No, like this:

Ship ship = new Ship();
Shot shot = new Shot(ship);

I'm sorry, Ship should be Blip.

Change first line correct 2nd line not so much

Shot shot = new Shot(ship);

error: cannot find symbol - variable ship. I changed it to Blip, Shot also and gives me same error code.

This code should work:

Blip blip = new Blip();
Shot shot = new Shot(blip);

Were good there!!! just its still shooting the Shot in a straight line :P

I actually wonder why you don't understand this, I see this in your code:

getWorld().addObject(new Shot(this), getX(), getY());

That's almost what you want! You only have to change it to this:

Shot shot = new Shot(this);
shot.setRotation(getRotation());
getWorld().addObject(shot, getX(), getY());

Duhh, you didn't implement setting the rotation...

i dont understand it because ive just started coding a couple days ago, sorry i have no idea what anything means yet unlike someone whose been studying this for years, i appreciate you help here, most of the stuff that you see in my code is me copying and pasting

I think you better start on a simpler scenario, if you're still a beginner...

{    
       Blip blip = new Blip();  
       Shot shot = new Shot(blip);
       shot.setRotation(getRotation());  
       getWorld().addObject(shot, getX(), getY());
       // set the rotation      
      // add it to the world     
        
    }

this just made me fire repeatedly and its still firing in a straight line

Then, it's probably because the rotation of the blip is 0.

It is a lot easier when you learn it with an easier scenario.
