Shot shot = new shot();  
             // set the rotation  
             // add it to the world
        {
           Shot.setRotation(getRotation()); 
        }

Yes, that's the code button. But now, indent your code right for the forum and remove this:

{
  Shot.setRotation(getRotation());
}

Shot shot = new shot();  
// set the rotation

Do you really have a Shot class, which is EXACTLY called Shot?

#

OOOO, I didn't see :). You mustn't create a Shot in the shot itself, that code was meant for another class: the class which fires the shots.

#

Whelp its in the class that fires the shot.. but different error

Shot shot = new Shot();    
// set the rotation    
// add it to the world

"New shot" is giving me error: cannot find symbol - constructor Shot() should i change Shot to my others actor name "Blip" or is it something else?

No, you wrote your own constructor:

public Shot(Blip myShip)  
{  
this.myShip = myShip;  
Shot shot = new shot();    
// set the rotation    
// add it to the world
}

Instead of:

new Shot();

You now have to put a Ship object between the ()

ThinkingPainter

so

Shot shot = new shot(Blip); myShip);      
// set the rotation      
// add it to the world

it needs to look like this basically?
