Hi guys, i need help. i wanted to make a PvP spaceship game with two players shooting at each other from the side of the screen. I have the shooting part down but i the bullets currently spawn in a stream that looks more like lazer at this point. my code for player 1 shooting currently looks like this 
 public void shoot()
    {
        
        if (Greenfoot.isKeyDown("space"))
        { 
            getWorld().addObject (new Bullet(), getX(), getY());
           }
                
    }
How would i make them spawn at something like 1 second intervals?

Add a timer int field. Anytime a shot is fired, set it to some nominal value (maybe somewhere around 50 to 60 -- possibly). If the value is greater than zero, decrease it value by one. Only shoot if the key is down AND the value of the timer field is zero.

Timer int field? so it doesn't necessarily have to be a simpletimer class?

No special class is needed. I mean, you could use a class for the timer, but a field is all that is needed provided you are not displaying the running values of the timer.
