Okay, so i made a missile, the thing is I need it to make an explosion animation upon colliding into a vehicle, the missile is the actor that'll explode and animate so if anyone knows how please help

  public void act() 
    {

        Actor a = this.getOneIntersectingObject(Vehicle.class);
        if( a != null)
        {
            
            Greenfoot.playSound("Explosion.mp3");
            this.setImage("Explosion.png");
            Greenfoot.delay(5);
            World myWorld = getWorld();
            CarWorld carworld = (CarWorld)myWorld;
            Counter counter = carworld.getCounter();
            counter.addScore2();
            getWorld().removeObject(this);
            return;
            

        }
        
        Actor b = this.getOneIntersectingObject(Cop.class);
        if( b != null)
        {
            Greenfoot.playSound("Explosion.mp3");
             this.setImage("Explosion.png");
            Greenfoot.delay(5);
            getWorld().removeObject(this);

            World myWorld = getWorld();
            CarWorld carworld = (CarWorld)myWorld;
            Counter counter = carworld.getCounter();
            counter.addScore2();
            return;

        }
        turn(10);
        setLocation(getX(), getY()-4);
        if ( getY() <= 0 ) getWorld().removeObject(this); 

    }    
}

You want an explosion animation. How exactly should that look? Do you have different explosion images which should be shown or do you want fragments flying around?

fragments flying around

Create a new class. In the constructor, create a small image with a random color. Give it a random starting direction and speed. Then in the act method, specify the rules for moving (either apply gravity and/or make it disappear after a certain amount of time). Whenever there is an explosion, add a bunch instances of this class at this position.

hmmmm.... can you make an example? i have no gravity but its a top view game where the objects around the player go the same speed as commanded by the player class

This is the code for the Debris, but it only goes down, it spawns in four spots around the missile or actor but they dont spread, they only move down, i need it to move at all for corners and de-spawn before hitting a wall or else they'll get stuck, and i also need it to move down at the speed of the player as they spread. Any examples?

public class Debris extends Actor
{ 
   public void act()
   {
       move(5);
            
        setLocation( getX(), getY() + Car.speed*CarWorld.SPEED_MULTI  );
        if ( getY() >= getWorld().getHeight()-20 )
        {World myWorld = getWorld();
         
              
        getWorld().removeObject(this); 
    }   
    
   
       
    }
     protected void setLocation(double x, double y)
    {
        super.setLocation( (int)Math.round(x), (int)Math.round(y) );
    }
}

And it might need a timer because they need to de-spawn quickly since its gonna animate and explosion and maybe a collision for a wrecked car
