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.

I am trying to make a bomb that explodes, but when it leaves the world it breaks another line of code. anything wrong with this code? 
 if (isAtEdge())
        {
            setImage( myGif2.getCurrentImage() );
            move(-30);
            getWorld().removeObject(this);
        }
        else if(life <= 5)
        {
            setImage( myGif2.getCurrentImage() );
            move(-30);
        }
        if(life <= 0) 
        {
            setImage( myGif2.getCurrentImage() );
            move(-30);
            getWorld().removeObject(this);
            
        }
        if (isTouching(Boss.class))
        {
           setImage( myGif2.getCurrentImage() );
            move(-30);
            getWorld().removeObject(this);
        }
        else
        {
            life--;
            
        }

Add the following line immediately after each time you remove this (3 times): 
return;

It didn't work... this is my code now 
public void act() 
     {
        if (isAtEdge())
        { setImage( myGif2.getCurrentImage() );
            move(-30);
            getWorld().removeObject(this);
            return;
        }
        else if(life <= 5)
        {
            setImage( myGif2.getCurrentImage() );
            move(-30);
        }
        else if(life <= 0) 
        {
            move(-30);
            getWorld().removeObject(this);
            return;
        }
        else if (isTouching(Boss.class))
        {
           setImage( myGif2.getCurrentImage() );
            move(-30);
            getWorld().removeObject(this);
            return;
        }
        else
        {
            life--;
            
        }
        move(30);

There is no error message, it just doesn't work as it should.

I think it is because it removes the object immediately, but I want it to explode for at least 1 second beforehand, is there a way to delay the removal of the bomb?

An explosion is not a bomb. Use a separate Actor subclass for the explosion.

Do I make the explosion a subclass of the Bomb? Also, it says "method addObject in class greenfoot.World cannot be applied to given types: required: greenfoot.Actor, int, int found: java.lang.Class<Explosion> reason: actual and formal argument lists differ in length." The code I have is this 
if (isAtEdge())
        { 
            move(-30);
            getWorld().removeObject(this);
            getWorld().addObject(Explosion.class);
            return;
        }

The error message tells you what you need for the arguments of the addObject call on line 5 -- an Actor object and two int values (the coordinates where the actor should be placed; not a class. Also, you better add the explosion before removing the bomb or the bomb will lose its reference to the world and won't be able to place the bomb in it.

Everything works fine now, thanks! But The gif loops over and over instead removing itself. How do I make the explosion remove itself after the first loop of the animation? Thanks for all your help so far, though!
