasma" (the name of the projectile)'s code:
import greenfoot.*;
import java.awt.Color;
public class Plasma extends Actor
{
public void act()
{
move();
shootUFO();
shootAsteroid();
shootMissile();
atEdge();
}
public void move()
{
move (30);
}
public void shootUFO()
{
Actor UFO = getOneIntersectingObject(UFO.class);
if (UFO!=null)
{
World Level1 = getWorld();
Level1.removeObject(UFO);
Level1 level1 = (Level1) Level1;
Level1.removeObject(this);
}
}
public void shootAsteroid()
{
Actor Asteroid = getOneIntersectingObject(Asteroid.class);
if (Asteroid!=null)
{
World Level1 = getWorld();
Level1.removeObject(Asteroid);
Level1 level1 = (Level1) Level1;
Level1.removeObject(this);
}
}
public void shootMissile()
{
Actor Missile = getOneIntersectingObject(Missile.class);
if (Missile!=null)
{
World Level1 = getWorld();
Level1.removeObject(Missile);
Level1 level1 = (Level1) Level1;
Level1.removeObject(this);
}
}
public void atEdge()
{
if(isAtEdge())
{
World Level1 = getWorld();
Level1.removeObject(this);
}
}
}
